Change the contents of the Say_controller.rb file in the Appcontrollers directory to the followi

We've already completed a simple shopping cart, and from this start we'll see how to test in rails. When we created the shopping cart program in our depot directory, there is already a test directory, which is for us to test preparation. So far, we've seen that the fixtrues and Functional,unit directories inside have a test file that corresponds to the controller and model. We first Test products this model. Code test\unit the product_test.rb file i

Let's take a look at some tips for debugging this time. First, and most importantly, writing test code, writing unit tests and functional tests in rails is simple, using them to reduce the rate of bugs, or to avoid bugs in your previous code. The test code tells you what works and what doesn't, and the test code helps you isolate the problematic code, because sometimes the bug doesn't show up quickly. If the problem occurs in a model, we can use th

Rails is for Web projects and you have to think about the large amount of traffic, so let's take a look at how rails performs performance testing. 1. To perform performance testing, we first have to imitate a large number of data, we now know that in the test/fixtures/directory in the Yml file to add our test data, when the test run, the data will be loaded into the database.

At this point, the implementation of this shopping cart is complete. Now we can use Rdoc in ruby to generate documents for our program, just like dotnet, java, and python, rdoc can extract the comments before class and method declaration in our code to generate a document. For our depot program, run the rake appdoc command in the rails command line, After that, you can view the generated d

In the previous section, we demonstrated how to build a list of items, and this time we built a simple shopping cart based on the previous content. 1. First we want to create a table that holds customer shopping information: Database scripts: drop table if exists line_items; CREATE TABLE Line_items ( ID int not NULL auto_increment, product_id int not null, quantity int NOT null DEFAU Lt 0, unit_price decimal (10,2) NOT NULL, constraint fk_items_product foreign key (product_id) references Pro

The last Test Modeul problem has not been resolved, but the following to continue, this time to test controller. 1. In the test\functional directory, rails has generated a corresponding test file for our controller, and note that Application_controller does not generate test files. Let's take control of the login Logincontroller as an example, open the LOGIN_CONTROLLER_TEST.RB, which reads as follows: Require File.dirname (__file__) + '/... /test_h
