Applies To

The method is applied to the following object:


The method has the following parameters:


Message text. This text will be added to the Message column of the Test Log. MessageText can hold data of any OLE-compatible type. If it cannot be converted to text, its value is ignored. For example, using this operation, you can add the value of the needed variable to the test log (see the code below).

The parameter does not support multiline text, that is, you cannot post multiline messages to the Message column. To post multiline text to your test log, use the AdditionalInformation parameter.


Additional text to be displayed in the Details pane of the Test Log. Details can hold data of any type compatible with OLE. If it cannot be converted to text, its value is ignored.

The Details parameter can also hold HTML code. The test engine will compile the HTML page and display it in the Details pane. For more information, see Posting Messages to the Log.


Message priority. You can use any integer number or any of the following constants:

Constant Value Description
pmLowest 100 The lowest priority of the message.
pmLower 200 The message priority which is lower than normal.
pmNormal 300 The normal (default) priority of the message.
pmHigher 400 The message priority which is higher than normal.
pmHighest 500 The highest priority of the message.


The font and color settings that will be applied to the newly created informative message in the log. They are represented by a LogAttributes object. If this parameter is omitted, default attributes will be applied.


Specifies the image to be posted to the test log along with the message. This image will be displayed in the Picture pane of the Test Log when that message is selected. You can use one of the following values in this parameter:

  • A Picture object.
  • A window or onscreen object or the Desktop object.
  • The fully-qualified path to the image file. The following image formats are supported:
    • BMP
    • JPEG
    • PNG
    • TIFF
    • GIF
    • ICO

The format of the posted images specified by the mentioned scripting objects is controlled by the image settings of your test project. The format of images taken from existing files is not changed.


Identifier of the test log’s folder to which the message will be posted. To get this identifier, use the CreateFolder or AppendFolder method. If this parameter refers to a non-existent folder, is omitted or is set to -1 (the default value), the Message method will either post the message to the default folder of the test log or append it to the test log outside of any folder (if the default folder is not set). The default folder is the folder that is currently at the top of the folder stack, which is populated during the script run. To push a folder to or pop it out of this stack, use the PushLogFolder or the PopLogFolder method correspondingly.

Result Value



If the Log.CallStackSettings.EnableStackOnMessage property is True, then the test engine collects information about the execution sequence of tests that led to the call of the Log.Message method and displays this information in the Call Stack page of the test log. See Collecting Call Stack Information for Log Messages.

When you call the Log.Message method, the test engine generates the OnLogMessage event.


The following code illustrates the use of the Log.Message method.

JavaScript, JScript

function Main()
  Str="The value to be posted to the log is "


def Main():
  Str="The value to be posted to the log is "
  Log.Message(Str + "123")


Sub Main
  Str="The value to be posted to the log is "
End Sub


procedure Main;
var Str: string;
  Str:='The value to be posted to the Log is ';

C++Script, C#Script

function Main()
  Str="The value to be posted to the log is "

After these tests have been run, the log will contain the The value to be posted to the log is 123 string.
