[英]Kotlin Mockk Error: Missing calls inside verify { ... } block
I already read some issues with this or a similar error message (it is also ocurring for every {}), but none of them took me to a success result.我已经阅读了一些与此相关的问题或类似的错误消息(每个 {} 也会发生这种情况),但没有一个问题使我取得成功。
Any hints or suggestions on how to get this to work?有关如何使其工作的任何提示或建议?
Here is my setup and the Unit Test itself:这是我的设置和单元测试本身:
compileSdkVersion 29
defaultConfig {
minSdkVersion 19
targetSdkVersion 29
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
MockK version: 1.9.3.kotlin12
OS: Android
Kotlin version: 1.3.61
JDK version: jdk1.8.0_212
JUnit version: 4.12
Type of test: unit test
The stacktrace of the error:错误的堆栈跟踪:
io.mockk.MockKException: Missing calls inside verify { ... } block.

at io.mockk.MockKKt.verify(MockK.kt:139)
at io.mockk.MockKKt.verify$default(MockK.kt:136)
My Unit Test:我的单元测试:
@Test
fun logout_clearsDatabase() {
coroutineTestRule.testDispatcher.runBlockingTest {
// ARRANGE
database.dataDao().insert(listOf(DataDummies()))
// ACT
sut.logout()
// ASSERT
verify { database.clearAllTables() }
}
}
I have no clue what I did wrong here.我不知道我在这里做错了什么。 database.clearAllTables()
is a method provided by Room. database.clearAllTables()
是 Room 提供的方法。 The testDispatcher
is a TestCoroutineDispatcher()
provided by the androidx testing library. testDispatcher
是 androidx 测试库提供的TestCoroutineDispatcher()
。
UPDATE / ANSWER更新/答案
Thanks to the input of @Juan Cruy Soler I changed the way of injecting the database.感谢@Juan Cruy Soler 的输入,我改变了注入数据库的方式。 I did not return the real room database, instead I return a spy of it.我没有返回真实的房间数据库,而是返回了它的间谍。 That way the spy is injected into the SUT as well as into my test class.这样间谍就被注入到 SUT 以及我的测试类中。 After that change the test runs as excpected.更改后,测试按预期运行。 I this a feasible solution to my problem?我这是解决我问题的可行方法吗? Does it make sense to let the (Testing-)DependencyInjection create a spy?让 (Testing-)DependencyInjection 创建间谍有意义吗?
database
should be mock or a spy to call verify on it. database
应该是模拟或间谍来调用验证。
I assume that it's not a mock because you are calling the method dataDao()
in a previous line.我认为这不是模拟,因为您在前一行调用了dataDao()
方法。
database.dataDao().getData()
returns an empty list and remove the verify
line.如果您不想模拟它而使用真实数据库,您应该检查database.dataDao().getData()
返回一个空列表并删除verify
行。database.dataDao().insert(listOf(DataDummies()))
如果你嘲笑它,那么你可以删除这一行database.dataDao().insert(listOf(DataDummies()))
You should use skyk to simulte a real scenario.您应该使用 skyk 来模拟真实场景。
val database = spyk<YouDataBaseReference>()
Doing that, you'll able to use functions.这样做,您将能够使用函数。
