JavaFX + maven + TestFX +单片机不能一起工作
我在maven下有一个用于恶魔JavaFX + TestFX的小项目。 我用：
- Java（TM）SE运行时环境（版本1.8.0_40-b26）
- Apache Maven 3.2.5（12a6b3acb947671f09b81f49094c53f426d8cea1; 2014-12-14T21：29：23 + 04:00）

我有两个我无法解决的问题：
1）当我从IDE（IDEA）启动AppFXTest时，测试失败
java.lang.ClassNotFoundException: com.sun.glass.ui.monocle.MonoclePlatformFactory at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at com.sun.glass.ui.PlatformFactory.getPlatformFactory(PlatformFactory.java:42) at com.sun.glass.ui.Application.run(Application.java:146) at com.sun.javafx.tk.quantum.QuantumToolkit.startup(QuantumToolkit.java:263) at com.sun.javafx.application.PlatformImpl.startup(PlatformImpl.java:211) at com.sun.javafx.application.LauncherImpl.startToolkit(LauncherImpl.java:675) at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:695) at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$152(LauncherImpl.java:182) at com.sun.javafx.application.LauncherImpl$$Lambda$4/367732825.run(Unknown Source) at java.lang.Thread.run(Thread.java:745) Failed to load Glass factory class 如果我禁用Monocle，它可以工作。 但我看到真正的JavaFX窗口和真正的光标点击按钮（“非无头”模式）
2）当我尝试通过maven执行测试（evecute mvn clean test ）时，我得到了另一个错误

我的pom.xml看起来像

AppFXTest
public final class AppFXTest extends ApplicationTest { @Override public void start(final Stage stage) throws Exception { new AppFX().start(stage); } @Test public void showsButtons() throws Exception { MatcherAssert.assertThat( lookup(".button").queryAll().size(), Matchers.is(2) ); } @Test public void showsBottom() throws Exception { final Label label = lookup("BOTTOM").queryFirst(); MatcherAssert.assertThat( label.isVisible(), Matchers.is(true) ); } @Test public void clicksButtons() throws Exception { clickOn("A").clickOn("B"); } }
应用

更新
问题
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test (default-test) on project testfx-maven-example: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test failed: java.lang.NoClassDefFoundError: javafx/stage/Stage: javafx.stage.Stage -> [Help 1]
通过像这样添加到pom.xml additionalClasspathElements来解决
org.apache.maven.plugins maven-surefire-plugin 2.18.1 ... ${java.home}/lib/ext/jfxrt.jar
Failed to load Glass factory class
我曾经也有过这个错误，在我的情况下，我手动构建Monocle .jar并将其复制到JVM（jre / lib / ext）。
根据https://github.com/TestFX/Monocle上的文档构建Monocle，或者从OpenJDK存储库构建它。
所以以下对我有用：
- 将您构建的Monocle .jar复制到JDK的jre / lib / ext。
- 使用以下JVM参数运行应用程序：
-Dtestfx.robot=glass -Dglass.platform=Monocle -Dmonocle.platform=Headless -Dprism.order=sw
-Dtestfx.robot=glass是必要的，因为TestFX否则使用AWTRobot，它使用系统事件队列移动鼠标。 也许这足以使您的测试正常工作。
看看你的pom.xml ，junit带来了它自己的hamcrest-core版本，所以你应该排除它以避免问题（如果你想导入几个hamcrest匹配器）。 我以前使用两者都有错误。
对于进一步的研究，@ ItachiUchiha提供的链接以及https://zentrieredich.wordpress.com/2014/12/23/javafx-testen-mit-monocle/上的post帮助我使用Monocle与TestFX合作。
我建议使用TestFX 3.x，因为4.x仍然是alpha版本。
关于如何测试应用程序和TestFX的工作的一个非常好的博客在下面给出：
