我刚刚下载了junit-4.10.jar。根据JUnit FAQ，您所要做的就是将 jar 文件解压缩到一个目录中，然后将 jar 文件放在您的类路径中，然后就可以安装了。然后，您可以通过使用以下命令运行示例测试来测试安装：

java org.junit.runner.JUnitCore org.junit.tests.AllTests

不过，FAQ 肯定是过时的，因为 AllTests 不驻留在 org.junit.tests 中，它驻留在 org.junit.runners 中。这就是我尝试使用 org.junit.tests 包中的 AllTests 运行示例测试时得到的结果。有人知道为什么样本测试失败了吗？是的，我检查了我的 CLASSPATH 并且 junit-4.10.jar 在那里。

C:\Users\username\Downloads\junit4.10-extracted>java org.junit.runner.JUnitCore org.junit.runners.AllTests

AllTests用于运行 JUnit 3.8 测试。如果查看源代码，您会发现它没有扩展 TestCase（JUnit 3.8 风格）或具有 @Test 方法（JUnit 4.0 风格）。它也没有公共的无参数构造函数。它不需要，因为它不是一个可以作为单元测试运行的类。

正如盛源所说，检查测试文件夹。您找到的 AllTests 类将位于源文件夹中，这意味着您可能在错误的文件夹中查找实际的示例测试。
