use philiprehberger_diff_assert::assert_eq_diff;
#[test]
fn my_test() {
let expected = "hello\nworld\nfoo";
let actual = "hello\neveryone\nfoo";
// Shows a colored diff on failure instead of raw Debug output
assert_eq_diff!(expected, actual);
}
Output on failure:
hello
- world
+ everyone
foo
Programmatic use
use philiprehberger_diff_assert::diff_strings;
let diff = diff_strings("line1\nline2", "line1\nline3");
