Testing Frameworks for Ruby on Rails

As an open source and full stack framework, Ruby on Rails (RoR) is used widely by developers to rapidly create a variety of web applications. RoR supports some of the widely used software engineering patterns and principles. So it becomes easier to easily accomplish several tasks. The web application development framework is further designed with integrated testing support.

The developers can easily write test by using the skeleton test code produced by RoR. Along with ensuring that the code adheres to the predefined functionality after major modifications, Rails also allow developers to test the application’s response by simulating browser requests. However, the developers can still use testing frameworks for Ruby on Rails to effectuate application testing.

5 Widely Used Testing Frameworks for Ruby on Rails

1) Cucumber
Despite being written in Ruby, Cucumber can be used effectively to test web applications written in several programming languages like C#, Java, Ruby, Python. So the testing framework can be used by QA engineers without knowing Ruby programming in detail. Cucumber is designed with features that execute plain-text functional descriptions as automated tests. Along with being an efficient testing tool, Cucumber also supports behavior-driven development (BDD). Thus, it becomes easier for both technical and non-technical stakeholders to verify the test code written before the original testing starts. You can use the testing framework after installing and activating the Cucumber gem inside your project.

2) RSpec
Like Cucumber, RSpec is also a testing tool that supports behavior-driven development. So the domain experts and business analyst can analyze the test code according to the features and use of the application. The testing framework for Ruby also comes with a set of features to make test driven development more productive. While testing a Ruby application using RSpec, the testing professional can avail rich command line program, flexible and customizable reporting, extensible expectation language, textual descriptions of examples and groups along with built-in mocking/stubbing framework.

3) Test::Unit
You can always use Test::Unit to test web applications by implementing the xUnit testing framework for Ruby. Once you started writing Ruby code, you will surely come across Test::Unit. Despite being bundled with Ruby, the unit testing framework is not a static part of RoR. The professionals writing new test code are further recommended to use MiniTest instead of Test::Unit.

4) Shoulda
Shoulda was originally designed as a unit testing tool. But it can be used to test Ruby applications by attaching the shoulda gem to the project. Thus, the Shoulda tests need to be added on to the Test::Unit framework. The shoulda gem is a meta gem with two dependencies, i.e., shoulda-context and shoulda-matchers. While testing Ruby applications, testing professionals can use these distinct dependencies to write test cases according to the requirements of the project.

5) Spork
Spork is used widely as a testing server to evaluate the Ruby applications. Each time you run a test, a copy of the server is forked. Thus, you can use RoR to reload your files without uploading them constantly. Further, Spork runs in a solid way, without being corrupted over time. Also, the testing server is compatible with several Ruby testing frameworks including Cucumber, RSpec and Test::Unit. Likewise, it also supports a number of application development frameworks. So it becomes easier for you to test different modules and meta programming.

On the whole, programmers have option to choose from a variety of testing frameworks for Ruby on Rails. Most of these frameworks are designed with features to facilitate a certain type of testing. So the developers must decide the Ruby on Rails testing framework according to the needs and objectives of the project.

3 Things Programmers Should Definitely Know About ROR?

Ruby on Rails is fast gaining a lot of popularity both amongst the startup companies as well as those which have been doing business for years and are seasoned campaigners. However, ROR and its acceptability have gone far beyond this early phase of mere acceptability. At present, big players in the online shopping fraternity are extensively using ROR also, for the majority of their newer as well as upcoming projects, and when we speak of acceptability, it is not only these online shopping companies which are accepting ROR. The major IT companies from all around the globe are more and more using Ruby on Rail for the majority of their enterprise projects. Hence, there is no prize in guessing that programmers need to know a lot of things about ROR if they are looking forward to do something really ‘big’ in their programming careers.

Ruby on Rails development India

Technically speaking, ROR is basically made up of two distinctive parts – language and the framework. It is a general programming language that has not got anything to do with any specific web application. In fact, it is this generalized character that makes this open source application framework so very adorable nowadays. Ruby can be used without using the rails and can be used as a stand-alone application program, for scripting various server administration tasks even for those applications that do not use Rails.

Now let us get into the three most important aspects of ROR that programmers must need to be familiar with.

New Query Engine
ROR comes up with an amazing state of the art query engine that provides the users the option of easily retrieving back the data that is needed. It also offers a seamless flexibility to the controller code. These changes show up their efficacy as well as importance in a number of places, though the most important privilege that it offers is evident when it comes to fetching the data in the controller. This ‘find method’ is used in version 2 for retrieving the data and for passing in the arguments to specify various conditions, limits, grouping, and for other query information.

Default Settings
In ROR, a Mailer is actually a class that can have a number of methods. Each of these methods is specifically designed to generally configure as well as send emails. Previously, the user had to set all the required parameters for each of the emails separately in each of these methods. However, in version 3 things are more advanced and defaults can be specified and can optionally be overwritten in each of the methods.

Dependency Management
One of the mainstays of ROR framework is its wide range of gems that available to be used by the developers or programmers. Knowing about these gems will make the task of the developers significantly easier irrespective of the fact whether it is for authentication or for handling various transactions or managing file uploads or anything else. These gems will surely come to the aide while resolving various issues.

In fact, issues can obviously arise. However, a sound knowledge about these gems will enable the developers who are working in various environments will help design as well as develop ROR in a seamless way. Again, when it comes to solving various types of issues along with handling situations, Rail 3 has the bundle gem that helps in managing the discrepancies.

These are only some of the features of the ROR 3 that the developers need to know in order to be able to work on the application in a seamless way. A thorough knowledge about these three aspects will surely help the developers in a great way and that is the reason, knowledge about these three aspects is an absolute ‘must’.

Best Practices for Ruby on Rails Applications

Developers across the world rely on Ruby on Rails to build robust and high quality web applications within a shorter timeframe. In addition to being highly flexible and compatibility with multiple platforms, the web application development framework further makes it easier for developers to adopt agile development and avoid repetitive coding. However, the developers also need to understand and implement a number of best practices for Ruby on Rails applications write and maintain their code in a cleaner and efficient way.

Widely Used Coding Best Practices for Ruby on Rails Development

1) Bundle Your Code into Plugins and Gems
Expert Ruby on Rails developersThe web application framework allows developers to access a variety of rubygems. So the developer can always use the rubygems developed by others to solve relatively general problems. You can always consider reusing the existing code by extracting it into a plugin or gem. Also, the gem or plugin can be used more widely. You can further simplify the application design by extracting code from it. Similarly, you can consider using existing gems and plugins to avoid writing lengthy code.

2) Shift Logic Code from Controllers to Model
You can always optimize your coding by having most of the logic code on the models. It is also a good idea to move the logic code from controllers to model. The coding can be further optimized by keeping the controllers clean as these controllers remain loaded constantly. On the other hand, the models are loaded only based on requirements. So your application will use less memory when the logic code is moved from controllers to model.

3) Use Scope Access
The availability of an object can be easily determined by using scope access. Instead of using Finders, you can use scope access to gather the information directly from the object. Also, the coding can be modified to use Scope access for most of the objects created for the current project. Thus, code access will help you in reducing the number of calls, and faster execution.

4) Use Local Variables rather than Instance Variables
Ruby on Rails enables developers to access the @variable in views. Many developers even use the element in various parts of the code without evaluating the requirements. You can always optimize the coding by eliminating the instance variables. It is also important to check the instance variables, and convert them into local variables. The local variables can be further transferred smoothly from the view to the partial as part of :locals.

5) Eliminate Empty Helpers
You can always move all the Ruby code to the helpers by creating relevant methods. These methods can be called from the view to effectuate your coding. However, you must remember that additional helpers are created each time you create controllers. Despite being concise, the helpers will be loaded each time the application is launched. So the additional helpers can affect the loading time of the application negatively. You must check these helpers, and remove the helpers without any method to reduce the loading time of your Ruby application.

6) Organize Your Logic through Non-Database-Backed Models
While adopting the MVC approach, each developer has option to use both database-backed and non-database-backed models. Like other MVC development frameworks, Ruby on Rails also allows developers to use both models. However, you can always opt for the non-database-backed model to keep your logic clean and organized. Also, the virtual models can be used to adopt a RESTful controller design that facilitates data access from multiple sources. These practices will make it easier for the controller code to interact with these models.

Each Ruby developer has options to implement many coding best practices and techniques to shorten development cycles. At the same time, he can further create new best practices for Ruby on Rails applications based on his own experience and skills.
