This means we will have to implement this ourselves. Perform HTTP Authentication with browser.newContext(). This helper allows to mock requests while running tests in Puppeteer or WebDriver . In one of my previous articles about decoupling E2E tests I was reasoning about why we should switch from full-blown E2E tests to much more isolated UI tests.
