We’ve all been there: you run your tests, everything looks fine, then you push to CI and suddenly a few tests fail for no clear reason. You rerun the pipeline, and like magic, they pass again. Those are flaky tests, and they consume time, slow down releases, and erode team confidence in their test suite.

In this talk, I’ll break down the common causes of flaky tests — from timing issues and async quirks to unstable networks and hidden dependencies. I’ll also share real examples of how to fix them using Jest, Cypress, and Playwright.

By the end, you’ll have practical strategies you can apply right away to make your tests more reliable, so your team can move faster with fewer frustrations.
