Recursive search on the filesystem for the content of a log-file

I had the following problem lately:

On a test server I was looking for a log-file on the installation path and/or one of its sub-folders with some information about a "session timeout".

I didn't know the the log-files name, but new, that it had the extension ".log". I also didn't know which exception was was creating the entry. All I had, was the string "session timeout".

With the following Groovy script I could find all the log-files containing the string "session timeout" and from there it was easy to identify the log-file.

def dir = 'C:/some_installation_folder'
def fileExtension = '.log'
def searchString = 'session timeout'

new File(dir).eachFileRecurse() { f ->
if ( {
def p = ~/.*\${fileExtension}/
f.eachFileMatch(p) { log ->
def exceptions = []

log.eachLine { ln ->
if (ln =~ '.*' + searchString + '.*') {
exceptions << "${ln}"

if (!exceptions.empty) {
println log
exceptions.each{println " $it"}

Enjoy! :)

Date Format Fix in Excel 2003

Due to an issue in Excel 2003, sometime the date formats are not updated in the cells, which leads to the problem, that a cell shows a date but is not read as a date by macros and formulas.

You could go through each cell, press 'F2' and 'Enter' and Excel would finally identify the content of the cell as a date. But this you would do manually and not by script.

With the following VBA script for Excel, the format can be updated:

Sub UpdateColumnFormat()

Dim usedRangeOfRows As Integer
usedRangeOfRows = ActiveSheet.UsedRange.Rows.Count

Dim e As Range
Dim currentValueE As Date
For Each e In Range("A2:A" & usedRangeOfRows).Cells
currentValueE = ActiveCell.Value
ActiveCell.FormulaR1C1 = currentValueE

End Sub

This problem occurs regularly, when I copy data from one sheet to another by VBA scripts.

With the above script, I could fix (at least work around it) this issue.

Enjoy :)

"Create List..." in Excel 2003 with VBA

While working on data within Excel with VBA, I like to use dynamic lists to address the data and eventually to give it a name.

To create a list, the same one as you would do manually by calling "Create List..." from the context menu, you can execute the VBA script below.

Private Sub CreateList()


Range(Selection, Selection.End(xlDown)).Select
Range(Selection, Selection.End(xlToRight)).Select

Dim NumberOfColumns As Integer
Dim NumberOfRows As Integer
Dim StartCell As Range
Dim EndCell As Range

NumberOfColumns = ActiveSheet.UsedRange.Columns.Count
NumberOfRows = ActiveSheet.UsedRange.Rows.Count

Set StartCell = Cells(1, 1)
Set EndCell = Cells(NumberOfRows, NumberOfColumns)

Dim DataRange As Range
Set DataRange = Range(StartCell, EndCell)

ActiveSheet.ListObjects.Add(xlSrcRange, DataRange, , xlYes).Name = "List1"
Range(StartCell, EndCell).Select
ActiveWorkbook.Names.Add Name:="Data", RefersToR1C1:=DataRange

End Sub

I also give the list the name "Data", which I do to access the data by name afterwords, but this is not required to create the list.

Enjoy :)

Read File Properties with Excel VBA

The VBA script for Excel below will read the 'File Version' from the file properties and will read file name and its version each into a column in a Excel sheet.

Sub getFileProductVersion()

Dim objShell As Shell
Dim objFolder As Folder
Dim objFolderItems As FolderItems
Dim objFolderItem As FolderItem
Dim numberOfFiles As Long
Dim i As Integer
Dim j As Integer

Set objShell = New Shell
Set objFolder = objShell.Namespace("C:\Temp\files")

If (Not objFolder Is Nothing) Then
Set objFolderItems = objFolder.Items()
numberOfFiles = objFolderItems.Count

For i = 0 To numberOfFiles - 1
Set objFolderItem = objFolderItems.Item(i)
ActiveCell.Offset(i, 0) = objFolderItem.Name
ActiveCell.Offset(i, 1) = objFolder.GetDetailsOf(objFolderItem, 39)
Next i

End If

Set objFolder = Nothing
Set objShell = Nothing

End Sub

Enjoy :)

How to specify the browser that should be used in WebTest

In WebTest it is possible to define which browser shall be simulated. Currently WebTest support the following browsers:
  • Firefox3 (or FF3)
  • Firefox2 (or FF2)
  • InternetExplorer6 (or IE6)
  • InternetExplorer7 (or IE7)
To get a more detailed list, have a look at the WebTest config page (

As you can see in the simple example below, it is very easy to define the simulated browser for your test:

'Here goes your test code...'

This example is an extract from a browser test of the self test suite of WebTest. For more details, have a look a the self test suite (

Functional Testing for Joomla! with WebTest

Joomla! is a very popular open-source CMS based on PHP. It is simple to use and makes creating and maintaining Web sites easy for everyone, from total beginners setting up their first site to IT professionals managing enterprise installations.

Like many other projects (not only open-source projects) testing is not the most popular subject. However, testing is very crucial for every project to be able to grow and handle complexity within the project.

Functional testing is one aspect of testing which can focus on the users perspective of using an application.

I started a functional test suite for Joomla! with Canoo WebTest, an open-source tool for automated testing of web applications in a very effective way.

If you would like to have a look at the current state of the work, see here:
Some initial documentation can be found here:

WebTest vs. Selenium

Marc Guillemot compares the features of two popular open source testing tools: WebTest and Selenium!

A must read post! Very interesting!

[..] The maintainability of automated tests depends primarily on the skills of the test authors, but different tools have different features that impact their efficiency. This blog post compares the features of two open source automated web testing tools: Canoo WebTest and Selenium.

Dealing with critics?

There is an interesting post on Marc Guillemot's blog:

He's blog entry can be understood in a way, that the lack of XPath can be associated to the lack of test automation experience. If this relation is correct or not is not as interesting as the reaction which has raised based on his entry.

I'm very surprised, how personal this was taken, especially the comment of Neil: I would have expected more distance to such a statement and more tolerance.

My understanding of Marc's statement is, that the better an XPath expression is (better in the sense of robust), the better the tests are which might be based on the XPath expression. The first XPath statement Marc is quoting:

is not robust at all. If there a small change in the used tables or additional items in the lists, the test will break. If there is a relationship between robust and better, that this statement is not prefered and in this sense, I can understand the statement of Marc very well.

Groovy in Action

The book "Groovy in Action" is finally out! Have a look, it's worth reading it!



Groovy in Action is a comprehensive description of the Groovy programming language, its libraries, and its everyday use. With the release of JSR 241, Groovy has become the second standard language for the Java platform. The book introduces Java developers to the new dynamic features that Groovy brings to this platform.

Groovy: Parsing an XML file with Groovy

Groovy comes with a handy XML parser. With this parser you can load an XML file quickly and navigate it easy.

Currently I'm working with WebTest ( for testing functional aspects of an web application.

WebTest comes with a nice overview to present the results of the test runs. The report itself is transformed out of an XML file. For statistics reason, I'm using this XML file to extract specific data. This extraction is done with a little Groovy script.

To get an idea of the WebTest report XML file, have a look a the fragment below:



name="resultFilename" value="response_1156746643278_invoke.html"/>


This file can be parsed with the following code:

import java.text.SimpleDateFormat

FormatUS = new SimpleDateFormat('EEE MMM dd hh:mm:ss z yyyy', Locale.US)
FormatDE = new SimpleDateFormat('dd.MM.yyyy hh:mm:ss', Locale.GERMAN)

def folder = args?.size() ? args[0] : "data"
println "reading files from directory '$folder'"
def basedir = new File(folder)

// result files of the current run
files = basedir.listFiles().grep(~/.*xml$/)

List resultLines() {
List result = []
for (currentFile in files) {
println " processing $currentFile"
def summary = new XmlParser().parse(currentFile)

// List with all 'testresult' elements
def testresults = summary.testresult

testresults.each { testcase ->
def entry = [:] = testcase.'@testspecname'.split(/\W/)[0]
entry.time = testcase.'@starttime'
entry.time = FormatUS.parse(entry.time)
entry.time = FormatDE.format(entry.time)
entry.ok = testcase.'@successful'

def rt = testcase.depthFirst().findAll { element ->
if ( != 'parameter') return false
if (element.'@name' != 'taskName') return false
def roundtripTags = 'clickLink clickButton clickElement'
entry.roundtrips = rt.size()

def fields = testcase.depthFirst().findAll { element ->
if ( != 'parameter') return false
if (element.'@name' != 'taskName') return false
def fieldsTags = 'selectForm setCheckbox setFileField setInputField setRadioButton'
entry.fields = fields.size()

def verifies = testcase.depthFirst().findAll { element ->
if ( != 'parameter') return false
if (element.'@name' != 'taskName') return false
def fieldsTags = 'verifyCheckbox verifyCookie verifyDocumentURL verifyElement'
entry.verifies = verifies.size()

if (testcase.results.error) {
entry.resultsError = testcase.results.error.'@exception'[0]
} else {
entry.resultsError = ''

if (testcase.results.failure) {
entry.resultsFailure = testcase.results.failure.'@message'[0].replaceAll(/\W/, " ")
println "####" + entry.resultsFailure
} else {
entry.resultsFailure = ''

def groupSteps = testcase.results.step.findAll { step ->
step.parameter.any { param ->
param.'@name' == 'taskName' && param.'@value' == 'group'

def goodSteps = groupSteps.findAll{ it.result?.completed }

// assumed: there is always at least one group step, size() never 0
if (groupSteps.size() != 0) {
entry.complete_pct = goodSteps.size() / groupSteps.size()
} else {
entry.complete_pct = 0

if (goodSteps) {
entry.description = goodSteps[-1].parameter.findAll{it.'@name'=='description'}.'@value'[0]
} else {
entry.description = ''

result <<>
writer <<
"Testfall\t" <<
"Datum\t" <<
"Erfolgreich\t" <<
"Prozent\t" <<
"Error\t" <<
"Server Roundtrips\t" <<
"Number of Fields\t" <<
"Verifications\t" <<
for (entry in resultLines()) {
writer << << "\t" <<
entry.time << "\t" <<
entry.ok << "\t" <<
entry.complete_pct << "\t" <<
entry.resultsError << "\t" <<
entry.roundtrips << "\t" <<
entry.fields << "\t" <<
entry.verifies << "\t" <<
entry.description << "\n"

Now you get a tab seperated file with the content of your result files from the web testing runs. I
import this file into Excel and create a pivot table to understand the results better.

I hope this helps :)

Groovy: Get all XML files from a directory tree

Currently I'm working in a project, where Groovy (a dynamic scripting language for the JVM) is used. One of the project members is Dierk König, which is a Groovy commiter and the author of Groovy in Action. This gives a real insight in the beauty of Groovy :)

Below you can see a nice solution for finding all XML files in a directory tree:

// pass a directory or use the current directory
def folder = args?.size() ? args[0] : "."
println "reading files from directory '$folder'"
def basedir = new File(folder)

// result files of the current run
files = basedir.listFiles().grep(~/.*xml$/)

List resultLines() {
List result = []
for (currentFile in files) {
println " processing $currentFile"
return result

Setting up the master Maven 2 project for WebTestClipse - Install Maven 2

I'm setting up the master Maven 2 project for WebTestClipse . You can follow these steps to set up any kind of project.In this post I'll descripe the installation of Maven 2, based on links and some minor notes. It's not to be considered to be a complete installation guide.

1.) Download Maven 2

Download Maven 2 from and chose the right distribution. I'm using .

2.) Unpack Maven into a local directory

I've chosen C:\dev\maven-2.0.4 as my Maven 2 home directory.

3.) Environment Variable

Define a %MAVEN_HOME% variable and extend the %PATH% variable. This will make it possible to call Maven 2 commands from the command line

4.) Test your Installation

Testing the installation is fairly simple. Just call a Maven 2 command from the command shell:

mvn -v

As a result you should see:

Maven version: 2.0.4

Joined WebTestClipse

I joined the WebTestClipse project. The goal of the project is to provide a set of Eclipse features and plugins to develop tests for WebTest .
