流程从 Controller.callMethod() 开始。它调用一个抛出 MyException 的方法。 MyException 由 Controller 中编写的异常处理程序处理:
public class Controller{
public Response callMethod() throws MyException {
ClassToTest classToTest = new ClassToTest();
return(classToTest.method());
}
@ExceptionHandler(MyException.class)
public @ResponseBody
Response myException(HttpServletRequest req,
HttpServletResponse res, MyException myException) {
Response response = new Response();
response.setResponseCode(myException.getErrorCode());
return response;
}
}
public class ClassToTest {
public Response method() throws MyException {
Response response = anotherMethod();
return response;
}
public String anotherMethod(){
if(//something)
throw new MyException(Constant.ERROR_CODE); // I need to test this line
else
return //some response
}
}
}
这是我的测试类:
public class Test {
@Test
public void testMethod(){
try{
ClassToTest classtotest = new ClassToTest();
Response response = classtotest.method(); //I want to get response after getting MyException (Response created by the myException ExceptionHandler)
assertEquals("SUCCESS", response.getResponseCode);
} catch(Exception e){
//After getting MyException the control comes here & thats the problem. assertEquals never get executed.
} }
}
当行 Response response = classtotest.method();正在执行然后控件将进入测试类的缓存 block 。我想获取使用 myException ExceptionHandler 创建的 Response 并测试其响应代码。谁能告诉我如何使用 Mockito 做到这一点?
最佳答案
您可以使用 expected属性,但是如果您需要测试某些特定消息,请尝试这样的操作:
@Test
public void shouldThrowSomeException() {
String errorMessage = "";
try {
Result result = service.method("argument");
} catch (SomeException e) {
errorMessage = e.getMessage();
}
assertTrue(errorMessage.trim().equals(
"ExpectedMessage"));
}
