I want to be able to create a number of users with different profiles to use with our automated testing. These will be created in sandboxes following refreshes, and in scratch orgs as part of our Continous Integration practices. They will never exist in Prod. I have found the Data Loader option but that does not give me useable users, I would still need to log into Salesforce and trigger the email process that asks the user for a password, then somehow capture the email and trigger the link to enter the new password. Not impossible via automation but really painful and brittle, hence a need to be able to do it programmatically...
