Fixup Parameter form (float) and add testing gadget
Fixed up the support for float and properly handle enum (select) when the values are integer or floats.
Include a gadget to allow developers self test software releases while they are updating the software releases, it may allow the user handle few problems these days:
- Evaluate if the json schema correctly rendered flawlessly (since we don't exactly implemented the full scope yet)
- Evaluate if the saved data (after post) is correct (if certain data transformation from form to xml or json is output the expected value that the instance requires.
- Check for bugs that the parameter eventually have.
