This is a fork of nextest which allows a group of tests to share a "server wrapper".

Basically a combination of a setup script and wrapper, which is useful if you're testing against a server and don't want to spin that up for every integration test.

We've built it at @comper-io so that we can spawn a server process that remains active as long as the client tests are being fired off. This allows us to stress test the server process and run all of our integration tests within about 50 seconds on a 16 core machine, of course at the cost of isolation between tests.

We like speed.

This is just for our own purposes and highly experimental. It's "weird" so we don't expect it to be upstreamed. Feel free to take inspiration from it.

Nextest is a next-generation test runner for Rust. For more information, check out the website.

This repository contains the source code for:

• cargo-nextest: a new, faster Cargo test runner
• libraries used by cargo-nextest:
  • nextest-runner: core logic for cargo-nextest
  • nextest-metadata: library for calling cargo-nextest over the command line
  • nextest-filtering: parser and evaluator for filtersets

The minimum supported Rust version to run nextest with is Rust 1.41. Nextest is not tested against versions that are that old, but it should work with any version of Rust released in the past year. (Please report a bug if not!)

The minimum supported Rust version to build nextest with is Rust 1.91. For building, at least the last 3 versions of stable Rust are supported at any given time.

See the stability policy for more details.

While a crate is pre-release status (0.x.x) it may have its MSRV bumped in a patch release. Once a crate has reached 1.x, any MSRV bump will be accompanied with a new minor version.

See the contributing guide for how to help out.
