Selecting cypress:

So let's hope we don't need multiple tabs / browsers any time soon.

But like the versatility of the assertions:
https://docs.cypress.io/guides/core-concepts/writing-and-organizing-tests#Dynamically-Generate-Tests
- so that tests read better

Also aliases,
better structure to get access to work product of async cypress commands.

Good general bunch of best practices listed out:

Codeless platforms also look interesting. But I am pretty sure that we will run out of room soon for the things we need to test.

For BDD
several choices:

chai

jasmine
https://jasmine.github.io/index.html

mocha
https://mochajs.org/

cucumber
serenity

For browser interaction:

https://www.selenium.dev/documentation/webdriver/

https://playwright.dev/
- new kid on the block

puppeteer

Selenium + javascript
- this was too tempting

karma-js
https://karma-runner.github.io/latest/index.html

serenity 
https://serenity-js.org/handbook/why-serenityjs.html
https://serenity-js.org/handbook/integration/architecture.html

what I really wanted was - serenity + cypress
https://github.com/serenity-js/serenity-js/issues/846

may be the path to above integration is:
