test ...

That way all of the commands in your tests will succeed or fail. If
|
||||
you must ignore the return value of something (e.g., the return
|
||||
after unsetting a variable that was already unset is unportable) it's
|
||||
best to indicate so explicitly with a semicolon:
|
||||
|
||||
unset HLAGH;
|
||||
git merge hla &&
|
||||
git push gh &&
|
||||
test ...
|
||||
you must ignore the return value of something, consider using a
|
||||
helper function (e.g. use sane_unset instead of unset, in order
|
||||
to avoid unportable return value for unsetting a variable that was
|
||||
already unset), or prepending the command with test_might_fail or
|
||||
test_must_fail.
|
||||
|
||||
- Check the test coverage for your tests. See the "Test coverage"
|
||||
below.
