To learn software testing, start by understanding the basics of software development and testing principles. Familiarize yourself with different testing types (unit, integration, system, acceptance) and methodologies (Agile, Waterfall). Online courses (like Coursera Uncodemy or Udemy) and tutorials can provide structured learning. Practice by testing real applications or contributing to open-source projects. Learn tools like Selenium, JUnit, or Postman for automation and manual testing. Join forums or communities (like Stack Overflow) to discuss and solve problems. Finally, consider obtaining certifications (like ISTQB) to enhance your credibility and knowledge in the field.
