I want to do something like
assert_match /blah blah blah #{@user}/, @some_text but I'm not having any luck with it working.
What am I doing wrong here?

There is the regex constructor which takes a string, so you can build your regex string which includes variables and then pass it to the Regex cosntructor.
=~ is Ruby's pattern-matching operator. It matches a regular expression on the left to a string on the right. If a match is found, the index of first match in string is returned. If the string cannot be found, nil will be returned.
A regular expression is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings. Ruby regular expressions i.e. Ruby regex for short, helps us to find particular patterns inside a string. Two uses of ruby regex are Validation and Parsing.
That is the correct way to insert a variable into a regex:
irb(main):001:0> a='Hi' => "Hi" irb(main):002:0> b=/Not #{a}/ => /Not Hi/ So your problem is likely that the assert is failing because of a bad match. Check the value of @user and @some_text and try http://rubular.com to come up with a matching regexp
