add covering tests for abq test and abq work

[michaelglass]

add golden tests recording

• stdout
• stderr
• and status code

for

• abq test
• and abq work

with

• a group of successful tests
• and a group of failing tests
  to the matrix.

should we use a testing framework here?

In #47 are we separating stdout and stderr and checking the status code? It may not be necessary, but I thought it sounded like a good idea.
