I'm not a ruby expert and may be this will seem a silly question...but I'm too courious about an oddity (I think) I've found in RSpec matcher called match.
You know match takes in input a string or a regex. Example:
"test".should match "test" #=> will pass
"test".should match /test/ #=> will pass
The strange begins when you insert special regex characters in the input string:
"*test*".should match "*test*" #=> will fail throwing a regex exception
This means (I thought) that input strings are interpreted as regex, then I should escape special regex characters to make it works:
"*test*".should match "\*test\*" #=> will fail with same exception
"*test*".should match /\*test\*/ #=> will pass
From this basic test, I understand that match treats input strings as regular expressions but it does not allow you to escape special regex characters.
Am I true? Is not this a singular behavior? I mean, it's a string or a regex!
EDIT AFTER ANSWER:
Following DigitalRoss (right) answer the following tests passed:
"*test*".should match "\\*test\\*" #=> pass
"*test*".should match '\*test\*' #=> pass
"*test*".should match /\*test\*/ #=> pass

RSpec is a testing tool for Ruby, created for behavior-driven development (BDD). It is the most frequently used testing library for Ruby in production applications. Even though it has a very rich and powerful DSL (domain-specific language), at its core it is a simple tool which you can start using rather quickly.
The word describe is an RSpec keyword. It is used to define an “Example Group”. You can think of an “Example Group” as a collection of tests. The describe keyword can take a class name and/or string argument.
RSpec::Expectations provides a simple, readable API to express the expected outcomes in a code example. To express an expected outcome, wrap an object or block in expect , call to or to_not (aliased as not_to ) and pass it a matcher object: expect(order. total).
before(:all) runs the block one time before all of the examples are run. before(:all) sets the instance variables @admission, @project, @creative, @contest_entry one time before all of the it blocks are run. However, :before(:each) resets the instance variables in the before block every time an it block is run.
What you are seeing is the different interpretation of backslash-escaped characters in String vs Regexp. In a soft (") quoted string, \* becomes a *, but /\*/ is really a backslash followed by a star.
If you use hard quotes (') for the String objects or double the backslash characters (only for the Strings, though) then your tests should produce the same results.
