Are there testers in the team?

The presence of testers in the team depends on the structure and processes of the project. In some teams, especially large ones or those with high quality requirements, dedicated QA engineers are involved in functional, load, and automated testing.

In other cases, testing responsibilities may be distributed among developers (for example, writing unit tests, integration tests) and product managers. PHP projects often use tools for automated testing, such as PHPUnit.

If there are no dedicated testers in the team, it is important that developers ensure code quality through test coverage and code reviews, as well as use CI/CD for automation of checks.
