Hooks

Hooks in Cucumber are like special methods that allow you to perform actions at specific points in your test execution lifecycle

Imagine hooks as special helpers in your Cucumber tests. They are pieces of code that run at specific points in the testing process, like before or after each scenario. They are also used to set up the environment before tests run or perform cleanup tasks after tests finish executing. Following are some of the common Uses for Hooks:

Setting up test data before scenarios run.
Starting or stopping services or servers.
Opening or closing connections (like databases or browsers).
Logging or reporting before or after tests.

Types of hooks in Cucumber:

@Before: This hook runs before each scenario. It's often used for setup tasks like initializing objects, connecting to databases, or logging in to applications.
@After: This hook runs after each scenario, regardless of whether it passed or failed. It's commonly used for cleanup tasks like closing connections, logging out of applications, or taking screenshots after failed tests.

Java

Copy

import io.cucumber.java.Before;
import io.cucumber.java.After;

public class Hooks {

    @Before
    public void beforeScenario() {
        System.out.println("Setting up the test environment...");
        // Perform setup tasks here, like launching browser or connecting to database
    }

    @After
    public void afterScenario() {
        System.out.println("Cleaning up the test environment...");
        // Perform cleanup tasks here, like closing browser or disconnecting from database
    }
}

Hooks execute in a specified order (e.g., Before hooks run before scenarios, After hooks run after scenarios). You can define hooks in separate classes or within your step definition files.
