Master API Contract Testing: The Ultimate Postman Guide

Join us for a one-hour, intermediate-level Postman training geared specifically for API testers and other stakeholders invested in the health of your APIs, including product managers, business managers, DevOps practitioners, and more. When it comes to API Contracts, having a goal of “meets expectations” is exactly what you want to strive for. This workshop will focus on various ways to check your OpenAPI Specification for validity, all the way down to data types of your responses. We'll also cover some testing methods to double check the schema in test scripts as well if you're not using OpenAPI. We'll look at advanced options for alerting when things don't match. Guests: - W.
