Common questions about the QA course

Not to get started. Manual testing does not require programming and the Software Tester QA Course starts from zero. To automate tests it helps to learn a language, which is why there are JavaScript, TypeScript and Python courses designed for testers.
Start with the Curso de Software Tester QA, with 74 lessons and a price of 150 €. If you would rather try first, there are free introductory courses on API testing, Postman, Git and Playwright.
Yes. Most of the catalogue is free: Playwright, Selenium with Python, Cypress, Postman, API testing, Git, and JavaScript and Python for testers. Only some longer programs, like the Software Tester QA Course, are paid.
Manual QA designs and runs tests by hand to find defects. QA automation writes code (with tools such as Playwright, Selenium or Cypress) that runs those tests in a repeatable way. The usual path is to start with manual testing and add automation.
The platform issues downloadable certificates that can be verified online with a verification code, when you complete the courses that include one.
With two live workshops: Automation Portfolio Builder (5 sessions to build 5 automation repositories) and Interview Builder (3 sessions with mock interviews and individual feedback).
