  Node.js library to automate Chromium, Firefox and WebKit with a single API

  Latest mention: Developing for Safari on Windows 10 / Linux | dev.to | 2021-01-23

  Ok, enough of tension building – let us jump to the solution 😀 So ... have you heard of Playwright? If your answer is no, then let me tell you that Playwright is a Node.js library to automate Chromium, Firefox and WebKit with a single API. In fact, the API is very simular to Puppeteer, because two of the Developers moved from Puppeteer to Playwright. (cf. Puppeteer Contributions vs. Playwright Contributions) If your answer is yes, and if you are not using Safari yet for testing purposes as Windows or Linux user, then congratulations, you are just like me 🤡.

  Latest mention: Prefer Fakes Over Mocks | dev.to | 2020-10-13

  According to the original definitions introduced by Gerard Meszaros, a mock is a very specific type of substitutes which is used to verify interactions between the system under test and its dependencies. Nowadays, however, the distinction has become a bit blurry, as this term is commonly used to refer to a broader class of objects created with frameworks such as Moq, Mockito, Jest, and others.
