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 (f.directory) {
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! :)

Groovy Posts & Links

I'm following the Groovy (http://groovy.codehaus.org/) posts and links on http://www.dzone.com/ and http://del.icio.us/. It is amazing, how the number of posts and saved URL's increased over the last couple months.

If you would like to have a look at these, check the following links...

Enjoy reading!

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 (http://webtest.canoo.com/) 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:

WebTestReport.xml:








...










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 = [:]
entry.name = 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 (element.name() != 'parameter') return false
if (element.'@name' != 'taskName') return false
def roundtripTags = 'clickLink clickButton clickElement'
roundtripTags.tokenize().contains(element.'@value')
}
entry.roundtrips = rt.size()

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

def verifies = testcase.depthFirst().findAll { element ->
if (element.name() != 'parameter') return false
if (element.'@name' != 'taskName') return false
def fieldsTags = 'verifyCheckbox verifyCookie verifyDocumentURL verifyElement'
fieldsTags.tokenize().contains(element.'@value')
}
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" <<
"Beschreibung\n"
for (entry in resultLines()) {
writer <<
entry.name << "\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
}
