Accessibility Testing
A SaaS application has specific accessibility challenges that generic checklists don't address: authenticated dashboards, complex data tables, modals triggered by user actions, real-time updates, and multi-step workflows. This checklist is organized by what to check at different stages of development and before release. Why SaaS Products
Test Automation
Writing unit tests is one of the most time-consuming parts of Java development — and one of the most frequently skipped. Diffblue Cover addresses this by generating JUnit tests automatically using AI. This guide walks through installation, first run, and what to do with the tests it produces. What Diffblue
Testing
Rust is the dominant language for production WebAssembly. The Rust/Wasm toolchain — wasm-pack, wasm-bindgen, and web-sys — is mature and well-documented. But testing Rust Wasm projects requires thinking at multiple levels simultaneously: Rust logic, Wasm compilation, JavaScript integration, and browser behavior. This guide covers the complete testing
Test Automation
Running Diffblue Cover locally is useful for one-off coverage boosts. The real leverage comes from integrating it into CI — automatically generating tests when coverage drops, or regenerating tests when code changes. This guide covers the practical setup for Jenkins, GitHub Actions, and GitLab CI. Prerequisites CI integration requires the
Testing
Rust compiled to WebAssembly introduces a new class of testing challenge: your code runs in a browser or Node.js context, not on the OS. Standard cargo test doesn't run wasm tests. wasm-pack test does. This guide covers how to write testable Rust wasm code, use wasm-
Testing
Devin AI is the most autonomous coding assistant on the market. It doesn't just suggest code — it executes tasks autonomously. Give it a GitHub issue, it reads the codebase, writes a fix, runs tests, and submits a pull request. The PR comes with test results attached. For QA
Testing
Test-driven development (TDD) is shift-left taken to its logical extreme: tests are written before the code they test. This forces quality considerations to happen at specification time — the earliest possible moment. This guide covers the TDD cycle, why it's the most effective shift-left practice available,
Testing
Testing async Rust code with #[tokio::test] handles the basics — but complex async patterns (state machines, channels, time-dependent logic, concurrent operations) need more. This guide covers advanced async testing patterns beyond the basics. The Foundation: #[tokio::test] The baseline for async Rust tests: [dev-dependencies] tokio = { version = "1&
Testing
"Shift-left" is a term that's been used in software engineering long enough to become jargon. The original meaning is simple: move testing earlier in the development process, closer to when code is written, rather than leaving it to a dedicated QA team at the end
Testing
The inner loop is the cycle a developer goes through hundreds of times a day: write code, run tests, check the result, fix what's broken, repeat. If that loop is slow, broken, or painful, developer productivity suffers. If it's fast and reliable, developers can move quickly
Testing
Rust has three places to write tests: inline in the source file, in a tests/ directory for integration tests, and in doctests. Most guides cover these in isolation. This guide covers how to organize them as your project grows — shared utilities, feature-gated tests, test fixtures, and keeping test code
Rust
Code coverage tells you which lines your tests exercise. It won't tell you if your tests are good, but it does tell you what you're definitely not testing. In Rust, you have two main options: cargo-tarpaulin and cargo-llvm-cov. This guide covers both, when
