Exploratory testing is a manual way of testing software. Testers explore a system without a pre-made test plan or prior experience. They use their knowledge, skills, and creativity to find defects, vulnerabilities, and usability issues. This testing process combines learning, designing tests, and executing simultaneously. Exploratory testing is an agile method that allows testers to debug the code without a script.

Testers can thoroughly explore user flows using Web browser online tools from the web browser. You can identify potential problems and ensure a consistent user experience. This blog gives the best practices for using web browser online tools in exploratory testing and practical tips to enhance testing efficiency and effectiveness.

Utilizing Web Browser Online DevTools for Enhanced Testing

Here is how you can use online browser DevTools for advanced exploratory testing:

Inspecting and Modifying HTML/CSS

Browser DevTools are invaluable for inspecting and modifying HTML and CSS. They provide detailed insights into the structure and styling of web pages.

  • Element Inspection: DevTools allow testers to inspect individual HTML elements. This helps in understanding the DOM structure and locating elements quickly.
  • Live Editing: Testers can modify HTML and CSS directly within the browser. Changes are reflected immediately, aiding in visualizing the impact without altering the source code.
  • CSS Analysis: DevTools provides comprehensive information on applied CSS rules. Testers can see which rules are active and overridden, helping debug styling issues.
  • Layout Inspection: Tools like the box model viewer help testers understand element sizing and spacing. This is crucial for diagnosing layout problems and ensuring design consistency.
  • Performance Insight: You can examine the rendered markup and identify potential performance bottlenecks. This helps optimize load times and improve the user experience.

Monitoring Network Activity

Monitoring network activity is a key feature of Browser DevTools. It helps testers analyze how a web page interacts with the server.

  • Request Inspection: DevTools display all network requests made by the page. This includes details like request headers, response headers, and status codes.
  • Performance Metrics: Testers can see the time taken for each request. This helps identify slow-loading resources and optimize performance.
  • Resource Analysis: DevTools categorize network requests by type, such as scripts, images, and stylesheets. This aids in understanding resource utilization and load order.
  • Error Detection: The network panel highlights failed requests. Testers can investigate these to diagnose connectivity issues or server-side errors.
