Using PHPUnit in PhpStorm is trivial when PHP is installed locally. With Docker interpreters, Magento-specific bootstrap files and integration tests that require a running database, the configuration becomes more complex. This guide shows how to solve each of these cases cleanly.

Accessibility in a React Native app isn't a CSS afterthought like on the web, it requires deliberately set accessibilityLabel values, roles and a well thought out focus order from the very start. Ignoring these fundamentals effectively excludes screen reader users of VoiceOver and TalkBack from the app, and since the European Accessibility Act it also carries legal consequences.

A backup that has never actually been restored is an unproven assumption, not a reliable safety net. Automated restore tests regularly check whether a backup really works, whether the data is complete, and how long an actual restore takes. This article shows how to establish restore tests for Linux servers as a fixed, monitored part of operations.

A single conditional type checks a condition once. Recursive conditional types apply the same condition to themselves again and again until a base case is reached, turning nested objects, tuples, and strings into fully transformed types at compile time. Once you know the mechanics, the depth limit, and the tail recursion pattern, you can write DeepReadonly, tuple reverse, or recursive template literal types confidently on your own.

The slow query log is only the first step, because a raw file with thousands of lines does not deliver insight on its own. This article shows how to choose long_query_time sensibly, how pt-query-digest and mysqldumpslow aggregate the data, and how to turn that into a solid prioritization for the next round of optimizations.

Plain HTTPS trusts the entire operating system trust store, and that is exactly the gap rogue CAs, corporate proxies and tools like mitmproxy exploit. SSL pinning locks a certificate or public key directly into the app and turns intercepted traffic into a dead end for attackers, once certificate pinning and public key pinning are implemented cleanly for iOS and Android, tested properly and backed by a rollover strategy.

Not every compatibility module deserves a place in production. Anyone who enables Luma fallbacks blindly instead of auditing them deliberately pays with load time, CSP violations, and unnecessary maintenance effort for rendering paths that no customer ever sees.

A failed end-to-end test typically returns only an error message and a stack trace at the test framework level, revealing nothing about what actually happened in the backend during that particular test run. Test observability closes exactly this gap by correlating distributed tracing, structured logs, and metrics with the given test run, so a single glance at a red test immediately reveals whether the cause lies in the frontend, in a specific backend request, or in a third-party integration, instead of having to painstakingly reconstruct manually which service was involved at which point in time.

The order success page is the moment with the highest attention throughout the entire checkout: the customer has just made a purchase but is still on the page. Anyone who uses this moment for conversion tracking, cross-sell, and customer retention, without Knockout.js, jQuery, or UI components, but with clean Hyvä patterns built from ViewModels, layout XML, and Alpine.js, gets noticeably more out of the order success page than with the standard Luma output.

A missing, hidden, or outdated legal notice is one of the most common reasons for a formal warning letter in German online retail, and it affects small side-business shops just as much as established companies. This article explains in plain language which details a legal notice must contain, what changed with the new Digital Services Act, and how to reliably avoid common warning letter traps.
