Question

我刚刚开始为Android项目的UI测试编译类和模块。一个正在使用di，并且有必要在我的测试中注入一些依赖性。立即解决我的测试组件时遇到了一些麻烦。为了简化问题，我创建了一个空测试和一个空测试组件。尽管如此，该组件仍然无法解析，而同一构造已在另一个android项目中成功解析。

在我看来，使用这样的空组件可以切断大多数可以隐藏错误的地方，但gradle文件除外（无论如何都是错误的）。

这是组件和测试类：

class LoginTest {
    init {
        try {
            UiThreadStatement.runOnUiThread {
                val testTest: TestComponent = DaggerTestComponent
                    .builder()
                    .build()
            }
        } catch (throwable: Throwable) {
            throwable.printStackTrace()
        }
    }

    @Test
    fun test() {

    }
}

---------------------

@Component
interface TestComponent {

}

这是应用程序gradle：

apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

UPD：该错误非常无用，看起来像：

e: ...\LoginTest.kt: (11, 37): Unresolved reference: DaggerTestComponent
:app:compileMockDebugAndroidTestKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileMockDebugAndroidTestKotlin'.
> Compilation error. See log for more details

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Answer 1

我为谁几次前发布正确答案表示歉意。

要添加到gradle中的键字符串：

    kaptAndroidTest "com.google.dagger:dagger-compiler:$libraries.dagger"
    kaptAndroidTest "com.google.dagger:dagger-android-processor:$libraries.dagger"
