/**
|
|
* This test is from the group of so-called Borland's scenarios and
|
|
* implements the following test case:
|
|
* Suite 1 - Breakpoints (single threads)
|
|
* Test case: TC1
|
|
* Description: Line breakpoint & step into
|
|
* Steps: 1.Set breakpoint on line 19
|
|
* 2.Debug Main
|
|
* X. Stops on line 19
|
|
* 3.Run | Step into three times
|
|
* X. Steps into Class1 constructor
|
|
*
|
|
* When the test is starting debugee, debugger sets breakpoint at
|
|
* the 48th line (method <code>performTest</code>).
|
|
* After the breakpoint is reached, debugger creates "step into" request
|
|
* and resumes debugee. <code>StepRequest</code> is created with specified
|
|
* <code>addClassFilter</code>. For the third <code>StepEvent</code> debugger
|
|
* checks line number of one's location. It should be 56th line.
|
|
*
|
|
* In case, when line number of event is wrong, test fails.
