Test run files

[luizaandrade]

Add do-files used for testing the commands to GitHub, so we can always use the same do-file to test all options of the commands every time a new change is made.

There will be one test run file for each command. Each test run file will run the command with different options and should include special cases that the command should be able to handle. Whenever anyone makes an update to a command they should make sure that this test run file runs without error before submitting a PR to make sure the new edits did not brake anything.

Everyone are encouraged to add special cases that are more likely to cause errors.
