Interface PerformanceTestCase

All Known Implementing Classes:

PerformanceTestBase

public interface PerformanceTestCase

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

Nested Class Summary

static interface

PerformanceTestCase.Intermediates Callbacks for PerformanceTestCase.

Method Summary

boolean	isPerformanceOnly() This method is used to determine what modes this test case can run in.
int	startPerformance(PerformanceTestCase.Intermediates intermediates) Set up to begin performance tests.

Method Detail

startPerformance

int startPerformance(PerformanceTestCase.Intermediates intermediates)

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.

isPerformanceOnly

boolean isPerformanceOnly()

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.
