Here is a situation most backend teams have lived through. A developer changes how the user service formats dates. It is a tiny change: one line, a cleaner ISO format, every unit test still green. The pull request gets approved in five minutes. Two days later, the billing service starts failing to […]

Ask five engineers whether a test is "functional" or "integration" and you will probably get three answers. That is not because people are confused. It is because the same test can honestly be both. Here is the short version. Integration testing checks that components work together. Functional testing checks that the software […]

Your frontend is ready, but the backend endpoint it depends on ships next sprint. Your QA team wants to test a payment flow, but the third party sandbox is down again. Your CI pipeline fails twice a week because a staging database returned different data. All three problems have the same fix: […]

For years, picking a BDD testing tool was a two-option decision: Cucumber if you wrote Java, JavaScript, or Ruby, and SpecFlow if you lived in .NET. That changed when SpecFlow reached end of life in December 2024, and newer stacks like Playwright and Go now have their own BDD options. This guide […]

Bruno is an open source, offline-first API client that stores your API collections as plain text files inside your Git repo. It gives you a fast GUI for building and sending REST, GraphQL, gRPC, and WebSocket requests, plus a scripting layer for writing tests against the responses. This guide covers Bruno API […]

Every tester has lost an afternoon to an environment that would not behave. The code was fine. The suite was fine. The problem was the ground the tests ran on. That ground has a name, and getting it right is quietly one of the highest leverage things a QA team can do. […]

The bug life cycle (defect life cycle) is the sequence of states a defect moves through from discovery to closure. Typical stages are New, Assigned, Open, Fixed, Retest, and Closed, with additional paths for Reopened, Deferred, or Rejected bugs. It gives teams a shared, trackable workflow for managing defects to resolution. Every […]

Software testing has four levels, also called the stages of software testing, and each answers a different question. Unit testing asks whether a single function works in isolation. Integration testing asks whether connected components communicate correctly – the layer where Keploy automates test generation from real API traffic. System testing validates the […]

Last updated: October 2026 API testing tools let teams send requests, validate responses, mock dependencies, and run tests inside CI/CD without writing every check by hand. For API test automation, the main options are Keploy, which generates tests and mocks from real API traffic or from an OpenAPI spec, Postman collection, or […]

I’ve seen teams burn weeks untangling API messes that could have been avoided with a couple of days of upfront thinking. Endpoints named inconsistently, versioning added as an afterthought, error responses that just say "something failed" all of it traceable back to the same root cause. Nobody sat down and actually designed […]
