测试功能未捕获预期异常作为需求值。它会引发异常,就像一个错误。
我尝试制作
@Rule
ExpectedException thrown = ExpectedException.none();
@Test(expected = UnsupportedOperationException.class)
public void testNotAddingDifferentCurrency(){
Money money1 = new Money("4.43", Locale.GERMANY);
Money money2 = new Money("1.436", Locale.US);
money1.add(money2);
thrown.expect(InvalidBarcodeException.class);
}
和
@Test(expected = UnsupportedOperationException.class)
public void testNotAddingDifferentCurrency() throws UnsupportedOperationException{
Money money1 = new Money("4.43", Locale.GERMANY);
Money money2 = new Money("1.436", Locale.US);
money1.add(money2);
}
但是它仍然会给出响应:

金钱类主体:
public Money add(Money other) {
if (!compatibleCurrency(other)) {
throw new UnsupportedOperationException();
}
return new Money(amount.add(other.amount), currency);
}
@Override
public String toString() {
return decimalFormat.format(amount);
}
@Override
public boolean equals(Object o) {
Money money = (Money) o;
if (!amount.equals(money.amount)) return false;
if (!currency.equals(money.currency)) return false;
if (!decimalFormat.equals(money.decimalFormat)) return false;
return true;
}
}
我期待其他类似主题的答案,但答案看起来像我上面的代码。希望有人知道原因。我希望测试的输出能够通过,但是由于期望,实际输出是处理完成,退出代码为-1。”
答案 0 :(得分:2)
问题是您将JUnit 3与JUnit 4混合使用。通过在测试类定义中使用extends TestCase
,您告诉JUnit该类应作为JUnit 3测试用例运行({{ 1}}是JUnit 3类)。
TestCase
和@Test
批注来自JUnit 4-JUnit 3测试用例的运行者对这些批注一无所知,因此将其注视。
要修复您的测试,只需删除@Rule
,一切正常。 JUnit 4至少需要一个extends TestCase
注释才能将类解释为测试用例。
