launchFragmentInContainer无法解析Android中的活动

Question

在编写使用的简单测试时launchFragmentInContainer，我收到以下错误消息：

java.lang.RuntimeException: Unable to resolve activity for: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.myapp.appname.debug/androidx.fragment.app.testing.FragmentScenario$EmptyFragmentActivity (has extras) }

基本测试类是：

class OneFragmentTest {

    @Test
    fun testOneFragmentState_checkTitleText() {
        val args = Bundle().apply {
            putString("dummyKey", "dummyValue")
        }
        launchFragmentInContainer<OneFragment>(args)

        onView(withId(R.id.tv_title)).check(matches(withText("title here")))
    }
}

我尝试更新AndroidManifest.xml以下内容：

java.lang.RuntimeException: Unable to resolve activity for: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.myapp.appname.debug/androidx.fragment.app.testing.FragmentScenario$EmptyFragmentActivity (has extras) }

但标签似乎instrumentation有效，但值用红色书写，因此我认为targetPackageand 出了点问题name。

我如何摆脱这个错误，并在OneFragment上运行一个简单的测试launchFragmentInContainer？

Answer 1

尝试这样配置

debugImplementation('androidx.fragment:fragment-testing:1.1.0') {
        // exclude androidx.test:core while fragment_testing depends on 1.1.0
        exclude group: 'androidx.test', module: 'core'
    }

Answer 2

The error was related to the way I did import the dependencies on Gradle.

Before:

androidTestImplementation("androidx.fragment:fragment-testing:1.1.0-beta01")
implementation("androidx.fragment:fragment-ktx:1.1.0-beta01")
androidTestImplementation("androidx.test:core:1.2.0")
androidTestImplementation("androidx.test:rules:1.2.0")
androidTestImplementation("androidx.test:runner:1.2.0")

After:

implementation("androidx.fragment:fragment-testing:1.1.0-beta01")
implementation("androidx.fragment:fragment-ktx:1.1.0-beta01")
implementation("androidx.test:core:1.2.0")
implementation("androidx.test:rules:1.2.0")
implementation("androidx.test:runner:1.2.0")

Changed from androidTestImplementation to implementation and it solved the issue. Compiling and running, and green test as result.
