Code Quality: Automated Testing
What are the three main components of Behavior Driven Development?
Interview Response: The three main components of behavior-driven development include testing, documentation, and clear examples.
- Karma's primary purpose is to provide developers with a productive testing environment. The environment is one in which they do not have to set up a plethora of setups but rather one in which developers can write code and receive a quick response from their tests.
- Jest delivers a zero-configuration testing experience for developers. There is no need for any additional setup configuration or libraries, and it is also easy to learn for most developers. Jest is part of the Facebook open-source project group.
- AVA is a Node.js test runner with a straightforward API, thorough error output, support for future language features, and process isolation that allows you to create with confidence.
What is the difference between behavior development and test drive development?
Interview Response: Behavior Driven Development (BDD) aims to evaluate an application’s behavior from the end user’s perspective. In contrast, Test Driven Development (TDD) focuses on testing smaller parts of functionality in isolation.
What Is the primary purpose/benefit of unit testing?
Interview Response: With good unit tests, developers may refactor without worry, and that is, they can maintain and extend the application considerably more quickly. Because the bulk of an application's cost is in maintenance and extension, assisting in reducing such expenses can considerably influence an application's total cost of ownership (TCO).
