| * @summary converted from VM Testbase nsk/jdi/StepEvent/_itself_/stepevent001. |
| * VM Testbase keywords: [quick, jpda, jdi] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * The test exercises com.sun.jdi.event.StepEvent interface. |
| * The test checks the following assertions: |
| * - StepEvent is received by debugger for requested |
| * location if this location is reached by some executing thread |
| * in debugged VM; |
| * - received StepEvent has proper references to: |
| * debugged VM, |
| * executed thread, |
| * related StepRequest, |
| * checked location. |
| * - StepEvent is generated before the code at its location |
| * is executed. |
| * A debugger class - nsk.jdi.StepEvent._itself_.stepevent001 ; |
| * a debuggee class - nsk.jdi.StepEvent._itself_.stepevent001a . |
| * The test uses supporting nsk/jdi/share classes for launching debuggee |
| * and for creating communication pipe between debugger and debuggee. The |
| * debugger and debugee communicates with special commands. |
| * The debugger launches and connects to debuggee using the default launching |
| * connector. The debugger creates auxiliary BreakpointRequest on location in |
| * <foo> method of <stepevent001a> class where <counter> field is assigned |
| * to zero. The <counter> field in incremented on next lines of this method |
| * until exit. Also debugger creates but disables the StepRequest to receive |
| * StepEvent with size equals to STEP_LINE and depth equals to STEP_OVER |
| * The debugger starts <EventHandler> thread for listening events delivered |
| * from debuggee, sends command <GO> to debuggee and waits for command <DONE>. |
| * Upon receiving <GO> command from debugger, the debuggee invokes <foo()> |
| * method and, after method has been invoked, sends command <DONE> to debugger. |
| * When BreakpointEvent is received by <EventHandler>, it enables |
| * StepRequest. |
| * For each StepEvent received by <EventHandler>, it compares all refencies |
| * of this event ( <method>, <thread>, <request>, <virtualMachine> ) |
| * with expected values. The current value of <counter> field reference |
| * is compared with expected value. |
| * When StepEvent for last checked line is received, <EventHadler> |
| * disables StepRequest to prevent further generation of StepEvents. |
| * When <DONE> command received from debuggee, debugger notifies |
| * <EventHandler> that method is invoked and waits for <EventHandler> |
| * receives all expected events. If not all events received for |
| * WAITIME period, debugger interrupts <EventHandler> thread and |
| * complains about an error. |
| * Finally, debugger disables all requests, sends debuggee command <QUIT), |
| * cleans events queue, waits for deduggee terminates, and exits. |
| * The test fails if any of the checks failed. |
| * COMMENTS |
| * Test fixed due to bugs: |
| * 4455653 VMDisconnectedException on resume |
| * 4463674 TEST_BUG: some JDI tests are timing dependent |
| * Standard method Debugee.endDebugee() is used instead of cleaning |
| * event queue on debuggee VM exit. |
