The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\n\n\nabstract\n@interface\nJankTest\n`\n\n\n`\n\n\nimplements\n\n`[Annotation](https://developer.android.com/reference/java/lang/annotation/Annotation.html)`\n\n\n`\n\n|------------------------------------|\n| android.support.test.jank.JankTest |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nAnnotation used to configure a jank test method.\n\nSummary\n-------\n\n| ### Public methods ||\n|----------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| ` `[String](https://developer.android.com/reference/java/lang/String.html) | ` `[afterLoop](/reference/android/support/test/jank/JankTest#afterLoop())`() ` Alternate method to execute after each iteration Note: the annotated method must have same signature as [afterLoop()](/reference/android/support/test/jank/JankTestBase#afterLoop()) |\n| ` `[String](https://developer.android.com/reference/java/lang/String.html) | ` `[afterTest](/reference/android/support/test/jank/JankTest#afterTest())`() ` Alternate method to execute after all iterations have completed. |\n| ` `[String](https://developer.android.com/reference/java/lang/String.html) | ` `[beforeLoop](/reference/android/support/test/jank/JankTest#beforeLoop())`() ` Alternate method to execute before each iteration Note: the annotated method must have same signature as [beforeLoop()](/reference/android/support/test/jank/JankTestBase#beforeLoop()) |\n| ` `[String](https://developer.android.com/reference/java/lang/String.html) | ` `[beforeTest](/reference/android/support/test/jank/JankTest#beforeTest())`() ` Alternate method to execute before the test method Note: the annotated method must have same signature as [beforeTest()](/reference/android/support/test/jank/JankTestBase#beforeTest()) |\n| ` int` | ` `[defaultIterationCount](/reference/android/support/test/jank/JankTest#defaultIterationCount())`() ` Default iteration count to run if not specified by command line |\n| ` int` | ` `[expectedFrames](/reference/android/support/test/jank/JankTest#expectedFrames())`() ` The minimum number of frames expected |\n\n| ### Inherited methods |\n|-----------------------|---|\n| From interface ` `[java.lang.annotation.Annotation](https://developer.android.com/reference/java/lang/annotation/Annotation.html)` ` |---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------| | ` abstract `[Class](https://developer.android.com/reference/java/lang/Class.html)`\u003c?
