Wait for text to appear when using Puppeteer

You can use waitForFunction. See https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagewaitforfunctionpagefunction-options-args

Including @elena's solution for completeness of the answer:

await page.waitForFunction('document.querySelector(".count").inner‌​Text.length == 7');
