Class JUnitTestManager

java.lang.Object
  edu.rice.cs.drjava.model.junit.JUnitTestManager

public class JUnitTestManager
extends Object

Runs in the InterpreterJVM. Runs tests given a classname and formats the results into a (serializable) array of JUnitError that can be passed back to the MainJVM.

Field Detail

_log

protected static final Log _log

_jmc

private final JUnitModelCallback _jmc

The interface to the master JVM via RMI.

_loaderFactory

private final Lambda<ClassLoader,ClassLoader> _loaderFactory

A factory producing a ClassLoader for tests with the given parent

_testRunner

private JUnitTestRunner _testRunner

The current testRunner; initially null. Each test suite requires a new runner.

_suite

private TestSuite _suite

The accumulated test suite; null if no test is pending.

_testClassNames

private List<String> _testClassNames

The accumulated list of names of TestCase classes; null if no test is pending.

_testFiles

private List<File> _testFiles

The list of files corresponding to testClassNames; null if no test is pending.

Constructor Detail

JUnitTestManager

public JUnitTestManager(JUnitModelCallback jmc,
                        Lambda<ClassLoader,ClassLoader> loaderFactory)

Standard constructor

Method Detail

findTestClasses

public List<String> findTestClasses(List<String> classNames,
                                    List<File> files)

Find the test classes among the given classNames and accumulate them in TestSuite for junit. Returns null if a test suite is already pending.

Parameters:

classNames - the class names that are test class candidates

files - the files corresponding to classNames

runTestSuite

public boolean runTestSuite()

Runs the pending test suite set up by the preceding call to findTestClasses. Runs in a single auxiliary thread, so no need for explicit synchronization.

Returns:

false if no test suite (even an empty one) has been set up

_reset

private void _reset()

_isJUnitTest

private boolean _isJUnitTest(Class<?> c)

Determines if the given class is a junit Test.

Parameters:

c - the class to check

Returns:

true iff the given class is an instance of junit.framework.Test

_makeJUnitError

private JUnitError _makeJUnitError(TestFailure failure,
                                   List<String> classNames,
                                   boolean isError,
                                   List<File> files)

Constructs a new JUnitError from a TestFailure

Parameters:

failure - A given TestFailure

classNames - The classes that were used for this test suite

isError - The passed TestFailure may signify either an error or a failure

files - The files that were used for this test suite

Returns:

JUnitError

_lineNumber

private int _lineNumber(String sw,
                        String classname)

Parses the line number out of the stack trace in the given class name.

makeRunner

private JUnitTestRunner makeRunner()

Make a fresh JUnitTestRunner with its own class loader instance.
