Example
Creating a QA automation framework is quite an involved process that could span multiple files and directory structures. One common approach is using Selenium for web application testing along with a testing framework such as NUnit (given your .NET background).
Here’s a simplified example of how you might set up a Selenium test with NUnit to automate a basic login process for a web application:
- First, install the necessary packages using NuGet:
Selenium.WebDriver
Selenium.Support
NUnit
NUnit3TestAdapter
dotnet add package Selenium.WebDriver --version 3.141.0
dotnet add package Selenium.Support --version 3.141.0
dotnet add package NUnit --version 3.13.2
dotnet add package NUnit3TestAdapter --version 3.17.0Create a new file, LoginTests.cs, and populate it with the following code:
using System;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
namespace QA_Automation
{
[TestFixture]
public class LoginTests
{
private IWebDriver _driver;
[SetUp]
public void SetUp()
{
// Initialize the Chrome driver (ensure ChromeDriver is installed
and available in PATH)
_driver = new ChromeDriver();
}
[Test]
public void CorrectLogin()
{
// Navigate to the login page
_driver.Navigate().GoToUrl("https://example.com/login");
// Locate the username and password fields, and the submit button
var usernameField = _driver.FindElement(By.Name("username"));
var passwordField = _driver.FindElement(By.Name("password"));
var submitButton = _driver.FindElement(By.Name("submit"));
// Input the username and password, then click the submit button
usernameField.SendKeys("correct_username");
passwordField.SendKeys("correct_password");
submitButton.Click();
// Verify that login was successful by checking the URL
Assert.AreEqual("https://example.com/dashboard", _driver.Url);
}
[TearDown]
public void TearDown()
{
// Close the browser once the tests are done
_driver.Quit();
}
}
}
Explanation:
- The
SetUpmethod is executed before each test, initializing the Selenium WebDriver with the Chrome browser driver. - The
CorrectLogintest method navigates to a login page, locates the username and password input fields and the submit button on the page, inputs a correct username and password, clicks the submit button, and then checks the URL to verify that the login was successful. - The
TearDownmethod is executed after each test, closing the browser to clean up resources.
This is a simplistic example, but it demonstrates the basic structure of a Selenium test with NUnit.
In a real-world scenario, you would likely have additional setup steps, more comprehensive verification steps, and possibly some error handling.
