litmus

a macro-free BDD test harness.
inspired by cucumber and rspec.

Why litmus

With litmus, you can ...

write tests declaratively
  with minimal overhead
   all without using macros.

Major design criteria

• works with cargo-test and cargo-nextest
• offers Gherkin ergonomics
• is fast

Quickstart

Add this to your Cargo.toml:

# ./Cargo.toml

[dev-dependencies]
litmus = "0.4.1"

Disable the default harness for your test targets:

# ./Cargo.toml

[[test]]
name = ...
path = ...
harness = false

For instructions on writing tests, refer to the section below.
