如何在android中使用dagger对kotlin文件进行UI测试？

下面是我的堆栈跟踪，我已经查看了所有的问题和答案，但找不到任何解决方案

这个活动扩展了BaseActivity，它在下面的行中，因此在启动splash之后，我的测试失败，并且统计了lateinit var prefUtils尚未初始化，现在我使用了mocking，但仍然得到java.lang.IllegalStateException:无法初始化plugin:接口 org.mockito.plugins.MockMaker（可选：null）

我添加了如下依赖项：

testImplementation "junit:junit:$junitVersion"
testImplementation "org.mockito:mockito-core:$mockito"
testImplementation "org.mockito:mockito-inline:$mockito"

以下错误发生在我不嘲笑任何东西时

kotlin.UninitializedPropertyAccessException: lateinit property prefUtils has not been initialized

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

Test running failed: Instrumentation run failed due to 'Process crashed.'

正如baseActivity所做的那样 @注入 lateinit变量prefUtils:prefUtils 因此，为了解决这个错误，我使用Mock

现在我也尝试过power mock，但在编译时失败了！！，它说

Unresolved reference: powermock

下线

@RunWith(PowerMockRunner::class)

@Rule
@JvmField
var mActivityTestRule = ActivityTestRule(SplashActivity::class.java)

---

在这里，SplashActivity继承了BaseActivity，所以每当测试运行时，注入的变量对于测试都保持未初始化状态，所以我通过在下面的行中进行更改找到了解决方案

@RunWith(PowerMockRunner::class)

@Rule
@JvmField
var mActivityTestRule = ActivityTestRule(SplashActivity::class.java)

到

下面是FakeLogInActivity:：class.java的代码

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import com.sextpanther.sp.R

/**
* Used for testing fragments inside a fake activity.
*/
class FakeLogInActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_login)
  }
}

---

现在测试运行成功，但只有使用snackbar view matcher和文本的测试失败。

但为什么要在UI测试中模拟某些内容？@rom4ek请参阅更新的问题，因为我不知道模拟是解决方案，但要使测试运行成功，应该做些什么！

@Rule
@JvmField
var mActivityTestRule = ActivityTestRule(FakeLogInActivity::class.java)

import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import com.sextpanther.sp.R

/**
* Used for testing fragments inside a fake activity.
*/
class FakeLogInActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_login)
  }
}
