Show HN: Open-source cypress for back end testing

22 points

3 years ago

For the past few months we’ve been building a simple jest/typescript-based high-level language for writing and running integration tests. We're open-sourcing it now and are excited to share it with you: https://github.com/traceloop/jest-opentelemetry

Why we built this:

- There are many solid frameworks for FE / browser testing, but none with high-level constructs for testing BE flows

- We were missing a way to validate side effects for complex backend systems, especially across async queueing systems

Our beta version lets you send an API call to a system and then:

- Validate (=assert) calls to any downstream microservice in REST and GRPC

- Validate queries/writes to DBs

Assertions are validated through the use of OpenTelemetry, as we see it as an easy-to-use way to observe how backend systems behave.

We’re still early so would love your feedback and opinions.

It's all open-source with Apache 2.0 license.
