pip prod(deps): update pytest requirement from <6.0,>=3.6 to >=3.6,<7.0

[dependabot]

Updates the requirements on pytest to permit the latest version.

Release notes

Sourced from pytest's releases.

6.0.0

pytest 6.0.0 (2020-07-28)

(Please see the full set of changes for this release also in the 6.0.0rc1 notes below)

Breaking Changes

• #5584: PytestDeprecationWarning are now errors by default.

  Following our plan to remove deprecated features with as little disruption as possible, all warnings of type PytestDeprecationWarning now generate errors instead of warning messages.

  The affected features will be effectively removed in pytest 6.1, so please consult the Deprecations and Removals section in the docs for directions on how to update existing code.

  In the pytest 6.0.X series, it is possible to change the errors back into warnings as a stopgap measure by adding this to your pytest.ini file:

  [pytest]
  filterwarnings =
      ignore::pytest.PytestDeprecationWarning
  

  But this will stop working when pytest 6.1 is released.

  If you have concerns about the removal of a specific feature, please add a comment to #5584.

• #7472: The exec_() and is_true() methods of _pytest._code.Frame have been removed.

Features

• #7464: Added support for NO_COLOR and FORCE_COLOR environment variables to control colored output.

Improvements

• #7467: --log-file CLI option and log_file ini marker now create subdirectories if needed.
• #7489: The pytest.raises function has a clearer error message when match equals the obtained string but is not a regex match. In this case it is suggested to escape the regex.

Bug Fixes

• #7392: Fix the reported location of tests skipped with @pytest.mark.skip when --runxfail is used.
