Arguments to tests

A test without arguments, are declared like this void test(void). A test can also be declared with arguments as shown in sample202.1below 
  void test_deg2rad(double degrees, double radians, double *error) {
    double result = deg2rad(degrees);
    *error = result-radians;
    VALIDATE_FP(result , radians);  
    }

  void testmain(void) {
    double rounding_error;
    EXECUTE(test_deg2rad, 360, 2*PI, &rounding_error);
    COMMENT("Rounding error is %f\n", rounding_error );
    }
If the test are executed repeatedly, e.g. they have been setup with a PARAMETER macro, each call will use the same function arguments. By passing PARAMETER_VALUE as a one of these, this argument can be made to vary with each test run, e.g. in sample212.1 
  void test_deg2rad(double degrees, double radians) {
    double result = deg2rad(degrees);
    VALIDATE_FP(result , radians);  
    }
 
  void testmain(void) {
    PARAMETER_RANGE_FP(2*PI, 10*PI, 2*PI);
    EXECUTE(test_deg2rad, 360, PARAMETER_VALUE_FP);
    }

TestApe will pass commandline arguments after the --args tag to testmain, so if the test executable are invoked like this 

./sample22 --args 4
argc will be 1 and argv[0] will be "4" in the testmain function declared in sample222.1below 
  void test_deg2rad(double degrees, double radians) {
    double result = deg2rad(degrees);
    *error = result-radians;
    VALIDATE_FP(result , radians);
    }

  int testmain(int argc, char *argv[]) {
    double rounding_error;
    int number = atoi(argv[0]);
    EXECUTE(test_deg2rad, 360, number*PI, &rounding_error);
    COMMENT("Rounding error for number equals %d is %f\n", number, rounding_error);
  }
