Code reviews are crucial for high-quality code, and testing skills are essential for fullstack developers to write robust tests, focusing on individual tests, test coverage, complexity, redundancy, and error handling, with advanced topics like property-based testing, code analysis tools, and behavior-driven development.
Explains how Behavior-Driven Development (BDD) with Cucumber lets fullstack developers turn requirements into executable, plain-language specs (Gherkin) that align stakeholders, speed feedback, boost coverage, and serve as living documentation; shares best practices and a checkout example, showing how BDD cuts defects and rework while improving quality and onboarding.
