Substantive testing is the method primarily utilized to gather evidence regarding the completeness, accuracy, or existence of activities during the audit period. This approach involves directly examining the financial information or transactions to substantiate their validity and ensure they comply with relevant standards and regulations.

By performing substantive tests, auditors can verify the accuracy and legitimacy of recorded amounts, confirming that transactions have occurred and have been recorded in the correct accounting periods. Techniques within substantive testing include analytical procedures and tests of details, which provide comprehensive insights into the financial elements under examination.

While other methods like control testing focus on evaluating the effectiveness of internal controls, they do not directly assess the transactions or account balances in the same detailed manner as substantive testing. Similarly, attribute sampling is more about assessing characteristics of populations rather than confirming specific transactional details, and data analysis, while useful, generally supports audit findings rather than directly serving as a primary test for completeness or accuracy. Thus, substantive testing stands out as the most fitting choice for gathering the necessary evidence in these areas during the audit process.
