## Editing and updating the reference files

If you have changed the compiler's output intentionally, or you are making a new
test, you can pass `--bless` to the test subcommand. E.g. if some tests in
`tests/ui` are failing, you can run
test, you can pass `--bless` to the test subcommand.

As an example,
if some tests in `tests/ui` are failing, you can run this command:

```text
./x test tests/ui --bless
```

to automatically adjust the `.stderr`, `.stdout` or `.fixed` files of
all tests. Of course you can also target just specific tests with the
`--test-args your_test_name` flag, just like when running the tests.
It automatically adjusts the `.stderr`, `.stdout`, or `.fixed` files of all `test/ui` tests.
Of course you can also target just specific tests with the `--test-args your_test_name` flag,
just like when running the tests without the `--bless` flag.
