The smallest test reporter ever

cargo-smol takes the output of cargo test --format json and formats it into a small area.

note: smol requires -Z unstable-options until the json format is stablized.

Typically, smol is paired with watch so that it gets rerun whenever a file changes. Try this in your project: cargo watch -x smol.

If all of your tests are passing, this should show up:

If you have a test failure, you should see something like this:

smol will only show as many test cases as can fit into the size of the window it's in. Any additional tests will not be listed, but will be included in the test summary status line.

Current Release: v0.1.1

Technical Details

Something about the way cargo-watch works inhibits the ability to switch the terminal into raw mode. Because of this, we cannot have complete control over the terminal. We do our best, but there are probably bugs.

I know a couple of the test cases are currently failing.
