questions on panda for now, will finish rest too

[mikeadeleke]

I will do Tiger and Eagle after Panda.

Cannot see why why features 7 and 8 will not pass!

There's no assertion here, right? What are you testing here?

[mikeadeleke]

Just put in an assertion

[jwo]

Where is your "AverageGrade" class defined?

[jwo]

both your RSpec and cucumbers fail with these two errors:

1. undefined local variable or method `class_total'
2. undefined local variable or method `average_grade'

I recommend you get your rspec passing first, and then look at cucumber.

Final suggestion: you are submitting many, many episodes at once. That can't be easy to keep straight in your head. Skills build on each other. I recommend you pick one to get working, then choose another.

[mikeadeleke]

Right on.

[mikeadeleke]

The only thing not passing in my Rspec is the average_grade method that is clearly defined.

P.S. From now on I will look to complete one assignment at a time. Good call.

The only thing not passing in my Rspec is the average_grade method that is clearly defined.

OK, so there are a couple of problems in your code. Let's start with the exception:

1) AverageGrade should view average grade for the class
     Failure/Error: average_grade.average.should eq(class_grade/class_total)
     NameError:
       undefined local variable or method `average_grade'
     # ./spec/teacher_spec.rb:25

It's saying we are calling average_grade when it hasn't been defined. It also tells us that teacher_spec line 25 is the offending line. Let's take a look:

describe AverageGrade do
  it "should view average grade for the class" do
    average_grade.average.should eq(class_grade/class_total)
  end
end

Here you are calling average on an object named average_grade, but average_grade does not exist yet. Looking at the code, you either needed to do one of these:

describe AverageGrade do
  let(:average_grade) { AverageGrade.new }
  it "should view average grade for the class" do
    average_grade.average.should eq(class_grade/class_total)
  end
end

describe AverageGrade do
  it "should view average grade for the class" do
    AverageGrade.new.average.should eq(class_grade/class_total)
  end
end

[jwo]

OK, so let's say you do that... Then it will fail because the AverageGrade class is not setup correctly. Let's look at it

class AverageGrade
  def initialize 
    @average_grade = average_grade
    @class_total = class_total
    @class_grade = class_grade
  end
  #...
end

After you do AverageGrade.new, this class will have 3 variables all set to nil: @average_grade, @class_total, @class_grade

You probably wanted those as inputs to the class, but you're missing the parameters on your initialize method.

[mikeadeleke]

Hmmm. Now I am getting

wrong number of arguments (0 for 3)

So now I think I should be making a method housing AverageGrade.new

[jwo]

yeah, check out my comments here: #4 (comment)

[jwo]

And more specifically, if you have a method with (average_grade, class_total, class_grade), you need to pass in the average_grade, class_total, and class_grade
