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") }

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)) }
