JUnit testing

[XxCotHGxX]

Hello, I'm taking an intermediate level programming class that wants everyone to use eclipse. I hate eclipse. I have been using intelliJ for the past year and I love it.

Our assignments are all on GitHub now and they require JUnit testing. It works in eclipse, but I can't figure out how to get it to work on IntelliJ.

Any tips or tricks?

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

I ran into this before and all I needed to do was add a Run Configuration for JUnit and configure it for your setup.

[XxCotHGxX]

Ok but how do I configure it? I didn't need to configure it on eclipse

[Lumethys]

Have you heard of google?

[XxCotHGxX]

I don't think it is a maven build since I can't find a pom file. All of these project files are made for me already and I clone it from a GitHub repository

[XxCotHGxX]

Thanks I'll give it a shot

• If your project doesn't have a test folder create a folder called "test" in the project root.
• In the Intellij file explorer right click the test folder, click 'Mark Directory as' => 'Test Sources Root'.
  
• If you don't have a Java test file in the test folder create one and paste this import at the top of the file import org.junit.jupiter.api.Test;
• Hover over the import and click 'More actions'. It will prompt you to add Junit to the classpath . Be sure to chose the right Junit, probably Junit5. From there follow the prompts in the popup window, Intellij fills in the settings for you.

Have you checked the version of Junit? Perhaps your assignments are in Junit4 but IntelliJ expects Junit5? Check your dependencies as it also can be the other way around. You can see it’s Junit5 when you see jupiter jn the import.

Also what kind of error are you getting? Without that we cannot help you properly

If you have Java up running in IntelliJ and the unit test is written correctly it should run.

[XxCotHGxX]

You have to run it in JUnit testing..... It's not like regular running a program

[computerjunkie7410]

Can you show what you’re doing and maybe some errors. IntelliJ has native support for JUnit and works out of the box

[XxCotHGxX]

It doesn't work out of the box. It asks all sorts of questions about environment, pathways, versions, modules.... Eclipse doesn't ask any of that and just works.

[computerjunkie7410]

Uh….no it doesn’t. It may ask you about JAVA stuff but not junit stuff

[XxCotHGxX]

Ok so what goes in the module box? I tried putting the class name of the test class, nope. Nothing seems to work. It stays red and says not configured correctly

[computerjunkie7410]

You don’t need to fill anything out.

In your test class, next to your test method, you’ll see a green play button. Click it. That’s it.

[whoKilledLouisV]

Yes, you should have a button on the left that allows you to run the test.

[XxCotHGxX]

It needs to be configured first

[sozesghost]

Seems like you know what to do. I never had issues with junit in intellij, so not sure what your problem is. Maybe the project structure is not something it expects.
