我想測試具有JavaFX場景元素（如TextField或DatePicker）的方法。我在這裏找到How do you unit test a JavaFX controller with JUnit如何運行JavaFX應用程序的測試，如果我只有一個線程初始化的測試類，它對我來說工作正常。但是如果我有兩節課呢？我無法使用啓動方法初始化相同的線程，因爲會引發異常。如果我不會在第二個測試類中創建線程，那麼還有另一個例外。您可以在下面找到測試類和堆棧跟蹤。我也在考慮使用@AfterClass註解方法停止此線程，然後再次在第二課中啓動它，但我認爲這不可能。有人可以幫助我嗎？JavaFX與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
}
}
例外，當我初始化線程兩類
