We’re currently working on a TypeScript Node.js backend project with Fastify as the framework, and we’re using TAP (Test Anything Protocol) for our testing needs. However, we’ve encountered performance issues with TAP, particularly with slower test execution times for our large test suites and numerous endpoints.

In light of this, we’re considering migrating to Jest as our testing framework, but we’re seeking advice and insights from the community before making a decision. We haven’t been able to find comprehensive reviews or comparisons between TAP and Jest, especially in the context of TypeScript, Node.js, and Fastify.

Any insights, experiences, or recommendations would be greatly appreciated. We’re looking to make an informed decision that balances performance, functionality, and ease of integration for our testing needs.

Thanks in advance for your help!

In our project, we’ve been using TAP (Test Anything Protocol) for testing our TypeScript Node.js backend built with Fastify. However, as our project has grown, we’ve encountered performance issues with TAP, especially when running large test suites and numerous endpoints.

To address these performance concerns, we’re considering migrating to Jest as our testing framework.
