您可以解决问题的办法是覆盖org.junit.runners.ParentRunner#filter by扩展参数化
public class IDECompatibleParameterized extends参数化{
public void filter(Filter filter)throws NoTestsRemainException {
super.filter(new FilterDecorator(filter));
}
/ **
*在参数化测试的情况下运行单次测试会导致问题,如
* http://youtrack.jetbrains.com/issue中所述/ IDEA-65966
*
*作为解决方法,我们包装原始过滤器,然后传递一个包装描述
*,它删除参数部分(请参阅deparametrizedName)
* /
private static class FilterDecorator extends Filter {
private final Filter delegate;
private FilterDecorator(Filter delegate){
this.delegate = delegate;
}
@Override
public boolean shouldRun(描述描述){
return delegate.shouldRun(wrap(description));
}
@Override
public String describe(){
return delegate.describe();
}
}
private static描述wrap(描述描述){
String name = description.getDisplayName();
String fixedName = deparametrizedName(name);
描述clonedDescription =
Description.createSuiteDescription(fixedName,description.getAnnotations()。toArray(new Annotation [0]));
for(Description child:description.getChildren()){
clonedDescription.addChild(wrap(child));
}
返回克隆描述;
}
private static String deparametrizedName(String name){
//每个参数被命名为[0],[1] etc
if(name.startsWith ([)){
return name;
}
//将methodName [index](className)转换为
// 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中更改方法名称配置参数名称如 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

Is there something I'm doing wrong?
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]
