Android Espresso:按顺序运行多个测试

错误报告中提供的修复程序的问题是,这只会在完成整个套件时执行.如果您希望在每次测试后都有一个干净的活动堆栈,则需要手动执行某些操作.我写了一个小类,与上面提到的票证上的修复程序非常相似,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<Activity> activities = new ArrayList<Activity>();

        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();
            }
        }
    }
}
