I’m only a few days old in this whiz-bang rails world, so bear with me.

I’m in the middle of running functional tests, I’ve got some assert  
statements that check for the presence of a various tags on the page…  
One of the tags being checked is a form, and assert\_tag checks that its  
:method =\> “POST”. Unfortunately, the autogenerated form shows the value  
“post”, and apparently that’s just too much different (the assert  
fails).

Is there a way to call a case-insensitive assert? Here’s the code in  
question:

assert\_tag “form”,  
:attributes =\> { :action =\> “/user/register”,  
:method =\> “POST” }

I realize I can just change the assert to check for “post” and  
everything will be peachy, but this seems like something that could  
cause me problems again down the road if I don’t figure it out now.

Thanks in advance.

You can give assert\_tag a regular expression instead of just a string  
(and assert\_select is often used instead of assert\_tag these days)

Doh. Thanks, and for the assert tip.

Cheers

I’m not really sure – the code is generated with form\_for, and while I  
would imagine that function will consistently generate a lower-case  
“post”, I’m not comfortable trusting the rest of the language (or  
myself) to stick with that convention.

The regular expression did it.

Can you improve the code so its case is consistent? That would seem to  
fix the  
root problem here…
