How can the number of testers in the team be determined?

The determination of the number of test team members depends on several factors:

• Scope and complexity of the project. The more functionality and the more complex the product, the more testers may be needed.
• Deadlines and timeframes. If there is a need to quickly cover a large volume with tests, the team should be larger.
• Types of testing. Whether automation specialists, load testing, functional testing, etc., are needed.
• Budget and resources. Financial constraints and the availability of specialists.

An approximate approach is to estimate the volume of test scenarios, the time to execute them, multiply by the number of testing cycles, and then divide by the available working time of one tester. This will give an approximate number of specialists.

It is also important to consider the possibility of automation, which can reduce the need for manual testing.
