To connect the master plan to a sub-plan file, you enter an include statement in the master plan at the point where the sub-plan logically fits. The include statement cannot be entered through the Testplan Detail dialog box; you must enter it manually.
The include statement uses this syntax:
include: myinclude.pln
where myinclude is the name of the test plan file that contains the sub-plan.
If you enter the include statement correctly, it displays in red, the default color used for the test plan editor statements. Otherwise, the statement displays in blue or black, indicating a syntax error (the compiler is interpreting the line as a description, not a statement).
