The basic requirement of automated testing is to use same test again and again but with different set of data. Cucumber hook allows us to better manage the code workflow and helps us to reduce the code redundancy. If you have a hook you only want to run once before all the scenarios, use a global variable. In such cases, we can combine them in hooks. Cucumber Hooks allows us to better manage the code workflow and helps us to reduce the code redundancy. Cucumber hooks can come in handy when we want to perform specific actions for every scenario or step, but without having these actions explicitly in the Gherkin code.

Sometimes there could be common pre or post steps. Before the first step of each scenario, Before hooks will be run. 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.
