What Is The Difference Between Rspec And Cucumber?

The main difference between RSpec and Cucumber are the business readability factor. Cucumber’s main draw is that the specification (features) are separate from the test code, so your product owners can provide or review the specification without having to dig through code.

What is RSpec used for?

RSpec is a testing tool for Ruby, created for behavior-driven development (BDD). It is the most frequently used testing library for Ruby in production applications. Even though it has a very rich and powerful DSL (domain-specific language), at its core it is a simple tool which you can start using rather quickly.

Is RSpec BDD or TDD?

RSpec is a Behavior-Driven Development tool for Ruby programmers. BDD is an approach to software development that combines Test-Driven Development, Domain Driven Design and Acceptance Test-Driven Planning.

Is RSpec a framework?

RSpec is a testing framework, so we first need to understand what a test is. If you’re a developer, then you’ve already performed software tests, whether you realize it or not.

Is RSpec a language?

RSpec is a computer domain-specific language (DSL) (particular application domain) testing tool written in the programming language Ruby to test Ruby code. It is a behavior-driven development (BDD) framework which is extensively used in production applications.

What is example in RSpec?

The word it is another RSpec keyword which is used to define an “Example”. An example is basically a test or a test case. Again, like describe and context, it accepts both class name and string arguments and should be used with a block argument, designated with do/end.

Is RSpec a unit test?

RSpec is a unit test framework for the Ruby programming language. RSpec is different than traditional xUnit frameworks like JUnit because RSpec is a Behavior driven development tool. What this means is that, tests written in RSpec focus on the “behavior” of an application being tested.

Is cucumber BDD or TDD?

Cucumber is an automation tool used for automating acceptance tests that are written in BDD(Behaviour driven development) style, in the form of features. In cucumber we have two types of files – a feature file and a step definition file.

Why is BDD better than TDD?

BDD is in a more readable format by every stakeholder since it is in English. Unlike TDD, test cases are written in programming languages such as Ruby and Java. BDD explains the behavior of an application for the end-user while TDD focuses on how functionality is implemented.

Can we use TDD and BDD together?

Short answer, yes.

How do I run a test in RSpec?

To run a single Rspec test file, you can do: rspec spec/models/your_spec. rb to run the tests in the your_spec. rb file.

Is cucumber Ruby based?

Cucumber is a test framework for behavior-driven Ruby development. Cucumber scenarios are written using the Gherkin syntax and stored in . feature files. Each scenario has multiple steps that link to step definitions representing Ruby blocks.

Is RSpec open source?

Owl – Open Source RSpec Test Reporting Tool. Owl is an open source tool used for the reporting and presentation of tests results achieved using the RSpec open source testing tool. It stores the test results in a PostgreSQL database and provides features to report them.

How do I run all RSpec?

How do I run RSpec tests in Rails?

1. Everything at once: bundle exec rspec . This runs all your tests.
2. One RSpec package: bundle exec rspec ./spec/models. This runs all model specs.
3. One RSpec file at a time: bundle exec rspec ./spec/models/story_spec. rb .
4. One by one: bundle exec rspec ./spec/models/story_spec. rb:10.

What is BDD approach in testing?

What is BDD (Behavior-Driven Development)? Behavior-driven development is a testing practice that follows the idea of specification by example (e.g., Test-Driven Development [TDD]). The idea is to describe how the application should behave in a very simple user/business-focused language.

How do I set up RSpec?

Setting up Rspec

1. Step 1 — Delete Any Existing Test Folders. If I’ve generated a new rails app using rails new without using any additional flags, I remove the app/test directory:
2. Step 2 — Add Gems.
3. Step 3 — Run Rspec Generator.
4. Step 4 — Configure Rspec.
5. Step 5 — Write Tests.

What is double in RSpec?

RSpec features doubles that can be used as ‘stand-ins’ to mock an object that’s being used by another object. Doubles are useful when testing the behaviour and interaction between objects when we don’t want to call the real objects – something that can take time and often has dependencies we’re not concerned with.

What is context in RSpec?

According to the rspec source code, “context” is just a alias method of “describe”, meaning that there is no functional difference between these two methods. However, there is a contextual difference that’ll help to make your tests more understandable by using both of them.

What is RSpec shared examples?

RSpec shared examples can be used to DRY up your code and make testing easier. After all, their purpose is to make test examples reusable. The most valuable shared examples are highly general and portable, meaning there isn’t much context required, and they can be used in many of your tests.

What is subject in RSpec?

Summary: RSpec’s subject is a special variable that refers to the object being tested. Expectations can be set on it implicitly, which supports one-line examples. It is clear to the reader in some idiomatic cases, but is otherwise hard to understand and should be avoided.

What is RSpec gem?

rspec is a meta-gem, which depends on the rspec-core, rspec-expectations and rspec-mocks gems. Each of these can be installed separately and loaded in isolation using require .
