Introduction to response assertion components:
The function of the response assertion element is to perform automatic assertion verification on the response information of the interface to determine whether the interface return value obtained by the interface test is correct. This element in jmeter supports comparing various fields of the request or response with the pattern string. With this component, automated interface testing can be completed without the need to manually check the results returned by the interface.

Introduction to response assertion component fields:
Name/Comment:Custom descriptive text
APPly to: action function
Main sample and sub-samples: Sampler acting on the main node and the sampler corresponding to the sub-node
Main sample only:Sample that only acts on the main node
Sub-samples only: Sampler that only acts on sub-nodes
JMeter Variable Name to use: Acts on jmeter variables (the variable name of jmeter can be entered in the input box), extracting the required value from the specified variable value
Test field:The response field selection to be asserted supports request information, response information, etc., where the response text represents text extracted from various types of documents through Apache Tika< /span>
Ignore state:The overall success of the sampler depends on the assertion result combined with the existing response state, which is forced when the "Ignore state" checkbox is selected Success, then perform this assertion evaluation
A request has multiple response assertions. When the first assertion sets this option, then if the first assertion fails and the second assertion succeeds, the transaction will still be in a successful state (the last assertion must be checked)
Pattern matching rules:
1. Includes - true if the text contains a regular expression pattern
2. Match - true if the entire text matches the regular expression pattern
3. Equals - true if the entire text is equal to the pattern string (case sensitive)
4. String (Substring) - true if the text contains the pattern string (case sensitive)
5. No - Invert the check result to indicate that it does not contain, does not match, is not equal to, and does not have a Substring that matches the pattern string.
6. Or - An assertion can add multiple "patterns to be tested". With the OR option, the assertion will succeed as long as one of the patterns matches. If "OR" is not selected, the AND option will be used by default. All patterns must match for the assertion to succeed.
Mode to be tested:Enter the expected result value, you can add multiple rows of expected results
Customized failure message:Set a custom assertion failure message to replace the system's default failure prompt message.
Practical examples:
Response text: Determine whether there is 7200 in the returned body; as shown below
Response code (response status code): Determine whether the response status code is 200; as shown below
Response information: Determine whether the response headers are OK; as shown below
Response header:Determine whether the information in the response headers contains the specified information; as shown below:
Request header: Determine whether the request header contains the specified information; as shown below
URL sample: Determine whether there is specified information in the url; as shown below
