JankTestBase

This package is part of the Android support library which is no longer maintained. The support library has been superseded by AndroidX which is part of Jetpack. We recommend using the AndroidX libraries in all new projects. You should also consider migrating existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library class mappings.

---

Base test class for measuring Jank. This test class automatically monitors jank while executing each test method. Each test method is executed several times in a loop, according to the 'iterations' command line parameter. To perform additional setup / tear down steps for each iteration, subclasses can optionally override beforeLoop() and afterLoop() methods. Test methods must be configured with the JankTest annotation. At minimum, the type of jank to measure and the number of expected frames must be specified.

beforeTest

void beforeTest ()

Called once before executing a test method.

Throws
Exception

getCurrentIteration

int getCurrentIteration ()

Return the index of the currently executing iteration.

Returns
int

Protected methods

getArguments

Bundle getArguments ()

Returns a Bundle containing the command line parameters.

Returns
Bundle
