I’m trying to ensure that various fields are saved to the database  
without html, by stripping tags in before\_save. However I’m having  
trouble setting up the unit test for this and I’m not sure if it’s my  
code or my test that’s wrong.

The model code is:

def before\_save  
self.first\_name = strip\_tags(self.first\_name)  
self.last\_name = strip\_tags(self.last\_name)  
self.organisation = strip\_tags(self.organisation)  
end

The relevant part of my unit test is (obviously I’m doing for each item  
in the before\_save bit, but since it’s all the same I’m just showing the  
one):

```
c = Contact.new
c.first_name = "this"
c.last_name = "<html>that</html>"
c.organisation = "there"
c.email='removed_email_address@domain.invalid'
c.save

assert_match("that", c.last_name)

```

Problem is that if I do assert\_match(“that”, c.last\_name)  
it also matches.

What’s my problem? Is it the code or the test?

Also, could someone help me with an assert\_no\_match regexp. I hate  
regexps! I would like to do an assert\_no\_match with that -  
except I don’t know how to do a regular expression to check for an exact  
match with this.

Thanks to any help I can get!
