This has multiple advantages. For one, we can simplify our code, as we
can use globals like os.Stdout and flagsets directly.
It will also be easier to write parallel tests which will run faster, as
each testscript runs concurrently.
While at it, start using $HOME if set, as that is often better than
blindly relying on the current user's home directory via cgo.
Go 1.11 and 1.12 add os.UserCacheDir and os.UserHomeDir respectively, so
soon enough we'll be able to replace most of basedir with those.
Finally, stop having the tests require on the f-droid.org repository to
work. Committing under 2MB of data is plenty to get the files we need in
a static local http server, which makes the tests much faster and not
depend on an internet connection.
Follow-up commits will finish porting the rest of the tests.
This way, users can simply do:
go get mvdan.cc/fdroidcl
Instead of the repetitive:
go get mvdan.cc/fdroidcl/cmd/fdroidcl
The cmd/... pattern only makes sense if the repository has many
commands, or if the name of the repository and command don't match.
Neither is the case here.
This way, we avoid linking an executable, and running the tests is also
faster. This shaves the test time by half, from ~9s to ~4s.
This also means we can use tooling better. For example, the cover tool
now works properly, reporting a coverage of nearly 60%.
When trying to uninstall an app that is not installed adb prints just
"Failure". This causes output parsing to fail and results in "panic:
runtime error: index out of range" in adb.getFailureCode().
Check whether an app is installed first and print an appropriate message
if it's not.
