Question

我正在运行此代码，并意识到getAllParameters()方法由于某种原因运行了两次。因为静态字段enumMap在该方法之外被初始化，所以它会被填充两次，这会导致重复的元素并且无法运行我的测试。

我认为在方法中初始化enumMap可以解决问题，因为当方法第二次运行时，地图会重置。

即使这解决了问题，我想知道为什么在运行Maven Test时会发生这种情况？我玩了很多参数，认为这可能会影响方法运行的次数，但它似乎只运行了两次。

@RunWith(Parameterized.class)
public class MyTest {

    private static Map<String, List<Class<? extends LocalizedJsonEnum>>> enumMap = new HashMap<>();

    @Parameter
    @SuppressWarnings({"WeakerAccess", "unused"})
    public Class<? extends LocalizedJsonEnum> currentEnum;
    @Parameter(value = 1)
    @SuppressWarnings({"WeakerAccess", "unused"})
    public  String currentClassName;

    /**
     * Generate a list of all the errors to run our test against.
     *
     * @return the list
     */
    @Parameters(name = "{1}.class")
    public static Collection<Object[]> getAllParameters() throws Exception {
        Collection<Object[]> parameters = new LinkedList<>();
        Reflections reflections = new Reflections("com.class.path");
        Set<Class<? extends LocalizedJsonEnum>> JsonEnums = reflections.getSubTypesOf(LocalizedJsonEnum.class);

        //workaround: initialize here
        //enumMap = new HashMap<>();

        //some code that inserts elements into the enumMap and parameters 
        return parameters;
    }


@Test
public void testEnumIdentifierIsNotDuplicated() throws Exception {

    String enumId;
    if (currentEnum.isAnnotationPresent(Identifier.class)) {
        enumId = currentEnum.getAnnotation(Identifier.class).value();
    } else {
        enumId = currentEnum.getSimpleName();
    }
    List<Class<? extends LocalizedJsonEnum>> enumList = enumMap.get(enumId);

    if (enumList.size() > 1) {

        StringBuilder sb = new StringBuilder("Enum or identifier [" + enumId + "] has been duplicated in the following classes:\n");
        for (int listIndex = 0; listIndex < enumList.size(); listIndex++) {
            Class<? extends LocalizedJsonEnum> enumDuplicate = enumList.get(listIndex);
            sb.append("   [").append(listIndex).append("] Enum Class:[").append(enumDuplicate.getName()).append("]\n");
        }
        fail(sb.toString());
    }
}

参数化方法运行两次
