[英]AssertJ-Swing and Junit 5 support
我目前正在使用 JUnit Jupiter 测试 Java 应用程序。 我开始在 GUI 上工作,我想知道是否可以将 AssertJ-Swing 与 JUnit 5 一起使用。事实上,我在 AssertJ-Swing GitHub 页面上发现了一个未解决的问题。
他们给出的建议是像这样定义一个 GUITestExtension:
import org.assertj.swing.junit.runner.ImageFolderCreator;
import org.junit.jupiter.api.extension.Extension;
import org.junit.jupiter.api.extension.ExtensionContext;
import org.junit.jupiter.api.extension.InvocationInterceptor;
import org.junit.jupiter.api.extension.ReflectiveInvocationContext;
import java.lang.reflect.Method;
import static org.assertj.swing.annotation.GUITestFinder.isGUITest;
import static org.assertj.swing.junit.runner.Formatter.testNameFrom;
/**
* Understands a JUnit 5 extension that takes a screenshot of a failed GUI test.
* The Junit 4 runner is available in {@link org.assertj.swing.junit.runner.GUITestRunner}.
*
* @see <a href="https://github.com/assertj/assertj-swing/issues/259">assertj-swing #259</a>
* @author William Bakker
*/
public class GUITestExtension implements Extension, InvocationInterceptor {
private final FailureScreenshotTaker screenshotTaker;
public GUITestExtension() {
screenshotTaker = new FailureScreenshotTaker(new ImageFolderCreator().createImageFolder());
}
@Override
public void interceptTestMethod(
Invocation<Void> invocation,
ReflectiveInvocationContext<Method> invocationContext,
ExtensionContext extensionContext)
throws Throwable {
try {
invocation.proceed();
} catch (Throwable t) {
takeScreenshot(invocationContext.getExecutable());
throw t;
}
}
private void takeScreenshot(Method method) {
final Class<?> testClass = method.getDeclaringClass();
if (!(isGUITest(testClass, method)))
return;
screenshotTaker.saveScreenshot(testNameFrom(testClass, method));
}
}
我对可以与 JUnit 4 一起使用的 GUITestRunner 有点熟悉,但我不知道如何用它来替换它。
注意:通常 GUITestRunner 与 JUnit 4 一起使用:
import org.assertj.swing.junit.runner.GUITestRunner;
import org.assertj.swing.junit.testcase.AssertJSwingJUnitTestCase;
import org.junit.runner.RunWith;
import org.assertj.swing.edt.GuiActionRunner;
import org.assertj.swing.fixture.FrameFixture;
@RunWith(GUITestRunner.class)
public class WelcomeSwingViewTest extends AssertJSwingJUnitTestCase{
private FrameFixture window;
private WelcomeSwingView welcomeSwingView;
@Override
protected void onSetUp() {
GuiActionRunner.execute(() -> {
welcomeSwingView = new WelcomeSwingView();
return welcomeSwingView;
});
window = new FrameFixture(robot(), welcomeSwingView);
window.show();
}
}
任何帮助表示赞赏。
我根据 Stefano 的回答更改了我的测试 class ,现在一切正常。 如果有人需要它,我的测试 class 代码是这样的:
import org.assertj.swing.core.matcher.JLabelMatcher;
import org.assertj.swing.edt.GuiActionRunner;
import org.assertj.swing.fixture.FrameFixture;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
@ExtendWith(GUITestExtension.class)
class WelcomeSwingViewTest {
private FrameFixture window;
private WelcomeSwingView welcomeSwingView;
@BeforeEach
void setup() {
GuiActionRunner.execute(() -> {
welcomeSwingView = new WelcomeSwingView();
return welcomeSwingView;
});
window = new FrameFixture(welcomeSwingView);
window.show();
}
@Test
void testControlsInitialStates() {
window.label(JLabelMatcher.withText("label"));
}
}
当然,您还必须将GUITestExtension
(在我的问题中定义)导入您的测试 class。 测试也是成功的,因为在我看来,我有一个带有文本“标签”的label
。
