Fix JUnit Parameterized Tests

[tenthe]

Description

Due to the update from JUnit4 to JUnit5, we had to deactivate some tests that do not use the JUnit5 syntax for parameterized tests. Below you will find a list of these tests that should be migrated step by step.

To see an example, I have started to migrate a first test (see TestBooleanFilterProcessor).

If you are interested in working on one of the tests, please let us know and we will create an issue for each test and assign it to you.

List of classes

Hi, i want to work on this issue. TestBooleanCounterProcessor Could you assign this issue?

[tenthe]

Hi @nine03, Thank you for your interest. I have created an issue for you. Can you please comment under it so that I can assign it to you. If you have any questions, please let us know.

Cheers, Philipp

currently looking at TestSizeMeasureProcessor what are the values for these parameters @Parameterized.Parameter public String sizeUnit;

@Parameterized.Parameter(1) public int numOfBytes;

@Parameterized.Parameter(2) public double expectedSize;

@Parameterized.Parameter(3) public double allowableError;

[pambrocio]

Is it ok to use enums for this?? do we just need paremeterized inputs for org.apache.streampipes.processors.enricher.jvm.processor.sizemeasure.TestSizeMeasureProcessor#testSizeMeasureProcessor, (this is currently commented) . And Just make the test work???

[pambrocio]

would like to take on TestStringTimerProcessor

Here you go: https://github.com/apache/streampipes/issues/2764 🙂

[pambrocio]

please assign the remaining Test classes to me

[bossenti]

@pambrocio issues are created (see at the top) I can assign you once you wrote a comment there

[pambrocio]

Thanks @bossenti

Hey @pambrocio,

I just realized that some tests you have created PRs for are also part of https://github.com/apache/streampipes/pull/2375 (for reference: https://github.com/apache/streampipes/issues/2737, https://github.com/apache/streampipes/issues/2374). Would be great if we could align both endeavors to avoid extra work. Sorry for not pointing out earlier.

Hi @bossenti ,

Too bad i am almost done only one class left. Shall i continue?? this is the remaining class i have not migrated https://github.com/apache/streampipes/issues/2779 TestStringToStateProcessor

[pambrocio]

@tenthe

Any advice on this?

[pambrocio]

Hi @tenthe @bossenti @IsaakKrut,

the remaining classes have been migrated to Junit 5, Tell me what needs to be done to get my work merged to the main branch.

Thanks, Pambrocio

Hi @bossenti ,

Actually, I already mentioned that earlier: https://github.com/apache/streampipes/issues/2754#issuecomment-2069513982

Would you be interested to contribute to #2375 by adapting your migrated tests to the framework introduced there and help to improve it?

If not, we can merge the migrated tests that are not part of #2375. Otherwise, we would cause a lot of migration effort in #2375.

[pambrocio]

Hi @bossenti,

Would love to. Let me check the discussion

[bossenti]

@pambrocio would be great if you are willing to continue your work based on https://github.com/apache/streampipes/pull/2375#issuecomment-2083177795 🙂

@bossenti, I am quite unclerar on what code changes need to be implemented

[bossenti]

In #2375 we introduced a standardized approach how pipeline elements can (and should) be tested in future (https://github.com/apache/streampipes/pull/2375/files#diff-a8a7ae4c9654c4422ef00768c7887a92bfffc6e0726c1922531f57ae865ee531). The PR also contains some examples how this approach can be applied, e.g., https://github.com/apache/streampipes/pull/2375/files#diff-49a3517e7b83d0021ebf95c11e120d451297aff1c3eea3aab3f43dc8042cf9f0

So the task now is to update your PRs accordingly. This includes updating your branch with the recent changes in the dev branch and change the implementation of the tests so that they use the above described approach. As @tenthe already said, this approach is not fixed yet, so if you have any feedback, improvements we are happy to hear and address them or you can directly improve the proposed approach.

Does that make it clearer? 🙂
