What is code-based testing?

Samia Ishaque

Code-based testing involves testing out each line of code of a program to identify bugs or errors during the software development process. Specific test cases are checked on the program to see if it performs the functions required.

Moreover, code-based testing can be broken down into structural and static testing.

Below are the definitions of the terms above and what they consist of as a part of code-based testing.

  • Structural testing: This type of testing is based on the program’s implementation. Structural testing consists of the following:

    • Dynamic testing: Also known as control-flow-based testing, as it checks that each branch of the control flow is covered by the program. Dynamic testing checks for statement, path, and branch coverage in the control flow.

    • Complexity-based testing: A mathematical approach using a control flow graph. Complexity-based testing calculates nodes covered, as well as the distance to the next node.

  • Static testing: Static testing will not require us to execute the program but rather review the code and walk through it. Static testing involves the following:

    • Code walkthrough: Led by a programmer who goes over the code so that team members understand and identify defects better.

    • Code inspection: Led by a moderator who outlines the criteria for entry and exit of data. A document is created highlighting how the code can be improved.

    • Code review: Carried out by programmers to detect each other’s bugs.

    • Code audit: Done to ensure all rules have been followed and that the code meets standards for requirements, security, and programming conventions.
