Integrating Edge Case Testing with Unit and Integration Tests
In application development, testing is a foundation of delivering solid, quality applications. While unit testing ensures individual components work as intended and integration tests verify that these components act well together, there's another element that is largely neglected: edge case testing. Edge cases are the wacky, unusual, or on-the-fence conditions which might not arise that frequently but can lead to catastrophic failures if not addressed. Including edge case testing in unit and integration testing methodologies is crucial to build robust, fault-tolerant software. Knowing Edge Case Testing Edge case testing is identifying situations that don't fit usual patterns of use. These are things that may stress your application to its limits, such as handling very large inputs of data, corrupted user input, network timeouts, or unexpected responses from an API. The goal is for the software to behave sensibly and securely in extremis. For instance, for a banking app. In nor...
