Can you add a note here that also says which target I should be trying to build
if I want to make/run the tests (e.g. "See cast_test_lists below")? Or maybe
switch the order and put the buildable/runnable target first?

[slan, 2015/10/01 20:08:03]

Done.

+cast_test_group("cast_tests") {

[alokp, 2015/10/01 13:13:46]

If both of these templates are only being used once, why do you need a template?
Do you expect to use them in internal code as well?

[slan, 2015/10/01 14:08:56]

Exactly. There will be 2 cast_test_group()s: one for external tests and one for
internal tests. And while there will only be one cast_group_test_list, that
object requires knowledge of the implicit targets created for each
cast_test_group, so it makes sense to define it in this .gni. Here is the
internal CL for reference:

https://eureka-internal-review.git.corp.google.com/#/c/39533/

[mbjorge, 2015/10/01 17:11:40]

Is this target supposed to be //content/test:content_unittests?

[slan, 2015/10/01 20:08:03]

Yes, added a mechanism to ensure that the target names are valid.

I like the filters being here. I don't think it would make sense to put them
elsewhere.

Agreed.

maybe copy over the "#else x86 or android" comment, to make it more clear, since
the matching if() is kind of far away? Or, even better make it into an 'else if'
with an explicit condition

[mbjorge, 2015/10/01 17:11:40]

the name 'internal_unittests' looks more like a test() target and not a
test_group like 'cast_tests'. maybe cast_internal_tests or internal_cast_tests
for consistency? Or change cast_tests to be cast_unittests?

[slan, 2015/10/01 20:08:03]

Done.
