All Implemented Interfaces:

TestSuiteChunker

public abstract class AbstractTestSuiteChunkerImpl<T>
extends Object
implements TestSuiteChunker

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. This to make sure that you can byte-code manipulate classes in tests without impacting on other tests.

                                        String[] packagesToIgnore)

Description copied from interface: TestSuiteChunker

Create a new class loader and load classes from this classloader.

Specified by:

createNewClassloader in interface TestSuiteChunker

Parameters:

testClass - TODO

classesToLoadByMockClassloader - An array of the fully qualified name of the classes to modify.

packagesToIgnore - Packages to ignore.

public void createTestDelegators(Class<?> testClass,
                                 List<TestChunk> chunks)
                          throws Exception

Create the test delegators needed for a whole class.

Specified by:

createTestDelegators in interface TestSuiteChunker

Throws:

Exception

createDelegatorFromClassloader

protected abstract T createDelegatorFromClassloader(ClassLoader classLoader,
                                                    Class<?> testClass,
                                                    List<Method> methodsToTest)
                                             throws Exception

Throws:

getChunkSize

public int getChunkSize()

Description copied from interface: TestSuiteChunker

Get the number of chunks defined in this suite.

Specified by:

getChunkSize in interface TestSuiteChunker

Returns:

The number of chunks defined in the correct suite.

getTestChunks

public List<TestChunk> getTestChunks()

Description copied from interface: TestSuiteChunker

Get all chunk entries.

Specified by:

getTestChunks in interface TestSuiteChunker

Returns:

An set of entries that contains a list of methods contained in the chunk and the class loader that loaded these methods.

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.

getTestChunksEntries

public List<TestChunk> getTestChunksEntries(Class<?> testClass)

Get all chunk entries for a specific class.

Specified by:

getTestChunksEntries in interface TestSuiteChunker

Parameters:

testClass - The class whose chunk entries to get.

Returns:

An set of entries that contains a list of methods contained in the chunk for the specific test class and the class loader that loaded these methods.

getTestClasses

public Class<?>[] getTestClasses()

hasMockPolicyProvidedClasses

protected boolean hasMockPolicyProvidedClasses(Class<?> testClass)

Returns:

true if there are some mock policies that contributes with classes that should be loaded by the mock classloader, false otherwise.
