§Assertables: assert macros for better testing

Assertables is a Rust crate that provides many assert macros to improve your compile-time tests and run-time reliability.

§Introduction

The Assertables Rust crate provides many assert macros that can help you develop, test, and debug.

Test values with assert_lt, assert_gt, assert_in, …
Test groups with assert_all, assert_any, assert_iter, …
Test wrappers with assert_ok, assert_some, assert_ready, …
Test matching with assert_matches, assert_is_match, …
Test nearness with assert_approx, assert_abs_diff, …
Test programs with assert_command, assert_status, …
Many more below.

To use this crate, add it to your file Cargo.toml:

assertables = "9.8.2"

Benefits:

You will write better tests to improve reliability and maintainability.
You will handle more corner cases without needing to write custom code.
You will troubleshoot faster because error messages show more detail.

Learning: FAQ, docs, examples, changes, upgrades, developing.

Comparisons: more_asserts, cool_asserts, assert2, claims, etc.

§Examples

Examples with numbers:

let i = 1;
assert_lt!(i, 2);
assert_in_range!(i, 0..2);

Examples with strings:

let s = "hello";
assert_starts_with!(s, "h");
assert_is_match!(Regex::new(r"e.*o").unwrap(), s);

Examples with arrays:

let a = [1, 2, 3];
assert_contains!(a, &2);
assert_all!(a.into_iter(), |i: i32| i < 4);

§Forms

The Assertables macros have a variety of forms to help you write the tests that matter most to you.

All the macros have forms for an optional message:

assert_gt!(a, b) // default message
assert_gt!(a, b, "your text") // custom message

All the macros have forms for different outcomes:

assert_gt!(1, 2) // panic
assert_gt_as_result!(1, 2) // return Result
debug_assert_gt!(1, 2) // panic in debug mode

Many of the macros have a form “compare left item to right item” that compares items of the same kind, and a form “compare left item to right expression” that compares one item to any arbitrary expression:

assert_len_eq!(a, b) // a.len() = b.len()
assert_len_eq_x!(a, x)) // a.len() = x

Many of the macros has a “success return”, which means the macro returns data that you can optionally use for more testing.
