What is Security Testing?

Security testing identifies vulnerabilities in your application that could be exploited by attackers. It systematically evaluates defenses against unauthorized access, data breaches, and other threats to protect sensitive information and maintain user trust.

Types:

• Penetration Testing: Simulating hacker attacks to find weaknesses
• Vulnerability Scanning: Automated scanning for known security flaws
• Authentication Testing: Validating login and access control systems
• Authorization Testing: Checking user permission levels
• Encryption Testing: Verifying data protection during transmission/storage

What is API Testing?

API testing validates the reliability, performance, and security of Application Programming Interfaces the connectors that enable different software systems to communicate and exchange data seamlessly.

Types:

• Functional API Testing: Testing API endpoints for correct behavior
• Performance API Testing: Measuring response times under load
• Security API Testing: Checking for vulnerabilities in API access
• Contract Testing: Ensuring APIs meet documented specifications
• Integration API Testing: Verifying data flow between connected systems

What is Performance Testing?

Performance testing measures how your application behaves under various load conditions, assessing speed, stability, and scalability to ensure it meets user expectations during peak usage.

Types:

• Load Testing: Testing under expected normal user loads
• Stress Testing: Pushing beyond normal capacity to find breaking points
• Spike Testing: Testing sudden, extreme increases in traffic
• Endurance Testing: Running tests over extended periods
• Scalability Testing: Measuring performance as resources increase

What is Usability Testing?

Usability testing evaluates how easily and intuitively users can navigate and interact with your application, identifying design flaws and improving the overall user experience.

Types:

• Exploratory Testing: Observing users navigating freely
• Comparative Testing: Comparing against competitor interfaces
• First Click Testing: Analyzing initial user navigation choices
• A/B Testing: Comparing two interface versions with real users
• Accessibility Testing: Ensuring usability for people with disabilities

What is Compatibility Testing?

Compatibility testing verifies that your application functions correctly across different browsers, devices, operating systems, and screen resolutions, ensuring consistent user experience.

Types:

• Cross-Browser Testing: Testing on different web browsers
• Cross-Device Testing: Testing on mobile, tablet, and desktop
• Cross-Platform Testing: Testing on different operating systems
• Network Compatibility: Testing under various network conditions
• Backward Compatibility: Testing with older system versions

What is Regression Testing?

Regression testing confirms that new updates, features, or bug fixes don’t negatively impact existing functionality, maintaining system stability throughout development cycles.

Types:

• Unit Regression: Re-testing individual components after changes
• Partial Regression: Testing affected modules and dependencies
• Complete Regression: Re-testing the entire application
• Automated Regression: Using scripts to repeatedly test key functions

Visual Regression: Detecting unintended UI/visual changes

What is Accessibility Testing?

Accessibility testing ensures your application is usable by people with disabilities, complying with standards like WCAG and promoting inclusive digital experiences.

Types:

• Screen Reader Testing: Compatibility with voice assistance tools
• Keyboard Navigation Testing: Full functionality without mouse
• Color Contrast Testing: Readability for visually impaired users
• Text Resize Testing: Functionality with enlarged text
• ARIA Labels Testing: Proper semantic markup for assistive tech
