How to get Thoughtworks' White to LogStructure

Struggled for some time getting it to work. I've been playing with Thoughtworks' open library for UI Testing for a while.

Sometimes UISpy doesn't get you to the UIElement hierarchy and you need to take out the big guns ala White's window.LogStructure to dump out the UIElement tree.
As always it's simple when you know how.

Step#1: Modify the app.config of your executable to include the sections related to White. See a sample file on White's page here.

Step#2: Add the following line to your AssemblyInfo.cs file

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4Net.config", Watch = true)]

Step#3: Add a file called Log4Net.config under your assembly (configure it such that it is always copied to the output folder). This contains the configuration information for Log4Net (e.g. the following config logs to console and to file named example.log in your output folder.). That's it you should now be able to see/capture window.LogStructure output from White. Godspeed !

  <appender name="Console" type="log4net.Appender.ConsoleAppender">
    <layout type="log4net.Layout.PatternLayout">
      <!-- Pattern to output the caller's file name and line number -->
      <conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />

  <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
    <file value="example.log" />
    <appendToFile value="true" />
    <maximumFileSize value="100KB" />
    <maxSizeRollBackups value="2" />

    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%level %thread %logger - %message%newline" />

    <level value="DEBUG" />
    <appender-ref ref="Console" />
    <appender-ref ref="RollingFile" />


  1. Thanks! Trying to automate some Devexpress code; hope this will work

  2. Still struggling to get basic console + logging going; ANY chance I could contact you via Email?

    1. Sure. updated my blogger profile with an email id.
      Although not sure how helpful I can be.. have been out of the automation loop for years
