Unit test fails in gradle test task

Support
#1

I have written a Unit test class as follow. I can run the test in IDEA by right click -> Run ‘ArticleEditInteractionTest’ successfully. I met an error when running gradle test.

Do you know what’s wrong with my unit test?

1. ArticleEditInteractionTest

public class ArticleEditInteractionTest {

@Rule
public TestUiEnvironment environment =
        new TestUiEnvironment(BlogWebTestContainer.Common.INSTANCE).withUserLogin("admin");

private Article article;

@Before
public void setUp() throws Exception {

    TestServiceProxy.mock(NumberIdService.class, new NumberIdService() {
        @Override
        public Long createLongId(String entityName, String sequenceName) {
            return new Long(1);
        }

        @Override
        public Long createCachedLongId(String entityName, String sequenceName) {
            return new Long(1);
        }
    });

    TestEntityFactory<Article> articleFactory =
            environment.getContainer().getEntityFactory(Article.class, TestEntityState.NEW);
    article = articleFactory.create(Collections.emptyMap());
}

@Test
public void testGenerateName() {
    Screens screens = environment.getScreens();
    screens.create(MainScreen.class, OpenMode.ROOT);
    ArticleEdit articleEdit = screens.create(ArticleEdit.class);
    articleEdit.setEntityToEdit(article);
    articleEdit.show();
    assertNull(articleEdit.getEditedEntity().getTitle());
    TextArea content = (TextArea) articleEdit.getWindow().getComponent("contentField");
    articleEdit.onContentFieldTextChange(new TextInputField.TextChangeEvent(content, "Test", 0));

    Button btn = (Button) articleEdit.getWindow().getComponent("popupMessageButton");
    articleEdit.popupMessage(new Button.ClickEvent(btn));
    articleEdit.getEditedEntity().setTitle("Title1");
    articleEdit.getEditedEntity().setContent("Hellow");
    articleEdit.closeWithCommit();
}

}

Thanks! I have figured out where the problem is.

I have two test classes using the codes below.

    Screens screens = environment.getScreens();
    screens.create(MainScreen.class, OpenMode.ROOT);

Through debug, I can see that the first test class is passed when it runs to “screens.create(MainScreen.class, OpenMode.ROOT);”, but the second class doesn’t, it throws an exception.

It seems that the code “screens.create(MainScreen.class, OpenMode.ROOT);” can run once in a JVM, and that explains why it works if I run test class one by one and fails when I run gradle test command, for when I run gradle test, two test classes run in one JVM.

I merged the test codes into one test class, it proves me correct! It works!!!
