Thread-topic: [EXTERNAL] Re: [jakarta.ee-spec.committee] Requirements for individual specification TCKs
Was this approach agreed upon by the specification committee? Is that even something the specification committee is responsible for deciding if it is the right approach? I admit that I may be missing some past context where a tactical decision was made to
expediate an EE 10 release. Perhaps it is the best we can do for EE 10 with the timeline and the number of developers available to improve the situation.
Instead of focusing on what we can and cannot do for EE 10 I want to circle back to the potential proposal I laid out with this thread. Is there agreement that we have a gap in the current approach being taken? Would having requirements in place that I suggest
help close the TCK gap to ensure that the EE platform and other profiles compatible implementations do indeed function properly for all aspects of the specification?

What we are doing for EE10 is to duplicate tests that exercise the
expected integration points that are most likely needed in the various EE containers. No one was willing to make test reuse a blocking requirement for EE10, so that is the best

> 1. Run the standalone SE based TCK against the implementation jar. The JSONP TCK docs describe how to do this by setting the GAV maven coordinates of the vendor implementation.
In this case, the tests are SE only and they can't be executed in an EE container. How can we ensure to the customers that JSON-P behaves as specified without tests backed up in that context?
e.g. a snake swims well in cold water (e.g. SE). It might not function well in warm water (e.g. EE).
I totally agree with what David said: This is why we run the same test several times, once as a Servlet, again as a JSP, again as an EJB, etc. To go from that to the extreme of it not being testable in a container at all is too far of a departure IMO.
I think it is ok to run some tests in SE container, but these tests should also be executable in EE if the functionalities are applicable to EE.
Taking JSONP as an example, for EE10 the discussion we had was that the requirements would be: 1. Run the standalone
SE based TCK against the implementation jar. The JSONP TCK docs describe how to do this by setting the GAV maven coordinates

2. The platform TCK would keep the integration only tests to validate basic container level integration.
For EE 10 we have several new individual TCKs. I would like to understand if we established any general policies for how such TCKs are executed. I'm asking for a general
discussion about such a policy. But if it helps to have some examples I am referring to the TCKs for the individual specifications JSON Binding, JSON Processing and XML Binding. My understanding of these three individual TCKs is that they are only able to
be run directly against Java SE.
Is there a specific individual Jakarta EE specification TCK that you are referring to? Perhaps one of the new
for EE 10 TCKs? Scott On 4/5/22 10:24 AM, Thomas Watson wrote:

Hi all,
It is not clear that the specification committee has discussed and decided on the requirements for individual specification TCK execution (aka standalone TCK). Recent discussions about individual specification TCKs have identified an exposure for a platform
implementation to claim compliance for individual specifications that are included in the platform, web profile or core profile. A TCK must be executable within the context of the profile it is included in: platform, web profile or core profile. Otherwise,
there is no confirmation that the compliant platform, web profile or core profile implementation functions properly with respect to the individual specification TCK.
Some individual specification TCK teams have indicated the desire to develop TCKs that are only executable outside of a profile implementation and only run directly on Java SE. It is acceptable for specification projects to develop a TCK that can run
directly on Java SE. It is not acceptable for that complete TCK to only be executable directly on Java SE.
A TCK can have three types of tests:
Tests that only apply when running outside of a platform (or profile), such as on Java SE, to test behavior defined by the specification for that mode of execution.
Tests that only apply when running in a platform (or profile) to test behavior defined by the specification for that mode of execution.
Tests that apply to the behavior defined by the specification for all modes of execution.
The tests of type 2 and 3 must be able to be executed in the context of the profile they are included in: platform, web profile or core profile.
We want to discuss proposing the following requirements for individual specification TCKs within the specification committee:
The individual specification TCK must provide a profile-ready mechanism for running the required TCK tests (types 2 and 3) in the profiles they are included in: platform, web profile or core profile. Type 1 tests must be excluded and not required to be
executed.
The individual specification TCK must provide a mechanism for running the required TCK tests (types 1 and 3) outside the context of a platform or profile such as on Java SE. Type 2 tests must be excluded and not run.
It is important that type 3 tests be run in compatible implementations of the profiles to validate the individual specification implementation functions properly in the profile implementation: platform, web profile or core profile.
Note that we avoided using the term "standalone TCK" because to some the term "standalone" means TCKs that run outside of any platform or profile container.
