Assertables: Rust crate of “assert” macros for testing

The assertables Rust crate provides many “assert” macros to help with compile-time testing and run-time reliability

Crate: https://crates.io/crates/assertables

Docs: https://docs.rs/assertables/

Repo: https://github.com/sixarm/assertables-rust-crate/

Highlights

Value macros such as: assert_gt!(value1, value2) which means value1 > value2.
Set macros such as: assert_set_subset!(set1, set2) which means set1 ⊆ set2.
Function macros such as: assert_fn_eq_other!(function, input1, input2) which means `function(input1) == function(input2)
Reader macros such as: assert_read_to_string_eq_other!(reader1, reader2) which means reader1.read_to_string() == reader2._to_string()
Commmand macros such as: assert_command_stdout_eq!(command, substr) which means `String::from_utf8(command.output().ap().stdout).unwrap() == string.

Naming conventions

Abbreviations:

eq (equals) and ne (not equals)
lt (less than) and le (less than or equal to)
gt (greater than) and ge (greater than or equals).

Shorthands:

reader means implements .read_to_string(…) such as std::io::Read.
matcher means implements .is_match(…) such as regex::Regex.
containee means usable inside .contains(…) such as a std::string::String substring.
set means a collection such as ::std::collections::BTreeSet.
bag means a collection such as ::std::collections::BTreeMap with key counts.

Forms for panic! or Result Err()

The macros have forms for immediate interrupts or returning results:

assert_gt!(a, b) => () or panic!(…)
assert_gt_as_result!(a, b) => Result Ok(()) or Result Err(…)

Forms for default messages or custom messages

The macros have forms for default messages or custom messages.

Example:

assert_gt(1, 2) => panic!("assertion failed: assert_gt(1, 2)…")
assert_gt(1, 2, "lorem ipsum") => panic!("lorem ipsum")

assert_* for values

Compare values.

assert_eq!(a, b) ~ a == b
assert_ne!(a, b) ~ a != b
assert_lt!(a, b) ~ a < b
assert_le!(a, b) ~ a <= b
assert_gt!(a, b) ~ a > b
assert_ge!(a, b) ~ a >= b

assert_set_* for set collection comparisons

These macros help with comparison of set parameters, such as two arrays or two vectors. where the item order does not matter, and the item count does not matter. The macros convert inputs into HashSet iterators.

assert_set_eq!(a, b) ~ set a == set b
assert_set_ne!(a, b) ~ set a != set b
assert_set_subset!(a, b) ~ set a ⊆ set b
assert_set_superset!(a, b) ~ set a ⊇ set b
assert_set_joint!(a, b) ~ set a is joint with set b
assert_set_disjoint!(a, b) ~ set a is disjoint with set b

assert_bag_* for bag collection comparisons

These macros help with comparison of bag parameters, such as comparison of two arrays or two vectors, where the item order does not matter, and the item count does matter. The macros convert inputs into HashMap iterators.

assert_bag_eq(a, b) ~ bag a == bag b
assert_bag_ne(a, b) ~ bag a != bag b
assert_bag_subbag(a, b) ~ bag a ⊆ bag b
assert_bag_superbag(a, b) ~ bag a ⊇ bag b

assert_fn_* for function return comparisons

assert_fn_ne_other!(f, a, b) ~ f(a) != f(b)
assert_fn_lt!(f, a, b) ~ f(a) < v
assert_fn_lt_other!(f, a, b) ~ f(a) < f(b)
assert_fn_le!(f, a, b) ~ f(a) <= b
assert_fn_le_other!(f, a, b) ~ f(a) <= f(b)
assert_fn_gt!(f, a, b) ~ f(a) > b
assert_fn_gt_other!(f, a, b) ~ f(a) > f(b)
assert_fn_ge!(f, a, b) ~ f(a) >= b
assert_fn_ge_other!(f, a, b) ~ f(a) >= f(b)

assert_fn_ok_* for function Ok() comparisons

assert_fn_ok_eq!(f, a, b) ~ f(a).unwrap() == b

assert_fn_ok_gt!(f, a, b) ~ f(a).unwrap() > b
assert_fn_ok_gt_other!(f, a, b) ~ f(a).unwrap() > f(b).unwrap()

assert_fn_err_* for function Err() comparisons

assert_fn_err_eq!(f, a, b) ~ f(a).unwrap_err() == b
assert_fn_err_eq_other!(f, a, b) ~ f(a).unwrap_err() == f(b).unwrap_err()

assert_fn_err_ge_other!(f, a, b)~ f(a).unwrap_err() >= f(b).unwrap_err()

assert_read_to_string_* for std::io::Read comparisons

assert_command_ for process command comparisons

Using standard output a.k.a. stdout:

assert_command_stdout_eq_other!(command, command) ~ String::from_utf8(command.output().unwrap().stdout).unwrap() == String::from_utf8(command.output().unwrap().stdout).unwrap()
assert_command_stdout_contains!(command, containee) ~ String::from_utf8(command.output().unwrap().stdout).unwrap().contains(containee)
assert_command_stdout_matches!(command, matcher) ~ regex.captures(String::from_utf8(command.output().unwrap().stdout).unwrap())

Using standard error a.k.a. stderr:

assert_command_stderr_eq!(command, value) ~ String::from_utf8(command.output().unwrap().stderr).unwrap() == value
assert_command_stderr_eq_other!(command, command) ~ String::from_utf8(command.output().unwrap().stderr).unwrap() == String::from_utf8(command.output().unwrap().stdout).unwrap()
assert_command_stderr_contains!(command, containee) ~ String::from_utf8(command.output().unwrap().stderr).unwrap().contains(containee)
assert_command_stderr_matches!(command, matcher) ~ regex.captures(String::from_utf8(command.output().unwrap().stderr).unwrap())
