This is testing apt, not dpkg. So the file name and the testcases/class 
names should be renamed accoridngly.

That's a good start, but apt can do more, right? Play with its various 
utilities (apt-get, apt-cache, etc.) on the command line. What kind of 
features it has? Can those be tested automatically? Should they be tested?

Also, before you do advanced package installation/removal, it's good to 
run a few sanity checks. Check that apt is able to print a help message 
without crashing, that it can list installed and available packages and 
so on. You can look at dnf test cases for examples.

And same applies to opkg test cases as well.
