Once you’ve written code, you will need to test it with code review tools to identify potential issues. Your employer may expect you to perform a range of rests on your code, including functionality testing, static code testing, unit testing, and single-user performance testing. Pass-around testing is a way development teams ask for feedback by emailing their colleagues their code before deployment.
