Increase API quality beyond functional testing

Making sure your APIs are accurate with functional testing is fantastic! Still, quality is about more than making sure the code works as expected; its also critical to know:

  • How much traffic can the API handle?
  • Is the API free from obvious security vulnerabilities?
  • Will I be able to deliver subsequent changes to the API on time and under budget?

SmartBear answers each of these questions through applications in the ReadyAPI suite, based on a decade of open-source testing experience.
