使用Junit 4.4或更高版本运行Eclipse Junit插件测试 - 为什么没有检测到测试？

Question

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(junit44和junit45)中的junit 4.4或4.5 bundle运行时,未检测到测试.可以使用eclipse获得的org.junit4包提供junit 4.3(从Ganymead/Eclipse 3.4开始).org.junit4包确实可以识别并运行测试,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:

java.lang.Exception: No runnable methods

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中运行测试作为JUnit插件测试,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"添加必需的插件"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MANIFEST.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).

Answer 1

我不知道它是哪个版本的 JUnit，但要成功找到测试，测试方法名称必须以单词“ test ”开头。

在较新的版本中，您可以简单地使用 @Test 标记测试，对我来说，它可以按以下组合工作：

import static junit.framework.Assert.*;
...
@Test
    public void testDummy() throws Exception
