prescript is a Node.js-based test runner that helps make it fun to write end-to-end/acceptance tests.
Writing functional and end-to-end tests (e.g. using Puppeteer or Selenium) with unit-testing frameworks such as Mocha can sometimes be painful, because when one step failed, you have to re-run the test from the beginning to verify that you fixed it. End-to-end tests is usually very slow compared to unit tests.
prescript solves this problem by allowing you to express your tests as multiple, discrete steps. prescript then comes with an interactive development mode, in which you can hot-reload the test script and jump between steps.
This means as you run your tests as you write it. And if you make a mistake you can fix your test, hot reload, and continue testing, without having to re-run the whole test suite.
