End-to-End Testing That Your Team Actually Trusts

That's almost always one of a handful of specific, avoidable failure modes rather than bad luck. The most common are brittle selectors (targeting CSS classes that change with unrelated styling tweaks), manual hardcoded waits instead of auto-waiting, tests written against implementation details rather than user behavior, and missing test isolation — where a test depends on state left behind by a previous test, so it passes alone and fails in CI. Each of those trains a team to stop trusting failures, which is how a suite becomes something people ignore.

Playwright is our default for new work, and yes, we work with existing Cypress or Selenium suites. The reason for the Playwright default is specific rather than preferential: it communicates directly with the browser instead of going through WebDriver (Selenium) or running inside the browser (Cypress), which measurably reduces flaky tests and speeds up execution. If your existing suite is stable and your team knows it well, extending it is often the better call — we won't recommend a migration that isn't justified by a real reliability or speed problem.

It depends on how many critical flows you have and what state your existing coverage is in. Mapping the critical paths is fast; the build itself scales with flow count and complexity. If you already have a suite, the flake audit comes first — we fix the foundation before adding new tests on top of it, which is the opposite of the common approach of piling more tests onto an already-unreliable suite. We scope it as a focused first step so you can validate the approach before committing to full coverage.

Both. Functional assertions verify behavior — that a flow completes, a value is correct, an error state appears. Visual regression testing uses screenshot comparison (Playwright's toHaveScreenshot) to catch layout-level bugs that functional assertions miss entirely: a layout that's visibly broken can still pass every functional check. We use perceptual diffing rather than raw pixel comparison so anti-aliasing and dynamic text don't produce false failures, while real layout regressions still surface.

Through staged gates rather than running the full suite everywhere. Fast checks run on every commit and block it in minutes; the heavier E2E regression runs pre-production and blocks release rather than blocking every commit. Parallel execution — a genuine Playwright strength — keeps suite runtime low enough that running it on every pull request stays practical, which matters because a suite that's too slow to run gets skipped under deadline pressure, and a skipped suite provides no protection at all.
