Incorporate Testing and Debugging

Use Unit Testing:

• Incorporate unit testing frameworks like fortran-test to ensure code correctness and catch bugs early.

Example:

fortranCopy codemodule test_module
    implicit none
    contains
    function add(x, y) result(sum)
        integer, intent(in) :: x, y
        integer :: sum
        sum = x + y
    end function add
end module test_module

program test
    use test_module
    implicit none
    integer :: result

    result = add(2, 3)
    if (result /= 5) then
        print *, 'Test failed!'
    else
        print *, 'Test passed!'
    end if
end program test
