android-testing開始使用android測試


備註

本節概述了android-testing是什麼,以及開發人員為什麼要使用它。

它還應該提到android-testing中的任何大型主題,並鏈接到相關主題。由於android-testing文檔是新的,您可能需要創建這些相關主題的初始版本。

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));
