Example 1 with SessionTestRunner

use of org.eclipse.core.tests.session.SessionTestRunner in project eclipse.platform.runtime by eclipse.

the class MultipleRunsTest method testMultipleRuns.

public void testMultipleRuns() throws SetupManager.SetupException {
    // the test case to run multiple times

    test.setPluginId(CoreTest.PI_HARNESS);
    test.setTestRunner(new SessionTestRunner());
    // setup the command line to be passed to the multiple runs so it has the right system properties
    test.setSetup(SetupManager.getInstance().getDefaultSetup());
    test.getSetup().setSystemProperty("eclipse.perf.dbloc", System.getProperty("eclipse.perf.dbloc"));
    test.getSetup().setSystemProperty("eclipse.perf.config", System.getProperty("eclipse.perf.config"));
    // runs the test case several times - only to collect data, won't do any assertions
    TestResult result = new TestResult();
    for (int i = 0; i < 5; i++) {
        test.run(result);
        if (result.failureCount() > 0) {
            result.failures().nextElement().thrownException().printStackTrace();
            return;

            result.errors().nextElement().thrownException().printStackTrace();
            return;
        }
    }
    // create a performance meter whose scenario id matches the one used in the test case run
    // our convention: scenario IDs are <test case class name> + '.' + <test case method name>
    PerformanceMeter meter = Performance.getDefault().createPerformanceMeter(test.getTestClass() + '.' + test.getTestMethod());
    // finally do the assertion
    Performance.getDefault().assertPerformanceInRelativeBand(meter, Dimension.ELAPSED_PROCESS, -50, 5);
