CWTTLogger::SetDeviceTraceLevel method

The SetDeviceTraceLevel method sets the specified device trace level for all subsequent traces.

Syntax

HRESULT SetDeviceTraceLevel(
  DWORD dwTraceLvl,
  LONG hDevice
);

Parameters

• dwTraceLvl
  [in] Trace level to be set. This should be one of the following values:

  • WTT_LVL_MSG
    Trace a user-defined message. This type of trace is the most commonly used trace. If all traces within the context of a particular test case are messages, function entry, function exit, TCM information, or machine information, the test case will pass.

  • WTT_LVL_ERR
    Trace an error. This trace causes the logger (in the usermode) to fail a test case unless a bug trace is logged or the user declares the test case as skipped.

  • WTT_LVL_ASSERT
    Trace an assertion. This trace causes the logger (in the user mode) to fail a test case unless a bug trace is logged or the user declares the test case as skipped.

  • WTT_LVL_INVALID_PARAM
    Trace an invalid parameter. This trace causes the logger (in the user mode) to fail a test case unless a bug trace is logged or the user declares the test case as skipped.

  • WTT_LVL_BUG
    Trace a known bug. This trace causes the logger (in the user mode) to log a test case as blocked, unless the user declares the test case as skipped.

  • WTT_LVL_BREAK
    Trace a debug break. This trace causes the logger (in the user mode) to fail a test case unless a bug trace is logged or the user declares the test case as skipped.

  • WTT_LVL_WARN
    Trace a warning message. This trace causes the logger (in the user mode) to log the test case as warned, unless an error or bug trace is logged or the user declares the test case as skipped.

  • WTT_LVL_FUNCTION_ENTRY
    Trace the function entry point. This trace does not affect the test case result.

  • WTT_LVL_FUNCTION_EXIT
    Trace the function exit point. This trace does not affect the test case result.

  • WTT_LVL_START_TEST
    Trace the start of a test case. This trace marks the beginning of a test case and sets a new context whose name is the current test case name. However, you should call the StartTest method instead of using this level.

  • WTT_LVL_END_TEST
    Trace the end of a test case. This trace marks the end of a test case and clears a new context whose name is the current test case name. It also updates the internal pass-fail counter according to the pass-fail mode and the previous traces. However, you should call the EndTest method instead of using this level.

  • WTT_LVL_TCMINFO
    Sets the Tactics fields. This value does not affect the test case result.

  • WTT_LVL_MACHINEINFO
    Sets machine-related test case fields for Tactics. This value does not affect the test case result

  • WTT_LVL_ROLLUP
    Trace the test suite roll-up information. If the pass-fail mode is set to user, your plug-in must provide its own pass-fail count. Otherwise, DTM Logger will overwrite the counters that you provide and use its internal counts. However, this value does not cause DTM to perform a rollup operation.

• hDevice
  [in] A handle to the device tracing topology. You can combine multiple handles by using the bitwise OR operator (for example, hDevice1 OR hDevice2).

Return value

SetDeviceTraceLevel returns one of the following values:
