1. Unit Testing

2. Integration Testing

3. System Testing

4. Functional Testing

The correct answer is: Unit Testing

The term that describes testing that validates the technical quality of the code after component development is complete is unit testing. This type of testing focuses on individual components or functions of the software to ensure they work as intended in isolation. The primary goal of unit testing is to identify any bugs or issues in the code at the earliest stage of development, which helps developers maintain high-quality code and facilitates easier debugging. During unit testing, each small part of the software (the "unit") is tested independently from the other parts, usually through automated tests. This allows developers to verify that the logic of the code performs correctly and meets design specifications. When done effectively, unit tests can lead to reduced costs in the later stages of software development and ensure that individual modules integrate well when combined with the larger system. In contrast, integration testing focuses on the interactions between different components to ensure they work together as expected, system testing assesses the complete and integrated software as a whole, while functional testing evaluates how the software performs against specified requirements.
