Writing integration tests for poem-openapi.

[mmittnacht]

Hello!

I would like to ask for assistance about writing integration tests in poem-openapi.

So far I have some handlers like:

struct TestHandler;

#[OpenApi(tag = "TestTag::Test"]
impl TestHandler {
    #[oai(path = "/test", method = "get")]
    async fn test_endpoint(&self) -> PlainText<String> {
           PlainText("Ok")
    }
}

creating function in tests/test.rs

#[cfg(test)]
mod tests {
    #[test]
	fn test_function() {
		let app = Route::new().at("/", TestHandler); // This is imported, but throws error:
													 // trait bound for TestHandler: poem:Endpoint is not implemented.
		let cli = TestClient::new(app);
		let resp = cli.get("/").send().await;
		resp.assert_text("test").await;
	}
}

Code like this throws the trait impl error in the comment section.

Also using the example from poem-openapi/tests it would work, though I need to pass PG conn with openapiservice.data, which will make the TestClient not accept the AddDataEndpoint<Box<dyn Endpoint<Output = poem::Response>>, Pool> type.

Is the a way to use an openapiservice with data appended?
