java - 使用 Maven 命令执行特定的 JUnit 测试用例

Question

我已经编写了一个新的 JUnit 测试用例，我想使用 maven 命令对其进行编译。我正在尝试从具有 pom.xml 的位置执行此命令，这是命令-

mvn -Dtest=src\test\java\absolute\path\of\JUnit\test\hello_Test.java test

这是我得到的输出(表示没有要运行的测试)-

您不需要完整路径来运行特定测试，test 选项的值实际上是一个模式。

自official documentation起

Specify this parameter to run individual tests by file name, overriding the includes/excludes parameters. Each pattern you specify here will be used to create an include pattern formatted like **/${test}.java, so you can just type "-Dtest=MyTest" to run a single test called "foo/MyTest.java". The test patterns prefixed with a ! will be excluded.

所以你甚至可以简单地运行:

mvn -Dtest=hello_Test test

或者仔细检查您的输入，以防出现任何拼写错误(根据您的评论)。
