gh-151678: Add tests for tkinter font, image, variable, Misc and Wm methods by serhiy-storchaka · Pull Request #151751 · python/cpython · GitHub

Fill the remaining gaps in the already-thorough font, image, variable, Misc and Wm tests:

font: copy(), the config alias of configure, the displayof argument of measure and metrics, and the errors raised for invalid options and a wrong number of arguments;
image: the cget method and the config alias, and the errors raised by transparency_get and transparency_set;
variable: that initialize is an alias of set and the deprecated trace is an alias of trace_variable;
Misc: tk_focusNext, tk_focusPrev, tk_strictMotif, tk_bisque and option_readfile;
Wm: wm_iconphoto.

Issue: Improve test coverage of tkinter #151678

Note: switching to '4330f46759c6e867c66c6b99a35093cf11cb8095'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
