Step Into, Step Over and Step Out:-

Create a new test and function library as mentioned below .Give a breakpoint at line no. 8 as shown below.

 

Example of Step Into –

Run the test and it will pauses at line no 8,

Now press F11 (Step Into), line no. 8 gets executed and cursor will go to the next line “first line inside the function”. Again if we press F11 line no. 2 gets executed and cursor will go to the next line.

So, Step into (F11) only executes the current line and if current line calls a function, the cursor will go to the first line of called function.

Example of Step Out –

Run the test again and when test pauses at line no.8 ,press F11, Line no.8 gets executed the cursor will go to the first line of Action function .Now Press Step Out(Shift+F11) and all the lines inside the function will get executed .

Now run the test again by un commenting the lib function inside Action function.

The test pauses at line no. 8 and we need to press F11 and the cursor will go to first line of Action function .If we press (Shift+F11) ,line no. 2, 3,4 will get executed and cursor will go to the first line of lib function and test will again pauses there .

Now if we press (Shift+F11) the full lib function and remaining two lines (5, 6) of Action function will get executed.

So, Step Out can be only used after the step into (to enter into the called Action or Function) operation .Step out runs till the end of the called Action or Function library and then return to the calling Action of function and pauses the test.

Example of Step Over –

Run the test and when test pauses at line no. 8, press Step Over (F10), It will execute the full Action function at one go, Since Action function contains lib function, so lib function will also get executed.

So, Step Over runs the current step and if current step calls any library, the called library gets executed in its entirety. Step Over does not show the library while running it.
