@pambrocio, welcome to Apache StreamPipes!
I have created an issue to fix the test TestSizeMeasureProcessor. If you comment on this issue, I can assign it to you.
Generally this issue is about to fix the test again, it is not necessary to use parameterized tests for that.

I suspect that the old test used these parameters:

/*
 249 bytes is the base size of an object when first tested.
 Allowing up to 250 bytes comparison error in case of inconsistent base sizes across platforms
*/
return Arrays.asList(new Object[][]{
  { BYTE_SIZE, 10240 - 249, 10240.0, 250.
  { KILOBYTE_SIZE, 10240 - 249, 10.0, 0.025},
  { MEGABYTE_SIZE, (1024 * 1024) - 249, 1.0, 0.0025}
});
 }

yes please do assign it. Can I introduce new enums to parameterize the test? Is my assumption correct that the project used JUNIT4 before and migrated to JUNIT5, causing the test case breakages? May I also know the branching convention how do I name my branch?

Can I introduce new enums to parameterize the test?

Sure. Feel free to perform any adjustments

Is my assumption correct that the project used JUNIT4 before and migrated to JUNIT5, causing the test case breakages?

Exactly

May I also know the branching convention how do I name my branch?

We do not have a strict naming convention for feature branches
In general you are free to call the branch as you like, but we suggest to use the Create a branch feature of GitHub

If you have any idea/suggestion about how to improve the tests, we are happy to hear about them

Just for context: There is a discussion about how to improve tests for pipeline elements in #2374 & #2375

may I ask how you normally run an individual test in intellij. I am getting this at the moment

Got a successful build, but I unsure if everything is all ok. since I don't know how to run an individual test:
