What are the best practices to follow while performing JavaScript testing?
Hi Devan,
JavaScript testing is an important and crucial part of any JavaScript project. However, many times it’s overlooked because people tend to think that JavaScript doesn’t need testing because it runs in the browser. However, as applications and websites get more complex, JavaScript testing can become a nightmare without the right techniques and approaches for creating automated test scenarios.
Here are some of the best practices you must follow while performing JavaScript testing:
- Choose Behavioral Testing
- Decide When to Perform Unit Testing
- Follow Shift-Left Testing

- Make Test Automation Framework Portable
- Choose Logical Test Names
- Prefer BDD Approach
- No Need to Mock Everything
- Avoid Duplication in Implementation
