Cucumber hooks for setup and teardown
Cucumber hooks are blocks of code that run before or after a scenario. They provide a way to set up preconditions or perform cleanup tasks before and after each scenario. There are two types of hooks in Cucumber: Before hooks and After hooks.
Here's an example of using Before and After hooks in Cucumber:
Before do
# Perform setup tasks, such as creating a new instance of the test object
end
After do
# Perform cleanup tasks, such as closing the browser window
end
Feature: Login functionality
As a user, I want to be able to log into the system
so that I can access my account information.
Scenario: Successful login
Given the user is on the login page
When the user enters a valid username and password
Then the user should be taken to the home page
In this example, the Before hook runs before each scenario and sets up the test environment by creating a new instance of the test object. The After hook runs after each scenario and performs cleanup tasks, such as closing the browser window.
You can also specify hooks that run only before or after specific scenarios, features, or tags by passing a block with a tag or scenario argument to the hook method.
Here's an example of using a hook that runs only before a specific scenario:
Before('@login') do
# Perform setup tasks specific to the login scenario
end
Feature: Login functionality
As a user, I want to be able to log into the system
so that I can access my account information.
@login
Scenario: Successful login
Given the user is on the login page
When the user enters a valid username and password
Then the user should be taken to the home page
In this example, the hook will only run before the Successful login scenario, which is tagged with @login.
Hooks allow you to set up and clean up your test environment before and after each scenario, ensuring that each test starts and ends in a known state. This helps to make your tests more reliable and reduces the risk of unexpected behavior due to environmental factors.
