启动 Activity 进行测试

Question

我有一个使用 Realm db 的测验应用程序。每次用户选择一个答案时，她都会单击一个按钮，然后会出现新的问题文本。 就是这样，直到她到达终点，我开始一个新的 Activity 并根据正确答案显示分数。

我应该如何开始/测试（我猜是 Espresso）该活动，而不必每次所有答案都手动输入，并在每个答案后单击按钮，直到我到达最后一个？ p>

我需要将一些模拟数据传递给一个变量并创建一个 Intent，但我不知道如何在 Espresso 中找到与此相关的任何内容

Answer 1

您可以使用如下自定义意图启动您的下一个活动：

@RunWith(AndroidJUnit4.class)
public class NextActivityTest {

  @Rule
  public ActivityTestRule<NextActivity> activityRule 
     = new ActivityTestRule<>(
        NextActivity.class,
        true,     // initialTouchMode
        false);   // launchActivity. False to customize the intent

  @Test
  public void intent() {
    Intent intent = new Intent();
    intent.putExtra("your_key", "your_value");

    activityRule.launchActivity(intent);

    // Continue with your test
  }
}

对于使用 AndroidX 进行测试的开发者来说，情况有所改变。

这是一个示例 UI 测试用例，用于测试我的预期活动是否在单击文本视图后打开。

import androidx.lifecycle.Lifecycle
import androidx.test.core.app.ActivityScenario
import androidx.test.espresso.Espresso.onView
import androidx.test.espresso.action.ViewActions
import androidx.test.espresso.intent.Intents
import androidx.test.espresso.intent.Intents.intended
import androidx.test.espresso.intent.matcher.IntentMatchers.hasComponent
import androidx.test.espresso.matcher.ViewMatchers.withId
import com.softway.dhananjay.tournamentapp.tournament.TournamentActivity
import org.junit.Test

class MainActivityTest {

    @Test
    fun tournament_activity_starts_onClick_of_textView() {

        Intents.init()

        val activityScenario: ActivityScenario<MainActivity> =
            ActivityScenario.launch(MainActivity::class.java)


        activityScenario.moveToState(Lifecycle.State.RESUMED)

        onView(withId(R.id.startTextView)).perform(ViewActions.click())

        intended(hasComponent(TournamentActivity::class.java.name))

        Intents.release()

        activityScenario.moveToState(Lifecycle.State.DESTROYED)

    }
}

首先，看到这个问题：Android Monkey Runner

然后你可以看到这些指南：Monkey Runner

它使您可以使用 Python 在源代码之外测试您的 android 活动。因此，您可以像这样触发事物并进入特定活动：

#! /usr/bin/env monkeyrunner

from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
from random import randint

print "get device"
device = MonkeyRunner.waitForConnection()
package = 'my.packaget'
activity = 'my.package.activity'
runComponent = package + '/' + activity
device.startActivity(component=runComponent)

#use commands like device.touch and device.drag to simulate a navigation and open my activity

#with your activity opened start your monkey test
print "start monkey test"
for i in range(1, 1000):
    #here i go emulate only simple touchs, but i can emulate swiper keyevents and more... :D
    device.touch(randint(0, 1000), randint(0, 800), 'DOWN_AND_UP')

print "end monkey test"

保存然后运行：monkeyrunner test.py

private void launchApp(){
        // Launch the app
        Context context = InstrumentationRegistry.getContext();
        final Intent intent = context.getPackageManager()
                .getLaunchIntentForPackage(BASIC_SAMPLE_PACKAGE);
        // Clear out any previous instances
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        context.startActivity(intent);

        // Wait for the app to appear
        device.wait(Until.hasObject(By.pkg(BASIC_SAMPLE_PACKAGE).depth(0)),
                LAUNCH_TIMEOUT);
    }

Answer 5

您可以使用以下代码使用意图启动拨号器活动。

    @Rule    
public IntentsTestRule<DialerActivity> mActivityRule = new IntentsTestRule<>(
            DialerActivity.class);

    private static final String PHONE_NUMBER = "1234567890";
    private static final Uri INTENT_DATA_PHONE_NUMBER = Uri.parse("tel:" + PHONE_NUMBER);
    private static String PACKAGE_ANDROID_DIALER = "com.android.phone";

    static {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            // Starting with Android Lollipop the dialer package has changed. 

            PACKAGE_ANDROID_DIALER = "com.android.server.telecom";
        }
    }

    @Test    public void testDialerIntent()throws Exception
    {
        intending(not(isInternal())).respondWith(new Instrumentation.ActivityResult(Activity.RESULT_OK, null));
        onView(withId(R.id.edit_text_caller_number)).perform(typeText(PHONE_NUMBER));
        onView(withId(R.id.button_call_number)).perform(click());
        intended(allOf(
                hasAction(Intent.ACTION_CALL),
                hasData(INTENT_DATA_PHONE_NUMBER),
                toPackage(PACKAGE_ANDROID_DIALER)));
    }


}
