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.
