A Feature File is an entry point to the Cucumber tests. This is a file where you will describe your tests in Descriptive language (Like English). It is an essential part of Cucumber, as it serves as an automation test script as well as live documents.
What is meant by feature file?
A feature file is usually a common file which stores feature, scenarios, and feature description to be tested. The feature file is an entry point, to write the cucumber tests and used as a live document at the time of testing.
What is feature file in BDD?
Gherkin is the domain specific language used in BDD for writing software requirements in the form of feature files. Feature files are written in the Given-When-Then [GWT] format. Feature files usually consist of Feature Title, Narrative, Background, Scenarios, Steps, Tags, Example Tables and Doc Strings. Features.
What is feature file and step definition in Cucumber?
Steps definition file stores the mapping between each step of the scenario defined in the feature file with a code of function to be executed. So, now when Cucumber executes a step of the scenario mentioned in the feature file, it scans the step definition file and figures out which function is to be called.
What is feature and scenario in Cucumber?
Feature: A feature would describe the current test script which has to be executed. Scenario: Scenario describes the steps and expected outcome for a particular test case. Scenario Outline: Same scenario can be executed for multiple sets of data using scenario outline.
Who writes BDD scenarios?
Test engineers are typically responsible for writing scenarios while developers are responsible for writing step definitions. However, this doesn’t mean that they should be responsible for writing these things in isolation following a discovery meeting — the best approach is a collaborative one.
What is hooks in Cucumber?
Hooks. Hooks are blocks of code that can run at various points in the Cucumber execution cycle. They are typically used for setup and teardown of the environment before and after each scenario. Where a hook is defined has no impact on what scenarios or steps it is run for.
How many scenarios are in a feature file?
Answer: A feature file can contain a maximum of 10 scenarios, but the number can vary from project to project and from one organization to another. But it is generally advisable to limit the number of scenarios included in the feature file. Q #13) What is the use of Background keyword in Cucumber?
Can we run multiple feature files in Cucumber?
Cucumber can be executed in parallel using TestNG and Maven test execution plugins by setting the dataprovider parallel option to true. In TestNG the scenarios and rows in a scenario outline are executed in multiple threads. One can use either Maven Surefire or Failsafe plugin for executing the runners.
What is Gherkin language in Cucumber?
The language, in which this executable feature files is written, is known as Gherkin. Gherkin is a plain English text language, which helps the tool – Cucumber to interpret and execute the test scripts.
What is runner file in Cucumber?
Rest AssuredDynamic ProgrammingProgramming. We can run tests using a test runner file for Cucumber. The test runner file should contain the path of the feature file and step definition file that we want to execute. Code Implementation of the Feature file. Feature − Login Module.
What is a feature in Gherkin?
The Gherkin language has Feature and Scenario sections. In this sense, a Feature is simply a collection of related Scenarios. They align roughly to the more general meanings of the terms. Don’t over-think features with Agile, either. Some teams define a feature as a collection of user stories.
How do you write a Cucumber feature file?

How do you create a feature file?
Create a new feature file
- In the Project tool window, right click the features folder and select New | File.
- Name the new file. You can give it any name, but make sure to use the . feature extension (for example, BeerCans. feature ).
- After that, you can add the code for the feature file and create your test scenario.
What is the difference between hooks and background in Cucumber?
After hooks will be run after the last step of each scenario, even when there are failing, undefined, pending or skipped steps. Background is used to set up a precondition. A Background is run before each scenario, but after any Before hooks. In a feature file, we should add the Background before the first Scenario.
What is BDD syntax?
Behaviour Driven Development (BDD) is way of writing acceptance criteria by giving examples of how software should behave in different scenarios. They are written in a standard format that promotes clarity, as well as allowing easy integration with automated testing.
What is test cases in BDD?
Test scenarios in BDD are based on the concept of “given, when, then” to describe various user BDD scenarios. Test cases written so, in simple text, help even non-technical team members to understand what is going on in the software project, with or without a test management tool.
What is BDD testing example?
BDD Testing Example: Ubiquitous Language and AT Scenarios
To borrow from Vincent’s post, “The idea with acceptance testing is to write tests (or behavioral specifications) that describe the behavior of your software in a language which is not code but is more precise than standard English.”
What is data table in Cucumber?
What is the Data Table in Cucumber? Data tables are used when we need to test numerous input parameters of a web application. For example, the registration form of the new user involves several parameters to test, so for this, we can use the data table.
How data is passed in Cucumber?
When we have multiple test data to pass in a single step of a feature file, one way is to pass multiple parameters and another way is to use Data Tables. Data Tables is a data structure provided by cucumber. It helps you to get data from feature files to Step Definitions.
How many hooks are used in Cucumber?
two hooks
Unlike TestNG Annotations, cucumber supports only two hooks (Before & After) which works at the start and the end of the test scenario.
