Unit test test_json_exporter doesn't work on Windows

[laurent-laporte-pro]

The unit test tests.test_jsonexporter.test_json_exporter doesn't work on Windows.

In the fragment bellow:

with NamedTemporaryFile(mode="w+") as ref:
    with NamedTemporaryFile(mode="w+") as gen:
        ref.write("\n".join(lines))
        exporter.write(root, gen)
        assert filecmp.cmp(ref.name, gen.name)

The filecmp.cmp function failed because the files are still opened.

The exception is:

Traceback (most recent call last):
  ...
  File "C:\Program Files\Python38\lib\filecmp.py", line 75, in _do_cmp
    with open(f1, 'rb') as fp1, open(f2, 'rb') as fp2:
PermissionError: [Errno 13] Permission denied: 'C:\\...\\AppData\\Local\\Temp\\tmpgr3lyx2m'

The solution is to close the files before comparison.
