[DISCUSSION] Committing Minilang test patches under OFBIZ-1463
Hi All,
We started a discussion in OFBIZ-1463 about committing or not the Minilang test patches.
There are already few mixed opinions there (Michael, Aditya, Suraj and I).
Before voting I'd like to know if we can come to a consensus.
Please read in OFBIZ-1463 and come back with your opinion.
I have just changed mine because I believe using the tests as soon they are reading is a good thing.
Waiting would be a waste of not only work done but also time for code safety. We can still move them to Groovy later, it's not more work, I guess it's
even less.
Jacques

Hello everyone,
I am inclined with Jacques opinion (Initially what we proposed to commit
those patches into the repo) here, on the flip side I would like to mention
that we are gradually working on moving these XML's to groovy.
So whatever we conclude, I am up for it.

BTW, thinking about it, I agree it does not help to fix wrong tests.

I see your point, you kinda expect people having created Minilang test patches to convert them themselves. Not sure that will we work.
If I get empathic (something I easily do when reviewing) I can understand the frustration of those people.
They create a patch before the decision is made and bam, it's no good :/
So it does not help to "put the blame" (OK I emphasise a bit here ;)) on them
Also we can't even rely on an expectation they will do the work. Some people come and go...
Anyway at some point someone will have to do it
And at least, I believe it's better to inspire from those patches than to start anew

Oh that! I never look at integration test logs, it's impossible indeed.
I simply look at the result of the tests where the error logs are.

Makes totally sense, unfortunately with 1300+ tests [1] I don't expect that to happen soon

Thanks for expression your opinion, that helps!
After 3 days, only people against expressed their opinions, so I think the discussion is closed.

I was not saying either solution is more work, I was just acknowledging
that right now, nobody wants to do the work of migration for those
tests.

> directly write test in Groovy?
Yes I expect people having proposed the patches to update their patches
with the groovy migration before applying those patches.

The problem I see is that if the people proposing the patches are not
willing to do the migration work right now, I see no reason why they
would want to do it afterwards when there will be no incentives to do
so.
If we apply those patches as they are, then the rest of us will
eventually have to understand/maintain/debug them when they fail. Given
the current sad state of OFBiz integration tests we cannot afford to let
more “stuff to be cleaned up later” enter the codebase.
To explain my hard feeling regarding OFBiz integration tests. I find
them really hard to understand/debug due to the following points:
- Logs are unreadable! I mean understanding which test has failed is
already an endeavour.
- The global nature of the data loaded during the tests makes things
brittle. We saw a lot of that in previous weeks where tests were
succeding when having both the framework and the plugins but failing
when having only the framework.
- People tend to be confused between integration and unit tests,
resulting in integration tests written in an atomic way which is not a
good thing. For example for testing services manipulating an
hypothetical entity ‘foo’, we would have a ‘testCreateFooService’ that
adds some stuff in the database and ‘testUpdateFooService’ that
retrieve the stuff added by the other. This is bad since it
introduces a order dependency between those tests. Instead of small
integration tests we should have bigger independant ones following a
scenario with multiple asserts.
Sorry for being long but I wanted to make clear that this is a real
issue.

Wait Mathieu,
Could you explain why it would me more work to migrate from a patch than to migrate from code already in the repo?
Maybe you mean that migrating is a burden anyway, and it's better to directly write test in Groovy?
Then I see no problems doing that and having already Minilang tests present. We "just have" to drop Minilang tests when Groovy ones are ready.
What I'm missing?
Thanks

If it's less work, then why people interested in having those patches
applied has not migrate those tests yet? :-)
Having contributed to the migration of the “quoteTests” I know for a
fact that this is painful work. Applying those patches in their current
state would simply mean putting the burden on someone else to do the
work. So I am strongly opposed to committing thoses patches before the
tests are migrated.
As far as I am concerned, if people want stuff to be committed then they
have to do their homework first.

As a general rule, minilang adds to the technical debt of this project. It
is hard to understand or maintain even simple constructs in minilang.
To generalize this concept... Patch != Good patch. So I recommend that
everything goes through the funnel of good old reviews. Good code has no
shortcuts, it is blood sweat and tears both for the provider and the
reviewer of patches.

I explained my POV in the Jira [1].
Why not encourage the contributors to move their minilang tests to
Groovy code? I can see that this has already been done, e.g. here [2]
(thanks everyone involved!).
I'm sure that the remaining patches will get converted soon, no need to
choose the "easy way" and commit the minilang versions.
If we will allow more minilang commits, we will always have the
discussion and won't ever get rid of it.
Thanks,
Michael

-1 to introduce more minilang code to the codebase. New code should be provided in either Java or Groovy code.
