Interface errors in software testing

In a C program, programmers can write a statement include header. Since the interface specification lies somewhere away from the actual code, programmers overlook the interface specification while writing code.

These are errors caused by implicit assumptions in one part of a system that another part of the system would perform a function. Disagreement on or misunderstanding about the location of a functional capability within the software leads to this sort of error.

The problem arises due to the design methodology, since these disputes should not occur at the code level. It is possible that inexperienced personnel contribute to the problem. Changing one module without correctly adjusting for that change in other related modules affects the functionality of the program. A completely new functional module, or capability, was added as a system modification.

Any added functionality after the module is checked in to the version control system without a CR is considered to be an error. One module makes an error in using the interface of a called module. Interface misuse can take the form of wrong parameter type, wrong parameter order, or wrong number of parameters passed.

A called module may return an error code to the calling module. However, the calling module may fail to handle the error properly. Integration testing or incremental testing is necessary to verify whether the software modules work in unity. Some programming languages, such as C, generally separate the interface specification from the implementation code.
