unit-testing - Groovy:junit 的面向测试的输出

Question

我正在尝试关注 the Groovy Testing Guide为我的 Groovy 代码编写一些 JUnit 测试，但我无法让它输出任何有用的内容。例如，如果我有这个:

class Test extends GroovyTestCase {
    void testCase1() {
        assertTrue true
        assertEquals 1, 1
    }
}

然后我得到这个:

$ groovy Test.groovy
.
Time: 0.045

OK (1 test)

作为基本输出，这很好，但如果我能获得一些有关实际运行的测试用例的信息，那就太好了。不过，一个更大的问题是失败时的输出:

class Test extends GroovyTestCase {
        void testCase1() {
                assertTrue true
                assertEquals 1, 1
        }

        void testCase2() {
                assertEquals 1, 2
        }

        void testCase3() {
                assertEquals 1, 2
        }
}

结果:

$ groovy Test.groovy
..F.F
Time: 0.046
There were 2 failures:
1) testCase2(Test)junit.framework.AssertionFailedError: expected:<1> but was:<2>

FAILURES!!!
Tests run: 3,  Failures: 2,  Errors: 0

这不是很好的输出。我不需要像这样的大量堆栈跟踪，尤其是实际上不会告诉我有关被测试代码的任何信息的堆栈跟踪。如果我能得到一些更面向测试的东西，比如:

testCase1: PASS
testCase2: FAIL 
    junit.framework.AssertionFailedError: expected:<1> but was:<2>
testCase3: FAIL
    junit.framework.AssertionFailedError: expected:<1> but was:<2>

FAILURES!!!
Tests run: 3,  Failures: 2,  Errors: 0

有没有办法从 Groovy 中的 JUnit 获得更多面向测试的输出？

Answer 1

我相信，您可以在内置方法 assert 中使用用户消息。

void testCase2() {
        assert 1 == 2, 'expected differs from actual'
}
