Bats is intended for testing shell scripts. It is simple to use and has a lot of features. In this post.
I have found out that Bats is a great tool for testing other types of executables as well, such as:
- Go CLI applications
- Perl scripts
I found this nice tutorial on how to get started with Bats:
This is the vary basic use I am currently working with for testing a Perl script.
My normal Perl unit-tests are located in the t/ directory. In addition I have created a directory named test/ which contains the Bats test scripts.
In that directory I have a file named test.bats, with the following contents (the names have been simplified for readability):
@test "can run our script with --help option" {
carton exec -- ./script/perl-script.pl --help
}
@test "can run our script without options" {
carton exec -- ./script/perl-script.pl
}
