Hi,

I use an regular expression to verify that my string in time\_on\_site is  
correct. This works when the string match, but if it doesn’t the test  
get hanged. So I need to quit(ctrl+c) the script and also close ruby.exe  
\*32 in Task manager. Any ides how I can handle this?

time\_on\_site.should match(/^00:[0-5][0-9]$/)

Best regards  
Mattias

If I use below it returns correct output. Can I use something similar  
with Rspec so the test fails if its not true?

if time\_on\_site =~ /^00:[0-5][0-9]$/  
puts “# Successful match”  
else  
puts “# Match attempt failed”  
end
