Do you apply the testing pyramid in your project? How do you understand that it is indeed a pyramid?

Yes, I apply it. The testing pyramid is a concept where a large number of unit tests are at the bottom, fewer integration tests are in the middle, and even fewer UI/end-to-end tests are at the top. This ensures quick and reliable feedback, reduces the cost of maintaining tests, and accelerates development.

I understand this is a pyramid if:

• Most tests are fast and isolated unit tests.
• Integration tests cover interactions between components, but are fewer.
• UI tests are minimal, covering only critical scenarios.

Such a balance helps quickly find errors and maintain quality without excessive costs on slow and fragile tests.
