| /** |
| * This test is from the group of so-called Borland's scenarios and |
| * implements the following test case: <br> |
| * Suite 3 - Hot Swap <br> |
| * Test case: TC10 <br> |
| * Description: Changing data type <br> |
| * Steps: 1.Set breakpoint on line 20 <br> |
| * 2.Debug Main <br> |
| * X. Stops on line 20 <br> |
| * 3.Change line 16 to boolean i = true; <br> |
| * 4.Smart Swap <br> |
| * 5.Resume <br> |
| * X. Prints "true" as last line of output <br> |
| * <br> |
| * The description was drown up according to steps under JBuilder. |
| * |
| * Of course, the test has own line numbers and method/class names and |
| * works as follow: |
| * When the test is starting debugee, debugger sets breakpoint at |
| * the 35th line (method <code>main</code>). |
| * After the breakpoint is reached, debugger redefines debugee changing |
| * type of local variable and resumes debugee. |
| * After resuming debugee sends value of the variable via IOPipe channel, |
| * debugger reads this value and compares it with expected the one. |
| * In this case expected value is the value before redefinition. |
