malabi VS opentelemetry-ext-js

Back in 2018, Trace-based testing was just an idea. Fast-forward to today: TBT is now a reality, thanks to Trace standardization à la OpenTelemetry (OTel) and Trace-based testing tools like Tracetest, Helios, and Malabi.

Malabi is an open-source test framework. With Malabi, you can write integration tests on distributed systems by collecting data from a microservice during a test run, then exposing an endpoint to make assertions on that data. The maintainers say Malabi implements trace-based testing, similar to Tracetest. Malabi uses OpenTelemetry to collect your trace data.

This use case is exactly what has led to the creation of Malabi, an open-source that wraps the OpenTelemetry SDK and does all this setup for you so that you can simply add it to your project and start asserting.

Malabi is still in its early days, so if you find it interesting, feel free to help in any way (contribute code, knowledge, or ideas). https://github.com/aspecto-io/malabi ⭐️

AWS has good tools for tracing, but in this example, I will use another remote and distributed tracing platform – Aspecto.

For this article, I will be using Aspecto to visualize my traces. You can follow along by quickly creating a free account.

If we drill down into one of these traces, we can see in more detail how long each request took and clear visualization of the entire workflow.

For the purposes of this guide, I chose to use Aspecto as my visualization tool. This is because Aspecto provides built-in support for visualizing messaging systems like Kafka (and, of course, any other part of our microservice architectures).

To follow along, you can open a new free-forever Aspecto account or log in to your existing one.

That’s about it for this OpenTelemetry Java guide, folks. If you have any questions or issues with any of these steps, feel free to reach out to us via chat or join our OpenTelemetry Slack channel (part of the CNCF Slack).

At Aspecto, you can sign up for free and use our generous free-forever plan (no limited features).

Aspecto has a free-forever tier and provides everything included in Jaeger and more. Sort of like Jaeger on steroids.

However, you can take your tracing visualization to the next level with Aspecto. Try it yourself with the free-forever plan that has no limited features.

Hi all, we wanted to share some love back to the Kafka community. We hope you'd find this instrumentation helpful, check it out on GitHub 🌟and npm
