Currently we can't automatically enforce formatting on tests (see #125637), but we can at least keep things relatively tidy by occasionally running the formatter manually. This was done by temporarily commenting out the `"/tests/"` exclusion in `rustfmt.toml`, and then running `x fmt tests/coverage` and `x test coverage --bless`.
