Well, how about just doing your work first? If you like writing tests, do it. If you're allowed to commit them, OK. If it is good, others will follow. But don't talk to much about it and beware forcing others to do their work like you do. If there is something like code review meetings, you may show it to others. If there is no SonarQube or infrastructure, establish it e.g. in Docker on your system. Have a plan in mind, how to transfer it to the company infrastructure, but don't force anyone to do so. Just if someone asks you. You have an opportunity here to integrate YOUR personal way of testing and spreading the knowledge. Have faith that good things will prevail. Give it a year...
