initializationError with Eclipse and JUNIT4 when executing a single test

You can possibly workaround the problem by overriding the org.junit.runners.ParentRunner#filter by extending the Parameterized
public class IDECompatibleParameterized extends Parameterized {
public void filter(Filter filter) throws NoTestsRemainException {
super.filter(new FilterDecorator(filter));
}
/**
* Running single test in case of parameterized test causes issue as explained in
* http://youtrack.jetbrains.com/issue/IDEA-65966
*
* As a workaround we wrap the original filter and then pass it a wrapped description
* which removes the parameter part (See deparametrizedName)
*/
private static class FilterDecorator extends Filter {
private final Filter delegate;
private FilterDecorator(Filter delegate) {
this.delegate = delegate;
}
@Override
public boolean shouldRun(Description description) {
return delegate.shouldRun(wrap(description));
}
@Override
public String describe() {
return delegate.describe();
}
}
private static Description wrap(Description description) {
String name = description.getDisplayName();
String fixedName = deparametrizedName(name);
Description clonedDescription =
Description.createSuiteDescription(fixedName,description.getAnnotations().toArray(new Annotation[0]));
for(Description child : description.getChildren()){
clonedDescription.addChild(wrap(child));
}
return clonedDescription;
}
private static String deparametrizedName(String name) {
//Each parameter is named as [0], [1] etc
if(name.startsWith("[")){
return name;
}
//Convert methodName[index](className) to
//methodName(className)
int indexOfOpenBracket = name.indexOf('[');
int indexOfCloseBracket = name.indexOf(']')+1;
return name.substring(0,indexOfOpenBracket).concat(name.substring(indexOfCloseBracket));
}
}
Another way would be to change the method name in Launch configuration to have the parameter name like testAddSubscriberWithInternalPkIdCaseSensitive[0]

My test class is this one:
/** * The Class TestAddSubscriber. */ @RunWith(LabelledParameterized.class) public class TestAddSubscriber extends AbstractTestSubscriber { /** * Instantiates a new test add subscriber. * * @param label * the label * @param apiKey * the api key * @param userKey * the user key * @param customerId * the customer id */ public TestAddSubscriber(String label, String apiKey, String userKey, int customerId) { super(label, apiKey, userKey, customerId); } /** * @see com.contactlab.api.test.AbstractTest#setUp() */ @Override @Before public void setUp() throws Exception { super.setUp(); } /** * @see com.contactlab.api.test.AbstractTest#tearDown() */ @Override @After public void tearDown() throws Exception { super.tearDown(); } /** * Generated data. * * @return the collection */ @Parameters public static Collection<Object[]> generatedData() { return DataProvider.generatedCorrectSubscriberData(); } /** * Test add subscriber with internal pk id case sensitive. * * @outcome: success * @expected: success * @obtained: success */ @Test public void testAddSubscriberWithInternalPkIdCaseSensitive() { /** this is the test **/ } /** * other tests **/ }
If I execute the Test Suite I'm not having problem but If highlight only one of them and run it I'm having
Unrooted Tests -> InitializationError
The class uses
Parameterized
.The exception is:
TestAddSubscriber.testAddSubscriberWithInternalPkIdCaseSensitive Unrooted Tests initializationError(org.junit.runner.manipulation.Filter) java.lang.Exception: No tests found matching Method testAddSubscriberWithInternalPkIdCaseSensitive(com.contactlab.api.test.subscriber.TestAddSubscriber) from org.junit.internal.requests.ClassRequest@18872380 at org.junit.internal.requests.FilterRequest.getRunner(FilterRequest.java:37) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.<init>(JUnit4TestReference.java:33) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestMethodReference.<init>(JUnit4TestMethodReference.java:25) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:54) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:452) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)
Is there something I'm doing wrong?
