Manual testers

Manual testers are individuals who perform testing activities manually without the use of any automation tool or script. They follow a step-by-step approach to test an application’s functionality, usability, and other aspects to identify any defects. Manual testers can also perform exploratory testing, which involves a more free-form approach to testing an application, looking for unexpected bugs or issues.

Automation testers/SDET(Software Developer Engineer in Test)

Automation testers use various automation tools and scripts to perform testing activities. They write test scripts that can be executed repeatedly to check an application’s functionality, performance, security, and other aspects. Automated testers often use a combination of different tools, such as Selenium, Appium, and JMeter, to create automated test cases.

Performance testers

Performance testers are responsible for identifying the performance bottlenecks in an application. They test an application’s response time, scalability, and resource utilization to determine its performance under different workloads. Performance testers use tools such as LoadRunner, JMeter, and Gatling to simulate different user loads and measure an application’s response time and resource utilization.
