[rust-dev] A shiny test framework

[Vladimir Pouzanov]

I've just published a tiny test framework: shiny at
https://github.com/farcaller/shiny. It's best used with hamcrest-rust.

This library exists because I find it ugly to redefine all the
initialisation code in every test case and I can't simply move it to a
function due to problems with moving [T] out.

Here's how shiny looks:

#[cfg(test)]
mod test {
describe!(
before_each {
let awesome = true;
}

it "is awesome" {
assert!(awesome);
}

it "injects before_each into all test cases" {
let still_awesome = awesome;
assert!(still_awesome);
}
)
}

Dude, that's pretty much rspec ;) sweet!

Nice to see an RSpec-like test framework and Hamcrest assertions/matchers
for Rust!

One note on why there's no after_each:

You cannot really make sure that the epilogue is being called, so if you
need to do anything after your test case, use RAII in before_each.

Could you use RAII to call a lambda?

It's great to see Hamcrest ported to Rust.

Awesome! I'm glad to see people extending Rust's testing infrastructure
with more expressive frameworks (I assume this translates to `#[test]`
fns under the hood?).

Exactly. That actually complicates `context` support a bit, as shiny needs
to create nested modules. That would require forwarding all the views into
child modules (as they are transparent for end developer).
