Software development has become an integral part of our daily lives. With the ever-increasing complexity of software applications, testing has become a crucial part of the development process. Testing ensures the software meets the desired quality standards and performs as expected. However, manual testing can be time-consuming, repetitive, and prone to human errors, which is why automation testing has become increasingly popular. Katalon Studio is an all-in-one automation testing tool that helps automate various testing types, including API testing, web testing, mobile testing, and desktop testing.
