Je voudrais tester des méthodes qui ont des éléments de scène JavaFX comme TextField ou DatePicker. J'ai trouvé ici How do you unit test a JavaFX controller with JUnit comment exécuter le test pour l'application JavaFX et ça marche bien pour moi si je n'ai qu'une seule classe de test où le Thread est initialisé. Mais qu'en est-il si j'ai deux cours? Je ne suis pas en mesure d'initialiser le même thread avec la méthode de lancement car une exception sera levée. Si je ne crée pas de thread dans la deuxième classe de test, il existe également une autre exception. Vous trouverez ci-dessous des classes de test et une trace de pile. Je pensais aussi à arrêter ce thread dans la méthode avec l'annotation @AfterClass, puis à le redémarrer en deuxième classe, mais je ne pense pas que ce soit possible. Est-ce que quelqu'un peut m'aider?JavaFX avec Junit
FirstTestClass
@RunWith(PowerMockRunner.class)
@PrepareForTest({TextField.class, DatePicker.class})
public class FirstTestClass {
@BeforeClass
public static void javaFXInitializer() throws SQLException, InterruptedException {
Thread thread = new Thread("JavaFX Init Thread") {
public void run() {
Application.launch(Main.class);
}
};
thread.setDaemon(true);
thread.start();
Thread.sleep(5000);
}
@Test
public void firstTest() {
TextField textFieldMock = mock(TextField.class);
DatePicker datePickerMock = mock(DatePicker.class);
TestClass objectUnderTest = new TestClass();
when(textFieldMock.getText()).thenReturn("2000");
when(datePickerMock.getValue()).thenReturn(LocalDate.of(1992,1,1));
//rest of code to test
}
}
SecondTestClass
@RunWith(PowerMockRunner.class)
@PrepareForTest({TextField.class, DatePicker.class})
public class SecondTestClass {
@BeforeClass
public static void javaFXInitializer() throws SQLException, InterruptedException {
Thread thread = new Thread("JavaFX Init Thread") {
public void run() {
Application.launch(Main.class);
}
};
thread.setDaemon(true);
thread.start();
Thread.sleep(5000);
}
@Test
public void firstTest() {
TextField textFieldMock = mock(TextField.class);
DatePicker datePickerMock = mock(DatePicker.class);
TestClass objectUnderTest = new TestClass();
when(textFieldMock.getText()).thenReturn("5000");
when(datePickerMock.getValue()).thenReturn(LocalDate.of(1990,1,1));
//rest of code to test
}
}
