Write a json report file
------------------------

.. versionadded: 1.6

You can instruct tox to write a json-report file via:

.. code-block:: shell

    tox --result-json=PATH

This will create a json-formatted result file using this schema:

.. code-block:: json

    {
      "testenvs": {
        "py27": {
          "python": {
