I’ve done a lot of testing, not skipping that, writing automated tests are a whole different thing however, it is not as straight forward and is very often skipped for a large amount of projects to be honest
Git was made to handle the sheer amount of commits and people contributing to the linux kernel, the first versions of linux is just Linus uploading the code to a FTP, git is just a tool for Linus to patch his local git tree in a fast way with all the patches he gets from different channels and manage a large public repository
Unlike Linus I’m not planning to be of control of a public development process for my software, so a VCS doesn’t make much sense in my opinion
Before git it was far from standard to use a source control system on small projects that weren’t about to be a public development process anyway, while it is a gold standard for source control today, I don’t think one have to use source control on every software project, like it used to be
