问题 I am following a Spring 2.5 tutorial and trying, at the same time, updating the code/setup to Spring 3.0. In Spring 2.5 I had the HelloController (for reference): public class HelloController implements Controller { protected final Log logger = LogFactory.getLog(getClass()); public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { logger.info("Returning hello view"); return new ModelAndView("hello.jsp"); } } And a JUnit

Is it possible to run incremental/automated JUnit testing in Eclipse?

由 烂漫一生 提交于 2020-01-20 02:43:45
问题 Eclipse support incremental compiling. If I save a source file then it will compile the modified files. Is it possible after such incremental compile also to run the JUnit tests of the same package and show the fail in the error view. Then I can see the JUnit test failing and compiling errors in the same view without extra action. Are there any plugins that can do it? 回答1: You have to look at these plugins: JUnit Max: Not free, developed by Kent Benk (one of the men behind the TDD practice);

MockMvc 来自Spring Test，它允许您通过一组方便的builder类向 DispatcherServlet 发送HTTP请求，并对结果作出断言。请注意，@AutoConfigureMockMvc 与@SpringBootTest 需要一起注入一个MockMvc 实例。在使用@SpringBootTest 时候，我们需要创建整个应用程序上下文。 示例代码: import org.junit.Test; import org.junit.runner.RunWith; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.http.MediaType; import org.springframework.test.annotation
