Is it necessary to have a high level of programming skills to write effective tests?

For effective testing, you do not need to have a high level of programming skills, especially at the initial stages. The main thing is to understand the logic of testing, be able to formulate requirements and scenarios, and know the basics of testing languages and tools. However, as projects become more complex and testing automation grows, programming skills become more important, as they allow creating more flexible, maintainable, and efficient tests.

For example, to write simple unit tests in C#, basic knowledge of syntax and code structure is enough, while for complex integration tests or framework creation, deeper programming knowledge is required.
