SpecFlow Tutorial for Automation Testing

Organisations have been leveling up constantly to maintain the quality of the ware they deliver, which proceed through the SDLC. The utmost priority while testing is that users get a bug-free product. However, what if in achieving a mutual goal, there is entirely no communication gap among the project contributors?

That would help in apply various ideas, leading towards a better-tested product. These contributors could be examiner, developers, QAs, etc. Well, to achieve such a dream, engineering has advanced so much to introduce (Behaviour Driven Development) into the conversation.

This guide will deep dive into the internalization of BDD attack while writing exam using SpecFlow automatise testing.

What is BDD testing?

To understand BDD, let ’ s first go through TDD. is not any technology, nonetheless, it is a technique in which developers pen codification only when the test neglect. On the like note, BDD is an drawn-out variant of TDD, in which the mind behind the implementation is to focus on the behavior of the projection rather than testing.

• It is a scheme to build conversations among different teams of the project to unify towards identifying users ’ stories.
• The approach of this technique is to use language that could be easily silent even by a non-technical personality.
• This gives an vantage of getting their contributions, which could aid accomplish best testing behavior.
• BDD apply the Gherkin speech, which helps determine test scenario without proficient cognition.

Edges of BDD Testing

• BDD ensures that every contributor remains on the same page, and execute not face any technical challenges while contributing to write test scenarios.
• You don ’ t need to have coding noesis while writing tryout using the BDD attack, all the tests are written in mere English language.
• Anyone could maintain tests, without being an expert in.

What is SpecFlow?

SpecFlowis an open-source mechanization testing framework for .NET coating that can incorporate BDD approaches while. Apart from .NET applications, which are the applications that are created with the help of C # (C sharp) programming language, it indorse Xamarin and Mono, which are the frameworks of .NET application.

SpecFlow increase the amount of efficient collaboration, by using the BDD approach, and hence it reduces the time of development.

SUSA automates exploratory testing with persona-driven behavior, catching bugs that scripted automation misses.

How to Write SpecFlow tryout using BDD?

In the BDD technique, tests are compose in the Gherkin language. In SpecFlow automate examine, you will use Gherkin lyric with predefined keywords such as scenario, given, when, so, and, but, etc. For example,

Scenario: Click on the SpecFlow tutorial link Given I am on the Browserstack site When I click the SpecFlow with selenium c # blog Then I should see the SpecFlow tutorial page

• Scenario: Every test representative get with a scenario keyword, which contains one or more steps to postdate further. It is optional to put a scenario rubric.

• Given: This states the pre-required condition for the scenario. In the above example, Given states a requirement, that you have to be on the BrowserStack website.

• When: It states the activity required to be fulfill in the scenario.

• Then: It states the outcome of the scenario. In the above example, reaching the SpecFlow tutorial page get the outcome, the terminus of the scenario, which is quoted inThen.

What are Bindings?

The use of Gherkin language in BDD is but to ensure collaboration, however, we ’ re perpetually using some steganography language behind the scenes, therefore, the automation that connects the Gherkin specification to a germ code is known as binding.

To implement, we have to use the [Binding] attribute before publish the footstep definition.

Implementation of SpecFlow

Prerequisites:

• IDE: Download and install any IDE of your option. In this tutorial, we are habituateMicrosoft Visual Studio 2022. (Note & # 8211; Ocular Studio and Visual Studio code are different)
• SpecFlow: SpecFlow is installed as an extension in the IDE of your choice.
• .NET framework:Install the latest variant of the .NET Framework on your machine.
• Selenium: You must have a introductory savvy of and must besides install Selenium on your system. In this SpecFlow tutorial, Selenium will assist in automatize our SpecFlow tests.
• Browser Webdriver:Install any browser Webdriver depending upon the browser you want to run your trial.

Step 1: Installing SpecFlow and required dependency

• To install SpecFlow, go to handle extensions and establish the propagation“ SpecFlow for Visual Studio 2022”. After instal, re-start your Visual Studio and create a new projection use the SpecFlow template.

• Now, download a few parcel that will serve as dependencies of your project. Navigate toTools - & gt; NuGet Package Manager - & gt; Manage NuGet bundle for solution. Here you feature to install a few more packages:

1. SpecFlow.NUnit
2. SpecFlow.Tools.MsBuild.Generation
3. NUnit test adaptor
4. Selenium.Webdriver
5. Selenium Webdriver.ChromeDriver

Search for each package and install them one by one.

Step 2: Folder structure of our task

We are going to make a examination, where a login will be happen on thebstackdemosite. Also, we are going to use to maintain our tests. This will remain the file structure for our project.

Step 3: Writing Code

• We will start by creating the most interesting constituent, lend scenarios in the lineament file, using the Gherkin language. Add the following script inside the lineament file.

Feature: Signin @ smoke Scenario: Signin to bstackdemo website Given I open bstackdemo homepage And I click signin tie-in And I enter the login item And I click login button Then Profile Name should appear

• Now, let ’ s make thePage.csfile. Here you must be aware of Selenium. Add the following code inside thePage.csfile. We are creating this file to implement the Page object model using Selenium.

using OpenQA.Selenium; namespace SpecFlowTutorial.Pages {public form Page {public IWebDriver webDriver {get;} public Page (IWebDriver webDriver) {WebDriver = webDriver;} public IWebElement SignInLink = & gt; WebDriver.FindElement (By.LinkText (`` Sign In '')); public IWebElement UsernameSpace = & gt; WebDriver.FindElement (By.Id (`` username '')); public IWebElement UsernameOption = & gt; WebDriver.FindElement (By.XPath (`` // * [@ id='username '] /div [2] '')); public IWebElement PasswordSpace = & gt; WebDriver.FindElement (By.Id (`` watchword '')); public IWebElement PasswordOption = & gt; WebDriver.FindElement (By.XPath (`` // * [@ id='password '] /div [2] '')); public IWebElement LoginButton = & gt; WebDriver.FindElement (By.Id (`` login-btn '')); public IWebElement ProfileName = & gt; WebDriver.FindElement (By.LinkText (`` demouser '')); public IWebDriver WebDriver {get;} public void ClickSignIn () = & gt; SignInLink.Click (); public void ClickLoginButton () = & gt; LoginButton.Submit (); public bool isProfileNameExist () = & gt; ProfileName.Displayed;}}

• Once the step get be created, we will now create footstep definitions of the steps. Right-click on any step, then select generate step definition. This will create a new file for compose footstep definitions with some boilerplate code. Here supersede the default script with the required code.

using NUnit.Framework; using OpenQA.Selenium; using OpenQA.Selenium.Chrome; using SpecFlowTutorial.Pages; using TechTalk.SpecFlow; using TechTalk.SpecFlow.Assist; namespace SpecFlowTutorial.StepDefinitions {[Binding] public seal class Steps {Page Page; [Given (@ '' I open bstackdemo homepage '')] public void GivenIOpenBstackdemoHomepage () {IWebDriver webDriver = new ChromeDriver (); webDriver.Navigate () .GoToUrl (`` https: //bstackdemo.com/ ''); Page = new Page (webDriver);} [Given (@ '' I click signin link '')] public void GivenIClickSignInLink () {Page.ClickSignIn ();} [Given (@ '' I enter the login details '')] public void GivenIEnterTheLoginDetails () {Page.UsernameSpace.Click (); Page.UsernameOption.Click (); Page.PasswordSpace.Click (); Page.PasswordOption.Click ();} [Given (@ '' I tick login push '')] public void GivenIClickLoginButton () {Page.ClickLoginButton ();} [Then (@ '' Profile name should seem '')] public void ThenProfileNameShouldAppear () {Assert.That (Page.isProfileNameExist (), Is.True);}}}

Step 4: Executing our test

Navigate toTest - & gt; Run All Tests.

This will launch the exam adventurer in Ocular Studio and will perform our required test.

Summing it up

SpecFlow is an open-source testing framework for .NET applications. You can generate BDD tests using SpecFlow and automate them using Selenium at the like clip.

• The use of the Gherkin language bridges the gap among the QA, BA, Developer, and stakeholders.
• It offers freedom to exploiter to create characteristic files without having any technical knowledge, thereafter, a tester attach the Gherkin lyric to its necessary root codification.

In this SpecFlow automate testing tutorial, we used the Selenium server on our local system and ran a test on the Google Chrome browser, however, if you require to broaden your examination, you must use the Selenium grid to run cross-browser tests habituate. It ’ s seamless for running tests on multiple operating scheme and browsers simultaneously.

More than that, you can test in existent user conditions with network simulation and geolocation essay for uncompromising character.
