Parametrize From File

Parametrize From File is a library for reading unit test parameters from config files. It works with the pytest framework. Below is the basic workflow that this package enables:

• Write test cases in a JSON, YAML, TOML, or NestedText file:

  # test_camelot.yml
  test_str_find:
  - str: sir lancelot
    sub: lance
    loc: 4
  
  - str: sir robin
    sub: brave
    loc: -1

• Decorate the corresponding test functions with @parametrize_from_file:

  # test_camelot.py
  import parametrize_from_file
  
  @parametrize_from_file
  def test_str_find(str, sub, loc):
      assert str.find(sub) == loc

• Run pytest as usual:
