Method Details

getNotifier

public ITestResultNotifier getNotifier()

Specified by:

getNotifier in interface ITestInvoker

invokeTestMethods

public List<ITestResult> invokeTestMethods(ITestNGMethod testMethod,
 ConfigurationGroupMethods groupMethods,
 Object instance,
 ITestContext context)

Specified by:

invokeTestMethods in interface ITestInvoker

invokeTestMethod

public ITestResult invokeTestMethod(TestMethodArguments arguments,
 XmlSuite suite,
 ITestInvoker.FailureContext failureContext)

invokeTestMethods() eventually converge here to invoke a single @Test method.

This method is responsible for actually invoking the method. It decides if the invocation must be done:

• through an IHookable
• directly (through reflection)
• in a separate thread (in case it needs to timeout)

This method is also responsible for invoking @BeforeGroup, @BeforeMethod, @AfterMethod, @AfterGroup if it is the case for the passed in @Test method.

Specified by:

invokeTestMethod in interface ITestInvoker

retryFailed

public ITestInvoker.FailureContext retryFailed(TestMethodArguments arguments,
 List<ITestResult> result,
 int failureCount,
 ITestContext testContext)

Specified by:

retryFailed in interface ITestInvoker

runTestResultListener

public void runTestResultListener(ITestResult tr)

Specified by:

runTestResultListener in interface ITestInvoker

dataProviderListeners

private Collection<IDataProviderListener> dataProviderListeners()

buildDataProviderHolder

private DataProviderHolder buildDataProviderHolder()

checkDependencies

private String checkDependencies(ITestNGMethod testMethod)

Checks to see of the test method has certain dependencies that prevents TestNG from executing it

Parameters:

testMethod - test method being checked for

Returns:

error message or null if dependencies have been run successfully

runWorkers

private List<ITestResult> runWorkers(ITestNGMethod testMethod,
 List<IWorker<ITestNGMethod>> workers,
 int threadPoolSize,
 ConfigurationGroupMethods groupMethods,
 XmlSuite suite,
 Map<String,String> parameters)

To reduce thread contention and also to correctly handle thread-confinement this method invokes the @BeforeGroups and @AfterGroups corresponding to the current @Test method.

failuresPresentInUpstreamDependency

private boolean failuresPresentInUpstreamDependency(ITestNGMethod testMethod,
 ITestNGMethod[] methods)

keepSameInstances

private Set<ITestResult> keepSameInstances(ITestNGMethod method,
 Set<ITestResult> results)

Returns:

the test results that apply to one of the instances of the testMethod.

invokePooledTestMethods

private List<ITestResult> invokePooledTestMethods(ITestNGMethod testMethod,
 XmlSuite suite,
 Map<String,String> parameters,
 ConfigurationGroupMethods groupMethods,
 ITestContext testContext)

Invokes a method that has a specified threadPoolSize.

collectResults

private void collectResults(ITestNGMethod testMethod,
 ITestResult result)

invokeListenersForSkippedTestResult

public void invokeListenersForSkippedTestResult(ITestResult r,
 IInvokedMethod invokedMethod)

Specified by:

invokeListenersForSkippedTestResult in interface ITestInvoker

setTestStatus

private static void setTestStatus(ITestResult result,
 int status)

handleInvocationResults

private void handleInvocationResults(ITestNGMethod testMethod,
 ITestResult testResult,
 ITestInvoker.FailureContext failure,
 TestInvoker.StatusHolder holder,

public ITestResult registerSkippedTestResult(ITestNGMethod testMethod,
 long start,
 Throwable throwable,
 ITestResult source)

Specified by:

registerSkippedTestResult in interface ITestInvoker

considerExceptions

private TestInvoker.StatusHolder considerExceptions(ITestNGMethod tm,
 ITestResult testresult,
 ExpectedExceptionsHolder exceptionsHolder,
 ITestInvoker.FailureContext failure)

computeTestStatusComparingTestResultAndStatusHolder

private static int computeTestStatusComparingTestResultAndStatusHolder(ITestResult testResult,
