Performance Regressions
You can extend your test class from PHPUnit2_Extensions_ PerformanceTestCase
to test whether the execution of a function or a method call, for instance, exceeds a specified time limit.
Example 8 shows how to subclass PHPUnit2_Extensions_ PerformanceTestCase
and use its setMaxRunningTime( )
method to set the maximum running time for the test. If the test is not executed within this time limit, it will be counted as a failure.
Example 8. Using PHPUnit2_Extensions_PerformanceTestCase
<?php require_once 'PHPUnit2/Extensions/PerformanceTestCase.php'; class PerformanceTest extends PHPUnit2_Extensions_ PerformanceTestCase { public function testPerformance( ) { $this->setMaxRunningTime(2); sleep(1); } } ?>
Table 2 shows the external protocol implemented by PHPUnit2_Extensions_PerformanceTestCase
.
