Test on last line of a file missing failure message

[benhutchison]

I've observed that when a munit test defined on the last line of a test file fails, the failure message is missing all the details. (Using Dotty 0.27). If the tests are re-ordered, the message is displayed normally.

Using debugger I narrowed down what's happening. This line expects slice array to have length 3, In my case, it has length 2.

So it drops through to the end of method and returns empty String as fail message. That in turn is because if location.line is the last line in lines, then taking a slice to location.line + 1 wont add another line to the slice here

Perhaps this shows up more with dotty's optional braces where the test is on the last line of the file?

Workaround: add a comment to line after the last test

Thank you for reporting! I am able to reproduce. I opened #226 with a fix for this bug.
