How to do integration testing in axum ?

Integration Testing

How can we perform integration test on our axum app?

...
|── src
│   ├── lib.rs
│   ├── main.rs
|── tests
│   ├── integration_test_one.rs
│   ├── health_check.rs
...

How can we do this?

Note: If my question can be improved, please suggest me as well.

Using "integration tests" (i.e. tests stored in the tests directory rather than src) is tricky because it requires you expose things (via pub) from your crate. In most cases if you're building a binary that isn't necessary. This is mainly intended for libaries.

I recommend you write tests in directly in src like its done in this example https://github.com/tokio-rs/axum/blob/main/examples/testing/src/main.rs

Hello @davidpdrsn
I'm curious to know how to do it. Isn't it possible to write tests in test directory?

Thanks

I feel like I answered that question already. Yes its possible, but intended for library developers.

Do this https://github.com/tokio-rs/axum/blob/main/examples/testing/src/main.rs instead.
