SUT : Software Unit Test

Techniques in Unit Testing

  • White-box Testing: Tests are based on knowledge of the internal logic of an application's code. This involves

    • testing the structure, flow, and data within the unit.

  • Black-box Testing: Tests are based on requirements and functionality without knowing the internal workings of the application.

  • Gray-box Testing: Combines both white-box and black-box testing techniques.

Writing Unit Tests in C

  • Arrange, Act, Assert (AAA): This is a common pattern used in unit tests.
    • Arrange: Set up the test environment and initialize objects.
    • Act: Execute the unit being tested.
    • Assert: Verify the result.

Planning the test cases

image

  • assert:
    • assert.h
    // arrange
    int expected = 5;
    // Act
    int result = add(a, b);

    /*
    * assert funtion:
    * it takes a condition as an argument and if the condition is false,
    * the program will terminate with an error message. 
    * Assertion failed: result == expected, line 37
    */
    assert(result == expected);
