Having trouble testing :( "superclass mismatch" and can''t load "test_helper"

I''m having trouble testing my Rails 3 application.  Unit testing
doesn''t work.  If I try ruby article_test.rb directly, I get a "no
such file to load" error, and if I try rake test:units or ruby unit/
article_test.rb I get this odd "superclass mismatch for class
ArticlesController" error!

I''m hoping I can get this settled...
My test files were generated by the generator...

C:\Users\Family\workspace\jdrampage\test\unit>ruby article_test.rb

Did you look at your ArticlesController for clues?

Also, does your app function through the browser but not running the tests?

Would not hurt to copy your ArticlesController here, and maybe also your
Environment.rb

If you want to run a test directly like this you have to tell it to
include the test directory so it can find the helpers, so from the
root of your app
ruby -I test test/unit/article_test.rb

That is a capital i (for Include)

Okay - I guess that solves one of my problems in which I got the "no
such file to load -- test_helper" error.

Yes, running rails server works fine.  It''s the tests that give this
error.

Okay.  I''m in Rails 3, though, so environment.rb is probably useless
to look at...
Here''s the articles controller:

class ArticlesController < ApplicationController
  # GET /articles
  # GET /articles.xml
  def index
    @articles = Article.all(:limit => 6)

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @articles }
    end
  end

  # GET /articles/1
  # GET /articles/1.xml
  def show
    @article = Article.find(params[:id])
    @section = @article.section

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @article }
    end
  end

  # GET /articles/new
  # GET /articles/new.xml
  def new
    @article = Article.new

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @article }
    end
  end

  # GET /articles/1/edit
  def edit
    @article = Article.find(params[:id])
  end

  # POST /articles
  # POST /articles.xml
  def create
    @article = Article.new(params[:article])

    respond_to do |format|
      if @article.save
        flash[:notice] = ''Article was successfully created.''
        format.html { redirect_to(@article) }
        format.xml  { render :xml => @article, :status
=> :created, :location => @article }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @article.errors, :status
=> :unprocessable_entity }
      end
    end
  end

  # PUT /articles/1
  # PUT /articles/1.xml
  def update
    @article = Article.find(params[:id])

    respond_to do |format|
      if @article.update_attributes(params[:article])
        flash[:notice] = ''Article was successfully updated.''
        format.html { redirect_to(@article) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @article.errors, :status
=> :unprocessable_entity }
      end
    end
  end

  # DELETE /articles/1
  # DELETE /articles/1.xml
  def destroy
    @article = Article.find(params[:id])
    @article.destroy

    respond_to do |format|
      format.html { redirect_to(articles_url) }
      format.xml  { head :ok }
    end
  end
end

I hope this helps.  Though this class is pretty standard...

Re: Having trouble testing :( "superclass mismatch" and can''t load "test_helper"

I figured it out.

I simply forgot to put "Admin::" for the articles controller in the
admin namespace.  Making the controllers start with "class
Admin::ArticlesController" resolved the issue.
Of course I had to add "Admin:: to any other controllers in the admin
namespace that were missing it too.

:)
