  its('stdout') {should match (/^'sql-(\d)+.log'/)}
end

Answer 1

This regex /^'sql-(\d)+.log'/ doesn't match this string sql-20201212.log. You can try it out on https://regexr.com/

There are a few problems with your regex:

• ' is in your regex but not in your string
• . matches any character expect line breaks, perhaps you want to match only a dot(?), if so, then you'd need to e.g. escape it \.
• you probably don't need to have \d in a group (())

So, this regex ^sql-\d+\.log$ would match sql-20201212.log string. I also added $ to match the end of the string.
