Spring @kotlin应用程序的MockBean测试不工作

spring kotlin

Spring @kotlin应用程序的MockBean测试不工作,spring,kotlin,mocking,Spring,Kotlin,Mocking,我有一个看起来非常简单的用例，我想模拟一个Springbean。我试过几次，但运气不好。下面是我得到错误的代码的最简单版本： io.mockk.MockKException: Failed matching mocking signature for left matchers: [any(), any(), eq(foo-topic)] 导入io.mockk.mockk 导入org.junit.jupiter.api.Test 导入org.junit.jupiter.api.extens

我有一个看起来非常简单的用例，我想模拟一个Springbean。我试过几次，但运气不好。下面是我得到错误的代码的最简单版本：

io.mockk.MockKException: Failed matching mocking signature for

left matchers: [any(), any(), eq(foo-topic)]


导入io.mockk.mockk

插入调试器，我可以看到pubsubproductertracerv2正在被模拟，所以该部分似乎正在工作

任何提示谢谢！感谢您使用此依赖项提供的匹配项。。com.nhaarman.mockitokotlin2 mockito kotlin 2.2.0测试

    Suppressed: org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Misplaced or misused argument matcher detected here:

-> at PubsubApplicationIntegrationTest.publish and consume with tracing(PubsubApplicationIntegrationTest.kt:40)

You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
    when(mock.get(anyInt())).thenReturn(null);
    doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject());
    verify(mock).someMethod(contains("foo"))

This message may appear after an NullPointerException if the last matcher is returning an object 
like any() but the stubbed method signature expect a primitive argument, in this case,
use primitive alternatives.
    when(mock.get(any())); // bad use, will raise NPE
    when(mock.get(anyInt())); // correct usage use

Also, this error might show up because you use argument matchers with methods that cannot be mocked.
Following methods *cannot* be stubbed/verified: final/private/equals()/hashCode().
Mocking methods declared on non-public parent classes is not supported.
