在 运行 在 Android 上使用 Espresso 进行第二次测试之前终止所有活动

Question

我正在使用 Cucumber 和 Espresso。我有以下功能文件：

Feature: From Main to Profile 

  Background:
    Given User is registered
    And User is logged in

  @ios @android   Scenario: User can navigate from the home screen to the profile screen
    Given User is on the home screen
    When User taps Profile
    Then User is navigated to the profile screen

  @ios @android   Scenario: User can navigate from the profile screen back to the home screen
    Given User is on the Profile screen
    When User taps back
    Then User is navigated back to the home screen

在定义 Then User is navigated to the profile screen 的步骤中我必须添加一个 pressBack 否则第二个测试的 MainActivity 的开始不起作用（超时）我可以在模拟器上看到 ProfileActivity 仍然显示。

这是steps class:

public class MainActivitySteps extends BaseActivitySteps {

    public static final int PROFILE_BUTTON_ID = R.id.tvProfile;

    @Rule
    public ActivityTestRule<MainActivity> activityTestRule = new ActivityTestRule<>(MainActivity.class);
    @Rule
    public GrantPermissionRule permissionRule = GrantPermissionRule.grant(android.Manifest.permission.ACCESS_FINE_LOCATION);

    @Before
    public void setup() {
        activityTestRule.launchActivity(new Intent());
        activity = activityTestRule.getActivity();
        Intents.init();
    }

    @After
    public void tearDown() {
        activityTestRule.finishActivity();
        Intents.release();
    }

    @Given("^User is on the home screen")
    public void userIsAtMainScreen() {
        assertTrue(activity.findViewById(R.id.btnRecordTrip).getVisibility() == View.VISIBLE);
    }

    @When("^User taps Profile")
    public void userTapsProfile() {
        // wait for view to become visible
        userTaps(PROFILE_BUTTON_ID);
    }

    @Given("^User is on the Profile screen")
    public void userIsAtProfileScreen() {
        userTaps(PROFILE_BUTTON_ID);

    }

    @Then("^User is navigated to the profile screen")
    public void userIsNavigatedToTheProfileScreen() {
        intended(hasComponent(ProfileActivity.class.getName()));
        pressBack();
    }

    @When("^User taps back")
    public void userTapsBack() {
        pressBack();
    }

    @Then("^User is navigated back to the home screen$")
    public void userIsNavigatedBackToTheHomeScreen() {
        userIsAtMainScreen();
    }

}

我发现 this 这可能很有用，但令我惊讶的是我需要自己做：在我看来，这是一个基本的功能。 有没有更好的方法在第一次测试后杀死ProfileActivity？

Answer 1

这是我正在使用的：

dependencies {
    implementation "an androidx library:1.0.0"
    ...
}

android {
    defaultConfig {
        testInstrumentationRunnerArguments clearPackageData: 'true'
    }

    testOptions {
        animationsDisabled true
        execution 'ANDROIDX_TEST_ORCHESTRATOR'

        unitTests {
            includeAndroidResources true
        }
    }
}

所以请注意，我正在为依赖项和 Orchestrator 使用 AndroidX。

由于您没有使用 AndroidX，因此您需要使用 execution 'ANDROID_TEST_ORCHESTRATOR'。

如果您只是想终止活动，testInstrumentationRunnerArguments clearPackageData: 'true' 并不是绝对必要的。
