Today, we are focusing on Selenium, a powerful tool for automating web browsers. Can anyone explain what Selenium is?
Isn't Selenium used to write automated tests for web applications?
Correct! Selenium allows us to write test scripts in various programming languages. What's great about it is that we can automate user interactions in web apps. Who can give an example of a simple action we might automate?
Logging in to a website could be one, right?
Exactly! Today we'll automating a login test, which is essential for verifying user conditions in web applications.
To help us remember, here’s a simple mnemonic: 'Selenium Simplifies Tests' — that's our goal today!

Now let's write a Selenium script. What do you think are the main components of our script for login validation?
We need to specify the web driver, the URL, and then the actions to perform.
Right! We'll start with the web driver instance. Can any of you remind me how we access the Chrome browser using Selenium?
We use `webdriver.Chrome()` to initiate the Chrome browser.
Great! Don’t forget to include the URL for the login page as well. Now, let’s think about the possible input cases: what should our script do for valid and invalid credentials?
For valid credentials, it should redirect to the dashboard. For invalid ones, it should display an error message.
Exactly! These scenarios are essential for ensuring our application functions correctly. Remember: 'Verify First, Then Trust'.
Executing and Reporting Test Results

Now that we've written our script, how do we execute it?
We just run the script using our IDE, right?
That's correct! And once we do that, how do we determine success? What should we look for in our results?
We need to compare the expected output with the actual output from the test.
Yes! This comparison is crucial for identifying any issues. If the test fails, what should we do next?
We should log the error and possibly write a report detailing what went wrong.
Excellent! Remember to take detailed notes. Let's summarize: Run, Compare, Log.

In this section, students engage in a mini project to automate the login test for a web application. They learn to write Selenium scripts that handle authentication with both valid and invalid credentials, enhancing their understanding of testing automation.
Detailed
Day 45: Mini Project – Automate Login Test
In this section of the course, students will undertake a mini project aimed at automating the login test for a sample web application. The key objectives are to familiarize students with writing Selenium scripts that simulate user interactions with the login interface of a web app. This practical exercise emphasizes the importance of both valid and invalid authentication attempts, reinforcing the concept of validating error handling and user experience in software testing.
Learning Objectives:
- Understanding Selenium Basics: Students will implement basic Selenium tests, recognizing how browser automation works.
- Crafting Automation Scripts: Focus will be on writing structured Selenium scripts, considering various test scenarios for the login feature.
- Running and Reporting: After executing the scripts, students will learn how to report results effectively, noting any discrepancies between expected and actual outputs.
Significance:
This mini project bridges theoretical knowledge of test automation with practical application, preparing students to handle real-world software testing challenges.

Chapter Content
Students automate a login test for a sample web app.
Detailed Explanation
In this mini project, students are tasked with automating the login process of a hypothetical web application. This project serves as a hands-on way to apply what they've learned in automation testing, particularly with Selenium. They must develop a script that tests the login functionality using various sets of credentials to ensure it works as intended.
Examples & Analogies
Consider this task like making a recipe: If you follow the recipe carefully – gathering ingredients, measuring quantities, and cooking them at the correct temperatures – you should end up with a delicious dish. Similarly, by carefully scripting your automation tests, you ensure your login feature works correctly, like a well-cooked meal that meets expectations.
Writing the Selenium Script

Chapter Content
- Write a Selenium script for login with valid/invalid credentials.
- Execute the script and report results.
Detailed Explanation
The first step is to write the Selenium script. This script will automate the steps a user takes to log in, such as entering a username and password and clicking the login button. It’s important to write tests for both valid credentials (to confirm successful logins) and invalid credentials (to check that appropriate error messages are shown). After the script is written, students will run the script to see how it performs and to capture the results of the tests.
Examples & Analogies
Imagine you're a student taking an exam. Before taking it, you might practice with sample questions (valid inputs) and test your knowledge on questions you find challenging (invalid inputs). Once you’ve practiced, you would review your answers to see how well you did. Similarly, executing the Selenium script helps you assess whether the login features function correctly under different circumstances.
Analyzing Results

Chapter Content
Execute the script and report results.
Detailed Explanation
After executing the Selenium script, students are required to analyze the results. This involves looking at whether the script successfully logged in with valid credentials and displayed appropriate error messages when invalid credentials were used. Students should document any discrepancies or bugs encountered during testing, which will help in further refining the application.
Examples & Analogies
Think of it as inspecting your work after completing a project. For instance, if you built a model airplane, you would check to ensure all pieces fit correctly and that it flies. If something goes wrong, you'd note what didn't work to fix it. Similarly, analyzing the Selenium test results helps ensure that the application’s login feature operates as expected, and whether adjustments are necessary.
