In the complex landscape of UI testing, developers face numerous challenges in verifying component reliability and performance. This talk introduces a powerful approach using Storybook and Playwright that achieves total component isolation, moving beyond the limitations of traditional testing methods like E2E testing, mock browser environments, and hybrid solutions. This method provides unprecedented testing precision by rendering components completely outside their original application context. Participants will learn how Storybook and Playwright combine to create controlled, reproducible testing scenarios that address key weaknesses in existing strategies.

Initially, I will separate components testing from e2e testing and explain the advantages/disadvantages in each. Then I will cover 5 different approaches people use in testing their UI:

Storybook testing
Browser automation UI testing (Playwright / Cypress component testing)
Storybook + playwright UI testing
For each approach, I will explain what is required to make it work and the benefits and pitfalls for each one.
