Macro snapbox::assert_data_eq

macro_rules! assert_data_eq {
    ($actual: expr, $expected: expr $(,)?) => { ... };
}

Check if a value is the same as an expected value

By default filters are applied, including:

• ... is a line-wildcard when on a line by itself
• [..] is a character-wildcard when inside a line
• [EXE] matches .exe on Windows
• \ to /
• Newlines

To limit this to newline normalization for text, call Data::raw on expected.

Effective signature

fn assert_data_eq(actual: impl IntoData, expected: impl IntoData) {
    // ...
}

Examples

let output = "something";
let expected = "so[..]g";
assert_data_eq!(output, expected);

Can combine this with file!

let actual = "something";
assert_data_eq!(actual, file!["output.txt"]);
