🧪Phase 5: Testing

The testing phase of the Software Development Life Cycle (SDLC) is where the software system is tested to ensure that it meets the requirements and quality standards set by the customer. This phase is critical, as it ensures that the software system is stable, reliable, and functional.

Testing Phase Activities

• Unit Testing: This involves testing individual software components or modules to ensure that they behave as expected. Unit testing is typically carried out by developers.

• Integration Testing: This involves testing the interfaces between the various software components and modules to ensure that they work together as expected. Integration testing is typically carried out by developers.

• System Testing: This involves testing the entire software system to ensure that it meets the requirements and quality standards set by the customer. System testing is typically carried out by independent testers.

• Acceptance Testing: This involves testing the software system with real-world data and scenarios to ensure that it meets the needs of the customer. Acceptance testing is typically carried out by the customer.

The output of the testing phase is a fully tested software system that meets the requirements and quality standards set by the customer. This system includes all the software components and modules, database structures, and user interface, and has been integrated into a cohesive system.
