Load Testing Training

JMeter is one of the most prominent load testing tool in the field of performance testing. JMeter can be used to carry out performance testing not just for web but also web services, database, LDAP, SMTP, POP3 etc. There is tons of JMeter documentation available online, but if you are beginning with JMeter or Load Testing in general then you might be overwhelmed with the amount of information available online. Following JMeter training video tutorial series tries to make it easy to learn JMeter. This JMeter training video tutorial series focuses on most important aspects of JMeter along with code examples for JMeter. Given that technology changes with time so as the JMeter hence following JMeter training series is expanding with time. So what are you waiting for? Hope on to learning JMeter


Before watching JMeter training videos, you may like to read following tutorials on Performance Testing -





JMeter project file used in tutorial projects can be downloaded as raw version and then you can import it in your JMeter test plan. Other JMeter Project Files are also available for download.

JMeter custom graph -
  • Why use Custom Graphs
  • Setup JMeter Plugins
Jmeter plugin download - http://jmeter-plugins.org/downloads/all/#Latest-Stable-Release

Plot custom graph -
  •    Active Threads Over Time
  •    Response Times Over Time
  •    Transactions per Second
  •    Server Hits per Second (aka Hits per second)
  •    Response Times Percentiles

Combine multiple graphs using Composite Graph







Graph Generator Listener -
  • JMeterPlugins-Extras is for Graphs Generator Listener (from JMeterPlugins-ExtrasLibs jar)
  • Graphs Generator Listener generates the following graphs at end of test or previous test - :
   
Active Threads Over Time
Response Times Over Time
Transactions per Second
Server Hits per Seconds
Response Codes per Second
Response Latencies Over Time
Bytes Throughput Over Time
Response Times vs Threads
Transaction Throughput vs Threads
Response Times Distribution
Response Times Percentiles

  • Generate CSV / PNG for current test results
Requires usages of View Results Tree or Graphs Generator Listener     
Not recommended !

  • Generate CSV / PNG for existing/previous test results







JMeter Backend Listener


  • Test Plan deep dive into seleniumtests.com.jmx test plan
  • Enable View Results Tree listener and Run Test
  • Check that data is pushed in influx db > jmeter database - http://localhost:8083/
  • Disable View Results Tree listener and Run Test from command line.
  • Grafana Dashboard
  • Analyze Grafana Dashboard - http://localhost:3000/
  • Edit board and view query
  • Off line Analysis - Once test run is over then update time stamp and view result of past run

You will find following files -
