Frontend and API Testing Using Cypress and Postman

March 25, 2022

During a recent Postman livestream with the senior director of engineering at Mercari, Dr. Gleb Bahmutov, PhD, we wrote frontend and API tests using Cypress and Postman, and then we ran them as part of a continuous integration pipeline in CircleCI.

Previously the VP of engineering at Cypress, Gleb is now one of the foremost instructors on Cypress technology and has strong opinions about the importance of testing in a modern software development team.

“If you’re a developer, and you don’t identify as a tester as well, you’re not a real developer.”
— Dr. Gleb Bahmutov, PhD, senior director of engineering at Mercari
