AWS Certified Developer Associate DVA-C02 Practice Question
To verify the accuracy of a function tasked with handling file processing and database updates, which practice should a developer employ to simulate interactions with the storage and database services during automated tests?
Create various branches and aliases for the function to segregate operational environments during the testing phase.
Implement a strategy for stepping through the function code with a debugger to inspect the file processing and updates.
Incorporate a mocking framework to replicate the behavior of file storage and managed database services within the test suite.
Generate live instances of file storage and managed database services and execute test cases against them.
Utilizing mocking frameworks to create simulated versions of storage and database services enables the verification of application logic without affecting live resources. This method tests how the function would behave with different inputs while avoiding direct impacts on actual resources, which could lead to unintended data manipulation and unnecessary costs. Creating real instances for testing can be resource-intensive and is not as efficient for automated unit testing purposes. Versioning and employing branching strategies are more pertinent to deployment management and not specific to the act of automated testing itself. Debugging provides a way to examine code execution line by line, but it is not an automated approach and does not endorse testing best practices.
