Using Gherkin can actually help in testing as it serves as a good document for all the features and can be written by anyone even with almost zero coding knowledge for more selenium training.Clients say, “Cucumber benefits us to understand the application code as it uses Gherkin language which is in Plain Text.”Being written in Gherkin, it acts as a bridge between various layers, PMs — Dev — Testers — Clients.
This helps team members even with no technical know-how to understand what is going on in the project that closes the gap between business people and technical peopleIn addition to low technicality and easier to understand approach, main advantage of BDD is that it transpires from TDD ie.
Test Driven Development, which supports automated testing with multiple test data with minimum intervention in code.Cucumber — A BDD Framework Tool: BDD is implemented with the help of Cucumber framework which helps in automating the cases in a well formatted and readable form.Cucumber feature files: These files written in Gherkin language ending with .feature extension are an integral part of Cucumber and are used for application specifications.Getting Started With Gherkin For Selenium TestingNow that you know what BDD is let’s get started with Gherkin for Selenium Testing.Gherkin is a Business Readable, Domain Specific Language which entitles its users to write effectivetests in a well documented way that requires least reasoning and involved logic details.Let us understand this with a Gherkin example.“Buyers should not be able to fill invalid credit card details.”Versus“On the payment page, If a buyer enters a credit card number, that is not 16 digits of length, then when they try to proceed, it should give an error message pop up stating that the entered number is not correct.”The first Gherkin example is unclear and vague in comparison to the second one.
Vagueness leads to errors and makes it harder for the tester to understand the requirement and implement test cases.Gherkin Syntax For Selenium TestingFile structure in Gherkin is defined by the way different lines of code are indented in a feature file.
Almost all lines in Gherkin for Selenium Testing starts with a special keyword and line endings terminate statements which are called as steps.A Gherkin feature file is a combination of features, scenarios and steps which generally looks like this selenium online training:Feature: Some terse yet descriptive text of what is desiredBackground:Some common prerequisite setup applicable to all situationsScenario: Some determinable business situationGiven some preconditionAnd some other preconditionWhen some action by the actorAnd some other actionAnd yet another actionThen some testable outcome is achievedAnd something else we can check happens tooScenario: A different situationWhen executing the feature, the trailing portion of each step (after keywords like Given, And, When, etc) is matched to a regular expression generally called as glue code and can be written in any language.
It is like an untitled optional scenarioBackground : Given a customer named JohnWhen clicks on buy now buttonThen he should be redirected to payment pageScenarioScenario makes the core of Gherkin structure.
