Record-and-replay testing middleware for reqwest http client.
Inspired by:
Builds on top of:
To record HTTP requests, initialize client like following
use std::path::PathBuf;
use reqwest::Client;
use reqwest_middleware::{ClientBuilder, ClientWithMiddleware};
use rvcr::{VCRMiddleware, VCRMode};
let mut bundle = PathBuf::from(env!("CARGO_MANIFEST_DIR"));
bundle.push("tests/resources/replay.vcr.json");
let middleware: VCRMiddleware = VCRMiddleware::try_from(bundle.clone())
.unwrap()
.with_mode(VCRMode::Record);
let vcr_client: ClientWithMiddleware = ClientBuilder::new(reqwest::Client::new())
.with(middleware)
.build();Now ClientWithMiddleware instance will be recording requests to a file
located in tests/resources/replay.vcr.json inside the project.
To use recorded VCR cassette files, replace .with_mode(VCRMode::Record)
with .with_mode(VCRMode::Replay), or omit it, since replay is used by default.
When replaying, rVCR can skip requests already found when searching for
subsequent requests (the default). To disable skipping requests,
which is useful, for example, if requests are done in parallel and responses
may come in random order, use .with_search(VCRReplaySearch::SearchAll).
Sometimes VCR files can be too large and this harder to maintain in a version control system.
To save some space and turn on bzip2 compression for artifacts,
use .compression(true) method of the builder.
