Blog # 5 : 🎭 Understanding the Playwright Configuration File 🎭

🚀As I dive deeper into Playwright for end-to-end testing, I encountered the automatically generated Playwright configuration file. At first glance, it looked complex, filled with various options and settings that I didn’t fully understand. However, as I progressed in my learning, I started grasping its significance and how it can be customized to suit my testing needs.🎯

📜My Playwright Configuration File

As a beginner, I’ve modified the default Playwright configuration file to better suit my needs. Here’s what I’m currently using:

This configuration keeps things simple while enabling useful debugging features like screenshots, video recordings, and traces when failures occur.

🔍 Breaking Down the Configuration

To make sense of this file, let's go through the key options and their roles:

📂 Test Directory and Execution Settings

testDir: './tests' 📁: Defines the folder where Playwright looks for test files.
timeout: 30000 ⏳: Sets a maximum test execution time of 30 seconds.
expect: { timeout: 10000 } ⚡: Ensures assertions fail if they take longer than 10 seconds.

📊 Test Reporting and Debugging

reporter: 'html' 📜: Generates an easy-to-read HTML report for test results.
screenshot: 'only-on-failure' 📷: Captures a screenshot only when a test fails, helping with debugging.
video: 'retain-on-failure' 🎥: Saves a video of the test execution but only if the test fails.
trace: 'on-first-retry' 🕵️: Records a trace file when a test fails on its first retry, allowing detailed analysis of what went wrong.

🌍 Browser Configuration

browserName: 'chromium' 🌐: Specifies that tests will run in Chromium by default.
headless: false 👀: Runs tests in a visible browser window instead of headless mode, useful for debugging.

Key Takeaways

✅ The Playwright configuration file controls test execution, reporting, and debugging features.

✅ Screenshots, video recording, and tracing help debug test failures efficiently.

✅ Running tests in non-headless mode (headless: false) is helpful for visual debugging.

✅ Keeping configurations simple in the beginning allows a smoother learning experience.

🎯 Conclusion

The Playwright configuration file may seem overwhelming initially, but breaking it down into key sections makes it more manageable. By understanding the most relevant settings first, I can set up a solid testing workflow without getting lost in unnecessary details.

This is just the start of my Playwright journey, and I'm excited to learn more! 🚀 If you're also a beginner, I hope this breakdown helps you get a better grasp of Playwright’s configuration.

Happy testing! 🧪🎉

Software Testing Heuristics and mnemonics.

Software Testing Heuristics Heuristics are simply experience-based techniques for problem-solving, learning, and discovery. Where an exhaustive search is impractical, heuristic methods are used to speed up the process of finding a satisfactory solution. Examples of this method include using a rule of thumb, an educated guess, an intuitive judgment, or common sense. When you face a problem, you try some solutions that may work. For instance, if you suddenly find your mobile hang, what do you do? You may restart your mobile first. If that doesn’t work, then you may check & update the latest software and uninstall suspicious apps.if that also doesn’t work, then you reset your phone setting ( Factory reset). Most of us try a number of steps to solve our problems. These steps may not always work but we try them because we know that they may work. Following heuristics can apply to absolutely any kind of system with any kind of interface. 1.Abstract Remove details in a model. S...

Blog # 9: Say Hello to Alerts! Handling Dialog Boxes in Playwright

Alerts and dialogs are common elements in web applications that can interrupt automated test flows if not handled properly. Playwright provides straightforward methods to manage these interruptions, ensuring your tests run smoothly. In this guide, I’ll share how I learned handling three types of dialogs—simple alerts, confirmation boxes, and prompts—using Playwright’s built-in features. Why Handle Dialogs? Dialogs often appear during critical user interactions, such as form submissions, error notifications, or data input requests. If ignored, they can cause tests to freeze or fail. Playwright’s dialog-handling capabilities allow you to: Validate dialog messages. Accept, dismiss, or respond to prompts programmatically. Keep tests resilient and predictable. Let’s explore how to tackle each type of dialog. 1. Simple Alerts: The One-Way Notification A simple alert is a basic pop-up with an "OK" button. Example Scenario : A basic alert appears, shouting, "I am an alert box!...

Blog # 4 : A Deep Dive into Playwright Assertions

Ever spent hours debugging a test only to realize you forgot to check if a button was actually clickable? In web testing, the devil's in the details—and that's where assertions become your best friend. Let's explore how Playwright's assertion library can transform your testing strategy, using the popular The Internet testing playground. Why Assertions Matter Assertions are the backbone of any meaningful test. They're the checkpoints that scream, "This works!" or "Something's broken here!" Playwright's built-in expect library shines when testing real-world scenarios like authentication flows and dynamic content. Let's Start Testing: A Real-World Scenario We'll be testing key features of The Internet playground. Here's our foundation: Now let's add powerful assertions. Validating Content: Is What You See What You Get? 1. Page Titles: Your First Line of Defense Verify you're on the correct page immediately after na...

What is Agile?

Recently I did a presentation after almost 20 years at a Bootcamp showcase on Agile. As Agile celebrated its 20th anniversary this year I decided to talk on what Agile is? Below are the few drops from Agile's ocean which I managed to pour during my showcase. What is Agile Software Development? Agile is a time boxed, iterative approach to software delivery that builds software incrementally from the start of the project, instead of trying to deliver it all at once near the end. It works by breaking projects down into little bits of user functionality called user stories, prioritizing them, and then continuously delivering them in short time cycles called iterations. In iterative development, feature code is designed, developed and tested in repeated cycles. With each iteration, additional features can...

Blog # 20 :🎪 Playwright Hooks: Your Test Suite’s Best Friends!

🎩 Why Hooks? The Magic Behind the Scenes When writing automated tests, especially for web applications, repetitive tasks like logging in before each test or cleaning up after the test run can quickly clutter your code. If you've found yourself copying the same setup code into multiple tests, you're not alone! Luckily, Playwright offers a powerful feature to solve this — hooks . Imagine you’re hosting a party 🥳. You wouldn’t clean the house after every guest leaves, right? Instead, you’d: 🏗️ Setup once (decorate, cook food) → beforeAll 🗑️ Clean as you go (refill snacks, wipe spills) → beforeEach/afterEach 💣Nuclear cleanup after everyone leaves → afterAll In testing terms: Hooks automate repetitive tasks so your tests can focus on what matters. 🔮 Meet the 4 Hooks 🚀 Your Code in Action: Login/Logout Flow Let’s automate a shopping site test (your code!). Step 1: beforeEach – The “Welcome Mat” Why it rocks: Every test starts fresh, logged in, and cookie-free! test. beforeEa...

What is Quality

✨ What is Quality? Quality means different things to different people. For some, the brand Apple 🍏 is synonymous with quality. For others, it’s difficult to define quality, but surprisingly easy to recognize based on their experiences. A quality product or service is one that satisfies customer needs and meets (or even exceeds!) their expectations. When you receive quality, in whatever form, you're eager to get more. You want to return for another purchase, refer the product to friends, and talk about it publicly. Quality is what we should aim for to ensure returning customers and a strong brand as a company. According to IEEE , quality is defined as “The degree to which a component, system, or process meets specified requirements and/or user/customer needs and expectations.” 📈 👥 Who is Responsible for Software Quality? Everyone involved in a software project—including the Product Owner , Scrum Master , Developer , Tester , and other stakeholders such as the Business ...
