get pytest exit code from shell script

Question

I'm running pytest test from shell script. The relevant line in the script looks something like:

pytest pytest_tests --param=$my_param

According to pytest documentation, "Running pytest can result in six different exit codes" (0-5). My question is how can I get this exit code from the script? I tried something like

exit_code = pytest pytest_tests --param=$my_param
echo $exit_code

But I got this:

exit_code: command not found

How can I get it? Or is there a better way to get pytest results in the shell script?

Answer 1

After a command runs its exit code should be available via the $? variable. Try something like this:

pytest pytest_tests --param=$my_param
echo Pytest exited $?

This works in Bash, and should work in the regular sh Bourne shell and zsh as well.

If you need to assign this to another variable, use

my_var=$?

Note the lack of spaces.
