Testing in Eclipse, with ADT
+
+ The ADT plugin lets you quickly set up and manage test projects directly in + the Eclipse UI. Once you have written your tests, you can build and run them and + then see the results in the Eclipse JUnit view. You can also use the SDK command-line + tools to execute your tests if needed. +
+
Testing in Other IDEs
+
+ The SDK command-line tools provide the same capabilities as the ADT plugin. You can + use them to set up and manage test projects, build your test application, + run your tests, and see the results. You use + the android tool to create and manage test projects, the Ant build system + to compile them, and the adb tool to install and run them. +

+ This topic explains how create and run tests of Android applications in Eclipse with ADT. + + with the basic processes for creating and running applications with ADT, as described in + Developing In Eclipse, with ADT. + + Before you read this topic, you should read about how to create a Android application with the + basic processes for creating and running applications with ADT, as described in + Developing In Eclipse, with ADT. + You may also want to read + Testing and Instrumentation, + which provides an overview of the Android testing framework. +

+

+ ADT provides several features that help you set up and manage your testing environment + effectively: +

+ +

+ If you are not developing in Eclipse or you want to learn how to create and run tests from the + command line, see + Testing in Other IDEs. +

+

Creating a Test Project

+

+ To set up a test environment for your Android application, you must first create a separate + application project that holds the test code. The new project follows the directory structure + used for any Android application. It includes the same types of content and files, such as + source code, resources, a manifest file, and so forth. The test application you + create is connected to the application under test by an + + <instrumentation> element in its manifest file. +

+

+ The New Android Test Project dialog makes it easy for you to generate a + new test project that has the proper structure, including the + <instrumentation> element in the manifest file. You can use the New Android + Test Project dialog to generate the test project at any time. The dialog appears just after you + create a new Android main application project, but you can also run it to create a test project + for a project that you created previously. +

+

+ To create a test project in Eclipse with ADT: +

+
    +
  1. + In Eclipse, select File > New > Other. This + opens the Select a Wizard dialog. +
    2. +
  2. + In the dialog, in the Wizards drop-down list, + find the entry for Android, then click the toggle to the left. Select + Android Test Project, then at the bottom + of the dialog click Next. The New Android Test Project wizard appears. +
    3. +
  3. + Enter a project name. You may use any name, but you may want to + associate the name with the project name for your Application. One + way to do this is to take the Application's project name, append the + string "Test" to it, and then use this as the test case project name. +
    4. +
  4. + In the Test Target panel, set + An Existing Android Project, click + Browse, then select your Android application from + the list. You now see that the wizard has completed the Test + Target Package, Application Name, and + Package Name fields for you (the latter two are in + the Properties panel). +
    5. +
  5. + In the Build Target panel, select the Android SDK + platform that you will use to test your application. Make this the same as the + build target of the application under test. +
    6. +
  6. + Click Finish to complete the wizard. If + Finish is disabled, look + for error messages at the top of the wizard dialog, and then fix + any problems. +
    7. +
+

+ +

+

Creating a Test Application

+

+ Once you have created a test project, you populate it with a test + Android application. This application does not require an {@link android.app.Activity Activity}, + although you can define one if you wish. Although your test application can + combine Activities, Android test class extensions, JUnit extensions, or + ordinary classes, you should extend one of the Android test classes or JUnit classes, + because these provide the best testing features. +

+

+ Test applications do not have an Android GUI. Instead, when you run the application in + Eclipse with ADT, its results appear in the JUnit view. If you run + your tests with {@link android.test.InstrumentationTestRunner InstrumentationTestRunner} (or a related test runner), + then it will run all the methods in each class. You can modify this behavior + by using the {@link junit.framework.TestSuite TestSuite} class. +

+ +

+ To create a test application, start with one of Android's test classes in the Java package {@link android.test android.test}. + These extend the JUnit {@link junit.framework.TestCase TestCase} class. With a few exceptions, the Android test classes + also provide instrumentation for testing. +

+

+ For test classes that extend {@link junit.framework.TestCase TestCase}, you probably want to override + the setUp() and tearDown() methods: +

+ +

+ Another useful convention is to add the method testPreConditions() to your test + class. Use this method to test that the application under test is initialized correctly. If this + test fails, you know that that the initial conditions were in error. When this happens, further test + results are suspect, regardless of whether or not the tests succeeded. +

+

+ The Resources tab contains an Activity Testing + tutorial with more information about creating test classes and methods. +

+

Running Tests

+
+
+

Running tests from the command line

+

+ If you've created your tests in Eclipse, you can still run your tests and test + suites by using command-line tools included with the Android SDK. You may want to + do this, for example, if you have a large number of tests to run, if you have a + large test case, or if you want a fine level of control over which tests are run at + a particular time. +

+

+ To run tests created in Eclipse with ADT with command-line tools, you must first + install additional files into the test project using the android tool's + "create test-project" option. To see how to do this, read the section + + Creating a test project in the topic + Testing in Other + IDEs. +

+
+
+

+ When you run a test application in Eclipse with ADT, the output appears in + an Eclipse view panel. You can run the entire test application, one class, or one + method of a class. To do this, Eclipse runs the adb command for running a test application, and + displays the output, so there is no difference between running tests inside Eclipse and running them from the command line. +

+

+ As with any other application, to run a test application in Eclipse with ADT you must either attach a device to your + computer or use the Android emulator. If you use the emulator, you must have an Android Virtual Device (AVD) that uses + the same target +

+

+ To run a test in Eclipse, you have two choices:

+
    +
  1. + Run a test just as you run an application, by selecting + Run As... > Android JUnit Test from the project's context menu or + from the main menu's Run item. +
    2. +
  2. + Create an Eclipse run configuration for your test project. This is useful if you want multiple test suites, each consisting of selected tests from the project. To run + a test suite, you run the test configuration. +

    + Creating and running test configurations is described in the next section. +

    +
    3. +
+

To create and run a test suite using a run configuration:

+
    +
  1. + In the Package Explorer, select the test + project, then from the main menu, select + Run > Run Configurations.... The + Run Configurations dialog appears. +
    2. +
  2. + In the left-hand pane, find the + Android JUnit Test entry. + In the right-hand pane, click the Test tab. + The Name: text box + shows the name of your project. The + Test class: dropdown box shows one your project's classes + test classes in your project. +
    3. +
  3. + To run one test class, click Run a single test, then enter your project + name in the Project: text box and the class name in the + Test class: text box. +

    + To run all the test classes, + click Run all tests in the selected project or package, + then enter the project or package name in the text box. +

    +
    4. +
  4. + Now click the Target tab. + +
  5. + Click the Common tab. In the + Save As pane, click Local to save + this run configuration locally, or click Shared to + save it to another project. +
    6. +
  6. + Optional: Add the configuration to the Run toolbar and the Favorites + menu: in the Display in Favorites pane + click the checkbox next to Run. +
    7. +
  7. + Optional: To add this configuration to the Debug menu and toolbar, click + the checkbox next to Debug. +
    8. +
  8. + To save your settings, click Close.
    +

    Note: Although you can run the test immediately by + clicking Run, you should save the test first and then + run it by selecting it from the Eclipse standard toolbar.

    +
    9. +
  9. + On the Eclipse standard toolbar, click the down arrow next to the + green Run arrow. This displays a menu of saved Run and Debug + configurations. +
    10. +
  10. + Select the test run configuration you just created. +
    11. +
  11. + The progress of your test appears in the Console view. + You should see the following messages, among others: + +
+

+ The test results appear in the JUnit view. This is divided into an upper summary pane, + and a lower stack trace pane. +

+

+ The upper pane contains test information. In the pane's header, you see the following + information: +

+ +

+ The body of the upper pane contains the details of the test run. For each test case class + that was run, you see a line with the class name. To look at the results for the individual + test methods in that class, you click the left arrow to expand the line. You now see a + line for each test method in the class, and to its right the time it took to run. + If you double-click the method name, Eclipse opens the test class source in an editor view + pane and moves the focus to the first line of the test method. +

+

+ The lower pane is for stack traces. If you highlight a failed test in the upper pane, the + lower pane contains a stack trace for the test. If a line corresponds to a point in your + test code, you can double-click it to display the code in an editor view pane, with the + line highlighted. For a successful test, the lower pane is empty. +

+ This document describes how to create and run tests directly from the command line. + You can use the techniques described here if you are developing in an IDE other than Eclipse + or if you prefer to work from the command line. This document assumes that you already know how + to create a Android application in your programming environment. Before you start this + document, you should read the document Testing and Instrumentation, + which provides an overview of Android testing. +

+

+ If you are developing in Eclipse with ADT, you can set up and run your tests +directly in Eclipse. For more information, please read Testing in Eclipse, with ADT. +

+

Working with Test Projects

+

+ You use the android tool to create test projects. + You also use android to convert existing test code into an Android test project, + or to add the run-tests Ant target to an existing Android test project. + These operations are described in more detail in the section Updating a test project. + The run-tests target is described in Quick build and run with Ant. +

+

Creating a test project

+

+ To create a test project with the android tool, enter: +

android create test-project -m <main_path> -n <project_name> -p <test_path>
+

+ You must supply all the flags. The following table explains them in detail: +

+ + + + + + + + + + + + + + + + + + + +
FlagValueDescription
-m, --main + Path to the project of the application under test, relative to the test application + directory. + + For example, if the application under test is in source/HelloAndroid, and you + want to create the test project in source/HelloAndroidTest, then the value of + --main should be ../HelloAndroid. +
-n, --nameName that you want to give the test project. 
-p, --pathDirectory in which you want to create the new test project. + The android tool creates the test project files and directory structure in this + directory. If the directory does not exist, android creates it. +
+

+ If the operation is successful, android lists to STDOUT the names of the files + and directories it has created. +

+

+ This creates a new test project with the appropriate directories and build files. The directory + structure and build file contents are identical to those in a regular Android application + project. They are described in detail in the topic + Developing In Other IDEs. +

+

+ The operation also creates an AndroidManifest.xml file with instrumentation + information. When you run the test, Android uses this information to load the application you + are testing and control it with instrumentation. +

+

+ For example, suppose you create the Hello, World tutorial application + in the directory ~/source/HelloAndroid. In the tutorial, this application uses the + package name com.example.helloandroid and the activity name + HelloAndroid. You can to create the test for this in + ~/source/HelloAndroidTest. To do so, you enter: +

+
+$ cd ~/source
+$ android create test-project -m ../HelloAndroid -n HelloAndroidTest -p HelloAndroidTest
+
+

+ This creates a directory called ~/src/HelloAndroidTest. In the new directory you + see the file AndroidManifest.xml. This file contains the following + instrumentation-related elements and attributes: +

+ +

Updating a test project

+

+ You use the android tool when you need to change the path to the + project of the application under test. If you are changing an existing test project created in + Eclipse with ADT so that you can also build and run it from the command line, you must use the + "create" operation. See the section Creating a test project. +

+

+ Note: If you change the Android package name of the application under test, + you must manually change the value of the <android:targetPackage> + attribute within the AndroidManifest.xml file of the test application. + Running android update test-project does not do this. +

+

+ To update a test project with the android tool, enter: +

+
android update-test-project -m <main_path> -p <test_path>
+ + + + + + + + + + + + + + + + + +
FlagValueDescription
-m, --mainThe path to the project of the application under test, relative to the test project + For example, if the application under test is in source/HelloAndroid, and + the test project is in source/HelloAndroidTest, then the value for + --main is ../HelloAndroid. +
-p, --pathThe of the test project. + For example, if the test project is in source/HelloAndroidTest, then the + value for --path is HelloAndroidTest. +
+

+ If the operation is successful, android lists to STDOUT the names of the files + and directories it has created. +

+

Creating a Test Application

+

+ Once you have created a test project, you populate it with a test application. + The application does not require an {@link android.app.Activity Activity}, + although you can define one if you wish. Although your test application can + combine Activities, Android test class extensions, JUnit extensions, or + ordinary classes, you should extend one of the Android test classes or JUnit classes, + because these provide the best testing features. +

+

+ If you run your tests with {@link android.test.InstrumentationTestRunner} + (or a related test runner), then it will run all the methods in each class. You can modify + this behavior by using the {@link junit.framework.TestSuite TestSuite} class. +

+ +

+ To create a test application, start with one of Android's test classes in the Java package + {@link android.test android.test}. These extend the JUnit + {@link junit.framework.TestCase TestCase} class. With a few exceptions, the Android test + classes also provide instrumentation for testing. +

+

+ For test classes that extend {@link junit.framework.TestCase TestCase}, you probably want to + override the setUp() and tearDown() methods: +

+ +

+ Another useful convention is to add the method testPreConditions() to your test + class. Use this method to test that the application under test is initialized correctly. If this + test fails, you know that that the initial conditions were in error. When this happens, further + test results are suspect, regardless of whether or not the tests succeeded. +

+

+ To learn more about creating test applications, see the topic Testing and Instrumentation, + which provides an overview of Android testing. If you prefer to follow a tutorial, + try the Activity Testing + tutorial, which leads you through the creation of tests for an actual Android application. +

+

Running Tests

+

+ If you are not developing in Eclipse with ADT, you need to run tests from the command line. + You can do this either with Ant or with the {@link android.app.ActivityManager ActivityManager} + command line interface. +

+

+ You can also run tests from the command line even if you are using Eclipse with ADT to develop + them. To do this, you need to create the proper files and directory structure in the test + project, using the android tool with the option create test-project. + This is described in the section Working with Test Projects. +

+

Quick build and run with Ant

+

+ You can use Ant to run all the tests in your test project, using the target + run-tests, which is created automatically when you create a test project with + the android tool. +

+

+ This target re-builds your main project and test project if necessary, installs the test + application to the current AVD or device, and then runs all the test classes in the test + application. The results are directed to STDOUT. +

+

+ You can update an existing test project to use this feature. To do this, use the + android tool with the update test-project option. This is described + in the section Updating a test project. +

Running tests on a device or emulator

+

+ When you run tests from the command line with the ActivityManager (am) + command-line tool, you get more options for choosing the tests to run than with any other + method. You can select individual test methods, filter tests according to their annotation, or + specify testing options. Since the test run is controlled entirely from a command line, you can + customize your testing with shell scripts in various ways. +

+

+ You run the am tool on an Android device or emulator using the + Android Debug Bridge + (adb) shell. When you do this, you use the ActivityManager + instrument option to run your test application using an Android test runner + (usually {@link android.test.InstrumentationTestRunner}). You set am + options with command-line flags. +

+

+ To run a test with am: +

+
    +
  1. + If necessary, re-build your main application and test application. +
    2. +
  2. + Install your test application and main application Android package files + (.apk files) to your current Android device or emulator
    3. +
  3. + At the command line, enter: +
    +$ adb shell am instrument -w <test_package_name>/<runner_class>
+
    +

    + where <test_package_name> is the Android package name of your test + application, and <runner_class> is the name of the Android test runner + class you are using. The Android package name is the value of the package + attribute of the manifest element in the manifest file + (AndroidManifest.xml) of your test application. The Android test runner + class is usually InstrumentationTestRunner. +

    +

    Your test results appear in STDOUT.

    +
    4. +
+

+ This operation starts an adb shell, then runs am instrument in it + with the specified parameters. This particular form of the command will run all of the tests + in your test application. You can control this behavior with flags that you pass to + am instrument. These flags are described in the next section. +

+

Using the Instrument Command

+

+ The general syntax of the am instrument command is: +

+
+    am instrument [flags] <test_package>/<runner_class>
+
+

+ The main input parameters to am instrument are described in the following table: +

+ + + + + + + + + + + + + + + + +
+ Parameter + + Value + + Description +
+ <test_package> + + The Android package name of the test application. + + The value of the package attribute of the manifest + element in the test application's manifest file. +
+ <runner_class> + + The class name of the instrumented test runner you are using. + + This is usually {@link android.test.InstrumentationTestRunner}. +
+

+The flags for am instrument are described in the following table: +

+ + + + + + + + + + + + + + + + + + + + + +
+ Flag + + Value + + Description +
+ -w + + (none) + + Forces am instrument to wait until the instrumentation terminates + before terminating itself. The net effect is to keep the shell open until the tests + have finished. This flag is not required, but if you do not use it, you will not + see the results of your tests. +
+ -r + + (none) + + Outputs results in raw format. Use this flag when you want to collect + performance measurements, so that they are not formatted as test results. This flag is + designed for use with the flag -e perf true (documented in the section + Instrument options). +
+ -e + + <test_options> + + Provides testing options , in the form of key-value pairs. The + am instrument tool passes these to the specified instrumentation class + via its onCreate() method. You can specify multiple occurrences of + -e <test_options. The keys and values are described in the next table. +

+ The only instrumentation class that understands these key-value pairs is + InstrumentationTestRunner (or a subclass). Using them with + any other class has no effect. +

+
+ +

Instrument options

+

+ The am instrument tool passes testing options to + InstrumentationTestRunner or a subclass in the form of key-value pairs, + using the -e flag, with this syntax: +

+
+    -e <key> <value>
+
+

+ Where applicable, a <key> may have multiple values separated by a comma (,). + For example, this invocation of InstrumentationTestRunner provides multiple + values for the package key: +

+$ adb shell am instrument -w -e package com.android.test.package1,com.android.test.package2 com.android.test/android.test.InstrumentationTestRunner
+
+

+ The following table describes the key-value pairs and their result. Please review the + Usage Notes following the table. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
KeyValueDescription
+ package + + <Java_package_name> + + The fully-qualified Java package name for one of the packages in the test + application. Any test case class that uses this package name is executed. Notice that this + is not an Android package name; a test application has a single Android package + name but may have several Java packages within it. +
class<class_name> + The fully-qualified Java class name for one of the test case classes. Only this test case + class is executed. +
<class_name>#method name + A fully-qualified test case class name, and one of its methods. Only this method is + executed. Note the hash mark (#) between the class name and the method name. +
functrue + Runs all test classes that extend {@link android.test.InstrumentationTestCase}. +
unittrue + Runs all test classes that do not extend either + {@link android.test.InstrumentationTestCase} or {@link android.test.PerformanceTestCase}. +
size[small | medium | large] + + Runs a test method annotated by size. The annotations are @SmallTest, + @MediumTest, and @LargeTest. +
perftrue + Runs all test classes that implement {@link android.test.PerformanceTestCase}. + When you use this option, also specify the -r flag for + am instrument, so that the output is kept in raw format and not + re-formatted as test results. +
debugtrue + Runs tests in debug mode. +
logtrue + Loads and logs all specified tests, but does not run them. The test + information appears in STDOUT. Use this to verify combinations of other filters + and test specifications. +
emmatrue + Runs an EMMA code coverage analysis and writes the output to /data//coverage.ec + on the device. To override the file location, use the coverageFile key that + is described in the following entry. +

+ Note: This option requires an EMMA-instrumented build of the test + application, which you can generate with the coverage target. +

+
coverageFile<filename> + Overrides the default location of the EMMA coverage file on the device. Specify this + value as a path and filename in UNIX format. The default filename is described in the + entry for the emma key. +
+-e Flag Usage Notes + +

Instrument examples

+

+Here are some examples of using am instrument to run tests. They are based on +the following structure:

+ +

Running the Entire Test Application

+

+ To run all of the test classes in the test application, enter: +

+
+$ adb shell am instrument -w com.android.demo.app.tests/android.test.InstrumentationTestRunner
+
+

Running All Tests in a Test Case Class

+

+ To run all of the tests in the class UnitTests, enter: +

+
+$ adb shell am instrument -w  \
+-e class com.android.demo.app.tests.UnitTests \
+com.android.demo.app.tests/android.test.InstrumentationTestRunner
+
+

+ am instrument gets the value of the -e flag, detects the + class keyword, and runs all the methods in the UnitTests class. +

+

Selecting a Subset of Tests

+

+ To run all of the tests in UnitTests, and the testCamera method in + FunctionTests, enter: +

+
+$ adb shell am instrument -w \
+-e class com.android.demo.app.tests.UnitTests,com.android.demo.app.tests.FunctionTests#testCamera \
+com.android.demo.app.tests/android.test.InstrumentationTestRunner
+
+

+ You can find more examples of the command in the documentation for + {@link android.test.InstrumentationTestRunner}. +

    Overview

    -

    -At the heart of the Android testing environment is an instrumentation framework that your test application uses to precisely control the application under test. With instrumentation, you can -set up mock system objects such as Contexts before the main application starts, control your application at various points of its lifecycle, send UI events to the application, and -examine the application's state during its execution. The instrumentation framework accomplishes this by running both the main application and the test application in the same process. -

    -

    - Your test application's manifest file links it to the application under test. The the <instrumentation> attribute in the manifest file points to the application under test - and also tells Android how to run the test application. This is described in more detail in the section Instrumentation Test Runner. -
