sweet

Very early stage warning! No ongoing maintenance is guaranteed

Basically a jest clone, the sweet crate will set you up with a beautiful test harness and intuitive matchers that are easy on the eyes.

Quickstart

1. edit cargo.toml

   [dev-dependencies]
   sweet = # current version here
   
   [[test]]
   name = "sweet"
   path = "test/sweet.rs"
   harness = false
   

2. create file test/sweet.rs

   #![feature(imported_main)]
   pub use sweet::*;
   
   sweet! {
   	it "works" {
   		expect(true).to_be_false()?;
   	}
   }
   

3. run these commands

   rustup default nightly
   cargo test --test sweet
   

Features

• Nested Tests

  • Sweet is designed to collect and run all tests in one go. All tests exposed in the sweet.rs file will be run:

     //test/sub_dir/some_test.rs
     sweet!{
     	it "works" {
     		expect(true).to_be_true();
     	}
     }
     //test/sub_dir/mod.rs
     mod some_test
     //test/sweet.rs
     #![feature(imported_main)]
     pub use sweet::*;
     mod sub_dir;
