Why Move from Manual to Automation Testing?
1: What is software testing?
Manual testers spend hours running repetitive test cases. Automation testers write scripts to do it in minutes. Speed is a major reason to switch. Automated tests scale for large projects, running thousands of checks across devices and browsers. They’re reliable, reducing human error. A single typo in manual testing can miss a critical bug—automation avoids that.
Industry demand is another driver.
Faster release via automation is the focus for companies like Google, Amazon, and startups. Jobs boards indicate that automation testers are making between $80000 $120000 a year, and manual testers between $60000 and $90000. This is becoming a gap as more companies use CI/CD pipelines.
Opportunities for career advancement are one of the many benefits. Automation testers are working with the most innovative tools that provide better coverage, with some frameworks achieving coverage of 90% as opposed to 60% when using manual testing. You will work on different projects, web apps, and APIs, and be respected in an agile team. Being a manual tester can lead to stagnation. Automation leads to advancement into positions such as test architect or DevOps engineer.
