A library for writing spin-test tests in Rust.
The spin-test Rust SDK allows you to annotate functions as spin-test tests that will automatically be exposed to spin-test as tests to be run:
use spin_test_sdk::{bindings::wasi::http, spin_test};
#[spin_test]
fn my_test() {
// Make a request to the Spin application
let request = http::types::OutgoingRequest::new(http::types::Headers::new());
request.set_path_with_query(Some("/?user_id=123")).unwrap();
let response = spin_test_sdk::perform_request(request);
// Assert response status
assert_eq!(response.status(), 200);
}The spin-test Rust SDK gives access to the fermyon:spin/test world through the bindings module. You can use the various types in that module to customize your test scenario, make requests against the Spin application, and make assertions about the state of the world before and after the request has been made.
As an example, in the following code, we are seeding the key-value store our Spin app has access to with some values to test that our app can handle when the key-value store is in such a state:
// Open the store
let key_value = key_value::Store::open("default");
// Set state of the key-value store
key_value.set("123", "abc");
// Now make our request to the Spin app...
