Android 单元测试失败 java.lang.IllegalArgumentException：需要 INTERNET 权限

Question

我正在尝试为我的应用程序设置单元测试。但是我遇到了 Segment

的问题

这是我的测试class:

@RunWith(RobolectricTestRunner::class)
@Config(sdk = [Build.VERSION_CODES.O_MR1])
class LoginViewModelTest {
    private lateinit var viewModel: LoginViewModel

    @Mock
    private lateinit var authService: AuthService

    @Mock
    private lateinit var sharedPreferences: SharedPreferences

    @Before
    fun setUp() {
        MockitoAnnotations.initMocks(this)
        val mMyApplication = mock<Application>()
        viewModel = LoginViewModel(mMyApplication, sharedPreferences, authService)
    }

    @Test
    fun test_phone(){
        viewModel.isPhone.observeForTesting {
            val isPhone = LiveDataTestUtil.getValue(viewModel.isPhone) ?: 
                return@observeForTesting
           Assert.assertFalse(isPhone)
        }
    }
}

失败并出现以下错误：

INTERNET permission is required.
java.lang.IllegalArgumentException: INTERNET permission is required.
    at com.segment.analytics.Analytics$Builder.<init>(Analytics.java:1068)
    at com.app.android.MyApplication.onCreate(MyApplication.kt:42)

MyApplication class 正在像这样初始化 Segment：

override fun onCreate() {
val analytics: Analytics = Analytics.Builder(  //This is where its failing
            applicationContext,
            this.getString(R.string.segmentApiKey)
        )
            .trackApplicationLifecycleEvents()
            .build()

        // Set the initialized instance as a globally accessible instance.
        Analytics.setSingletonInstance(analytics)
}

我在 Whosebug

中找到了

他们建议我们必须像这样初始化应用程序：

protected Context instance() {
        ShadowApplication shadowApp = Shadows.shadowOf(this);
        shadowApp.grantPermissions("android.permission.INTERNET");

        return shadowApp.getApplicationContext();
    }

像这样将 instance() 传递给段：

Analytics.with(instance()).identify("userId", null, null);

我认为这不是正确的方法，因为我们正在更改单元测试的代码，恕我直言，这不是正确的方法。

无论如何我都试过了，但是失败了，因为它无法解析shadowApp.getApplicationContext()

我通过添加这个来使用 shadowApplication

implementation 'org.robolectric:shadow-framework:4.6'

请帮我解决这个问题。提前致谢。

如果使用 ShadowApplication 是正确的方法，请帮助我了解发生了什么。我对这段代码片段的理解是它是一个示例应用程序 class 或可用于测试的东西。请cmiiw.

编辑：我的 AndroidManifest.xml 已经拥有互联网权限

显然我的设置有问题

我添加了这些

// Required -- JUnit 4 framework
testImplementation 'junit:junit:4.13.2'
// Optional -- Robolectric environment
testImplementation 'androidx.test:core:1.4.0'
// Optional -- Mockito framework
testImplementation 'org.mockito:mockito-core:4.5.0'
// Optional -- mockito-kotlin
testImplementation "org.mockito.kotlin:mockito-kotlin:4.0.0"
// Optional -- Mockk framework
testImplementation 'io.mockk:mockk:1.12.3'
testImplementation 'androidx.test.ext:junit-ktx:1.1.3'
testImplementation 'org.robolectric:robolectric:4.6.1'
testImplementation 'org.mockito:mockito-inline:2.13.0'
testImplementation 'android.arch.core:core-testing:1.1.1'

并将我的测试 class 更改为如下所示：

@RunWith(MockitoJUnitRunner::class)
class LoginViewModelTest : TestCase() {
    @get:Rule
    var instantExecutorRule = InstantTaskExecutorRule()
    private lateinit var viewModel: LoginViewModel

    @Before
    public override fun setUp() {
        super.setUp()
        val mMyApplication = mock(Application::class.java)
        val sharedPreferences = mock(SharedPreferences::class.java)
        val authService = mock(AuthService::class.java)
        val analyticsFacade = mock(AnalyticsFacadeImpl::class.java)
        doNothing().`when`(analyticsFacade).trackEvent(anyString(), any())
        viewModel = LoginViewModel(
        mMyApplication, sharedPreferences, authService,
             analyticsFacade as AnalyticsFacadeImpl)
    }

    @Test
    fun test_phone(){
        viewModel.isPhone.observeForTesting {
            val isPhone = LiveDataTestUtil.getValue(viewModel.isPhone) ?: 
                return@observeForTesting
           Assert.assertFalse(isPhone)
        }
    }
}
