Interface IDataProviderInterceptor

All Superinterfaces:

ITestNGListener

public interface IDataProviderInterceptor
extends ITestNGListener

This interface helps define an interceptor for data providers. Implementations of this TestNG listener can be wired in via the @Listeners annotation or via the listeners tag in the suite file or via a Service Provider Interface mechanism. The implementation would be able to alter the actual set of data using which a test method would be iterated upon.

Method Detail

intercept

java.util.Iterator<java.lang.Object[]> intercept(java.util.Iterator<java.lang.Object[]> original,
                                                 IDataProviderMethod dataProviderMethod,
                                                 ITestNGMethod method,
                                                 ITestContext iTestContext)

Parameters:

original - - The original data set as produced by a particular data provider.

dataProviderMethod - - The IDataProviderMethod method object which represents the data provider that was invoked.

method - - The ITestNGMethod method object which represents the test method that will receive the parameters.

iTestContext - - The ITestContext object that represents the current test context.

Returns:

- The altered data set that would be used by TestNG to run the test method.
