Compatibility Testing

Compatibility testing is about ensuring that the website functions as expected across different environments, platforms, devices, browsers, and operating systems. In a world with increasing diversity, the user experience becomes more and more personalized based on the device they used to browse your website, and so compatibility testing becomes a must-have.                    
 

Before performing compatibility testing or cross-browser testing, QA teams must identify the sources of their website user. To optimize resources, it is better to conduct testing on devices and environments that the majority of users are using to browse your website.

• Popular Browsers (Desktop - Mobile):
  • Google Chrome
  • Mozilla Firefox
  • Safari
  • Microsoft Edge
  • Opera
  • Brave
  • Samsung Internet (for Android)
     
• Popular Operating Systems (Desktop - Mobile):
  • Windows 10
  • macOS Big Sur
  • Linux (Ubuntu, Fedora, etc.)
  • iOS (iPhone, iPad)
  • Android
     
• Popular Device Types:
  • Desktop Computers
  • Laptops
  • Tablets (iPad, Android tablets)
  • Smartphones (iPhone, Android phones)
     
• What to Test on Different Devices:
  • Compatibility with different operating system versions (e.g., iOS 14, Android 11)

  • Verifying proper loading and performance across different network speeds
  • Checking how the application handles data transfer and network-related functionalities

Performance Testing

The end goal of performance testing is to identify performance bottlenecks of the website and ensure that it can deliver a decent user experience in case there is extreme traffic volume. Here is a QA checklist for performance testing on a website:

• Average response time for typical user actions
• Response time during peak user load
• Transaction throughput (number of transactions processed per second)
• Server CPU utilization under load
• Memory usage and allocation patterns
• Network latency and response time across different geographic regions
• Maximum concurrent user capacity before performance degradation
• Connection pool efficiency and performance impact on response time
• Page load time for different page types and sizes
• Database query performance and optimization opportunities
• Effectiveness of caching mechanisms in reducing response time
• Error rate and error handling under high load conditions

Usability Testing

Usability testing is a unique type of testing, requiring a lot of intuition and empathy. Before performing usability testing, the tester must select a representative sample of users that match the target audience of the website and understand what appeals to them from a UX standpoint. They can either rely on traffic analytics or use real-life feedback to gain insights into this user group, then manually browse the website to see if the website is optimized for this specific audience.                   
 

Here is a checklist of what to look for when defining your user group:

• Demographic characteristics (age, gender, location, occupation, education level)
• User behavior and goals (what they are looking to achieve on the website)
• Technical proficiency (level of familiarity and skill with using websites)
• Device and platform preferences (desktop, mobile, operating system)
• Accessibility needs (considering users with disabilities or specific accessibility requirements)
• Language preferences (if your website serves multiple languages)
• Content preferences (what type of content they are interested in or expect to find)
• Frequency of website usage (regular users vs. occasional visitors)
• Customer segmentation or target market analysis
• Feedback and input from stakeholders or existing users
• Consideration of any legal or compliance requirements (e.g., age restrictions)

After fully understand what the users want, testers can browse the website to check if it has been well-designed to serve the needs of that group:

• Navigation and menu usability
• Readability and legibility of content
• Clarity of instructions and guidance
• Ease of use for common tasks and actions
• Consistency in design and layout
• Accessibility for users with disabilities
• User feedback and error reporting mechanisms
• Visual appeal and aesthetics
• Intuitiveness of user interface and interactions

API Testing

API Testing is a more technical side of web testing, focusing on checking if APIs connecting your website with external systems and applications are working properly.

• Request validation (parameters, headers, payload)
• Response validation (status codes, headers, data)
• Error handling and error codes
• Authentication and authorization mechanisms
• Rate limiting and throttling
• Data validation and data integrity
• Testing different API methods (GET, POST, PUT, DELETE)
• Testing API endpoints and URL structures
• Handling of query parameters and filters
• Testing API caching and cache control headers
• Testing API security (e.g., SSL/TLS encryption)
• Testing concurrent API requests and concurrency limits
• Load and performance testing of APIs
• Testing API integration with third-party systems or services
• Testing API versioning and backward compatibility
• Webhook and event notification testing
• Handling of edge cases and boundary conditions
• API documentation accuracy and completeness

Visual Testing

Visual testing is crucial for ensuring that an application or website's user interface (UI) meets design and usability standards. Visual defects or inconsistencies can affect the user experience, leading to frustration, decreased productivity, or abandonment of the application. Traditional functional testing methods may miss visual issues like misaligned elements, broken images, or incorrect fonts or colors, so we must also have visual testing to ensure comprehensive testing:

• Layout and alignment of elements on different screen sizes
• Font styles, sizes, and readability
• Color scheme and contrast for text and backgrounds
• Images and graphics display and quality
• Logo visibility and consistency
• Navigation menu appearance and functionality
• Buttons and interactive elements design and behavior
• Consistency in styling across different pages
• Use of whitespace and padding for visual clarity
• Responsive design and mobile-friendly layout
• Consistent branding elements (colors, logos, fonts)
• Header and footer display and consistency
• Text formatting (paragraphs, headings, lists)
• Usage of icons and symbols for clarity and usability
• Error messages and validation notifications visibility
• Form field design and input validation
• Loading indicators and progress bars appearance
• Visual feedback for user interactions (hover, click, etc.)
• Compatibility with different web browsers
• Consistency in visual elements across different devices

Accessibility Testing

The final aspect of web testing is accessibility testing - a practice to ensure that the website is friendly for disabled users who find it hard to browse the website without assistive technologies (i.e. screen readers, voice recognition, color blindness support, etc.)

• Keyboard accessibility for navigating and interacting with the website
• Proper use of ARIA (Accessible Rich Internet Applications) attributes
• Alternative text for images and multimedia content
• Proper heading structure and hierarchical organization
• Color contrast for text and background elements
• Logical and descriptive link text
• Form fields with appropriate labels and accessible input instructions
• Consistent and meaningful use of focus indicators
• Video and audio captions or transcripts for multimedia content
• Text resizing and scalable layout for users with low vision
• Skip navigation links to bypass repetitive content
• Clear and understandable error messages and validation prompts
• Consistent and intuitive navigation menus and site structure
• Accessible forms with error validation and clear instructions
• Support for assistive technologies like screen readers and screen magnifiers
• Proper use of headings, lists, and other formatting elements
