Sorry but I can't provide more objective reasons why not use Cypress except that cypress is more about aggressive marketing and promotion, but not a useful tool for testing. I don't want to write node.js inside separate files, I want to use it without limitations, for manipulating with DOM and http. I want to use normal async/await, as all adequate people do nowadays while using ES. Even when I wanted to make multipart-form-data request I found that it's not possible using Cypress. But it's quite a trivial common thing, I didn't want something unique, or am I?
