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_misc.yml
  test_addition:
    - a: 1
      b: 2
      c: 3
  
    - a: 2
      b: 4
      c: 6
  

• Decorate the corresponding test functions with @parametrize_from_file:

  # test_misc.py
  import parametrize_from_file
  
  @parametrize_from_file
  def test_addition(a, b, c):
      assert a + b == c
  

• Run pytest as usual:

  $ pytest
