Case Study: Eventbrite achieves faster cross-browser WebGL testing and recovers developer time with Rainforest QA

How Eventbrite Uses Rainforest for Cross-Browser Testing

Eventbrite’s Reserved squad faced a tricky cross-browser testing problem: their seat reservation flow relies on WebGL-rendered venue maps that expose no DOM elements, making Selenium scripts brittle, slow, and costly to maintain across many browsers and versions. Amber Rockwood described how the team needed reliable acceptance tests for these complex, multi-page flows without spending hundreds of engineering hours on fragile WebDriver tests.

They adopted Rainforest’s human-executed testing on VMs to avoid scripting exact coordinates and to flexibly add or remove browser coverage without rewriting tests. The change recovered developer time, sped up test execution by loading precise test states, and helped catch browser-specific and multi-page bugs before release—while the team continues improving Rainforest’s visibility in their CI pipeline.
