[PATCH 0/3] RFC: Package testing

[PATCH 0/3] RFC: Package testing

[Björn Stenberg]

Hi.

This is a first set of patches implementing the package testing concept
I proposed in 
https://lists.yoctoproject.org/pipermail/yocto/2012-June/009443.html

In summary, the proposal creates a new package group called -ptest that
contains the test suites included with many source packages, compiled to
run on target.

Packaging the test suites sometimes requires patching makefiles to allow
test tools to be built on host but ran on target. And it sometimes
requires patching and/or translation of the test output to produce a
generic output format that can be automatically parsed. I have included
an example patch for bash that does just that.

I have also included "ptest-runnner", a simple script to find and run
all installed ptests.


Björn Stenberg (3):
  Add -ptest package group
  New recipe: ptest-runner
  Enabled bash-ptest

[PATCH 1/3] Add -ptest package group

[Björn Stenberg]

This patch creates a new package group -ptest to contain the tests for
each package.

Is this really what you want? Surely the tests for a particular piece of 
software are mostly independent of those of its dependencies?

Rest of it looks good.

What is this generic output format?  From your patch to bash I suspect
it's at least inspired by the automake "make check" output.

FWIW, this is what "make check" on librest (the first package I had to
hand) gives:

Would this test suite just work if packaged as ptests?

Yes, I used the automake-style "(PASS|FAIL): <testcase>" format.

In addition to that, before/after each package test suite is started, "(BEGIN|END): <package>" is printed. So a typical output looks like this (paraphrased):

BEGIN: bash
PASS: test1
FAIL: test2
PASS: test3
END: bash
BEGIN: busybox
PASS: test1
FAIL: test2
END: busybox

You're right, that change is not necessary. I misunderstood the purpose of DEPCHAIN_POST.

I think filedeps could be useful in this case, autodetecting any
dependencies scripts in the -ptest package could have for example so I'd
not do the above.

ditto, we want to detect shlib dependencies.

I also suspect the above two hunks are not needed since ptest won't use
depchains.

Would a ptest.bbclass containing the above make more sense? How
widespread do we think these tests will be?

Also these patches are against OE-Core so need to go to the
openembedded-code mailing list.

I do like the idea of better testing of packages and this is a good
start though. My biggest worry is the overhead of the patches to
software to enable the tests. Are you planning to engage the upstreams
and see if we can get them to accept the patches? I have to be very
cautious of anything which would "strangle" us with patch
overhead/overload and stop us being unable to update recipes.

Cheers,

Richard

As it stands, I can bet on upstream saying "no" to this for good reason.
A better concept might be to introduce $(CC_FOR_TEST) which could
default to CC_FOR_BUILD. This would let us do what you're thinking here
yet keep upstream happy too.

Just thinking out loud really...

Cheers,

Richard

Thanks for proposing and getting the initial implementation started, 
this has been something we have been thinking about for a while, great 
to have the things like this become reality!

When introducing new patches, please follow the guidelines for patches 
and commit message:

http://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines

I know this is still and RFC, but your commits themselves also need 
Signed-off-by:

One thing that we have discussed a couple of times, but no real outcome 
yet is to make the building of tests conditional so as more recipes are 
enabled with this kind of change, we don't extend the default build time 
too long.

What's been discussed is using DISTRO_FEATURE to test first.

Thoughts?

Re: [PATCH 1/3] Add -ptest package group

Most source packages include some form of test suite that we want to make into a -ptest package. I would guesstimate the number to be somewhere between the number of -dbg and the number of -dev packages. This is why I felt it made sense to add the handling of -ptest side-by-side with the handling of -dev and -dbg.

Upstreaming is absolutely the idea, both for the benefit of the entire ecosystem and of course to reduce the number of patches.

However I won't downplay the effort required to get hundreds of upstream projects to agree on a common concept for test cross compilation and result formatting.

I see two main options: Implement first or discuss first.

a) Implement first: We design and implement a good system for yocto/oe and then, once it has proven itself, engage the larger open source community with our already tested concept.

Pro: It's easier to discuss an already working system
Con: We'll have to manage patches for all packages until agreement

b) Discuss first: We invite the whole open source community to discuss and try to agree on how to handle cross-compiled test cases and test result formatting before we implement anything.

Pro: No increased patch load until agreement
Con: No result until agreement, which could potentially take a long time

My suggestion is a). I'm open for any and all suggestions that would make the patch load easier to manage.

I'll update the patches with the feedback I've got and post them to oe-core for further discussion.

Thanks.
