JMeter Element

• Thread Group: Test User
  • Thread group elements are the beginning points of any test plan. All controllers and samplers must be under a thread group. 
• Samplers: Type of Request
  • Samplers tell JMeter to send requests to a server and wait for a response.
• Listeners: Report
  • Listeners provide access to the information JMeter gathers about the test cases while JMeter runs.
  • The Graph Results listener plots the response times on a graph.
