Class AbstractTestSuiteChunkerImpl<T>

java.lang.Object

org.powermock.tests.utils.impl.AbstractCommonTestSuiteChunkerImpl

org.powermock.tests.utils.impl.AbstractTestSuiteChunkerImpl<T>

All Implemented Interfaces:

RunnerTestSuiteChunker, TestSuiteChunker

public abstract class AbstractTestSuiteChunkerImpl<T>
extends AbstractCommonTestSuiteChunkerImpl
implements RunnerTestSuiteChunker

Abstract base class for test suite chunking, i.e. a suite is chunked into several smaller pieces which are ran with different classloaders. A chunk is defined by the PrepareForTest annotation and whichever test-method annotation the actual implementation-class specifies by overriding the method AbstractCommonTestSuiteChunkerImpl.testMethodAnnotation(). This to make sure that you can byte-code manipulate classes in tests without impacting on other tests.

getInternalTestIndex

public int getInternalTestIndex(int originalTestIndex)

Get the internal test index for a junit runner delegate based on the "real" original test index. For example, the test may need to run a single test, for example the test with index 3. However since PowerMock may have chunked the test suite to use many classloaders and junit delegators the index (3) must be mapped to an internal representation for the specific junit runner delegate. This is what this method does. I.e. it will iterate through all junit runner delegates and see if they contain the test with index 3, in the internal index of this test delegator is returned.

Parameters:

originalTestIndex - The original test index as seen by the test runner.

Returns:

The internal test index as seen by PowerMock or -1 if no index was found.

getDelegatorIndex

public int getDelegatorIndex(int testIndex)

Get the junit runner delegate that handles the test at index testIndex. Throws a RuntimeException if a delegator is not found for the specific test index.

Parameters:

testIndex - The test index that a delegator should hold.

Returns:

The index for of the junit runner delegate as seen by JTestRack.
