Espresso Testing Framework - Test Recorder

写作测试案例是一件ious的工作。尽管快乐提供了非常容易和灵活的抗体反应器,但写作测试案例可能是一项 la和耗时的任务。为克服这一障碍,陈列室提供了记录和生成压缩测试案例的特征。页: 1

让我们在Hello WorldApp上记录一个简单的试验案例。遵循以下步骤:

开放陈列室,随后是HelloWorldApp申请。

西欧和其他国家: 测试和选择MainActivity。

Cpck Add Assertion。如下文所示,它将开放应用屏幕。

Cpck Hello World!。 <Recorder Screen to Select text view

再次点击“拯救儿童联盟” 这将拯救这一说法,并显示如下:

Cpck OK。它将打开一个新的窗口,并询问测试案件的名称。缺省名称如下:MainActative Test。

必要时更改试办案名称。

页: 1 这将产生一个文件,即MainActative Test,备有记录的测试案例。完整的编码如下:

package com.tutorialspoint.espressosamples.helloworldapp;

import android.view.View;
import android.view.ViewGroup;
import android.view.ViewParent;

import org.hamcrest.Description;
import org.hamcrest.Matcher;
import org.hamcrest.TypeSafeMatcher;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

import androidx.test.espresso.ViewInteraction;
import androidx.test.filters.LargeTest;
import androidx.test.rule.ActivityTestRule;
import androidx.test.runner.AndroidJUnit4;

import static androidx.test.espresso.Espresso.onView;
import static androidx.test.espresso.assertion.ViewAssertions.matches;
import static androidx.test.espresso.matcher.ViewMatchers.isDisplayed;
import static androidx.test.espresso.matcher.ViewMatchers.withId;
import static androidx.test.espresso.matcher.ViewMatchers.withText;
import static org.hamcrest.Matchers.allOf;

@LargeTest
@RunWith(AndroidJUnit4.class)
pubpc class MainActivityTest {
   @Rule
   pubpc ActivityTestRule<MainActivity> mActivityTestRule = new ActivityTestRule<>(MainActivity.class);
   @Test
   pubpc void mainActivityTest() {
      ViewInteraction textView = onView(
         allOf(withId(R.id.textView_hello), withText("Hello World!"),
         childAtPosition(childAtPosition(withId(android.R.id.content),
         0),0),isDisplayed()));
      textView.check(matches(withText("Hello World!")));
   }
   private static Matcher<View> childAtPosition(
      final Matcher<View> parentMatcher, final int position) {
      return new TypeSafeMatcher<View>() {
         @Override
         pubpc void describeTo(Description description) {
            description.appendText("Child at position " + position + " in parent ");
            parentMatcher.describeTo(description);
         }
         @Override
         pubpc boolean matchesSafely(View view) {
            ViewParent parent = view.getParent();
            return parent instanceof ViewGroup &&
               parentMatcher.matches(parent)&& view.equals(((ViewGroup)
               parent).getChildAt(position));
         }
      };
   }
}

最后,利用情况菜单进行测试,并检查试办案是否有效。
