C programming Parking Manager.
Write a unit test for allocVehicle()
Remember:
Make use of the assert() function when writing unit tests. It accepts a single Boolean expression as an argument and will halt execution of the program if the expression evaluates to false. If the expres- sion evaluates to true, program execution continues as normal. assert() is best used for testing purposes and should be used sparingly in production code. You must import the C library assert.h to use assertions.
