What problem does mockyeah solve?

mockyeah helps decouple HTTP integrations throughout development and testing.

Testing is difficult when you don't have control of your data. Developing service integrations can be a painful process. APIs designs are often influx, incomplete, unstable, or completely unavailable. mockyeah puts you in complete control, enabling you to implement mock HTTP responses with ease to integrate and test with during development. Real mock services means you have control of response payloads, HTTP status codes, response latency, and more.

Does your app have special behavior when a service is slow to respond or a server returns an unexpected status code? No problem! mockyeah makes developing for such requirements easy.

What is mockyeah's purpose?

  • To eliminate service side effects, increasing test durability
  • To provide dependable integrations
  • To isolate application behavior
  • To increase developer productivity
  • To increase integration testing performance by eliminating network latency
