Automation testing vs. manual testing
It has been established that performing repetitive manual testing on large software systems or those with comprehensive dataset coverage is challenging. 2
Below, you can see statistics supporting organizations’ goals of moving from manual testing to automation testing.
- Manual testing is the most time-consuming activity in the testing cycle ( see Figure 1).
- Test Automation has replaced 50% or more of the manual testing efforts in 46% of the cases(See Figure 2). 3

Test development models/frameworks
Based on a survey 10 :
- Test-driven development as a development framework was used 18% of the time.
- In DevOps as a development model was used 38% of the time.
- API testing is an essential skill that the tester should be familiar with. 97% of responders indicated that API testing is crucial for their operational success.
- 99% of responders indicated that functional test automation and test scripting are crucial for them.
Market size & growth
According to KPMG 11 ;
- The global test market exceeded $40 billion in 2020.
- The global test market is expected to grow between 7% to 12% CAGR between 2021 and 2025.
