Testing and Debugging ABAP Codes, Functions

First test your code with '/h' type in command window which shall take you to debug or by putting break points with F8. You test your program from code and then go to se30 performance analysis transaction and there you can know what are the drawbacks. Then go to SLIN transaction and do extended syntax check or from code in menu options where you have debugging -> extended check and the program id ready without error.

Testing your code.
As mentioned above after doing syntax check and extended syntax check you have to create a TEST PLAN. You have to test all possible Postive & Negative test cases.

Test for division by zero if it involves calculation or code accordingly.
Try to test for field overflows. If it involves sap script or smart forms try to print outputs which have single page and also multiple page and which does not have any output at all.

Test by leaving all parameters in selection screen blank.
Test by entering wrong values in selection screen and display a pop-up if the user enters wrong selection screen values.
You can also do ABAP trace and SQL trace to make sure that your program is efficient.
Debugging code/program.
As mentioned above type /h in command line and try to execute the program. Another way is to set break-point at the function module or the required line and do single step execute or execute. Once you finished debugging, you can select Delete to clear all the break points.

Third option in certain cases is to check for sy-subrc <> 0 and proceed from there by making it 0 by updating the sy-subrc in the debug editor and see how the program behaves if the value is what you enterd in the debug screen. For certain case try to use WATCH POINT feature in debug editor.
