Fixing a bug in production costs up to 30 times more than catching it during development. The global functional testing market is projected to reach $40.4 billion by 2033.
Functional testing services focus on validating that your software performs exactly as specified in your business requirements.
• Black-box testing approach - Testers examine inputs, processing, and outputs without needing internal code knowledge
• Feature validation - Ensures all features function as specified in requirements
• Data handling verification - Confirms proper data processing and storage
• UI interaction testing - Validates user interface behaviors and workflows
• Error handling confirmation - Tests that error conditions are managed gracefully
