CLI TEARDOWN GETS 5X FASTER AS ISAAC ROLDÁN KILLS THE FLAKIEST E2E BOTTLENECK

Shopify's test suite just shed its worst leak: app cleanup now runs in parallel via Admin API instead of clicking through the UI, cutting E2E teardown from minutes to seconds.

Isaac Roldán shipped three interconnected wins across the CLI repo that transform E2E reliability. First, the teardown now uninstalls apps via the Admin API [1], ditching the Playwright clicks through Polaris modals and hard-coded waits that were causing leaked stores and apps. Then cleanup itself parallelizes with a five-worker pool [2], batching page aggregation across isolated Playwright instances. The real leverage, though, comes upstream: E2E tests no longer run at all if the build breaks or TypeScript drifts [3]. Roldán's 90-day failure audit found 308 false-positive E2E failures that weren't E2E problems at all, polluting signal and eating CI budget. "~12% of classified failures were not E2E problems at all," Roldán noted in the analysis [3]. All three changes merged and are live. Over in Hydrogen, Frederico fixed a monorepo command path bug where the nested `hydrogen:customer-account:push` discovery was shadowing the canonical `customer-account-push` command, forcing users back to the bundled Shopify CLI version [4].
