(NOTE: this Beta variation may well include error. See http://saasbook.info for details.) A one-semester collage path in software program engineering targeting cloud computing, software program as a carrier (SaaS), and Agile improvement utilizing severe Programming (XP). This ebook is neither a step by step educational nor a reference booklet. as an alternative, our target is to deliver a various set of software program engineering subject matters jointly right into a unmarried narrative, support readers comprehend an important rules via concrete examples and a learn-by-doing technique, and train readers sufficient approximately every one subject to get them begun within the box. Courseware for doing the paintings within the ebook is obtainable as a digital laptop photograph that may be downloaded or deployed within the cloud. A loose MOOC (massively open on-line path) at saas-class.org follows the book's content material and provides programming assignments and quizzes. See http://saasbook.info for information.

In determine 6. five, why needs to the should_receive expectation in line 7 come prior to the publish motion in line nine? the expectancy must arrange a try double for find_in_tmdb that may be monitored to ensure it was once referred to as. because the put up motion is finally going to lead to calling find_in_tmdb, the double has to be manage prior to the put up happens, differently the genuine find_in_tmdb will be referred to as. (In this example, find_in_tmdb doesn’t even exist but, so the try out might fail therefore. ) Returning to our unique specfile skeleton from the directory in determine 6. 2, line 6 says that search_tmdb should still decide on the “Search effects” view for rendering. after all, that view doesn’t exist but, yet as within the first instance we wrote above, that needn’t cease us. is that this relatively valuable? because the default view depends upon conference over configuration, all we’re particularly doing here's checking out Rails’ integrated performance. but when we have been rendering one view if the motion succeeded yet a unique view for showing an mistakes, examples like this could ascertain that the proper view was once chosen. when you consider that we all know from bankruptcy three that the default habit of the strategy MoviesController#search_tmdb is to aim to render the view app/views/movies/search_tmdb. html. haml (which we created in bankruptcy 5), our spec simply must ensure that the controller motion will certainly try and render that view template. to do that we'll use the reaction approach to RSpec: when we have performed a get or put up motion in a controller spec, the article again via the reaction approach will comprise the app server’s reaction to that motion, and we will assert an expectation that the reaction may have rendered a specific view. this occurs in line 15 of determine 6. 6, which illustrates one other form of RSpec statement: item. should still match-condition. during this instance, match-condition is equipped by way of render_template(), so the statement is chuffed if the item (in this example the reaction from the controller motion) tried to render a specific view. we'll see using should still with different match-conditions. The adverse statement should_not can be utilized to specify that the match-condition shouldn't be actual. * * * http://pastebin. com/3HELV51D 1 require ’spec_helper’ 2 three describe MoviesController do four describe ’searching TMDb’ do five it ’should name the version procedure that plays TMDb seek’ do 6 fake_results = [mock(’movie1’), mock(’movie2’)] 7 motion picture. should_receive(:find_in_tmdb). with(’hardware’). eight and_return(fake_results) nine submit :search_tmdb, {:search_terms => ’hardware’} 10 finish eleven it ’should opt for the quest effects template for rendering’ do 12 fake_results = [mock(’Movie’), mock(’Movie’)] thirteen motion picture. stub(:find_in_tmdb). and_return(fake_results) 14 publish :search_tmdb, {:search_terms => ’hardware’} 15 reaction. should still render_template(’search_tmdb’) sixteen finish 17 it ’should make the TMDb seek effects on hand to that template’ 18 finish 19 finish * * * determine 6. 6: Filling out the second one instance. strains 11–16 exchange line eleven from determine 6.
