Code Review

A software quality assurance practice in which one or more developers systematically examine source code written by a colleague, looking for bugs, design issues, readability problems, and adherence to coding standards. Code reviews can be asynchronous (reviewing pull requests) or synchronous (walking through code together in real time). Synchronous code review in mixed-ability teams presents accessibility challenges because the reviewer and author need shared awareness of code locations, which collaboration tools typically convey through visual cues inaccessible to screen reader users.
