我有春季申请。我在使用时看到不同的行为

1 -

运行为-> jUnit 测试

在应用程序

这是好作品。

2-

运行为-> Maven 测试

在万无一失的报告中，我看到了很长的痕迹。原因：

java.lang.NoClassDefFoundError: Lcom/epam/hhsystem/util/DatabaseHelper;

我怎么知道什么配置使用了 Maven？

我在 Spring Tool Suite 中开发

更新

如果我尝试

Project -> Clean

之后

mvn clean test从 cmd 我看到

您需要了解 Maven 生命周期。通过运行 maven test，您正在运行构建周期 maven 的验证、编译和测试阶段。

您可以检查您的 Maven 依赖项管理，以确保该类java.lang.NoClassDefFoundError: Lcom/epam/hhsystem/util/DatabaseHelper 位于包含测试用例的项目的 Maven 托管依赖项中。

构建周期

  1. 验证- 验证项目是否正确并且所有必要的信息都可用
  2. compile - 编译项目的源代码
  3. 测试- 使用合适的单元测试框架测试编译的源代码。这些测试不应该要求打包或部署代码
  4. package - 获取编译后的代码并将其打包成可分发的格式，例如 JAR。
  5. 集成测试- 如有必要，将包处理并部署到可以运行集成测试的环境中
  6. 验证- 运行任何检查以验证包是否有效并符合质量标准
  7. install - 将包安装到本地存储库中，作为本地其他项目的依赖项
  8. 部署- 在集成或发布环境中完成，将最终包复制到远程存储库以与其他开发人员和项目共享。
