InstrumentationTestRunner

public class InstrumentationTestRunner
extends Instrumentation implements TestSuiteProvider

java.lang.Object
   ↳ android.app.Instrumentation
     ↳ android.test.InstrumentationTestRunner
Known Direct Subclasses


This class was deprecated in API level 24.
Use AndroidJUnitRunner instead. New tests should be written using the Android Testing Support Library.

An Instrumentation that runs various types of TestCases against an Android package (application).

Developer Guides

For more information about application testing, read the Testing developer guide.

Typical Usage

  1. Write TestCases that perform unit, functional, or performance tests against the classes in your package. Typically these are subclassed from:
  2. Set the android:targetPackage attribute of the <instrumentation> element in the test package's manifest. You should set the attribute value to the package name of the target application under test.
  3. Run the instrumentation using "adb shell am instrument -w", with no optional arguments, to run all tests (except performance tests).
  4. Run the instrumentation using "adb shell am instrument -w", with the argument '-e func true' to run all functional tests. These are tests that derive from InstrumentationTestCase.
  5. Run the instrumentation using "adb shell am instrument -w", with the argument '-e unit true' to run all unit tests. These are tests that do notderive from InstrumentationTestCase (and are not performance tests).
  6. Run the instrumentation using "adb shell am instrument -w", with the argument '-e class' set to run an individual TestCase.

Running all tests: adb shell am instrument -w com.android.foo/android.test.InstrumentationTestRunner

Running all small tests: adb shell am instrument -w -e size small com.android.foo/android.test.InstrumentationTestRunner

Running all medium tests: adb shell am instrument -w -e size medium com.android.foo/android.test.InstrumentationTestRunner

Running all large tests: adb shell am instrument -w -e size large com.android.foo/android.test.InstrumentationTestRunner

Filter test run to tests with given annotation: adb shell am instrument -w -e annotation com.android.foo.MyAnnotation com.android.foo/android.test.InstrumentationTestRunner

If used with other options, the resulting test run will contain the union of the two options. e.g. "-e size large -e annotation com.android.foo.MyAnnotation" will run only tests with both the LargeTest and "com.android.foo.MyAnnotation" annotations.

Filter test run to tests without given annotation: adb shell am instrument -w -e notAnnotation com.android.foo.MyAnnotation com.android.foo/android.test.InstrumentationTestRunner

Running a single testcase: adb shell am instrument -w -e class com.android.foo.FooTest com.android.foo/android.test.InstrumentationTestRunner

Running a single test: adb shell am instrument -w -e class com.android.foo.FooTest#testFoo com.android.foo/android.test.InstrumentationTestRunner

Running multiple tests: adb shell am instrument -w -e class com.android.foo.FooTest,com.android.foo.TooTest com.android.foo/android.test.InstrumentationTestRunner

Running all tests in a java package: adb shell am instrument -w -e package com.android.foo.subpkg com.android.foo/android.test.InstrumentationTestRunner

Including performance tests: adb shell am instrument -w -e perf true com.android.foo/android.test.InstrumentationTestRunner

To debug your tests, set a break point in your code and pass: -e debug true

To run in 'log only' mode -e log true This option will load and iterate through all test classes and methods, but will bypass actual test execution. Useful for quickly obtaining info on the tests to be executed by an instrumentation command.

To generate EMMA code coverage: -e coverage true Note: this requires an emma instrumented build. By default, the code coverage results file will be saved in a /data//coverage.ec file, unless overridden by coverageFile flag (see below)

To specify EMMA code coverage results file path: -e coverageFile /sdcard/myFile.ec
in addition to the other arguments.

onCreate

Added in API level 1
void onCreate (Bundle arguments)

Called when the instrumentation is starting, before any application code has been loaded. Usually this will be implemented to simply call start() to begin the instrumentation thread, which will then continue execution in onStart().

If you do not need your own thread -- that is you are writing your instrumentation to be completely asynchronous (returning to the event loop so that the application can run), you can simply begin your instrumentation here, for example call startActivity(Intent) to begin the appropriate first activity of the application.

Parameters
arguments Bundle: Any additional arguments that were supplied when the instrumentation was started.

onStart

Added in API level 1
void onStart ()

Method where the instrumentation thread enters execution. This allows you to run your instrumentation code in a separate thread than the application, so that it can perform blocking operation such as sendKeySync(KeyEvent) or startActivitySync(Intent).

You will typically want to call finish() when this function is done, to end your instrumentation.

Protected methods

getAndroidTestRunner

Added in API level 1
AndroidTestRunner getAndroidTestRunner ()

Returns
AndroidTestRunner
