A two-test Playwright run against Sauce Demo, the JUnit XML it produced, and what PublishTestResults@2 does with that file on its documented defaults — including the pattern that matches nothing and the switch that lets failing tests pass. Then the other half: why publishing results never creates a Test Case, and the CSV format that does.

A catalogue of API test cases where every case was sent to a real API. 34 requests to Restful Booker, grouped by endpoint, with what a well-behaved API should return and what this one did, followed by a Playwright spec that checks the contract and records the known defects.

Should you use page objects, fixtures, or plain hooks in Playwright? We wrote the same three Sauce Demo tests all three ways, ran them, and measured the differences: how much code each needs, how many places a locator lives, where a failure points when a locator breaks, and what a beforeEach does to a test that doesn't need it.

A login page test case list where every case was run. 22 cases against Sauce Demo, grouped by what they protect, with the error text the site actually showed, the cases a practice site can't answer, and a data-driven Playwright spec with its real output.

A hands-on introduction to accessibility testing. Scan a page with axe, read a violation properly, see the same bug in the accessibility tree and in your locators, then find out why a keyboard pass misses it entirely. Includes an exercise with an answer key.

A pairwise model of the Sauce Demo checkout, 31 generated cases run as a data-driven Playwright test on Chromium, Firefox, and WebKit, and a run of every account, product, and form combination to check what those cases found and what they could have missed.

A measured look at Playwright's toHaveScreenshot: how many pixels a real regression changes, why maxDiffPixels: 100 and maxDiffPixelRatio: 0.01 can hide it, what animations: 'disabled' does not freeze, and how to handle baselines in CI.

What a retried flaky test actually looks like in Playwright's list, JUnit, and JSON reporters, how we diagnosed a real one on this site, and a quarantine policy with owners and expiry dates that CI enforces.

One test (log in, add a product, check the cart badge) written in Cypress, Playwright, and Selenium against the same public demo shop. How the code differs, how long each run took, what broke during setup, and which framework fits which team.

Create a Playwright project, write login and checkout tests for a real demo shop, see what a failing assertion looks like, and use fixtures and the trace viewer. Copy the code and it runs.

A fixed wait that added up to five seconds to a test, an assertion that passed for text that doesn't exist, a click on the wrong product, and a dialog listener that froze the page. Each mistake is reproduced with real output, and each has a fix.
