30-Day Selenium Automation Testing Course

Dual-Track: C# (NUnit) + Python (PyTest)

Master Selenium WebDriver from scratch in 30 days. Every lesson includes complete code examples in both C# and Python, so you can follow whichever track fits your background -- or learn both side by side.

---

Prerequisites

Before starting this course, you should have:

• General: Basic understanding of HTML, CSS, and how web pages work (DOM structure, forms, links)
• For C# Track: Visual Studio 2019+ or VS Code with C# extension, .NET 6+ SDK installed, basic C# syntax knowledge (variables, loops, classes, methods)
• For Python Track: Python 3.8+ installed, a code editor (VS Code, PyCharm), basic Python syntax knowledge (variables, loops, functions, classes)
• Browser: Google Chrome (latest) or Mozilla Firefox (latest) installed
• OS: Windows 10/11, macOS, or Linux

No prior Selenium or test automation experience is required.

How to Use This Course

1. Pick your track -- C# (NUnit) or Python (PyTest) -- or follow both.
2. Complete one day per day. Each lesson is designed to take 1-2 hours including practice exercises.
3. Type the code yourself. Do not copy-paste. Muscle memory matters for automation.
4. Run every example against the practice websites listed below.
5. Use the Cheat Sheets as quick-lookup references while coding.
6. Build the Final Project in Week 4 to tie everything together.

Setup Instructions

C# Track (NUnit)

1. Install .NET SDK (6.0 or later) from https://dotnet.microsoft.com/download.

2. Create a test project:

   dotnet new nunit -n SeleniumCourse
   cd SeleniumCourse

3. Add Selenium packages:

   dotnet add package Selenium.WebDriver
   dotnet add package Selenium.Support
   dotnet add package WebDriverManager

4. Verify -- create a simple test that opens a browser:

   using NUnit.Framework;
   using OpenQA.Selenium;
   using OpenQA.Selenium.Chrome;
   using WebDriverManager;
   using WebDriverManager.DriverConfigs.Impl;
   
   [TestFixture]
   public class SetupCheck
   {
       private IWebDriver driver;
   
       [SetUp]
       public void Setup()
       {
           new DriverManager().SetUpDriver(new ChromeConfig());
           driver = new ChromeDriver();
       }
   
       [Test]
       public void BrowserOpens()
       {
           driver.Navigate().GoToUrl("https://www.google.com");
           Assert.That(driver.Title, Does.Contain("Google"));
       }
   
       [TearDown]
       public void Teardown()
       {
           driver.Quit();
       }
   }

5. Run: dotnet test

Python Track (PyTest)

1. Install Python 3.8+ from https://www.python.org/downloads/.

2. Create a virtual environment:

   python -m venv venv
   source venv/bin/activate   # Linux/macOS
   venv\Scripts\activate      # Windows

3. Install packages:

   pip install selenium pytest webdriver-manager

4. Verify -- create test_setup.py:

   import pytest
   from selenium import webdriver
   from selenium.webdriver.chrome.service import Service
   from webdriver_manager.chrome import ChromeDriverManager
   
   @pytest.fixture
   def driver():
       service = Service(ChromeDriverManager().install())
       drv = webdriver.Chrome(service=service)
       yield drv
       drv.quit()
   
   def test_browser_opens(driver):
       driver.get("https://www.google.com")
       assert "Google" in driver.title

5. Run: pytest test_setup.py -v
