我正在尝试使用Espresso for

Android进行一系列测试.运行之间似乎没有关闭活动.一次测试后,无论应用程序状态如何,左侧为下一次测试.

如何用Espresso来实现？

错误报告中提供的修复程序的问题是,这将仅在整个套件的完成时执行.如果你想在每次测试后都有一个干净的活动堆栈,你需要手动做一些事情.我写了一个类似于上面提到的机票的修复程序,但可以在任何时间点执行.

import android.app.Activity;

import android.os.Handler;

import android.os.Looper;

import com.google.android.apps.common.testing.testrunner.ActivityLifecycleMonitor;

import com.google.android.apps.common.testing.testrunner.ActivityLifecycleMonitorRegistry;

import com.google.android.apps.common.testing.testrunner.Stage;

import java.util.ArrayList;

import java.util.EnumSet;

import java.util.List;

public final class ActivityFinisher implements Runnable {

public static void finishOpenActivities() {

new Handler(Looper.getMainLooper()).post(new ActivityFinisher());

}

private ActivityLifecycleMonitor activityLifecycleMonitor;

public ActivityFinisher() {

this.activityLifecycleMonitor = ActivityLifecycleMonitorRegistry.getInstance();

}

@Override

public void run() {

final List activities = new ArrayList();

for (final Stage stage : EnumSet.range(Stage.CREATED,Stage.STOPPED)) {

activities.addAll(activityLifecycleMonitor.getActivitiesInStage(stage));

}

for (final Activity activity : activities) {

if (!activity.isFinishing()) {

activity.finish();

}

}

}

}
