ActivityTestRule - 如何调用code应用程序的onCreate前 [英] ActivityTestRule - how to call code before Application's onCreate

问题描述

我使用的长者preSSO 2.1 ActivityTestRule，我正在寻找一种方法来设置一些静态的标志前的onCreate（）在我的应用程序将被称为。

I am using Espresso 2.1 with ActivityTestRule, and I am looking for a way to set some static flags before onCreate() in my application will be called.

我有一些初始化code，我不希望在仪器测试调用。

I have some init code that I don't want called during instrumentation tests.

推荐答案

ActivityTestRule自带的beforeActivityLaunched方法，你可以重写，它会被称为活动推出的权利之前。

ActivityTestRule comes with the beforeActivityLaunched method which you can override and it will be called right before activity is launched.

编辑：

原来，应用程序的onCreate被称为仪表的onCreate（）之后。在这种情况下，您可以创建自定义的测试运行，这将延长AndroidJUnitRunner并与您的自定义设置覆盖callApplicationOnCreate（）。

Turns out that Application onCreate is called after Instrumentation onCreate(). In this case you may create your custom test runner which will extend AndroidJUnitRunner and will override the callApplicationOnCreate() with your custom setup.

public class MyCustomTestRunner extends AndroidJUnitRunner {
@Override
public void callApplicationOnCreate(Application app) {
    InstrumentationRegistry.getTargetContext().getSharedPreferences().doMyStuff();
    super.callApplicationOnCreate(app);
}
}

请确保更新您的defaultConfig中的build.gradle使用新testInstrumentationRunner

Make sure to update your defaultConfig in the build.gradle to use new testInstrumentationRunner
