`process.env.profile` is the string "undefined" when no --profile is specified
What are you trying to achieve?
I wanted to control what browser is run using --profile
and fallback to chrome if --profile
was not provided.
What do you get instead?
I got errors like "Error: Cannot find the browser. "undefined:headless" is neither a known browser alias, nor a path to an executable file.".
I tried debugging by putting console.log(process.env.profile, typeof process.env.profile);
in my codecept.conf.js and got "undefined string".
Details

console.log(process.env.profile, typeof process.env.profile);
setHeadlessWhen(process.env.CI);
setBrowser(process.env.profile || 'chrome');
setTestHost(process.env.TEST_HOST);
exports.config = {

Investigation
I did a bit of debugging and it looks like the issue is the way that the run command (and other commands) set the profile.

It appears that when you assign to process.env.profile
Node stringifies the value. So if options.profile
is undefined then it gets stringified to "undefined" instead of resulting in the env not being set.
