What are the Different Types of Software Testing?

Software testing encompasses both the process followed and the specific tests conducted to verify every aspect of an application.

Before examining individual testing methods, it is useful to understand the overarching life cycle that governs when and how those tests occur.

Software Testing Life Cycle (STLC): Phases & Methodologies

The STLC defines a structured sequence of activities (from planning through closure) so testers deliver consistent, repeatable quality checks at each stage.

Below are the core phases and popular approaches applied in the STLC:

• Planning (STLC Phase): Outlines test strategy, resources, schedules and entry/exit criteria based on requirements.
• Analysis (STLC Phase): Identifies testable conditions and prioritizes scenarios by risk and impact.
• Design (STLC Phase): Creates detailed test cases, scripts, and data sets for execution.
• Implementation (STLC Phase): Sets up the test environment, reviews test artifacts, and prepares for execution.
• Execution (STLC Phase): Runs test cases, logs results, and compares actual outcomes to expected behavior.
• Closure (STLC Phase): Assesses metrics, compiles final test reports, and archives deliverables.
• V-Model (Methodology): Mirrors each development phase with a corresponding test phase for parallel validation.
• Shift-Left Testing (Methodology): Integrates testing activities earlier — during requirements and design — to catch defects sooner.
• Continuous Testing (Methodology): Embeds automated tests into CI/CD pipelines for rapid feedback on code changes.

Common Testing Types

Each testing type targets a different layer of application quality, ensuring full coverage from code units to user experience.

Testers routinely perform these tests:

• Unit Testing: Verifies individual components or functions in isolation.
• Integration Testing: Checks interactions between modules, services, or APIs.
• System Testing: Validates the complete, integrated application against its specifications.
• Regression Testing: Ensures that recent changes haven’t introduced new defects.
• User Acceptance Testing (UAT): Confirms the solution aligns with business requirements and end-user needs.
• Performance Testing: Measures responsiveness, stability, and resource usage under normal and peak loads.
• Security Testing: Identifies vulnerabilities through penetration tests and automated scans.
• Usability Testing: Assesses how intuitive and user-friendly the interface is for real users.
• Compatibility Testing: Verifies consistent behavior across browsers, devices, and operating systems.
• Scalability Testing: Evaluates how performance holds up as workload or data volume increases.
• Exploratory Testing: Uses unscripted, creative approaches to uncover unexpected issues.
• Automation Testing: Executes repeatable tests via scripts and frameworks to boost coverage and efficiency.
