This is exactly what you have to write: test.name and test.category 
(assuming you did test = Test.new ... before)

Again: This is exactly what to do: test.name = ...

When you call

attr_accessor :name, :category

then Ruby creates getters and setters for @name and @category. To be 
more specific: Ruby creates two methods for @name, which are

def name()
  @name
end

def name=(value)
  @name = value
end

The same for @category. The first method simply returns the value of 
@name. If you leave out the parenthesis, the method call looks like 
you're accessing an attribute:

test.name  # actually a method call: test.name()

The second method allows you to change the value of the variable. Note 
the "=" in the method name. This allows you to use assignment syntax:

test.name = 'abc'  # actually a method call: test.name=('abc')
