问题描述
我正在尝试使用 Roboelectric 运行一个简单的单元测试，但是在尝试构建 Activity 时，我收到以下错误：
new Blob([response.data])罪魁祸首似乎是这一行：java.lang.Exception: Main looper has queued unexecuted runnables. This might be the cause of the test failure. You might need a shadowOf(getMainLooper()).idle() call.

我的测试文件非常简单：
java.lang.NoSuchFieldError: tag_on_apply_window_listener其他测试都没有问题。
解决方法
你在使用 gradle 设置吗
testImplementation "androidx.core:core-ktx:+" ?
如果是这样，请尝试使用固定版本，例如 1.3.2。 我可以通过那个解决同样的问题。 看来 ViewCompat 的实现已更改。
