Software testing is an essential part of the Software Development Life Cycle (SDLC) to ensure the quality of a software product. Out of several software testing techniques employed, we will discuss the interface testing technique.
Interface testing verifies the communication between two software systems. Usually, this can be between:
The following diagram provides a bit more clarity:
Consider the architecture in the above diagram. Interface testing ensures the following:
Interface testing is needed for the following reasons:
Interface testing is comprised of several different tests, summarized in the table below:
Test | Description |
---|---|
Unit Test | Every part of the program is tested to make sure that the program functions properly as a whole. |
Functional Test | In this test, it is made sure that every functional requirement listed in the documentation of the software product is correctly implemented and gets executed. |
Security Test | Verifies that the security protocols used several testing techniques (e.g., penetration tests, encryption, access control tests). |
Load Test | In this test, the functional test cases from the functional test are used to gauge the performance of the system on a specified load. |
Runtime Error Detection Test | This test makes sure that errors that only occur at runtime are resolved (e.g., race condition, resource leak, etc.). |
Workflow Test | This test makes sure that the business process workflow conforms to what is implemented by the software. |
