android-testing開始使用android測試

備註

測試類型

Android測試基於JUnit，您可以將它們作為JVM上的本地單元測試或Android設備上的檢測測試運行。此頁面介紹了構建Android測試的概念和工具

• 本地單元測試（位於module-name / src / test / java /）
• 檢測測試（位於module-name / src / androidTest / java /）

本地單元測試JUnit

@RunWith(AndroidJUnit4.class)
@LargeTest
public class MainActivityInstrumentationTest {

    @Rule
    public ActivityTestRule mActivityRule = new ActivityTestRule<>(
            MainActivity.class);

    @Test
    public void sayHello(){
        onView(withText("Say hello!")).perform(click());

        onView(withId(R.id.textView)).check(matches(withText("Hello, World!")));
    }
}
 

檢測測試示例依賴項{androidTestCompile'c​​om.android.support:support-annotations:24.0.0'androidTestCompile'c​​om.android.support.test：runner：0.5'androidTestCompile'c​​om.android.support.test：rules：0.5'/ /可選 - Hamcrest庫androidTestCompile'org.hamcrest：hamcrest-library：1.3'//可選 - 使用Espresso androidTestCompile進行UI測試'com.android.support.test.espresso：espresso-core：2.2.2'//可選 - 使用UI Automator進行UI測試androidTestCompile'c​​om.android.support.test.uiautomator：uiautomator-v18：2.1.2'}

android {defaultConfig {testInstrumentationRunner“android.support.test.runner.AndroidJUnitRunner”}}

        assertThat(createdFromParcelData.get(0).second, is(TEST_LONG));
