Fixes #10940.

This functionality is covered by an existing test that only needed minor updates to match new output. There were a couple of identical lines in the output used for text matching, so I added numbers to disambiguate.

Let me know if there are any suggestions or changes needed.

Hi @brl0 , thanks for the PR!

Here is the output from this branch for test_verbose_skip_reason:

It does not look like it was doing what was intended, or am I missing something?

Not sure "wrap" is appropriated, given "wrap" in this contents is to preserve the text, but wrapping it around at certain width (for example 70). I think what we are doing here is actually truncating, so perhaps truncate_write or something would be more appropriate?

Happy to rename to whatever, but in this case, the new method is only wrapping text. The truncated output you saw was unmodified behavior due to the test testing multiple outputs.
I'm not particularly satisfied with the name because I'm not sure that it feels sufficiently conventional. Perhaps write_wrapped_text or something similar would be better?

Indeed, I misunderstood the output hence my misguided suggestion. wrap_write is fine, thanks! 👍

@nicoddemus,

Thanks for taking a look.

The test test_verbose_skip_reason runs pytest twice, once with -v, and once with -vv. The output you provided was from the first run, which is less verbose, hence the truncation. I modified the expected output for the second run to expect the output to continue onto a new line in the middle of the output. This comment annotates that modification to help show more clearly that the modified test does check for the changed behavior.
Hopefully that makes sense, but let me know if it needs further clarification or changes to make it more clear. For example, we could break the runs into two separate tests, and move the common inputs and outputs into a fixture rather than the test body.
