我正在试图找出IntelliJ/Android报告"空测试套件"的原因.我有一个带有两个IntelliJ模块的小项目(Eclipse中的"Projects").Unit测试模块有自己的AndroidManifest.xml,我在底部粘贴了它.我试图运行ActivityUnitTestCase,因为测试将取决于对象Context.

主模块的包名称是nilzor.myapp.测试模块的pacakge名称是nilzor.myapp.tests

为什么测试运行器没有检测到testBlah()-method作为测试？

我正在尝试为我的MainActivity编写一个检测测试.我按照这里给出的答案.Android Studio仍无法找到任何测试.我在androidTest文件夹中有ApplicationTest.java类.这是班级的内容:

package com.example.monicamarcus.mymusicplayer

import android.app.Activity;
import android.test.ActivityInstrumentationTestCase2;
import com.example.monicamarcus.mymusicplayer.MainActivity;

public class ApplicationTest extends ActivityInstrumentationTestCase2<MainActivity> { 
    public ApplicationTest() {
        super(MainActivity.class);
    }

    public void testNextTrackButton() throws Exception {
        Activity activity = getActivity();

        Button nextButton = (Button) activity.findViewById(R.id.nextTrackBt);
        activity.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                nextButton.performClick();
                assertTrue(currentPosition < songList.size());
            }});
        activity.finish();
    }
}

这个测试类出了什么问题？还是测试？我没有得到任何错误,它只是没有找到任何测试运行.运行ApplicationTest后,输出以以下行结束:

Running tests
Test running startedFinish
Empty test suite.

这是app的build.gradle文件:

apply plugin: 'com.android.application'
