Work In Progress
Library provides functions for unit testing with human-readable syntax. Inspired by Nimble for Swift.
Using this library you will receive nice messages with data that used in test case, example:
rust
let result = vec![1, 2, 2];
expect!(result).to(be_equal_to([1, 2, 3]));
Test fails and gives us a message:
expected to be equal to <[1, 2, 3]>, got <[1, 2, 2]>
Note: You need to use
cargo test -- --nocaptureto see output from tests.
In Cargo.toml:
toml
[dev-dependencies]
expectest = "*"
In your crate: ```rust
extern crate expectest; ```
You can export all needed functions and types from prelude module:
rust
use expectest::prelude::*;
Use basic syntax to express expectations:
rust
expect!(...).to(...);
expect!(...).to_not(...);
expect!(...).not_to(...);
Note: You can use
expectfunction instead ofexpect!macro in that case you will not see file and line where the test fails.
For types that implement the PartialEq trait:
rust
expect!("hello".to_string()).to(be_equal_to("hello"));
There is a way to check if two float numbers are close each other:
rust
expect!(12.1_f64).to(be_close_to(12.0).delta(0.1));
With default delta equal 0.001:
rust
expect!(12.001_f64).to(be_close_to(12.0));
For types that implement the PartialOrd trait:
rust
expect!(1).to(be_greater_than(0));
Use following matchers: be_less_than, be_less_or_equal_to, be_greater_than, be_greater_or_equal_to
rust
expect!(9 == 9).to(be_true());
Use following matchers: be_true, be_false
