Method: Fit::FixtureLoader#find_class

Defined in:
lib/fit/fixture_loader.rb

#find_class(name) ⇒ Object

Try to load the named class. We first see if it’s already loaded by looking for the class name. If not, we convert the class name to a file name (by changing ‘::’ to ‘/’, then try to require that file. We then look for the constant again. This means that the class Example::Sqrt must be in the file Example/sqrt.rb or the file example/sqrt.rb.
