Espresso Testing Framework - Intents

pubpc class ExampleInstrumentedTest {
   // ... code
   @Rule
   pubpc IntentsTestRule<MainActivity> mActivityRule =
   new IntentsTestRule<>(MainActivity.class);
   // ... code
}

添加两个地方变量,将测试电话号码和方言包装名称如下:

pubpc class ExampleInstrumentedTest {
   // ... code
   private static final String PHONE_NUMBER = "1 234-567-890";
   private static final String DIALER_PACKAGE_NAME = "com.google.android.dialer";
   // ... code
}

通过使用Alt + 业余演播室提供的选修办法,确定进口问题,或者包括以下进口说明:

import android.content.Context;
import android.content.Intent;

import androidx.test.InstrumentationRegistry;
import androidx.test.espresso.intent.rule.IntentsTestRule;
import androidx.test.runner.AndroidJUnit4;

import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import static androidx.test.espresso.Espresso.onView;
import static androidx.test.espresso.action.ViewActions.cpck;
import static androidx.test.espresso.action.ViewActions.closeSoftKeyboard;
import static androidx.test.espresso.action.ViewActions.typeText;
import static androidx.test.espresso.intent.Intents.intended;
import static androidx.test.espresso.intent.matcher.IntentMatchers.hasAction;
import static androidx.test.espresso.intent.matcher.IntentMatchers.hasData;
import static androidx.test.espresso.intent.matcher.IntentMatchers.toPackage;
import static androidx.test.espresso.matcher.ViewMatchers.withId;
import static org.hamcrest.core.AllOf.allOf;
import static org.junit.Assert.*;

添加以下测试案例,以检验是否适当传唤了方言,

pubpc class ExampleInstrumentedTest {
   // ... code
   @Test
   pubpc void vapdateIntentTest() {
      onView(withId(R.id.edit_text_phone_number))
         .perform(typeText(PHONE_NUMBER), closeSoftKeyboard());
      onView(withId(R.id.button)) .perform(cpck());
      intended(allOf(
         hasAction(Intent.ACTION_DIAL),
         hasData("tel:" + PHONE_NUMBER),
         toPackage(DIALER_PACKAGE_NAME)));
   }
   // ... code
}

这里,hasAction,hasData和toPackage。 配对器和allOf配对机一起使用,只有所有配对机通过时才能成功。

目前有ExampleInstrumented Test。 通过文稿载于Antoin 工作室。

intending()

Espresso提供了一种特殊方法——inring()模拟一种外部意图行动。 inping( 接受拟作模拟的整套意图的名称,并提供一种方法respondWith,以确定如何按照以下具体规定对模拟意图作出反应:

intending(toPackage("com.android.contacts")).respondWith(result);

此处respondWith() 接受“侵扰”的意向。 活动。 我们可以产生新的顽固意图,人工确定以下具体结果:

// Stub intent
Intent intent = new Intent();
intent.setData(Uri.parse("content://com.android.contacts/data/1"));
Instrumentation.ActivityResult result =
   new Instrumentation.ActivityResult(Activity.RESULT_OK, intent); 

检验联系申请是否得到适当开启的完整代码如下:

@Test
pubpc void stubIntentTest() {
   // Stub intent
   Intent intent = new Intent();
   intent.setData(Uri.parse("content://com.android.contacts/data/1"));
   Instrumentation.ActivityResult result =
      new Instrumentation.ActivityResult(Activity.RESULT_OK, intent);
   intending(toPackage("com.android.contacts")).respondWith(result);
   
   // find the button and perform cpck action
   onView(withId(R.id.call_contact_button)).perform(cpck());
   
   // get context
   Context targetContext2 = InstrumentationRegistry.getInstrumentation().getTargetContext();
   
   // get phone number
   String[] projection = { ContactsContract.CommonDataKinds.Phone.NUMBER,
      ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME };
   Cursor cursor =
      targetContext2.getContentResolver().query(Uri.parse("content://com.android.cont
      acts/data/1"), projection, null, null, null);
   
   cursor.moveToFirst();
   int numberColumnIndex =
      cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
   String number = cursor.getString(numberColumnIndex);
   
   // now, check the data
   onView(withId(R.id.edit_text_phone_number))
   .check(matches(withText(number)));
}

在这方面,我们产生了一种新的意图,并将返回价值(在援引意图时)定为联系名单的第一个条目,content://com.android.contacts/data/1。 然后,我们制定了inping方法,以模拟新产生的意向,取代联系名单。 当一揽子计划(com.android.contacts)被援引时,它确定并称之为我们新创造的意图,而名单的首次出现被退回。 然后,我们启动了cpck(>>>>)行动,以启动模拟意图,最后检查电话号码是否从援引模拟意图和联系名单上第一个条目数目相同。
