Read Mails using JMeter Mail Reader Sampler

JMeter provides various options to handle email related scenarios in load testing activities. We already saw how we can send an email using JMeter in earlier post. This post now covers JMeter Mail Reader Sampler which can be used to receive emails from JMeter. This mail reading feature helps in number of scenarios like email verification, email confirmation etc.
We will use Mail Reader Sampler of JMeter to read 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 JMeter Mail Reader Sampler.
  • Add a new Thread Group under Test Plan.
  • Right click on Thread Group and select Add–>Sampler–>Mail Reader Sampler. Once added, we need to provide IMAP/POP3 server details in sampler.
  • We will use GMail’s IMAP protocol for receiving an email in JMeter. Therefore, set Protocol value to ‘imaps’. Similarly enter ‘imap.googlemail.com’ and ‘993’ as server host and port values respectively.
  • Provide valid user name and password values.
  • We can also specify number mails we want to receive.
  • As GMail requires SSL, select ‘Use SSL’ radio button in Security Settings section.
  • After performing all above steps, your Mail Reader Sampler should be displayed as below image.

  • Run your test!
Below are other notable options present in Mail Reader Sampler.
  • Folder – a folder in email account.
  • Delete messages from the server – specify whether JMeter should remove messages from the server after retrieval.
  • Store the message using MIME – specify whether the entire message will be stored in the Response Data.
After performing above simple steps, you should be able to configure your JMeter to read emails. To view the result, add a ‘View Result Tree’ listener under the Thread Group where you could read your emails.

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...

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...

SSO with SAML login scenario in JMeter

SAML(Security Assertion Markup Language) is increasingly being used to perform single sign-on(SSO) operations. As WikiPedia puts it, SAML is an XML-based open standard data format for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. With the rise in use of SAML in web applications, we may need to handle this in JMeter. This step-by-step tutorial shows SAML JMeter scenario to perform login operation. First request from JMeter is a GET request to fetch Login page. We need to fetch two values ‘SAMLRequest’ and ‘RelayState’ from the Login page response data. We can do this by using  Regular Expression Extractor . These two values need to be sent in POST request to service provider. Refer below image to see how to do this. We will get an HTML login page as a response to the request sent in 1st step. We need to fetch values of some hidden elements to pass it in the next request. We...
