我正在使用JUnit和MockK在Kotlin中编写一个单元测试来测试我的自定义Gradle任务。

open class CopySourceTask @Inject constructor(
    private val config: MyCustomExtension
) : DefaultTask() {

    @TaskAction
    override fun run() {
        if (!config.enableCopyConfig) {
            return
        }

        val sourceSetContainer =
            project.extensions.getByType(SourceSetContainer::class.java)

        project.copy {
            // Copy project source
            it.from(sourceSetContainer.getByName(SourceSet.MAIN_SOURCE_SET_NAME))
            it.into("${project.buildDir}/private/src")
        }
    }
}

字符串
下面是我的单元测试：

@ExtendWith(MockKExtension::class)
class CopySourceTaskTest {
    @MockK
    lateinit var customExtension: MyCustomExtension

    @MockK
    lateinit var dependencyEnabled: Property<Boolean>

    @MockK
    lateinit var sourceSetContainer: SourceSetContainer

    @BeforeEach
    fun setup() {
        every { customExtension.enableCopyConfig } returns dependencyEnabled
    }

    @Test
    fun testCopy() {
        val project = spyk(ProjectBuilder.builder().build())
        every { dependencyEnabled.get() } returns true
        every { project.extensions.getByType(SourceSetContainer::class.java) } returns sourceSetContainer
        val gradleTask = project.tasks.register(
            "CopySourceTask",
            CopySourceTask::class.java,
            customExtension
        )
       
        gradleTask.get().run()

       // Verify statements here
    }
}

型
单元测试由于以下错误而出错：org.gradle.api.UnknownDomainObjectException: Extension of type ‘SourceSetContainer’ does not exist. Currently registered extension types: [ExtraPropertiesExtension]。
看起来every { project.extensions.getByType(…)语句没有被接受，它试图从项目中加载SourceSetContainer，而不是mocked语句。请让我知道我错过了什么。
