如何从 Android Studio 在 Compose Multiplatform 中运行测试？ （命令行有效）

Question

我目前正在尝试在我的第一个 Compose 多平台项目中进行测试设置。

我已按照此处的说明进行操作：

https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-test.html#writing-and-running-tests-with-compose-multiplatform

到目前为止，我可以使用以下命令从命令行成功运行测试：

./gradlew :composeApp:connectedAndroidTest

当我尝试从 Android Studio (GUI) 运行它们时，出现以下错误：

java.lang.NullPointerException: Cannot invoke "String.toLowerCase(java.util.Locale)" because "android.os.Build.FINGERPRINT" is null

这是我的测试：

class GameViewModelTest {
@OptIn(ExperimentalTestApi::class)
@Test
fun helloTestingCM() = runComposeUiTest {
    setContent {
        var text by remember { mutableStateOf("Hello") }
        Text(
            text = text,
            modifier = Modifier.testTag("text")
        )
        Button(
            onClick = { text = "Compose" },
            modifier = Modifier.testTag("button")
        ) {
            Text("Click ma")
        }
    }

    // Tests the declared UI with assertions and actions of the Compose Multiplatform testing API
    onNodeWithTag("text").assertTextEquals("Hello")
    onNodeWithTag("button").performClick()
    onNodeWithTag("text").assertTextEquals("Chompose")
}

}

我还遗漏了什么或者其他人也遇到过这个错误吗？我认为这是因为当我通过命令行运行时，它在真实设备上运行并且缺少依赖项。

我指的是 https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-test.html#62f6e1cb 中的相同测试示例，面临相同的错误。 据我了解，您只能从终端运行 Android 测试： “目前，您无法使用 Android（本地）测试配置运行常见的 Compose Multiplatform 测试，因此 Android Studio 中的装订线图标不会有任何帮助。”
