What is Software Testing?
Software testing is systematically checking that applications work correctly, securely and meet requirements before users see them.
It spans manual test cases, automated scripts, API checks and performance testing.
Why employers value it
Shipping bugs is expensive. QA engineers and SDETs are hired to catch defects early and protect release quality as teams ship faster.
How to learn it
Learn manual testing discipline first—clear bug reports and test plans—then add automation with JavaScript or Python and a framework like Cypress or Playwright.
- Write test cases from requirements
- Report bugs with clear reproduction steps
- Automate key flows with Cypress or Playwright
- Test APIs with Postman or similar tools
Careers that use it
Software testing is core for QA engineers, SDETs and quality-minded developers.
Market outlook
Strong demand as continuous delivery grows; automation skills command higher pay.

Frequently Asked Questions
Is QA a good way to break into tech?
Yes. It is accessible, teaches how real teams ship software, and leads naturally into automation or development.
Manual vs automated testing?
Both matter. Manual finds exploratory issues; automation protects regressions on every release.
Do QA engineers need to code?
Manual QA needs little; SDET and automation roles require solid scripting skills.
