[New-bugs-announce] [issue30868] IDLE: Improve configuration tests with mock Save.

[Terry J. Reedy]

New submission from Terry J. Reedy:

When writing tests for config and configdialog, I blocked the user configs from hitting the filesystem by passing '' as the file name.  This disables the Save function.  To know that Save is called, a mock is needed.  To know what would have been written to disk, the mock could write to a StringIO.  Since there are 4 files and 4 config parsers, there are 4 save functions.  I would mock each separately so it can be determined that the right one was called.  I plan to create a specialized version of idle_mock.Func with a simplified version of Save's body in the __call__ method.
