Testing functions that use $0

[jdholtz]

Hello, I just started implementing Bats tests for my project. I have one function that relies on using $0 when testing (example below). How would I test this function, as $0 when bats calls the function is bats-exec-test? Or would it be best to refactor my function to not rely on $0? I've tried doing BASH_ARGV0=... run <func>, but that doesn't work. Thanks!

function special() {
    local var="${0##*/}"
    if [[ "$(basename "$var")" == "script1" ]]; then
        echo "Executing under script 1"
    else
        echo "Not executing under script 1
    fi
}
