What are different Hooks in Cucumber?
More often we use two types of hooks: “Before” hook and “After” hook. Method/function/piece of code, defined within Before and After hooks, always run, even if the scenario gets passed or failed.
What are Hooks in Cucumber framework?

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.

Why background is use in Cucumber?
Background in Cucumber is used to define a step or series of steps that are common to all the tests in the feature file. It allows you to add some context to the scenarios for a feature where it is defined.
What is the difference between background and scenario?
Background allows you to add some context to the scenarios in a single feature. A Background is much like a scenario containing a number of steps. The difference is when it is run. The background is run before each of your scenarios but after any of your Before Hooks.
What is difference between scenario and scenario outline in Cucumber?
Scenario and Scenario Outline serve different purposes, they are written the same way but Scenario Outline takes user data in the form of Example table and run the scenario. So rather than duplicating same scenario with different data, one can write one Scenario Outline and write all data in Example table.
