PerformanceTestCase

android.test.PerformanceTestCase

Class Overview

More complex interface performance for test cases. If you want your test to be used as a performance test, you must implement this interface.

Summary

Nested Classes
interface PerformanceTestCase.Intermediates Callbacks for PerformanceTestCase . 
Public Methods
abstract boolean isPerformanceOnly ()
This method is used to determine what modes this test case can run in.
abstract int startPerformance ( PerformanceTestCase.Intermediates intermediates)
Set up to begin performance tests.

Public Methods

public abstract boolean isPerformanceOnly ()

Added in API level 1

This method is used to determine what modes this test case can run in.

Returns
  • true if this test case can only be run in performance mode.

public abstract int startPerformance ( PerformanceTestCase.Intermediates intermediates)

Added in API level 1

Set up to begin performance tests. The 'intermediates' is a communication channel to send back intermediate performance numbers -- if you use it, you will probably want to ensure your test is only executed once by returning 1. Otherwise, return 0 to allow the test harness to decide the number of iterations.

If you return a non-zero iteration count, you should call intermediates.startTiming and intermediates.endTiming to report the duration of the test whose performance should actually be measured.

Parameters
intermediates Callback for sending intermediate results.
Returns
  • int Maximum number of iterations to run, or 0 to let the caller decide.
