我在单元测试中使用Mockito 2和Espresso,在仪器测试中使用Mockito 2时遇到了一个问题。运行测试时,我发现以下错误

这是测试代码。

 @Test
fun testUserResultReturnsEmpty() {

    val userMock = Mockito.mock(UserModel::class.java)
    Mockito.`when`(ArmOpApplication.getUserFromPrefs()).thenReturn(userMock)

    mActivityRule.launchActivity(Intent())
    mCountDownLatch.await(3000, TimeUnit.MILLISECONDS)

    assertNotNull(mActivityRule.activity.mInsightCategories)

    assertNull(mActivityRule.activity.mData)
    assertNull(mActivityRule.activity.insightsRecyclerView.adapter)
}

我在谷歌上搜索了更多信息,发现我需要使用mockito android而不是mockito core,并在应用程序的构建中添加了这些行。gradle文件

androidTestImplementation "org.mockito:mockito-android:${libMockitoAndroidVersion}"
androidTestImplementation 'com.linkedin.dexmaker:dexmaker-mockito:2.2.0'

where libMockitoAndroidVersion = 2.16.0

此外,我还添加了org。莫基托。插件。MockMaker文件放入androidTest资源目录中,以使用Kotlin的类。

有没有办法解决这个问题?任何帮助都将不胜感激。

使用Android替换

androidTestImplementation "org.mockito:mockito-core:$mockito_core_version"
androidTestImplementation "org.mockito:mockito-inline:$mockito_core_version"

对于

androidTestImplementation "org.mockito:mockito-android:$mockito_core_version"

我的版本是: $mockito_core_version = '2.28.2'

我遇到了这个问题,这里的任何解决方案都不适合我。我的问题是我混合了两个mockito库

//BAD CODE
testImplementation "org.mockito.kotlin:mockito-kotlin:4.0.0"
testImplementation "org.mockito:mockito-android:3.3.3"


//GOOD CODE - just use one
testImplementation "org.mockito.kotlin:mockito-kotlin:4.0.0"

我也有类似的问题。我的案例在 resource/mockito-extensions/org.mockito.plugins.MockMaker 文件在某些重构过程中,IDE替换了正确的值:

mock-maker-inline

使用此选项:

infrastructure-maker-inline

我在查看提交差异时注意到了意外的更改,因为它在第一次查看时看起来并不可疑。

这对我很有帮助

androidTestImplementation("org.koin:koin-test:1.0.2")
{ exclude("org.mockito", "mockito-inline") }
androidTestImplementation("org.mockito:mockito-android:2.24.5")

Koin表示一些包含org的库。莫基托

在stacktrace中,我发现:

Caused by: java.lang.IllegalStateException: Failed to load interface org.mockito.plugins.MockMaker implementation declared in sun.misc.CompoundEnumeration

受此启发( #824 Exception when using mock-maker-inline ),我通过添加工具解决了相同的问题。jar到intellij中的我的类路径

add tools.jar to classpath

从堆栈跟踪来看,您似乎使用的是内联字节好友模拟生成器,它在Android上不起作用。请确保您没有以某种方式传递它,因为两个可用的插件都会首先加载添加到类路径的插件。
