Class Invoker

java.lang.Object

org.testng.internal.Invoker

All Implemented Interfaces:

IInvoker

public class Invoker
extends java.lang.Object
implements IInvoker

This class is responsible for invoking methods: - test methods - configuration methods - possibly in a separate thread and then for notifying the result listeners.

Method Detail

getConfigInvoker

public ConfigInvoker getConfigInvoker()

Specified by:

getConfigInvoker in interface IInvoker

getTestInvoker

public TestInvoker getTestInvoker()

Specified by:

getTestInvoker in interface IInvoker

invokeConfigurations

public void invokeConfigurations(IClass testClass,
                                 ITestNGMethod[] allMethods,
                                 XmlSuite suite,
                                 java.util.Map<java.lang.String,java.lang.String> params,
                                 java.lang.Object[] parameterValues,
                                 java.lang.Object instance)

Invoke configuration methods if they belong to the same TestClass passed in parameter..

TODO: Calculate ahead of time which methods should be invoked for each class. Might speed things up for users who invoke the same test class with different parameters in the same suite run.

If instance is non-null, the configuration will be run on it. If it is null, the configuration methods will be run on all the instances retrieved from the ITestClass.

Specified by:

invokeConfigurations in interface IInvoker

Parameters:

testClass - the class whose configuration methods must be run

invokeTestMethods

public java.util.List<ITestResult> invokeTestMethods(ITestNGMethod testMethod,
                                                     java.util.Map<java.lang.String,java.lang.String> testParameters,
                                                     ConfigurationGroupMethods groupMethods,
                                                     java.lang.Object instance,
                                                     ITestContext testContext)

Invoke all the test methods. Note the plural: the method passed in parameter might be invoked several times if the test class it belongs to has more than one instance (i.e., if an @Factory method has been declared somewhere that returns several instances of this TestClass). If no @Factory method was specified, testMethod will only be invoked once.

Note that this method also takes care of invoking the beforeTestMethod and afterTestMethod, if any.

Note (alex): this method can be refactored to use a SingleTestMethodWorker that directly invokes ITestInvoker.invokeTestMethod(TestMethodArguments, XmlSuite, FailureContext) and this would simplify the implementation (see how DataTestMethodWorker is used)

Specified by:

invokeTestMethods in interface IInvoker

Returns:

a list containing the results of the test methods invocations

log

static void log(int level,
                java.lang.String s)
