将 JMockit 与第谷一起使用
Using JMockit with Tycho
我有几个 Eclipse 插件项目，我想使用 Maven 和 Tycho 进行编译。该项目可以在 github 找到。在那里您会看到三个项目及其 pom.xml 文件。我的目标是 运行 使用 JMockit 进行单元测试。
为了启动 Maven，我切换到 maven.parent 目录并执行 mvn clean verify，它会产生以下输出：
D:\maven-test\maventest.parent>mvn clean verify

所以我得出结论，-javaagent 是必需的。令人困惑：当使用 eclipse 运行 测试时，它就像一个魅力！
传递给 -javaagent 并因此用于 运行 测试的 jmockit-1.20.0.jar 与 eclipse 存储库中的完全相同。我还在测试中添加了 @RunWith(JMockit.class) 。正如here所述，我使用了所有三种方法。
那么你知道我能做什么吗？
我找到了解决方案：如果我使用 Run As -> JUnit Test 在 Eclipse 中执行测试，一切正常。如果我使用 Run As -> JUnit Plugin Test 执行测试，则会发生相同的错误。研究没有结果，JMockit 的支持是 cancelled ("won't fix").
由于 "normal" 测试运行良好，我可以使用 "normale" maven-surefire-plugin 而不是 tycho-surefire-plugin。唯一的区别是测试阶段（test 而不是 integration-test）并且没有 OSGi 环境（我不需要）。 POM文件中的解决方案如下。

我有几个 Eclipse 插件项目，我想使用 Maven 和 Tycho 进行编译。该项目可以在 github 找到。在那里您会看到三个项目及其 pom.xml 文件。我的目标是 运行 使用 JMockit 进行单元测试。
为了启动 Maven，我切换到 maven.parent 目录并执行 mvn clean verify，它会产生以下输出：

所以我得出结论，-javaagent 是必需的。令人困惑：当使用 eclipse 运行 测试时，它就像一个魅力！
传递给 -javaagent 并因此用于 运行 测试的 jmockit-1.20.0.jar 与 eclipse 存储库中的完全相同。我还在测试中添加了 @RunWith(JMockit.class) 。正如here所述，我使用了所有三种方法。
那么你知道我能做什么吗？
我找到了解决方案：如果我使用 Run As -> JUnit Test 在 Eclipse 中执行测试，一切正常。如果我使用 Run As -> JUnit Plugin Test 执行测试，则会发生相同的错误。研究没有结果，JMockit 的支持是 cancelled ("won't fix").
由于 "normal" 测试运行良好，我可以使用 "normale" maven-surefire-plugin 而不是 tycho-surefire-plugin。唯一的区别是测试阶段（test 而不是 integration-test）并且没有 OSGi 环境（我不需要）。 POM文件中的解决方案如下。
