WorkManager ile entegrasyon testleri

WorkManager, bir Çalışanlarınızın test edilmesine yardımcı olan work-testing yapı.

Kurulum

work-testing yapısını kullanmak için androidTestImplementation olarak ekleyin. build.gradle konusunda bağımlılık.

Eski

dependencies {
    def work_version = "2.5.0"

    ...

    // optional - Test helpers
    androidTestImplementation "androidx.work:work-testing:$work_version"
}

Kotlin

dependencies {
    val work_version = "2.4.0"

    ...

    // optional - Test helpers
    androidTestImplementation("androidx.work:work-testing:$work_version")
}

Bağımlılık ekleme hakkında daha fazla bilgi için Bağımlılıkları bildirme bölümündeki WorkManager sürüm notları.

Kavramlar

work-testing, test modu için özel bir WorkManager uygulaması sağlar. Bu sürüm, WorkManagerTestInitHelper

work-testing yapısı ayrıca bir SynchronousExecutor Böylece ile uğraşmak zorunda kalmaz.

Aşağıda, tüm bu sınıfların birlikte nasıl kullanılacağına dair bir örnek verilmiştir.

Kotlin

@RunWith(AndroidJUnit4::class)
class BasicInstrumentationTest {
    @Before
    fun setup() {
        val context = InstrumentationRegistry.getTargetContext()
        val config = Configuration.Builder()
            .setMinimumLoggingLevel(Log.DEBUG)
            .setExecutor(SynchronousExecutor())
            .build()

        // Initialize WorkManager for instrumentation tests.
        WorkManagerTestInitHelper.initializeTestWorkManager(context, config)
    }
}

Java

@RunWith(AndroidJUnit4.class)
public class BasicInstrumentationTest {
    @Before
    public void setup() {
        Context context = InstrumentationRegistry.getTargetContext();
        Configuration config = new Configuration.Builder()
                .setMinimumLoggingLevel(Log.DEBUG)
                .setExecutor(new SynchronousExecutor())
                .build();

        // Initialize WorkManager for instrumentation tests.
        WorkManagerTestInitHelper.initializeTestWorkManager(
            context, config);
    }
}

Yapılandırma Testleri

WorkManager, test modunda başlatıldığına göre artık test etmeye hazırsınız. nasıl sağlayabileceğini de öğreneceksiniz.

inputData beklenen bir EchoWorker'ınız olduğunu ve girişini outputData hedefine kopyalar (yankılar).

Kotlin

class EchoWorker(context: Context, parameters: WorkerParameters)
   : Worker(context, parameters) {
   override fun doWork(): Result {
       return when(inputData.size()) {
           0 - >Result.failure()
           else - >Result.success(inputData)
       }
   }
}

Java

public class EchoWorker extends Worker {
  public EchoWorker(Context context, WorkerParameters parameters) {
      super(context, parameters);
  }

  @NonNull
  @Override
  public Result doWork() {
      Data input = getInputData();
      if (input.size() == 0) {
          return Result.failure();
      } else {
          return Result.success(input);
      }
  }
}

Temel Testler

Aşağıda, EchoWorker ürününü test eden bir Android Enstrümanı testi bulunmaktadır. Ana ana fikir şudur: EchoWorker, test modunda test edildiğinde gerçek bir uygulamada EchoWorker kullanmanız gerekir.

Kotlin

@Test
@Throws(Exception::class)
fun testSimpleEchoWorker() {
    // Define input data
    val input = workDataOf(KEY_1 to 1, KEY_2 to 2)

    // Create request
    val request = OneTimeWorkRequestBuilderE<choWorker(>)
        .setInputData(input)
        .build()

    val workManager = WorkManager.getInstance(applicationContext)
    // Enqueue and wait for result. This also runs the Worker synchronously
    // because we are using a SynchronousExecutor.
    workManager.enqueue(request).result.get()
    // Get WorkInfo and outputData
    val workInfo = workManager.getWorkInfoById(request.id).get()
    val outputData = workInfo.outputData

    // Assert
    assertThat(workInfo.state, `is`(WorkInfo.State.SUCCEEDED))
    assertThat(outputData, `is`(input))
}

Java

@Test
public void testSimpleEchoWorker() throws Exception {
   // Define input data
   Data input = new Data.Builder()
           .put(KEY_1, 1)
           .put(KEY_2, 2)
           .build();

   // Create request
   OneTimeWorkRequest request =
       new OneTimeWorkRequest.Builder(EchoWorker.class)
           .setInputData(input)
           .build();

   WorkManager workManager = WorkManager.getInstance(getApplicationContext());
   // Enqueue and wait for result. This also runs the Worker synchronously
   // because we are using a SynchronousExecutor.
   workManager.enqueue(request).getResult().get();
   // Get WorkInfo and outputData
   WorkInfo workInfo = workManager.getWorkInfoById(request.getId()).get();
   Data outputData = workInfo.getOutputData();

   // Assert
   assertThat(workInfo.getState(), is(WorkInfo.State.SUCCEEDED));
   assertThat(outputData, is(input));
}

EchoWorker hiç giriş almadığında bunu garanti eden başka bir test yazalım verileri, beklenen Result bir Result.failure().

Kotlin

@Test
@Throws(Exception::class)
fun testEchoWorkerNoInput() {
   // Create request
   val request = OneTimeWorkRequestBuilderE<choWorker(>)
       .build()

   val workManager = WorkManager.getInstance(applicationContext)
   // Enqueue and wait for result. This also runs the Worker synchronously
   // because we are using a SynchronousExecutor.
   workManager.enqueue(request).result.get()
   // Get WorkInfo
   val workInfo = workManager.getWorkInfoById(request.id).get()

   // Assert
   assertThat(workInfo.state, `is`(WorkInfo.State.FAILED))
}

Java

@Test
public void testEchoWorkerNoInput() throws Exception {
  // Create request
  OneTimeWorkRequest request =
      new OneTimeWorkRequest.Builder(EchoWorker.class)
         .build();

  WorkManager workManager = WorkManager.getInstance(getApplicationContext());
  // Enqueue and wait for result. This also runs the Worker synchronously
  // because we are using a SynchronousExecutor.
  workManager.enqueue(request).getResult().get();
  // Get WorkInfo
  WorkInfo workInfo = workManager.getWorkInfoById(request.getId()).get();

  // Assert
  assertThat(workInfo.getState(), is(WorkInfo.State.FAILED));
}

Kısıtlamaları, gecikmeleri ve periyodik işleri simüle etme

WorkManagerTestInitHelper, size TestDriver simüle etmek için kullanır. Gecikme süresi için kısıtlamaların PeriodicWorkRequest için ListenableWorker örnek ve aralıklar sağlar.

İlk Gecikmeleri Test Etme

Çalışanlarda ilk gecikmeler yaşanabilir. EchoWorker uygulamasını initialDelay ile test etmek için testinizde initialDelay için beklemek yerine TestDriver öğesini kullanarak iş isteğinin ilk gecikmesini setInitialDelayMet.

Kotlin

@Test
@Throws(Exception::class)
fun testWithInitialDelay() {
    // Define input data
    val input = workDataOf(KEY_1 to 1, KEY_2 to 2)

    // Create request
    val request = OneTimeWorkRequestBuilderE<choWorker(>)
        .setInputData(input)
        .setInitialDelay(10, TimeUnit.SECONDS)
        .build()

    val workManager = WorkManager.getInstance(getApplicationContext())
    // Get the TestDriver
    val testDriver = WorkManagerTestInitHelper.getTestDriver()
    // Enqueue
    workManager.enqueue(request).result.get()
    // Tells the WorkManager test framework that initial delays are now met.
    testDriver.setInitialDelayMet(request.id)
    // Get WorkInfo and outputData
    val workInfo = workManager.getWorkInfoById(request.id).get()
    val outputData = workInfo.outputData

    // Assert
    assertThat(workInfo.state, `is`(WorkInfo.State.SUCCEEDED))
    assertThat(outputData, `is`(input))
}

Java

@Test
public void testWithInitialDelay() throws Exception {
  // Define input data
  Data input = new Data.Builder()
          .put(KEY_1, 1)
          .put(KEY_2, 2)
          .build();

  // Create request
  OneTimeWorkRequest request = new OneTimeWorkRequest.Builder(EchoWorker.class)
          .setInputData(input)
          .setInitialDelay(10, TimeUnit.SECONDS)
          .build();

  WorkManager workManager = WorkManager.getInstance(myContext);
  // Get the TestDriver
  TestDriver testDriver = WorkManagerTestInitHelper.getTestDriver();
  // Enqueue
  workManager.enqueue(request).getResult().get();
  // Tells the WorkManager test framework that initial delays are now met.
  testDriver.setInitialDelayMet(request.getId());
  // Get WorkInfo and outputData
  WorkInfo workInfo = workManager.getWorkInfoById(request.getId()).get();
  Data outputData = workInfo.getOutputData();

  // Assert
  assertThat(workInfo.getState(), is(WorkInfo.State.SUCCEEDED));
  assertThat(outputData, is(input));
}

Kısıtlamaları Test Etme

Kısıtlamaları karşılandı olarak işaretlemek için TestDriver kullanılabilir. setAllConstraintsMet. Worker cihazını nasıl test edebileceğinize dair bir örnek tercih edebilirsiniz.

Kotlin

@Test
@Throws(Exception::class)
fun testWithConstraints() {
    // Define input data
    val input = workDataOf(KEY_1 to 1, KEY_2 to 2)

    val constraints = Constraints.Builder()
        .setRequiredNetworkType(NetworkType.CONNECTED)
        .build()

    // Create request
    val request = OneTimeWorkRequestBuilderE<choWorker(>)
        .setInputData(input)
        .setConstraints(constraints)
        .build()

    val workManager = WorkManager.getInstance(myContext)
    val testDriver = WorkManagerTestInitHelper.getTestDriver()
    // Enqueue
    workManager.enqueue(request).result.get()
    // Tells the testing framework that all constraints are met.
    testDriver.setAllConstraintsMet(request.id)
    // Get WorkInfo and outputData
    val workInfo = workManager.getWorkInfoById(request.id).get()
    val outputData = workInfo.outputData

    // Assert
    assertThat(workInfo.state, `is`(WorkInfo.State.SUCCEEDED))
    assertThat(outputData, `is`(input))
}

Java

@Test
public void testWithConstraints() throws Exception {
    // Define input data
    Data input = new Data.Builder()
            .put(KEY_1, 1)
            .put(KEY_2, 2)
            .build();

    // Define constraints
    Constraints constraints = new Constraints.Builder()
            .setRequiresDeviceIdle(true)
            .build();

    // Create request
    OneTimeWorkRequest request = new OneTimeWorkRequest.Builder(EchoWorker.class)
            .setInputData(input)
            .setConstraints(constraints)
            .build();

    WorkManager workManager = WorkManager.getInstance(myContext);
    TestDriver testDriver = WorkManagerTestInitHelper.getTestDriver();
    // Enqueue
    workManager.enqueue(request).getResult().get();
    // Tells the testing framework that all constraints are met.
    testDriver.setAllConstraintsMet(request.getId());
    // Get WorkInfo and outputData
    WorkInfo workInfo = workManager.getWorkInfoById(request.getId()).get();
    Data outputData = workInfo.getOutputData();

    // Assert
    assertThat(workInfo.getState(), is(WorkInfo.State.SUCCEEDED));
    assertThat(outputData, is(input));
}

Periyodik Çalışmaları Test Etme

TestDriver, aşağıdakileri yapmak için kullanılabilecek bir setPeriodDelayMet de sunar: bir aralığın tamamlandığını belirtir. Elektronik tablo kullanarak yapılmış setPeriodDelayMet kullanılıyor.

Kotlin

@Test
@Throws(Exception::class)
fun testPeriodicWork() {
    // Define input data
    val input = workDataOf(KEY_1 to 1, KEY_2 to 2)

    // Create request
    val request = PeriodicWorkRequestBuilderE<choWorker(>15, MINUTES)
        .setInputData(input)
        .build()

    val workManager = WorkManager.getInstance(myContext)
    val testDriver = WorkManagerTestInitHelper.getTestDriver()
    // Enqueue and wait for result.
    workManager.enqueue(request).result.get()
    // Tells the testing framework the period delay is met
    testDriver.setPeriodDelayMet(request.id)
    // Get WorkInfo and outputData
    val workInfo = workManager.getWorkInfoById(request.id).get()

    // Assert
    assertThat(workInfo.state, `is`(WorkInfo.State.ENQUEUED))
}

Java

@Test
public void testPeriodicWork() throws Exception {
    // Define input data
    Data input = new Data.Builder()
            .put(KEY_1, 1)
            .put(KEY_2, 2)
            .build();

    // Create request
    PeriodicWorkRequest request =
            new PeriodicWorkRequest.Builder(EchoWorker.class, 15, MINUTES)
            .setInputData(input)
            .build();

    WorkManager workManager = WorkManager.getInstance(myContext);
    TestDriver testDriver = WorkManagerTestInitHelper.getTestDriver();
    // Enqueue and wait for result.
    workManager.enqueue(request).getResult().get();
    // Tells the testing framework the period delay is met
    testDriver.setPeriodDelayMet(request.getId());
    // Get WorkInfo and outputData
    WorkInfo workInfo = workManager.getWorkInfoById(request.getId()).get();

    // Assert
    assertThat(workInfo.getState(), is(WorkInfo.State.ENQUEUED));
}
