[DMN 1.5] Add tests for equality operators in positive unary tests to the TCK suite

[kbowers-ibm]

Adding tests for positive unary tests.

[baldimir]

Thanks Kennedy. If the group agree to merge this, it needs to be done after the current master is branched for DMN 1.4.

@dmn-tck/contributors please review

[SimonRinguette]

Tested on the Trisotech engine and it works.

Not sure why this would go to dmn-tck:dmn1.5 instead of master. because its DMN 1.3

[opatrascoiu]

I think is because support for the operators = and != in simple positive unary test (before endpoints) was added in DMN 1.5 https://issues.omg.org/browse/DMN15-108

[SimonRinguette]

Make sense

[dsntk]

There are already tests for 1131 in main. Test case directory and file names have to be adjusted. Otherwise existing tests will be overridden.

[baldimir]

I will fix it. Thanks for noticing this.

[opatrascoiu]

The tests look good to me apart from the filename (1131 is already taken by another test case)

[StrayAlien]

I think these cases are already covered in "0072 feel in tests".

[opatrascoiu]

@StrayAlien The == and != are not covered as they were introduced in DMN 1.5. How about we add tests for == and != in 0072 to keep all trhe in tests in one place?

[StrayAlien]

Thanks @opatrascoiu . That what this PR is for: #668. It asserts on those new operators for FEEL types - except list because this is still uncertain I think. (as well as uncommenting some null tests we had in there to see if they now are valid)

[opatrascoiu]

I checked the tests in PR #668 and they cover the ones here.

@kbowers-ibm @baldimir I think it makes sense to close this MR and focus the review on the one mentioned by @StrayAlien as it groups the test cases for unary tests in an already existing test file.
