According to identified core functions, outline the test scenarios and prioritize them according to their relevance and significance in the overall system functioning.
Make an explicit plan to maintain structure and organization that includes functionalities to be tested, test inputs, expected outputs, and other relevant details.
Add automation testing for sanity testing to save time and resources and reduce human error.
Choose quick and efficient tools for sanity testing as they will help manage and document tests and their results
Always have the record for sanity tests to identify success and failure rates.
Performing sanity testing on core functionalities doesn't open room for leaving minor issues as they can create significant underlying problems.
