IWTTLog Interface (COM)

The IWTTLog interface implements a COM interface for logging messages and errors.

IWTTLog contains the following public methods.

Method	Description
AddErrorToErrorList	Adds a specified error to a list of known errors.
Assert	Checks the specified condition and, if the condition is false, fails the test case unless a trace is logged or you specifically declare the test case to be skipped.
CheckResult	Checks a specified result and logs an error if the result shows a failure.
CheckResultEx	Checks a specified result against a target result and logs an error if both the value and type match.
ClearErrorList	Removes all errors of the specified type from a given list of known errors.
CloseLogDevice	Closes a log device topology that the device string or the handle specify.
CreateLogDevice	Creates a log device topology according to the device string.
EndTest	Traces the end of a test case, clears the current test case context, and sets it to the parent context.
EndTestEx	Traces the end of a test case and enables you to specify a GUID-based test ID and a test hierarchy.
GetCurrentContext	Retrieves the current context of the logger object.
RemoveErrorFromErrorList	Deletes the specified error from a list of known errors.
SetContext	Sets the current context of the logger object for all subsequent traces.
SetDeviceOption	Sets the current context of the logger object for all subsequent traces.
StartTest	Traces the start of a test case.
StartTestEx	Traces the start of a test case and enables you to specify a GUID-based test ID and a test hierarchy.
Trace	Logs a trace of the specified device at the given trace level.
TraceMachineInfo	Sets the given information about the specified trace computer.
UserDefinedTrace	Logs trace data by using a user-defined trace level.
