What kind of tests exists for the demo

Question

What are the kinds of tests existing in this demo for each of the services in the programming language and if it's possible to add tests whether unit or integration tests if necessary to this demo?

The demo has a set of Cypress end-to-end testing scripts as part of the frontend and a full set of trace-based tests.
The Cypress tests are in the src/frontend/cypress/e2e folder. You can find the trace-based tests in test/tracetesting.
To execute the tests, run make run-tests

What about for tests such as Rust language, Golang or other languages, are there need to write further

Hi @Killpit, I'm sorry for not returning to this message earlier. We don't need to run unit tests in the demo since it is quite simple already. Ideally, the tests run in the demo are end-to-end and focused on ensuring the telemetry generated is proper.

That said, the trace-based testing framework used by the demo needs to be revamped. #1814 discusses how our existing framework has been failing us lately.
