当junit3在类路径上时,Mockito失败

mockito junit java

OhleC · 技术社区 · 7 年前

我在做一个有很多传统junit3测试的项目。我们最近已经切换到JUnit5,并通过JUnitVintage运行旧的测试。由于几个原因,我们不能轻易地摆脱junit3依赖,所以它仍然在类路径上(到目前为止还没有引起任何问题)。

mockito.verify() ,在捕获参数差异的测试中:

public class TestTestTest {
    interface Foo {
        void frobnicate(int a);
    }

    @Test
    void testMockito() {
        Foo foo = mock(Foo.class);
        foo.frobnicate(42);
        verify(foo).frobnicate(43);
    }
}

结果

java.lang.VerifyError: Bad return type

ArgumentsAreDifferent AssertionError ,但不是少年 断言错误

假设我不能摆脱junit3依赖,有解决方法吗?

我对莫基托也有同样的错误。但是有 com.google.android.tools:dx:1.7 而不是JUnit3。但是看起来这个依赖关系至少包含了一些JUnit3的包和类。问题是Mockito创造了 ArgumentsAreDifferent junit.framework.ComparisonFailure . 在JUnit 4中 ComparisonFailure 通过中间阶级 java.lang.AssertionError 比较失败 不延伸 AssertionError

我修复了它,只是排除了这个依赖性,因为它实际上不是我需要的。
