Automated testing

[mokiros]

What I have in mind:

• Testing scripts will pass strings to the terminal, then compare the screen buffer to the expected one
• Strings for testing can be obtained by recording stdout of programs and shells while manually using them
• Since a reference buffer is needed, this implies that when a test is first introduced, the feature that is being tested is implemented correctly, meaning:
• The tests are not meant to develop new features (unless an externally obtained or manually crafted reference buffer is used), but rather to prevent bugs and inaccuracies in existing features
