    OutputVariable<?> gradientBranches = map.get(RuntimeVariable.Gradient_Branches.toString());
    Assert.assertNotNull(gradientBranches);
    Assert.assertEquals(4, gradientBranches.getValue());
}

Example 2 with EvoSuite

use of org.evosuite.EvoSuite in project evosuite by EvoSuite.

the class SearchStatisticsSystemTest method testHandlingOfNoThreads.

@Test
public void testHandlingOfNoThreads() {
    EvoSuite evosuite = new EvoSuite();
    String targetClass = NoThreads.class.getCanonicalName();
    Properties.TARGET_CLASS = targetClass;
    Properties.SANDBOX = true;
    Properties.OUTPUT_VARIABLES = "" + RuntimeVariable.Threads;
    String[] command = new String[] { "-generateSuite", "-class", targetClass };

    Assert.assertNotNull(map);
    OutputVariable<?> threads = map.get(RuntimeVariable.Threads.toString());
    Assert.assertNotNull(threads);
    Assert.assertEquals(1, threads.getValue());
}

Example 3 with EvoSuite

use of org.evosuite.EvoSuite in project evosuite by EvoSuite.

the class SearchStatisticsSystemTest method testHandlingOfMultiThreads.

// ignored due to problems of JVM8 crashing on MacOS, and anyway we do not really need to check for threads any more
@Ignore
@Test
public void testHandlingOfMultiThreads() {
    EvoSuite evosuite = new EvoSuite();
    String targetClass = MultiThreads.class.getCanonicalName();
    Properties.TARGET_CLASS = targetClass;
    Properties.SANDBOX = true;
    Properties.OUTPUT_VARIABLES = "" + RuntimeVariable.Threads;
    String[] command = new String[] { "-generateSuite", "-class", targetClass };
    evosuite.parseCommandLine(command);
    Map<String, OutputVariable<?>> map = DebugStatisticsBackend.getLatestWritten();
    Assert.assertNotNull(map);
    OutputVariable<?> threads = map.get(RuntimeVariable.Threads.toString());
    Assert.assertNotNull(threads);
    Assert.assertEquals(3, threads.getValue());
// TODO: This test currently fails because MSecurityManager does not set the number
// of threads correctly to avoid a JVM8 crash on MacOS:
// PermissionStatistics.getInstance().countThreads(Thread.currentThread().getThreadGroup().activeCount());
}

Example 4 with EvoSuite

use of org.evosuite.EvoSuite in project evosuite by EvoSuite.

the class FactoryTestSystemTest method setupCluster.

@Before
public void setupCluster() {
    EvoSuite evosuite = new EvoSuite();
    // Archive will remove test calls,
    // invalidating testTestCalls
    Properties.TEST_ARCHIVE = false;
    String targetClass = FactoryExample.class.getCanonicalName();
    Properties.TARGET_CLASS = targetClass;
    Properties.ASSERTIONS = false;
    String[] command = new String[] { "-generateSuite", "-class", targetClass };
    // Object result =
    evosuite.parseCommandLine(command);
// GeneticAlgorithm<?> ga = getGAFromResult(result);
// TestSuiteChromosome best = (TestSuiteChromosome) ga.getBestIndividual();
// System.out.println("EvolvedTestSuite:\n" + best);
}

Example 5 with EvoSuite

use of org.evosuite.EvoSuite in project evosuite by EvoSuite.

the class JUnitTestCarvedChromosomeFactorySystemTest method testDifficultClassWithWrongTestFails.

// EvoSuite may also cover it without seeding now.
@Ignore
@Test
public void testDifficultClassWithWrongTestFails() {
