How to Record Jmeter Scripts - Tips and Tricks

When using Jmeter I have come across two easy ways to record Jmeter scripts. I will explain these methods and the some tips to make your reording more usefull.

1. Using  blazemeter plugin.

This is a browser plugin that can be used to record Jmeter Scripts. Note that you should have a account created in blazemeter website for this and account creation is free. You can get the plugin for chrome from here.

After Installing the plugin, setup the plugin as shown below and start recording perform the action you want to record in the browser and stop the recording.  After stooping the recording you can download a .jmx file and open it with Jmeter.

2. Using Recording Controller

This is Jmeter inbuild option that is available for recording. To record with Recording  Controller follow the below instructions.

1. Create a Proxy server in the browser. To do this open Browser options and do the following configurations. Note that I'm adding localhost as my proxy host so I should access my website which needs to be recorded through the same domain "localhost".

2. Now right click on the WorkBench and add a "HTTP(S) Test Script Recorder" which can be found under non test elements and set the following configs. Make sure that the proxy port matches the proxy port that was set in step 01.

3. [OPTIONAL] Now add URL exclude patterns as shown below. This is to avoid Jmeter from recording unnecessary HTTP calls. (e.g: Loading javascripts/ Server Pings etc.)

4. [OPTIONAL] Now add a User Defined Variables Element and add any variable you might want to parameterize. What ever variable added here, if the value defined for the variable matches with any content of the recording, Jmeter will automatically parameterize this. This is quite handy when dealing with complex recordings. Make sure this resides in the same Thread group where the Recording Controller is located.

5. Now add a Recording Controller with the project. You can observe this in the above screenshot.

6. Now Start the proxy server and acess the browser and navigate to the website you want to record. Now expand the recording controller and observer the magic happening.

So that's it hope this might help someone, and please drop a comment if you have any other queries.

Enable TouchPad/ Tap to Click under Gnome in Fedora 24

Recently I updated my laptop to Fedora 24 from Fedora 23. And suddenly my tocuhpad stopped working properly. Even touchpad settings were missing under Gnome environment. Although everything worked with wayland I had some issues when working with wayland.

Following is how I got this resolved. Please do the changes with caution and with proper backups.

The primary method of configuration for the touchpad is through an Xorg server configuration file. So lets get started.

1. First locate the synaptics.conf file which is the default configuration and copy it as shown below. After copying you can do the necessary configurations.

sudo cp /usr/share/X11/xorg.conf.d/50-synaptics.conf /etc/X11/xorg.conf.d/

Note that the name of your fila may differ slightly.

2. Now open the copied file and add the following configuration to it. If you already have a config blog edit that section.

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "2"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "30"
        Option "FingerHigh" "50"
        Option "MaxTapTime" "125"
EndSection

Now restart your OS and hopefully everything will work now.

Recieve GMail through Mailto transport -WSO2 ESB

In this Post I will explain How we can receive Emails through WSO2 ESB Mailto transport and perform some operations on it.

1. First lets Enable the transport. Open "repository/conf/axis2/axis2.xml" and uncomment the following section.

<transportReceiver name="mailto" class="org.apache.axis2.transport.mail.MailTransportListener">
        <!-- configure any optional POP3/IMAP properties
        check com.sun.mail.pop3 and com.sun.mail.imap package documentation for more details-->
    </transportReceiver>

2. Now lets create a proxy service to consumes the Emails. You can Copy and paste the following proxy service to source view to create the proxy. Make sure you change access parameters accordingly.

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="JasperEmailPOP3"
       transports="mailto"
       statistics="disable"
       trace="disable"
       startOnLoad="true">
   <target>
      <inSequence>
         <property name="senderAddress"
                   expression="get-property('transport', 'From')"
                   scope="default"
                   type="STRING"/>
         <log level="custom">
            <property name="Date" expression="$trp:Date"/>
            <property name="Subject" expression="$trp:Subject"/>
            <property name="Content-Type" expression="$trp:Content-Type"/>
            <property name="From" expression="$trp:From"/>
         </log>
         <drop/>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
   </target>
   <parameter name="mail.pop3.socketFactory.class">javax.net.ssl.SSLSocketFactory</parameter>
   <parameter name="transport.PollInterval">5</parameter>
   <parameter name="mail.pop3.host">pop.gmail.com</parameter>
   <parameter name="mail.pop3.user">ycwso2test</parameter>
   <parameter name="transport.mail.Protocol">pop3</parameter>
   <parameter name="mail.pop3.socketFactory.port">995</parameter>
   <parameter name="transport.mail.Address">ycwso2test@gmail.com</parameter>
   <parameter name="mail.pop3.password">wso2qa123</parameter>
   <parameter name="mail.pop3.port">995</parameter>
   <parameter name="mail.pop3.socketFactory.fallback">false</parameter>
   <description/>
</proxy>

3. Now Send a Email to your Email account and you will see the following log in backlogs.

[2016-08-03 12:10:05,232]  INFO - LogMediator Date = Wed, 3 Aug 2016 12:09:25 +0530, Subject = This is a Test, Content-Type = multipart/alternative; boundary=001a11402208fef0bb0539251978, From = Yasassri Ratnayake <ycrnet@gmail.com>

So thats it. If you cannot get this to work you can enable Debug logs and check whats wrong. To do this add the following line to repository/conf/log4j.properties and restart the ESB server.

log4j.logger.org.apache.axis2.transport.mail.MailTransportListener=DEBUG
