Spring Boot H2 简明教程
Spring Boot & H2 - Unit Test Service
要测试服务，我们需要以下注释和类——
-
@ExtendWith(SpringExtension.class) ——使用SpringExtension类将类标记为以测试用例运行。
-
@SpringBootTest(classes = SprintBootH2Application.class) - 配置 Spring Boot 应用程序。
-
@MockBean private EmployeeService employeeService - 要测试的 EmployeeService 模拟对象。
以下是 EmployeeServiceTest 的完整代码。
