What Is Cucumber in Software Testing?<\/h2>\n\n\n\n
Cucumber is a BDD testing framework that allows test scenarios to be written in plain English using the Gherkin language. It enables collaboration between testers, developers, and business stakeholders by translating human-readable requirements into automated tests.<\/p>\n\n\n\n
Cucumber tests consist of:<\/p>\n\n\n\n
- \n
- Feature files written in Gherkin syntax<\/li>\n\n\n\n
- Step definition files written in programming languages like Java or Python<\/li>\n\n\n\n
- Hooks and annotations that control execution behavior<\/li>\n<\/ul>\n\n\n\n
Hooks and annotations are not optional utilities; they are core building blocks in real-world automation projects taught in structured QA tester classes<\/strong>.<\/p>\n\n\n\n
Cucumber Hooks:<\/strong><\/h2>\n\n\n\n
Cucumber hooks<\/strong> are blocks of code that runs before or after each scenario. It can be defined anywhere in project or step definition layers using methods @Before, @After. Cucumber hooks Annotations allow us to manage better code workflow and help in reducing code redundancy<\/a>. Cucumber hooks are used in a situations where prerequisite steps before testing any test scenario is performed. <\/p>\n\n\n\n
- \n
- @Before Hook<\/strong>: It will execute before every scenario. Example<\/li>\n<\/ol>\n\n\n\n
@Before\npublic void initialization() {\nstart Browser();\n}<\/pre>\n\n\n\n- \n
- @After Hook:<\/strong> It will execute after every scenario.<\/li>\n<\/ol>\n\n\n\n
@After\nPublic void afterScenario () {\n TakeScreenshot();\n CloseBrowser ();\n}<\/pre>\n\n\n\nHow to implement Cucumber hooks in Java?<\/strong><\/h2>\n\n\n\n
Testing Hooks with single scenario<\/p>\n\n\n\n
Feature File<\/strong><\/p>\n\n\n\n
Feature: Test Hooks<\/p>\n\n\n\n
Scenario: This scenario is to test hooks functionality<\/p>\n\n\n\n
Given this is the first step<\/p>\n\n\n\n
When this is the second step<\/p>\n\n\n\n
Then this is the third step<\/p>\n\n\n\n
Step Definition file<\/strong><\/p>\n\n\n\n
package stepDefinition;\n \nimport cucumber.api.java.en.Given;\nimport cucumber.api.java.en.Then;\nimport cucumber.api.java.en.When;\npublic class Hooks_Steps\n{\n @Given (\"^this is the first step$\")\n public void This_Is_The_First_Step(){\n System.out.println(\"This is the first step\");\n }\n \n@When (\"^this is the second step$\")\n public void This_Is_The_Second_Step(){\n System.out.println(\"This is the second step\");\n }\n \n@Then(\"^this is the third step$\")\n public void This_Is_The_Third_Step(){\n System.out.println(\"This is the third step\");\n } \n}\n<\/pre>\n\n\n\nHooks<\/strong><\/h4>\n\n\n\n
package utilities;\nimport cucumber.api.java.After;\nimport cucumber.api.java.Before;\npublic class Hooks \n{\n @Before\n public void beforeScenario(){\n System.out.println(\"This will run before the Scenario\");\n } \n \n @After\n public void afterScenario(){\n System.out.println(\"This will run after the Scenario\");\n }\n}\n<\/pre>\n\n\n\nIf the testcase fails in that case also After<\/strong> Hook will execute for sure. Package import statement should be import cucumber.api.java.After; & import cucumber.api.java.Before;<\/strong> Scenario Hooks execute before and after every scenario.<\/p>\n\n\n\n
What are<\/strong> Cucumber Annotations?<\/strong><\/h2>\n\n\n\n
- @After Hook:<\/strong> It will execute after every scenario.<\/li>\n<\/ol>\n\n\n\n
- @Before Hook<\/strong>: It will execute before every scenario. Example<\/li>\n<\/ol>\n\n\n\n
