Which phase brings all the project pieces together into a special testing environment to eliminate errors and bugs and verify that the system meets all the business requirements defined in the analysis phase?

Question

In project life cycles, different phases serve distinct purposes related to design, build, and verification activities.
Option 1: Design phase. While the design phase specifies how the system will meet requirements, it does not bring pieces together in a testing environment; its focus is on architecture, interfaces, and detailed design rather than integration testing.
Option 2: Development phase. The development phase is where the actual code or components are built. It precedes testing, but the goal here is creation, not the consolidated testing environment used to verify requirements.
Option 3: Implementation phase. The term implementation can refer to deploying components or delivering the system, but the question asks about assembling everything into a special environment for testing and verification, which goes beyond mere deployment and into comprehensive validation.
Option 4: Testing phase. This phase is specifically about validating that the integrated system behaves correctly in an environment that mirrors production, with the aim of eliminating defects and ensuring alignment with business requirements defined earlier during analysis. It involves system integration testing, user acceptance testing, and verification against the defined requirements, which matches the description given.
