Basic HTML concepts required for Selenium

What is HTML?
As you know HTML Hyper Text Markup Language used for describing web pages. Each tag represents a document content. HTML contains tags with angle brackets like and plain text. There are two tags one is start tag and second tag is end tag. Every tag should end with a forward slash before the tag name.
Syntax:
<tagname>content here</tagname>
<html>
<head></head>
<body>
<h1>My First H1 Heading</h1>
<p>My first paragraph content goes here</p>
</body>
</html>
HTML tags determine to display the content to display on the web browser. The current version (At the time of writing) of HTML is version 5.
Now coming to our selenium, we generally see the below elements / attributes in any of the simple web page.
  • Text-box
  • Text-area
  • link
  • radio-buttons
  • check-box
  • drop-down / list-box
  • table, Etc....
    • We can divide the elements in three ways:
    1. Single Elements
    2. Group Elements
    3. Customized Elements
    For Single elements, we can easily find out an locator to work with selenium. We can locate by ID or by Link or by Link Text.


    single elements


    For Group elements, we should try to prefer name as identifier along with a combination of value or index property.


    group elements


    In the below screen shot, we can use name as "birthday_month" and value to select the particular month.

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 JMeter. If

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 can do this b

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 reci
