我需要在一组 eclipse 插件测试中使用 JUnit 4.4(或更新版本),但我遇到了以下问题:
使用 springsource 中的 junit 4.4 或 4.5 包(junit44和junit45)运行时未检测到测试。可以用 eclipse 获得的 org.junit4 包提供了 junit 4.3(从 Ganymead / Eclipse 3.4 开始)。org.junit4 包确实可以识别和运行测试,但它与最新版本的 JMock 不兼容,我需要使用模拟库。
这是一个示例测试:
package testingplugin;
import static org.junit.Assert.*;
import org.junit.Test;
public class ActivatorTest {
@Test
public final void testDoaddTest() {
fail("Not yet implemented");
}
}
运行此测试时,我收到以下异常:

但是,如果我将项目依赖项从 com.springsource.org.junit 切换到 org.junit4,则测试运行并失败(如预期的那样)。
我在 Eclipse 中将测试作为 JUnit 插件测试运行,具有以下程序参数:
-os ${target.os} -ws ${target.ws} -arch ${target.arch} -nl ${target.nl}
在启动期间选择了以下插件(由我选择,然后我使用“添加所需的插件”来获取其余的依赖项。):
Workspace:
testingPlugin
Target Platform:
com.springsource.org.hamcrest.core (1.1.0)
com.springsource.org.junit (4.5.0)
....and a bunch of others... (nothing related to testing was auto-selected)
这是我的清单.MF:
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: TestingPlugin Plug-in
Bundle-SymbolicName: testingPlugin
Bundle-Version: 1.0.0
Bundle-Activator: testingplugin.Activator
Import-Package: org.osgi.framework;version="1.3.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
Require-Bundle: com.springsource.org.junit;bundle-version="4.5.0"
将最后一行切换为:
Require-Bundle: org.junit4;bundle-version="4.3.1"
并在启动时将选定的插件更新为:
Workspace:
testingPlugin
Target Platform:
org.junit4 (4.3.1)
...bunches of auto-selected bundles... (again, nothing else test related)
使测试正常运行(但使用错误的 junit 版本)。
