[BUG] `python-flask` incorrect boolean literal in unit tests.

Created by: edupo

Description

Given a model where a property is declared with type bool and using the openapi-generator-cli version 5.1.0 and the generator python-flask the generated test body values reads as follows:

body = {
  "boolean_property": true
}

Being true, not the right literal for expressing a True value in python (Note the capital T).

openapi-generator version

5.1.0

Generation Details

Generator python-flask

Suggest a fix

There must be an issue with the defined boolean values in the generator templates.
