Flutter
Flutter tests that hit real HTTP endpoints are slow, flaky, and environment-dependent. The solution: inject a fake HTTP client, intercept requests at the Dio layer, or run a lightweight mock server. This guide covers all three approaches with working examples. Key Takeaways Inject http.Client as a dependency. Don&
Monitoring
Before users report a broken checkout or a slow login page, you want to know about it. Synthetic monitoring is the discipline of simulating user interactions from external locations on a continuous schedule — confirming that your application works correctly even when no real users are actively using it. Splunk Synthetic
Flutter
Flutter golden tests capture pixel-perfect screenshots of your widgets and fail when the output changes. They are the fastest way to catch visual regressions — a changed color, a broken layout, a clipped text — without manual visual review. This guide covers the full workflow: writing goldens, updating them intentionally, handling
Monitoring
Your application logs everything. Every HTTP request, every database call, every exception, every slow query. This data stream is one of the most valuable sources of truth you have — but raw log files are unreadable at scale. Splunk was built to solve exactly this problem, and for QA and engineering
Flutter
Patrol is a Flutter testing framework built on top of integration_test that lets you interact with native UI elements — permission dialogs, notifications, the status bar, deep links — without platform-specific ADB/xcrun hacks. This guide covers setup, writing PatrolTester tests, handling permissions, testing notifications, and running Patrol in CI.
Flutter
Flutter has two end-to-end testing frameworks: the legacy flutter_driver and the modern integration_test package. For new projects, use integration_test — it runs in the same process as your app, works with flutter test, and supports Web and Desktop. flutter_driver remains useful for specific scenarios like
.NET
Unit tests fail for two reasons: the code is wrong, or the assertion message is so cryptic you spend 20 minutes figuring out what it even checked. FluentAssertions solves the second problem completely. FluentAssertions is a .NET library that replaces Assert.AreEqual(expected, actual) with a fluent, English-like API.
Monitoring
Distributed systems fail in distributed ways. A request that touches 12 microservices before completing can fail or slow down at any of 12 points — and without distributed tracing, finding which one is a process of elimination that can take hours. Splunk APM is built to eliminate that investigation time, providing
Testing
Fluent assertions are only as good as the discipline you apply when writing them. A test with three chained assertions that all test the same thing is worse than one clear assertion. Here's how to write assertions that are actually useful. Assert Behavior, Not Implementation The most common
Testing
Race conditions are one of the hardest bugs to find with tests. A threading bug might only trigger after a specific interleaving of 8 operations across 3 goroutines, and the window for that interleaving might be 10 nanoseconds. You could run the test a million times and never hit it
Testing
Flaky tests are the silent killers of CI/CD confidence. A test that passes sometimes and fails other times isn't just annoying—it erodes trust in your entire test suite. When developers start ignoring red builds because "it's probably just a flaky test," you&
Testing
Retrying failed tests is the fastest way to make flaky tests disappear from your CI dashboard. It's also the fastest way to miss a real bug. Understanding the difference between these two outcomes determines whether your retry strategy helps or hurts. The Seductive Simplicity of Retries Adding retries
