当我执行 mvn clean install 时，Junit 测试用例没有运行答案

【问题标题】：Junit test cases are not running when i do mvn clean install当我执行 mvn clean install 时，Junit 测试用例没有运行
【发布时间】：2019-02-28 03:48:18
【问题描述】：

我写了一个spring boot应用。我也为此编写了 Junit 测试用例。当我运行mvn clean install 命令时，测试用例没有作为该 mvn 构建的一部分运行。但是当我只是右键单击并作为 Junit 测试用例运行时，我的所有测试用例都会执行。我相信有一些配置错误。我正在使用 spring-boot、maven 作为构建和 Eclipse ide。

我的测试类名称是 TestService.java，它位于 src/test 文件夹中

public class TestService {

    JsonUtil jsonUtil;
    String jsonString;
    @Before
    public void setData() {
        jsonString = "{\"id\":\"one\"}";
        jsonUtil = new JsonUtil(new ObjectMapper());
    }

    @Test
    public void testGetStringAsJson() {

        JsonNode node = jsonUtil.getStringAsJson(jsonString);
        Assert.assertEquals("one", node.get("id").textValue());
    }

}

下面是我的 pom.xml

【问题讨论】：

TestService.java 相对于您的项目根目录的路径是什么？是src/test/TestService.java还是src/test/java/com/foo/bar/TestService.java
它是\src\test\java\com\...\TestService.java
运行下面给定的命令是否执行测试用例。如果是，请分享您的 pom.xml。 "mvn install -Dmaven.test.skip=false"
tree 的输出或项目结构的类似视图也会有所帮助。确保您的项目符合标准目录布局：maven.apache.org/guides/introduction/…
running clean install -Dmaven.test.skip=false 也没有运行测试

标签： java maven junit

【解决方案1】：

您将如何通过 spring 初始化程序或手动创建 pom？最有可能导致插件无法执行的构建路径问题。您可以通过 eclipse 运行后检查正在使用哪个版本，稍后通过 mvn 依赖项进行验证：tree 只是为了知道相同的版本也可以从 cmd 获得。

【讨论】：

【解决方案2】：

检查 pom.xml 转到“有效 POM”视图。检查标签下的值。它似乎没有指向正确的位置。如果 pom.xml 指向不同的位置，您可以覆盖该属性。

【讨论】：

我建议 OP 将代码移动到预期的标准位置，而不是更改 POM。您可以更改位置，但使用标准 maven 树通常会更好，因为要跟踪和管理的自定义项更少。
C:\Users\rk\Documents\xyz\abc\src\test\javaC:\Users\rk\Documents\xyz\abc\target \test-classes 这看起来是正确的
所有配置看起来都正确。尝试禁用 Maven 行为并再次启用它（如果使用 Eclipse）。
我也这样做了。没有运气:(
尝试在调试模式下运行构建并检查在surefire插件中发生了什么。 mvn test 也执行测试用例吗？
