# VisibleForTesting Summary: [Constants](https://developer.android.com/reference/android/support/annotation/VisibleForTesting#constants) \| [Methods](https://developer.android.com/reference/android/support/annotation/VisibleForTesting#pubmethods) \| [Inherited Methods](https://developer.android.com/reference/android/support/annotation/VisibleForTesting#inhmethods) \| [\[Expand All\]](https://developer.android.com/reference/android/support/annotation/VisibleForTesting#) # VisibleForTesting | This package is part of the Android [support library](https://developer.android.com/topic/libraries/support-library) which is no longer maintained. The support library has been superseded by [AndroidX](https://developer.android.com/jetpack/androidx) which is part of [Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](https://developer.android.com/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class | mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public abstract @interface VisibleForTesting ` ` implements Annotation ` |----------------------------------------------| | android.support.annotation.VisibleForTesting |
*** ** * ** *** Denotes that the class, method or field has its visibility relaxed, so that it is more widely visible than otherwise necessary to make code testable. You can optionally specify what the visibility **should** have been if not for testing; this allows tools to catch unintended access from within production code. Example: @VisibleForTesting(otherwise = VisibleForTesting.PROTECTED) public String printDiagnostics() { ... } If not specified, the intended visibility is assumed to be private.

Constant Value: 5 (0x00000005) ### PACKAGE_PRIVATE ``` int PACKAGE_PRIVATE ``` The annotated element would have "package private" visibility
Constant Value: 3 (0x00000003) ### PRIVATE ``` int PRIVATE ``` The annotated element would have "private" visibility
Constant Value: 2 (0x00000002) ### PROTECTED ``` int PROTECTED ``` The annotated element would have "protected" visibility
Constant Value: 4 (0x00000004) ## Public methods ### otherwise ``` int otherwise () ``` The visibility the annotated element would have if it did not need to be made visible for testing.
