During performance tests, it is important to validate each page is properly generated for each virtual user.

Validating this manually or through other visual mechanisms is close to impossible. Therefore, an automated method is the best tool to achieve this objective.

Text / Image check points are the solution to this problem. During execution, the script adds a text check function to each page. These functions validate the presence of text content items in the application during test execution. This type of validation runs for each virtual user.

How do you perform a text check?

• JMeter: In the case of JMeter, assertions validate the occurrence of content / image in the response for a page request.
  
  • Different types of assertions are available in JMeter:
  • Response assertion
  • Size assertion
  • XML assertion
  • etc.
• Loadrunner: In case of Loadrunner, the web_reg_find() function runs a text check task. This function adds the text content to validate and places it just before the web request (of the page on which the text must appear).
• Silkperformer: Like that of Loadrunner, Silkperformer also has text check functions.
