  53. 53. Preparing for Load Testing 53www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  Need to address a number of concerns with regards to the target server under test.  A load testing helps to benchmark performance behavior of a server, it is important to be able to identify the general expectations and other matters that would normally be taken into account in order to carry out a successful load testing.
  54. 54. Need to Know 54www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  A suitable time to load-test the application, for instance when no development work is taking place on the server and/or no other users are accessing the server.  The performance metrics, accepted levels, or SLAs and goals.  Objectives of the test.  The Internet protocol(s) the application is (are) using (HTTPS, HTTP, FTP, etc.)  If your application has a state, the method used to manage it (URL rewriting, cookies, etc.)  The workload at normal time and at peak time.
  55. 55. Some Helpful Tips to Get Better Results 55www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  Use meaningful test scenarios to construct 'real-life' test cases.  Run JMeter on a machine other than that running the application.  The machine running JMeter should have sufficient network bandwidth, memory, CPU to generate load.  Let JMeter Test Plan run for long time periods, hours or days, or for a large number of iterations.  Ensure that the application is stable and optimized for one user before testing it for concurrent users.  Incorporate 'thinking time' or delays using Timers in your JMeter Test Plan.  Keep a close watch on the four main things: processor, memory, disk, and network.
  56. 56. Using Jmeter Components 56www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  We will test five key scenarios:-  Homepage  Login  Search Item  Select Item  Checkout These scenarios will be included in a single JMeter Test Plan, for simplicity reasons.
  57. 57.

  64. 64. Chapter 6 64www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts Handling the dynamic server values
  65. 65. What’s Inside 65www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts 6.1 - What is Correlation 6.2 - Regular Expression 6.3 – Meta Characters for RegEx 6.4 - Managing session with Regular Expression Extractor 6.5 - Managing sessions with cookies 6.6 - Managing sessions with URL rewriting
  66. 66. What is Correlation 66www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  A Correlation is a Connection or Association.  Capturing the dynamic data that is being generated by the server is called correlation.  Correlation will be done using the Regular Expression Extractor in Jmeter. Reason to Correlation: To overcome script fail we need a way which can capture these dynamically generated session values and pass it subsequently to any part of the script, wherever required. This method to identify and set the dynamic generated value is known as correlation.
  67. 67. Regular Expression 67www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  Extract single string o Suppose you want to match the following portion of a web-page: o name="file" value="readme.txt"> o And you want to extract readme.txt . o A suitable regular expression would be: o name="file" value="(.+?)"> o The special characters above are: o ( and ) - enclose the portion of the match string to be returned o . - match any character o + - one or more times o ? - don't be greedy, i.e. stop when first match succeeds
  68. 68. Meta Characters for RegEx 68www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  Regular expressions use certain characters as meta characters - these characters have a special meaning to the RE engine. Such characters must be escaped by preceding them with (backslash) in order to treat them as ordinary characters.  List of the meta characters and their meaning: Meta Character Definition ( and ) Grouping [ and ] Character classes { and } Repetition *, + and ? Repetition . Wild-Card Character Escape Character | Alternatives ^ and $ Start and End of string or line
  69. 69. Managing session with Regular Expression Extractor 69www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  Name Regular Expression Extractor : jsessionid.  Reference Name : jsessionid  Enter Regular Expression : jsessionid = "(.+?)" /> o (.+?) this refers JMeter captures any values in between LB and RB)  Template : $1$ (this is for grouping)  Match No : 1  Default Value : NONE (To pass default value enter string here)
  70. 70. Managing sessions with cookies 70www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  A majority of web applications rely on cookies to maintain the session state. It's used to store a lot more information, such as user IDs and location preferences.  Start JMeter.  Navigate to Test Plan | Thread Group | Recording Controller  Add Test Script Recorder to Workbench.  In the browser, go to http://demo-old-ofbiz.apache.org/ecommerce/.  Click on Login tab.  Enter admin in the Username field & ofbiz in the Password field.  Click on Login & Logout.  Add Cookie Manager from Config Element.  Save the test plan.
  71. 71. Managing sessions with URL rewriting 71www.jmeter4u.com | Email: jmeter4u@gmail.com | Skype: jmeter.experts  When session ID is attached to all URLs then technique used known as URL rewriting.  This ensures that the session ID is automatically sent back to the server as part of the request, without the need of putting it in the header.  The advantage of this technique is that it works even if a client browser has cookies disabled.  Start JMeter.  Navigate to Test Plan | Thread Group | Recording Controller  Add Test Script Recorder to Workbench.  In the browser, go to http://demo-old-ofbiz.apache.org/ecommerce/.  Click on Login tab.  Enter admin in the Username field & ofbiz in the Password field.  Click on Login & Logout.  Add “HTTP URL Re-writing Modifier” and check ‘Path Extension’ & ‘Cache Session Id’.  Clean up test plan is the already existing session IDs that were captured during our recording.  Save the test plan.
