I am new to JUnit and spring frameworks, When I was writing test cases to my spring files I ended up getting an error where I couldn't fix it. Here are some snippets attached below ask me if you need more.

Pom.xml

    <!-- Spring framework --> 



<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.6.RELEASE</version>
</dependency>

Thanks ask me any files if you need.

Probably it's a version conflict. You use an old version of base Spring (2.5.6) with a newer version (4.1.6.RELEASE) of other Spring packages. Look at this post: Could not load TestContextBootstrapper - Spring Unit testing

  • No change even I change the old version to something new. – Srikanth Pragallapati Jan 19 '17 at 09:35
  • Have you tried to rerun maven with clean command for example `mvn clean test`? Another thing might be the fact that you don't have to include junit in your dependencies because it is already included in spring-test. Could you post your pom.xml after changes you have made? – luke Jan 19 '17 at 09:48
  • I retested your case in my project. I made a small mistake. You still need junit dependecy, but when you add it to your current pom.xml the pom.xml shoud be ok. I think the problem is there `@ContextConfiguration(locations={ ... })`. It seems that you don't import context properly, so spring doesn't see it. Maybe pathes to files are somehow wrong or configuration in these files is somehow wrong. In my app I have context imported properly and tests work properly, but when I comment out `@ContextConfiguration( ... )` I get the same error as you so thus I think problem lies in a mentioned place – luke Jan 19 '17 at 10:32
  • the same way I commented the @contextconfiguration...ended up with same error! I was frustrating with this bro. – Srikanth Pragallapati Jan 19 '17 at 11:00
  • I have spring configuration in java file like in `AppConfig.java` in https://www.mkyong.com/unittest/junit-spring-integration-example/ but without `@ComponentScan(basePackages = {"com.mkyong.examples.spring"})` So my `AppConfig.java` is: `import org.springframework.context.annotation.Configuration; @Configuration public class AppConfig { }`. I have this `AppConfig.java` in src/main/java. And in test I have `@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = AppConfig.class)`. Maybe you could try the same. – luke Jan 19 '17 at 11:24
  • Before it worked for me and once I updated my code from svn this problem came may be version conflict is the main problem. But i cleaned server, project and maven clean but I couldn't resolve the issue. – Srikanth Pragallapati Jan 19 '17 at 11:26
  • I see. I'm sure you will deal with this problem sooner or later. Sometimes you just need some time and often with a fresh mind and knowledge from previous research you suddenly resolve in a short time something that bothered you for hours. I'm affraid that with my current knowledge and without access to full source code I can't give you any more advice. But if you think there is something I can do for you feel free to ask. – luke Jan 19 '17 at 11:47
  • Thanks @luke ping me in skype if possible id: srikanth4372 – Srikanth Pragallapati Jan 19 '17 at 11:55
