A Tutorial to Send Email using JMeter

Sending email is a mundane activity in any professional’s life. It’s a common medium for communication nowadays. Therefore performance testing of email server is not only important but necessary for an organization. JMeter can be helpful to perform load testing in such scenarios. In this tutorial, we will see how JMeter can be used to send email.
We will use SMTP Sampler of JMeter to send an email. JavaMail API is needed to enable email functionality in JMeter. Download it from here and paste the jar in JMeter’s lib folder. Now, perform below steps to configure SMTP Sampler.
  • Add a new Thread Group under Test Plan.
  • Right click on Thread Group and select Add–>Sampler–>SMTP Sampler. We need to populate SMTP server’s details in this sampler.
  • We will use GMail for sending an email. For this, enter these values in SMTP Sampler fields. Server: smtp.googlemail.com, Port: 587.
  • Provide values in Email Address From and To fields of Mail Settings section to specify sender and recipient.
  • Check ‘Use Auth’ checkbox and provide authentication details.
  • Select ‘Use StartTLS’ option as GMail’s SMTP server requires that security setting.
  • Provide values for email Subject and Content in Message Settings section. You can also attach an attachment from there.
  • After performing all above steps, your SMTP Sampler should be displayed as below image.

  • Run your test!
After performing above steps you should be able to send email using JMeter. Oh and in case you want to know how we can receive a mail using JMeter, read it here. We hope the above examples does a good job to explain you the JMeter mail sending. In case you are stuck at some point or you know any better way to handle emails in JMeter, do let us know about it in comments.

JMeter Exceeded Maximum Number of Redirects Error Solution

While running performance test, JMeter allows maximum 5 redirects by default. However, if your system demands more than 5 redirects, it may result in JMeter exceeded maximum number of redirects error. In this post, we have listed down steps to overcome this error. Actual error in JMeter: Response code: “Non HTTP response code: java.io.IOException” Response message: “Non HTTP response message: Exceeded maximum number of redirects: 5” This error is noticed because  JMeter  allows maximum 5 redirects by default and your system may be using more than 5 redirects. You need to increase this count to more than 5 in jmeter.properties file. Follow below steps to achieve this. Navigate to /bin directory of your JMeter installation. Locate jmeter.properties file and open it in any editor. Search for “httpsampler.max_redirects” property in opened file. Uncomment the above property by removing # before it. Change to value to more than 5 Eg. 20. Save the file and restart JMet...

Performance Testing in the Cloud with JMeter & AWS

JMeter is a wonderful tool  to stress test your website and  your application architecture , however if you are trying to simulate many users (>1000) one JMeter instance (=pc) will not be sufficient. You will have to set up a JMeter cluster with multiple machines. JMeter is capable or running  distributed tests , but it comes with limitations. Since most of us don’t have multiple servers laying around somewhere, we usually go to cloud service providers like  AWS , spin up a couple of  EC2 instances  and turn them off whenever we’re done. Here is the problem, JMeter uses  Java RMI (Remote Method Invocation)  to communicate to its slaves, but these connections require all machines to be on the same subnet and this is not feasible with EC2 instances. Below, I explain how to get around this problem using a 3 node configuration in AWS to execute tests. I assume that you have a written the test already and have the .jmx file r...

Difference Between Redirect Automatically and Follow Redirects in JMeter

In this post, we will highlight important difference between Redirect Automatically and Follow Redirects options. These options are found in HTTP Request sampler of JMeter. Knowing the difference will help you decide your performance test strategy. When you check Redirect Automatically option, JMeter will not consider redirect as separate HTTP request. This in turn may result as lower response time in your overall performance test. Whereas Follow Redirect option will consider each redirection as separate requests. This may result in comparatively higher response time. This only has any effect if “Redirect Automatically” is not enabled. To see the difference between these two, record a sample script and run it by checking Redirect Automatically and Follow Redirects option. The second option will generate more requests in your result listener. As you can see from the above post, knowing the difference between Redirect Automatically and Follow Redirects option makes difference i...
