Respectfully I disagree. I’ve found that ‘talking about doing it’ will cause problems if you aren’t able to do it and hold schedule with everything else. From personal experience, for parent post, I’ve found it’s been best to implement what you can for unit tests and grow it yourself slowly or at whatever pace you are comfortable with, but set the bar high for yourself, beat it, and then maybe try to get others on board. This only holds if there is no mentor you could talk into helping you. Just personal experience. :-/ If the culture doesn’t encourage them now, announcing you will be doing it might only hinder the effort.
