Currently we're not doing any code reviews and we have effectively zero unit tests (we have some but they are never run by anyone else other than myself) and there's no coding standards for style and we're dealing with C#, Python, JavaScript and HTML/CSS.
We're starting to use branches and pull requests in github with very quick code reviews and no unit tests associated with the code.
The manager explicitly said that cutting corners on quality is okay, however half of the bugs we're fixing are regressions and the other half is basically re-work of low quality contractor work.
Is there a nice way to introduce a culture of quality into an environment like this?
