It's not perfectly clear what the best behaviour is here, but I think this is an improvement.

The problem is that in some cases RUST_BACKTRACE=1 is set, which changes the uninteresting parts of the output, which means the .run.stderr file doesn't match.

Other assert tests in tests/ui/macros/ instead use the error-pattern header to check the output of assertions. I didn't use that because it chops off whitespace from the start and end of the patterns, which means I couldn't precisely check for the expected + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0 output line.

In other words, a .run.stderr file over-specifies the expected output, while an error-pattern header under-specifies the expected output. I need something in between, that matches the assertion failed lines exactly, but ignores the backtrace lines.

IIRC, you can set a header like exec-env: RUST_BACKTRACE=0 or so? That'll disable the backtrace independent of runner environment.

The `\n` in the output is a little surprising. The next commit will deal with it.

The assertion in `assert-long-condition.rs` used to be fail like this, all on one line: ``` thread 'main' panicked at 'assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18\n + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0', tests/ui/macros/assert-long-condition.rs:7:5 ``` The `\n` and subsequent indent is because the condition is pretty-printed, and the pretty-printer inserts a newline. Printing the newline in this way is arguably reasonable given that the message appears within single quotes, which is very similar to a string literal. However, after the assertion printing improvements that were released in 1.73, the assertion now fails like this: ``` thread 'main' panicked at tests/ui/macros/assert-long-condition.rs:7:5: assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18\n + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0 ``` Now that there are no single quotes around the pretty-printed condition, the `\n` is quite strange. This commit gets rid of the `\n`, by removing the `escape_debug` done on the pretty-printed message. This results in the following: ``` thread 'main' panicked at tests/ui/macros/assert-long-condition.rs:7:5: assertion failed: 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 + 21 + 22 + 23 + 24 + 25 == 0 ``` The overly-large indent is still strange, but that's a separate pretty-printing issue. This change helps with rust-lang#108341.

Great suggestion, thank you. I have updated with this change.

Here's another example:

fn very_long_function_name(x: u32) -> u32 { x }

fn main() {
    assert!(
        {
            let x = 1;
            let y = 2;
            very_long_function_name(x) + very_long_function_name(y) 
        } == 
        {
            let x = 0;
            let y = 1;
            very_long_function_name(x) + very_long_function_name(y)
        }
    );
}

Previously it would produce a single line of output on failure:

assertion failed: {\n        let x = 1;\n        let y = 2;\n        very_long_function_name(x) + very_long_function_name(y)\n    } ==\n    {\n        let x = 0;\n        let y = 1;\n        very_long_function_name(x) + very_long_function_name(y)\n    }

Now it produces something much better:

thread 'main' panicked at s3.rs:4:5:
assertion failed: {
        let x = 1;
        let y = 2;
        very_long_function_name(x) + very_long_function_name(y)
    } ==
    {
        let x = 0;
        let y = 1;
        very_long_function_name(x) + very_long_function_name(y)
    }
