Is there a promotional code for HN? I was a happy user of HTMLUnit [1] with Jython [2] in the past and am very interested in a future where we can automatically generate portions of browser code using code generation and verification techniques. I've never felt as comfortable with tools like Playwright/Cypress/Selenium as I did with HTMLUnit (with all due respect to both).
