One tool to generate all test cases

[alexgarzao]

At this time, two generators were identified:

• to generate benchmark tests between ValidGen and GoValidator
• to generate end-to-end tests
  • to validate ValidGen with integer types
  • to validate ValidGen with float types
  • to validate all possible use cases in ValidGen (all validations x all types)

Beyond that, some new generators could be created:

• Unit tests to validate the "buildValidationCode" function

And, for all cases, valid scenarios and invalid scenarios could be generated.

After that, some refactoring could be done:

• Remove duplicated tests
• Some helpers (like HelperFromNormalizedToBasicTypes) could be moved to the new generator package

To be possible to generate all these tests, this new generator must have a table with:

• all valid operations
• all invalid operations
• all valid go types
• all valid operation x type
• valid input cases for each operation x type
• invalid input cases for each operation x type
