Automated tests for bash completion

[sio]

It would be nice to have automated tests for this completion script. Python offers tools to do that (pexpect).

See how others do it:

• https://github.com/scop/bash-completion/blob/master/doc/testing.txt
• https://github.com/scop/bash-completion/blob/master/test/t/conftest.py

Unfortunately, pexpect does not work on Windows due to relying on ptys.

Work is being done in tests branch. This is what needs to be tested:

• [x] Simple completion - single result
• [x] Simple completion - many results
• [x] Partial completion - single result
• [x] Partial completion - many results
• [x] Escaping special characters
• [x] Quotes ' and "
• [x] Tilde expansion for home (~, ~username)
• [x] Tilde expansion for pushd (~1, ~2)
• [x] Case insensitive expansion
• [x] Tab cycles to the beginning after the last completion variant
• [x] Shift+Tab cycles back
• [x] Issue #10
• [x] Environment must stay clean after importing the file (before executing _bcpp)
• [x] Cooperation with _filedir from @scop package

The task was too interesting to delay :) I started implementing automated tests for bash-complete-partial-path in tests.

Top post will be updated with progress checklist.

A lot of work had been merged to master. That includes:

• Base classes and fixtures for writing tests
• Some automated tests covering essential functionality
• Documentation for automated tests
• CI integration

This issue will remain open to track progress for implementing the rest of test suite.

All listed test cases are implemented, changes have been merged to master. 🎉
