Automated testing tools improve software development efficiency by streamlining the testing process, ensuring faster and more reliable software releases. These tools automate repetitive tasks such as regression, performance, and load testing, reducing the time required for manual testing. Improved accuracy is achieved by minimizing human error, while rapid feedback allows developers to quickly address issues and optimize code. Overall, automated testing enhances collaboration and maintains quality as part of a continuous integration/continuous deployment (CI/CD) process.
