Testing
Testing asynchronous, event-driven systems is genuinely hard. The problems stack up fast: you can't assert response.status_code == 200 when the operation happens asynchronously; your test needs to know when to stop waiting; race conditions create flaky tests that pass locally and fail in CI; and the message
Testing
When a microservices integration test fails with a vague 500 error, you have a problem: the error came from somewhere in a chain of four services, passed through an API gateway, and touched a database and a message queue. The stack trace in your test output tells you where the
IaC Testing
Compliance frameworks like CIS Benchmarks contain hundreds of controls. Auditing them manually—or trusting that your IaC applied them correctly—is a recipe for drift. InSpec turns benchmark requirements into executable tests that run after provisioning and on a schedule. Here's how to go beyond the sample profiles
Accessibility Testing
Deque Attest (formerly WorldSpace Attest) is Deque's enterprise accessibility platform. It sits above axe DevTools and axe-core in Deque's product stack, targeting organizations that need coordinated testing across dozens of apps, centralized reporting, and issue tracking integrated into existing workflows. This post covers where Attest fits,
Testing
Integration testing microservices is notoriously painful. You need real instances of every dependent service, a shared environment where everyone's changes play nicely together, and the patience to debug failures caused by a schema change three teams made two weeks ago. Contract testing — specifically consumer-driven contract testing — cuts through
Testing
Behavior-Driven Development is one of the testing practices that attracts the most skepticism from engineering managers and product leaders. The criticism is consistent: BDD is slow to set up, it requires collaboration across teams, and the benefits are diffuse and hard to quantify. Meanwhile, the costs are immediate and visible
Testing
Cucumber is one of the most widely used BDD frameworks, and it has one of the highest rates of teams abandoning it after six months. The reason is almost never the tool itself — it's the practices teams adopt when they first set it up. Cucumber gets blamed for
Testing
Enterprise software quality assurance is a different discipline from testing a consumer SaaS. The stakes are different, the features are different, and the consequences of failure are different. When a consumer app has a bug, a user might churn. When enterprise software fails, it can disrupt the operations of an
IaC Testing
The basics of Atlantis—comment atlantis plan on a PR, review the plan, apply—are well documented. What's less covered is how to enforce policy at plan time, build reusable workflow components, and test your Atlantis configuration before it breaks a production PR. This post goes deep on
Testing
Getting BDD tests to pass on a developer's laptop is one problem. Getting them to run reliably in a CI/CD pipeline — in parallel, with good reporting, fast feedback, and minimal flakiness — is a different problem entirely. Many teams set up Cucumber locally but struggle to make it
Testing
Netflix streams to over 230 million subscribers worldwide. When a server fails at 9 PM on a Friday, the engineers on call cannot afford to learn for the first time that their service cannot handle the outage. Chaos Monkey was born from this exact problem: a tool that randomly terminates
Testing
APIs are the backbone of modern applications. They are also the primary attack surface. While web application security testing has decades of tooling and methodology behind it, API security testing is often treated as an afterthought — a Postman collection with some happy path tests and nothing more.
