[issue44503] Hide __enter__ calls in mock_open

[Pierre Ossman]

New submission from Pierre Ossman :

I'd like to write this test case:

  with patch('builtins.open') as pyopen:
mock_open(pyopen, read_data="foo")
run()
pyopen.assert_has_calls([call("filename", "wt"),
 call().write("gazonk"),
 call().close()])

and I shouldn't have to care if the code is written like this:

  def run():
f = open("filename", "wt")
try:
  write("gazonk")
finally:
  f.close()

or like this:

  def run():
with open("filename", "wt") as f:
  write("gazonk")
