Generating the test executable

To generate the test executable, the following is needed : the code being tested, the test, and the testape framework. These are combined to form the test executable using the instrumenter together with the compiler or linker.

calc.c shown below will be used in the following examples. The calculator will perform a simple addition or subtraction. It will do that calling invalid(), add(), subtract(),divide() and multiply(). The calculator program is normally assembled of calc.c, add.c, subtract.c, multiply.c and divide.c, but calc.c and add.c are the only files in the unit being tested in the following samples.

  int validate(int a, int b)  { return 1; }

  int calculate(int operand1, int operand2, char operation) {
    if ( invalid(operand1) || invalid(operand2) )
      return ERROR;
    switch(operation) {
      case '+':
        return add(operand1, operand2);
      case '-':
        return subtract(operand1, operand2);
      case '*':
        return multiply(a,b);
      case '/':
        return divide(a,b);
    return ERROR;

Sample1 is shown here, 2.1

  #include "testape.h"

  void test_addition(void) {
    int result;
    result = calculate(3,7,'+');

  void testmain(void) {

can be compiled and run in an MinGw-w64/gcc environment like it is shown below. Notice that multiply.c, divide.c, and subtract.c are not compiled. Instead the instrumenter is invoked in front of the compiler. The instrumenter will launch the compiler and generate default mocks for the missing functions in the unit.
