This month I paid more attention to tools and their providers.
I have a good impression of Applitools, Saucelab, and Browserstack. They offer more than a tool. That is invaluable for their users.
My go to advice for testers learning test automation is the Test Automation University. A lot of knowledge and experience are offered for free.
During my first months of test automation I had problems with automated tests. It would be great to have some FAQ in place. For example, my test passed 80% of the time without changing any code.
Quite a few of of them (SmartBear, Perfecto, TestRail) have free webinars, blog content, testing related events. QA Touch had some really cool community based activates recently: Global Testers Day 2021 - QA Touch
Different kinds of free content, giveaways, hackathons, etc. For me another nice useful thing are the email newsletters, TestProject has a nice one:
I have really enjoyed using Slack and Discord to connect with folks using the same tools. Cucumber and Playwright communities come to mind first. I have had a number of constructive conversations in Cucumber channel specifically.
Most maintainers are pretty cool when they hear about how you are using their tool to solve problems. Then they seem to open up a bit more after that.
I really like this approach, the Slack one, because of the climate of the world. It allows easy connection with the people that matter to a tool without having to go to conferences or meetups.
