Testing
Speech recognition has graduated from novelty to critical infrastructure. Voice assistants, call center automation, medical transcription, and accessibility tooling all depend on ASR systems that must perform reliably across accents, noise environments, and edge cases. Yet testing ASR is fundamentally different from testing a REST API or a UI component
Testing
Flaky tests put engineering teams in an impossible position. You can't ignore them—a flaky test might be covering a real bug. But if flaky tests block every CI build, developers start merging anyway, defeating the purpose of CI entirely. Quarantine is the middle path: isolate flaky tests
Testing
Play Framework has first-class support for Specs2. The framework provides helpers for testing controllers, routes, templates, and WebSocket connections without starting a real server. This guide covers the full Play + Specs2 testing stack. Setup Add to build.sbt: libraryDependencies ++= Seq( "org.scalatestplus.play" %% "scalatestplus-play"
Testing
Specs2 is a mature Scala testing library with two distinct styles — Acceptance (readable specification documents) and Unit (closer to xUnit). This guide focuses on the advanced features that make Specs2 stand out: custom matchers, data tables, ScalaCheck integration, and async testing. Two Styles, One Library Specs2 supports two test styles
Testing
You can't manage what you can't measure. This is as true for flaky tests as it is for application performance. Teams that "know they have flaky tests" but don't measure them will always have too many flaky tests—because there's
Testing
visionOS testing requires new mental models for input (eyes + hands, no touchscreen), space (3D window placement, volumes, immersive spaces), and audio (spatial positioning matters). Run unit and integration tests in the simulator for fast iteration. Device testing is mandatory for eye tracking accuracy, spatial audio presence, and real comfort validation.
IoT Testing
Over-the-air (OTA) firmware updates are one of the highest-risk operations in an IoT system's lifecycle. A bad update pushed to a fleet of 100,000 devices can brick them all simultaneously — devices that may be physically inaccessible in a factory, oil rig, or residential building.
Testing
Building a browser extension that works in both Chrome and Firefox sounds straightforward — both use the WebExtensions API. In practice, there are enough API differences, manifest differences, and behavioral quirks to make cross-browser extension testing its own discipline. This guide focuses on Firefox-specific testing: what's different
Testing
Financial applications carry a different kind of weight than a typical web app. A bug in a social media feed is annoying. A bug in a payment processor can cost your company millions, expose customer data, and trigger regulatory action. Fintech testing is not optional—it's the difference
Testing
Fintech applications face a distinctive compliance burden: multiple overlapping frameworks (PCI-DSS, SOC 2, GLBA, sometimes GDPR or CCPA) that each require evidence of specific technical controls. A compliance test suite — a structured collection of automated tests organized by compliance requirement — is the most sustainable way to generate that evidence
Testing
Biometric authentication is now a standard feature in mobile apps, access control systems, and financial applications. But unlike a password check — which is deterministic — fingerprint and face recognition systems are probabilistic. That fundamental difference makes testing them genuinely hard. A threshold that works for 99.9% of users will fail
SonarQube
SonarQube doesn't run your tests — it reads coverage reports that your test runner produces. To see coverage in SonarQube, you need two things: a test run that generates a coverage file (LCOV, JaCoCo XML, Cobertura XML, etc.) and a scanner configuration that tells SonarQube where to find it.
