执行单个测试时使用Eclipse和JUNIT4的initializationError

我的测试类就是这个：

/** * 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 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 **/ } 

如果我执行测试套件我没有问题，但如果只突出其中一个并运行它我Unrooted Tests -> InitializationError

该类使用Parameterized 。

例外是：

 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.(JUnit4TestReference.java:33) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestMethodReference.(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) 

有什么我做错了吗？

你可以通过扩展参数化来覆盖org.junit.runners.ParentRunner＃filter来解决这个问题。

 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)); } } 

另一种方法是在Launch配置中更改方法名称，使其具有参数名称，如testAddSubscriberWithInternalPkIdCaseSensitive[0]
