wiremock grpc

Example

Generate Server Code

For each gRPC server you need to generate codes using the [generate!] macro.

rust mod wiremock_gen { // hello.Greeter: is the prefix of all rpc, // MyMockServer: name of the generated Server, wiremock_grpc::generate!("hello.Greeter", MyMockServer); } use wiremock_gen::*; // this imports generated use wiremock_grpc::*; // this imports MockBuilder

Use it

```rust

[tokio::test]

async fn default() { // Server (MyMockServer is generated above) let mut server = MyMockServer::start_default().await;

let request1 = server.setup(
    MockBuilder::when()
        //    👇 RPC prefix
        .path("/hello.Greeter/SayHello")
        .then()
        .return_status(Code::Ok)
        .return_body(|| HelloReply {
            message: "Hello Mustakim".into(),
        }),
); // request1 can be used later to inspect the request

// Client
// Client code is generated using tonic_build
let channel =
    tonic::transport::Channel::from_shared(format!("http://[::1]:{}", server.address().port()))
        .unwrap()
        .connect()
        .await
        .unwrap();
let mut client = GreeterClient::new(channel);

// Act
let response = client
    .say_hello(HelloRequest {
        name: "Mustakim".into(),
    })
    .await
    .unwrap();

assert_eq!("Hello Mustakim", response.into_inner().message);

// Inspect the request
// multiple requests
let requests = server.find(&request1);
assert!(requests.is_some(), "Request must be logged");
assert_eq!(1, requests.unwrap().len(), "Only 1 request must be logged");

// single request
let request = server.find_one(&request1);
assert_eq!(
    format!(
        "http://[::1]:{}/hello.Greeter/SayHello",
        server.address().port()
    ),
    request.uri
);

} ```
