ConfIT

ConfIT is a library for defining integration and component-style API tests declaratively in JSON rather than writing test flows imperatively in code. We're seeing increased interest in this approach, as large test suites often accumulate boilerplate around HTTP clients, request setup and assertions. AI-assisted development further reinforces this trend, making structured test definitions easier to generate and maintain than verbose procedural code.

Based on client experience and our evaluation, a declarative layer can reduce duplication between component and integration tests, improve readability and make test intent easier to evolve across teams. However, ConfIT itself appears to have limited community adoption and a small ecosystem, making it harder to recommend broadly despite these benefits. We think ConfIT is worth assessing for .NET teams exploring specification-driven API testing. Teams should, however, validate its long-term maintainability, ecosystem fit and operational trade-offs before adopting it more widely.
