Fitnesse is the newest automation tool I have introduced here, we also use PowerShell to drive a lot of the builds, because there is some integration between the two (think Smoke Test) I worked on getting the TestRunner working with PowerShell.  I couldn't get the .Net version to run properly, it kept dying when it would render the page, but the Java runner worked great once I was able to work through the java command line with the BuildMaster.  If not for his help I wouldn't have been able to finish.

This script launches the Java TestRunner, points it to the Fitnesse server, and runs the three tests (one Test and two Suites) I currently have set up, then scans through the XML results to display some results in the command line window.

[string]$fitniumLocale = "C: itnium"

[string]$fitnesseJar = "fitnesse.jar"

[string]$fitnesseClass = "fitnesse.runner.TestRunner"

[string]$serverName = "my_server"

[string]$portName = "8888"

$testArray = ( "Test1" , "Test2", "Test3" )

function main()

    Write-Host "Running Fitnesse Tester.`n"

    cd $fitniumLocale

    # Run through each test in the bundle

    $Java = "java.exe"

    foreach ($test in $testArray)

        # Make a date string to get the right file date/format

        $dateStr = [string] (get-date)

        $Month,$Day,$Year,$Hour,$Minute,$Second = $dateStr.split(" :/")

        $testResults = "$test" + "$Month" + "$Day" + "$Year" + "$Hour" + "$Minute" + ".xml"

        [string]$opts = "-xml $testResults"

        # Start the test

        Write-Host "`nRunning $test`n"

        # Get the output from Java so we can scrape it for the test passes and fails

        & $Java "-cp" "$fitnesseJar" "$fitnesseClass" "-xml" "$testResults" "$serverName" "$portName" "$test"

        Write-Host "Completed $test`n"

        Write-Host "Test Results"

        # Scan through the output file, we want that for archiving

        [System.Xml.XmlDocument] $xd = new-object System.Xml.XmlDocument

        $file = resolve-path($testResults)

        $xd.load($file)

        $nodelist = $xd.selectnodes("/testResults/finalCounts") # XPath is case sensitive

        foreach ($testCaseNode in $nodelist)

        {

            $right = $testCaseNode.selectSingleNode("right").get_InnerXml()

            $wrong = $testCaseNode.selectSingleNode("wrong").get_InnerXml()

            $ignores = $testCaseNode.selectSingleNode("ignores").get_innerXml()

            $exception = $testCaseNode.selectSingleNode("exceptions").get_InnerXml()

        # Send a summary of the results to the console

        Write-Host "Passed: $right" -ForegroundColor Green

        Write-Host "Failed: $wrong" -ForegroundColor Red

        Write-Host "Ignored: $ignores"

        Write-Host "Exceptions: $exception" -ForegroundColor Yellow
