How do you assert that a certain exception is thrown in JUnit 4 tests?32个
我正在使用JUnit 4.11.
我正在使用JUnit 4.11.
Eclipse版本：Luna Service Release 2(4.4.2)
我需要做异常测试.代码可能是这样的：
// src code
public void myMethod throws MyException {
...
throw new MyException(msg);
...
}
// test code
@Test (expected = MyException.class)
public void testMyMethod() {
try {
myMethod();
fail();
} catch (MyException e) {
assertEquals(expectedStr,e.getMessage());
}
}
但测试总是失败,我错在哪里？
