Morq Crate: https://crates.io/crates/morq

Grammar

Since we are using a macro here, you need to wrap the following rules in morq! macro.

Example:

morq!(
  expect(3).to.be.an(i32);
);

Chains

You use following chains to make the assertions more user friendly and readable.

• to
• be
• have

Equal

expect(30).to.be.equal(10 * 3);
expect(3).to.be.equal(1 + 2);

Close

To compare two given float values

expect(3f32).to.be.close(3.0001f32);
expect(3f32).to.be.close_to(3.0001f32);

Not

Negates the chain.

expect(30).to.not.be.equal(10);
expect(3).to.not.be.equal(1);
expect(vec![1, 2, 3]).to.not.be.a(Vec<char>);

A / An

To check the data type.

expect(30).to.be.an(i32);
expect("hola".to_string()).to.not.be.a(f32);
expect(vec![1, 2, 3]).to.be.a(Vec<i32>);

Empty

To check and see if the iterator is empty or not

expect(vec![1, 2, 3]).to.not.be.empty();
expect(0..2).to.not.be.empty();

LengthOf

To check the count of elements in an iterator

expect(vec![1, 2, 3]).to.not.have.length_of(1usize);
expect(0..3).to.have.length_of(3usize);

Contain

Given iterator must contain the element

expect(vec![1, 2, 3]).to.contain(2);
expect(vec![false, false]).to.not.contain(true);

Ok / Err

To check a Result enum

let res: Result<String, String> = Ok(format!("boo"));

morq!(
    expect(res).to.be.ok();
);

let res: Result<String, String> = Err(format!("boo"));

morq!(
    expect(res).to.be.err();
);

Of course, you can combine it with not:

let res: Result<String, String> = Err(format!("boo"));

morq!(
    expect(res).to.not.be.ok();
);

Roadmap

• Adding more chain rules

• Adding more assert (terminal)

• Ability to add two or more asserts in one chain:

  expect("hello").to.be.equal("hello").and.not.be.a(i32);
