Crate trillium_testing

testing utilities for trillium applications.

this crate is intended to be used as a development dependency.

use trillium_testing::prelude::*;
use trillium::{Conn, conn_try};
async fn handler(mut conn: Conn) -> Conn {
    let request_body = conn_try!(conn.request_body_string().await, conn);
    conn.with_body(format!("request body was: {}", request_body))
        .with_status(418)
        .with_header("request-id", "special-request")
}

assert_response!(
    post("/").with_request_body("hello trillium!").on(&handler),
    Status::ImATeapot,
    "request body was: hello trillium!",
    "request-id" => "special-request",
    "content-length" => "33"
);

Features

You must enable a runtime feature for trillium testing

Tokio:

[dev-dependencies]
# ...
trillium-testing = { version = "0.2", features = ["tokio"] }

Async-std:

[dev-dependencies]
# ...
trillium-testing = { version = "0.2", features = ["async-std"] }

Smol:

[dev-dependencies]
# ...
trillium-testing = { version = "0.2", features = ["smol"] }

Re-exports

• pub use futures_lite;

Modules

• methods
  TestConn builders for http methods
• prelude
  useful stuff for testing trillium apps

Macros

• assert_body
  assert that the response body is as specified. this assertion requires mutation of the conn.
• assert_body_contains
  asserts that the response body matches the specified pattern, using str::contains
• assert_headers
  asserts any number of response headers
• assert_not_handled
  assert that all of the following are true:
• assert_ok
  assert_ok is like assert_response! except it always asserts a status of 200 Ok.
• assert_response
  combines several other assertions. this assertion can be used to assert:
• assert_status
  assert that the status code of a conn is as specified.

Structs

• ClientConfig
  configuration for the tcp Connector
• RuntimelessClientConfig
  An in-memory Connector to use with GenericServer.
• RuntimelessServer
  A [Server] for testing that does not depend on any runtime
• ServerConnector
  a bridge between trillium servers and clients
• SpawnHandle
  A droppable future
• TestConn
  A wrapper around a trillium::Conn for testing
• TestTransport
  a readable and writable transport for testing
• Url
  A parsed URL record.

Enums

• Method
  HTTP request methods.
• Status
  HTTP response status codes.

Traits

• AsyncRead
  Read bytes asynchronously.
• AsyncReadExt
  Extension trait for AsyncRead.
• AsyncWrite
  Write bytes asynchronously.

Functions

• block_on
  Runs the global and the local executor on the current thread
• client_config
  runtime client config
• config
  runtime server config
• connector
  build a connector from this handler
• harness
  a test harness for use with [test_harness]
• init
  initialize a handler
• spawn
  smol-based spawn variant that finishes whether or not the returned future is dropped
• with_server
  Starts a trillium handler bound to a random available port on localhost, run the async tests provided as the second argument, and then shut down the server. useful for full integration tests that actually exercise the tcp layer.
• with_transport
  open an in-memory connection to this handler and call an async function with an open BoxedTransport

Type Aliases

• TestResult
  a sponge Result
