Test Coverage Summary

Tests for Pydantic V2 include:

• Basic alias functionality Form(alias=...) + the same for form model
• Validation alias functionality Form(validation_alias=...) + the same for form model
• Combined aliases Form(alias=..., validation_alias=...) + the same for form model
• Workaround Form(alias=X, validation_alias=X)

Each of test cases (except workaround) covers different field types:

• Required str field
• Optional str field
• list field
• Optional list field

Each of test cases covers different parameter types:

• Form field
• Form field declared as model (think about adding tests for alias_generator, populate_by_name, alias_priority, alias_choices)
• File field
• File field declared as model (TODO: add tests)
• Body field (TODO: add tests)
• Body field declared as model (TODO: add tests)

For each type of parameter declaration, the following is checked:

• Send parameter by name
• Send parameter by alias
• Send parameter by validation_alias (if specified)
• Generate openapi schema

Tests for Pydantic V1

Tests for Pydantic V1 duplicate tests for V2, excluding all tests with validation_alias (it's not implmented for V1 and I don't think we need to add this)

Current situation with alias support

Currently tests expose several issues with Pydantic V2:

• Single fields (not model):
  • alias - for Form\File fields works partially - isn't reflected in schema
  • validation_alias- for Form\File fields is reflected in schema, but doesn't work
  • optlional list of files - fails with TypeError
• Fields declared as model:
  • Pydantic Models with validation_alias for List Fields fails due to some bug ("Input should be a valid list","input":"456")

Currently tests expose 1 issue with Pydantic V1:

• Schema for all optional fields is invalid(?) (just string instead of anyOf) - TODO: investigate
