Check for what group of tests must be generated with TestGen

[alexgarzao]

Some tests already exist, but can be generated by TestGen:

• Unit tests to validate operations
• Unit tests to validate operation x type

Some tests do not exist at this time and can be generated by TestGen:

• Unit tests to validate "condition table"
• Parser tests (parser_tests.go)

Expected result:

• Define what group of tests is worth generating with TestGen
• Create sub-tasks with these groups os tests
