# Tests

## Show the rustc command for UI tests

Add ` --test-args "--verbose"` to `./x.py test`.
Ignore failing test This test only fails with non-native 128-bit integers, but it will also fail with native 128-bit integers if we copy/paste it so that it's executed twice. Interestingly, wrapping the test in a loop won't make it fail. So, it could be due to stack space or unwinding in release mode. Also, the test only fails with -O2: ../cargo.sh rustc --bin test-rust -- -O It doesn't fail with -O3. 2023-10-17 06:57:56 -05:00			`# Tests`
