From Requests to Reports: Clean Logging in API Testing

While many testers are familiar with the basics of API testing—validating status codes, parsing response bodies, and testing CRUD operations—expert-level API testing goes far beyond that. To build a resilient and maintainable test suite, testers must adopt advanced practices like structured logging, traceability, and clear reporting. In this article, we explore logging best practices that are largely tool-agnostic, but we'll demonstrate them using PactumJS, a powerful and extensible API testing tool, along with Mocha, a popular JavaScript test framework. For logging, we’ll use Pino, one of the fastest and most reliable structured loggers for Node.js. Here is the sample repo https://github.com/pactumjs/pactum-mocha-boilerplate to see the code in live action.
