Hello! I am trying to set up my IntelliJ to run JUnit tests. I need to review the tests and their code coverage, but haven’t been able to get the Test Suite to run in IntelliJ. The other developer I am working with uses Eclipse exclusively and I am relatively new to IntelliJ myself. This is a shared repository and I can’t add any automation tools like Gradle, Maven, etc. Advice?

I’d like to avoid a switch to Eclipse if possible

ere are some steps you can follow to set up JUnit in IntelliJ:

Make sure you have the JUnit library added to your project. You can do this by going to File > Project Structure > Libraries, then click on the "+" button and select "From Maven..." to search for JUnit.
Create a new JUnit test class by right-clicking on your source folder, selecting New > Java Class, and choosing JUnit 4 test from the dropdown menu.
Write your test methods within this class, making sure to annotate them with @Test.
To run the tests, right-click on the test class file in the project explorer and select Run 'TestClass'.
To view code coverage, go to Run > Edit Configurations, select Defaults > JUnit, and check the box for "Code coverage".
Run your tests again, and you should now see code coverage results in the Run window.

If you are still having issues with setting up JUnit in IntelliJ, please provide more specific details about what errors or challenges you are facing so that we can offer more targeted assistance.

I have a JUnit test class given to me and am not given the option to run. Also, please ping me when you reply! I might not see it quickly otherwise

oblique adder I have a JUnit test class given to me and am not given the option to run. Also, ...

Which intellij version, and ultimate or CE? And you can't add a run configuration/right click run tests? Normally both Ultimate and CE support maven and gradle.

oblique adder Apr 25, 2024, 4:15 PM

#

Community Edition, working on getting an ultimate license but I’m the only one at my company using IntelliJ at this point (as far as I know everyone else uses eclipse or VSCode)

Need management approval for gradle, maven usage and don’t have it

sullen wind Apr 25, 2024, 4:16 PM

#

Ultimate has a 30 day free trial.

#

And what, you need management approval to use build tools?

oblique adder Apr 25, 2024, 4:17 PM

#

If it will add files to the repository, yes

finite anvil Apr 25, 2024, 4:17 PM

#

can u branch and alter there ?

oblique adder Apr 25, 2024, 4:17 PM

#

I can’t create a new branch without approval either

sullen wind Apr 25, 2024, 4:17 PM

#

Wait, how does your colleague manage his dependencies?

#

Do you all just download all jars to your machine, and add them to the classpath? How do you build your jar/war/images/...?

#

And you can always add folders to .gitignore. (assuming you are using a versioning system, and not just copying files).

oblique adder Apr 25, 2024, 4:18 PM

#

We are using atlassian Bitbucket

sullen wind Apr 25, 2024, 4:20 PM

#

Are you sure they didn't just mean your dependencies shouldn't be pushed to bitbucket?

oblique adder Apr 25, 2024, 4:20 PM

#

I’m not sure. I don’t typically work in Java, Im usually scripting in python but got added as a peer reviewer for this

finite anvil Apr 25, 2024, 4:20 PM

#

if your given the junit it should be on the repo aswell no ?

oblique adder Apr 25, 2024, 4:22 PM

#

I’m just meant to verify that the JUnit test class covers all cases of the actual code, was gonna run IntelliJ built in code coverage tool but can’t

sullen wind Apr 25, 2024, 4:22 PM

#

oblique adder I’m not sure. I don’t typically work in Java, Im usually scripting in python but...

Is there no readme if there's a special setup? Or why not ask them how to run it?

#

Or just look at sonar if your team has it (or an equivalent).

oblique adder Apr 25, 2024, 4:23 PM

#

sullen wind Is there no readme if there's a special setup? Or why not ask them how to run it...

No readme. We don’t have a linter set up. Colleague uses Eclipse but we have a configuration management team that does all build processes on a virtual machine

finite anvil Apr 25, 2024, 4:23 PM

#

is that test class in the project aswell ?

oblique adder Apr 25, 2024, 4:23 PM

#

I’m not 100% sure im supposed to even build locally

oblique adder Apr 25, 2024, 4:23 PM

#

finite anvil is that test class in the project aswell ?

Yes

finite anvil Apr 25, 2024, 4:23 PM

#

then junit is in the project aswell, else it would be a red hell of errors

oblique adder Apr 25, 2024, 4:24 PM

#

Fair enough

finite anvil Apr 25, 2024, 4:25 PM

#

what's on the right click menu of those test class(es) ?

oblique adder Apr 25, 2024, 4:26 PM

#

Light mode warning

finite anvil Apr 25, 2024, 4:27 PM

#

can u show more of the actual code ? (if allowed. Not seing any junit stuff )

sullen wind Apr 25, 2024, 4:27 PM

#

#

When you right click on the test class itself in the sidebar?

oblique adder Apr 25, 2024, 4:29 PM

#

sullen wind Apr 25, 2024, 4:31 PM

#

Oh boy, ant.

finite anvil Apr 25, 2024, 4:31 PM

#

makes me wonder, folder not marked as test folder @sullen wind ?

sullen wind Apr 25, 2024, 4:31 PM

#

It's normal.

finite anvil Apr 25, 2024, 4:31 PM

#

no icon on the test though

#

I know.

#

You opened/imported the wrong folder.

#

Only do it for SiMServer.

oblique adder Apr 25, 2024, 4:32 PM

#

Just asked my coworker, it can be set up to build locally but typically isn’t

oblique adder Apr 25, 2024, 4:36 PM

#

sullen wind Only do it for SiMServer.

Ah.

#

#

That helped. Def no JUnit in repo, tho

sullen wind Apr 25, 2024, 4:36 PM

#

Alternatively you can right click on the root folder => module settings => mark test folders.

#

Check the build.xml file to see how it's set up for JUnit.

Sorry for photos of a screen, I don’t have discord on my company computer

oblique adder

is there an ant task that downloads your deps?

#

it should be named either something obvious or something with ivy in it

oblique adder Apr 25, 2024, 4:48 PM

#

I didn’t see anything but my coworker forgot to include the JUnit in the jar file, so once that’s added it might fix it?

sullen wind Apr 25, 2024, 4:52 PM

#

JUnit is test scoped, so does not end up in the finalr jar.

oblique adder Apr 25, 2024, 4:53 PM

#

Hhhhm

sullen wind Apr 25, 2024, 5:08 PM

#

Is there no get-dependencies target?

#

Which usually depends on download/init-ivy.
