I am trying to use regular expressions in test cases and I am unable to get anything other than literal matching to work. Specifically, I am trying to check the output of:
print ("Hello World")
and I have set the regular expression to each of the following without success:
new RegExp(/Hello World/i);
Is this functionality working and I am missing some documentation?
Hey, can you please give us a Repl link so we can help you?
If this is Python, then regexes don't work like that so here's some quick documentation for you. https://docs.python.org/3/library/re.html
Please upvote my comment if it was helpful or useful in any way
Edit: To clarify, I can't provide a Repl link because it's not on a project, it's about a feature of Repl itself.
This has been driving me crazy, too, and I finally figured something out. I've gotten regular expressions to work, but I can't get flags to work.
In a Hello World assignment I got the following regular expressions tests to pass. Expected output is "Hello world!"
It seems that regular expressions work if you don't put the leading and trailing "/". But, this leads to the issue of how to add flags. I'd really like to be able to add flags like "i" for case-insensitivity. Here are some things I tried that didn't work. Maybe someone can figure something out.
RegExp("hello world!", "i")
RegExp('hello world!', 'i')
new RegExp('hello world!', 'i')
Regular expressions don't work properly (or not at all). I've tried several variations, with/without start/end "/" markers as well as lots of others...all based on Mozilla ECMA regex, as referenced in your documentation.
I have noticed that if I put incorrect regex (i.e. invalid), the system will hang when running the test. So, it looks like it's running SOME kind of regex algo...but it's just very poorly implemented/documented.
Please fix this as it is a vital part of your platform for us instructors.
I've taken most of regex out, and will likely delete the specific test so it doesn't cause a failure for my students...but here's the link so that an admin can look at the assignment and run a test regex.
