Conversion testing is primarily focused on ensuring that data migration from one system to another is performed accurately and completely. This involves verifying that data in the original system is transformed and transferred correctly to the new system without any loss or corruption. The objective of conversion testing is to validate the integrity of data post-migration, ensuring that all records are appropriately moved and that the new system reflects the data's intended state.

In contrast, testing user interface design involves assessing how effectively a user can interact with the software, which does not relate to the conversion process. Integration testing assesses how well different software modules work together, focusing on their interactions rather than data migration. Stress testing evaluates how a system performs under heavy load, measuring system robustness and performance, which again is distinct from the purpose of conversion testing. The emphasis in conversion testing is specifically on data accuracy and integrity, making it a critical phase in the implementation of new systems.
