我创建了一个自定义的 JUnit 4 运行器(扩展 BlockJUnit4Runner),其目的是运行其他测试在运行这些测试之前有效所必需的测试。例如,如果您正在测试某个文件 IO,则读/写测试将需要打开/关闭测试才能正常工作。
这可以使用任意数量的要求正确运行测试,并且对于不需要其他任何东西的测试返回正常报告,但是当我运行一个确实需要另一个测试时,我得到“完成:1 of 2”,并且事件日志说“测试通过:1 通过”。即使要求的测试(第二个运行)失败也是如此。

protected void runChild(FrameworkMethod method, RunNotifier notifier) {
if (!alreadyRunMethods.containsKey(method.getName())) {
boolean requiredMethodsPassed = true;
for (Annotation anno : method.getAnnotations()) {
if (anno instanceof Requires) {
requiredMethodsPassed = runRequiredMethods((Requires) anno, notifier, method);
break;
}
}
if (requiredMethodsPassed) {
super.runChild(method, notifier);
}else{
notifier.fireTestAssumptionFailed(new Failure(describeChild(method), new AssumptionViolatedException("Required methods failed.")));
}
}
}
private boolean runRequiredMethods(Requires req, RunNotifier notifier, FrameworkMethod parentMethod) {
boolean passed = true;
for (String methodName : req.value()) {
FrameworkMethod method = methodByName.get(methodName);
if (method == null) {
throw new RuntimeException(String.format("Required test method '%s' on test method '%s' does not exist.", methodName, parentMethod.getName()));
}
runChild(method, notifier);
Boolean methodPassed = alreadyRunMethods.get(method.getName());
methodPassed = methodPassed == null ? false : methodPassed;
passed &= methodPassed;
}
return passed;
}
