API testing and API monitoring are vital parts of a successful API program, just like API design and API documentation. However, what is the difference between testing and monitoring, considering some overlap in approach and tooling? My take on this is that testing is primarily a part of building APIs, whereas monitoring is mainly about running APIs in production. I published the extended version of my comparison as a new article on the BlazeMeter blog, called “API Testing and API Monitoring: The Complete Guide”. I’m happy to continue my previous partnership with their company to explore and write about API life cycle topics. You can find additional articles I wrote for them and other clients on my Writing page, and I’m open to new writing contracts as well.
