JMeter connection database

First, introduce jar package mysql-connector-java-8.0.11.jar, Put in :\apache-jmeter-5.3\lib\ext Under the table of contents .

1. Create a new configuration component in the thread group ：

 2. Fill in the above configuration elements ： To connect mysql For example

Database URL:  jdbc:mysql://localhost:3306/student_info?charset=utf-8&useSSL=false&serverTimezone=UTC&allowMultiQueries=true

 3. Create a new thread in the thread group JDBC Request Sampler ：

 4. Get the response result of the sampler , Response status code ：

   Add to sampler Post Processors ：beanshell Postprocessor ,

// Get the result information of the return sampler ：

String response = prev.getResponseDataAsString();

// Get and return the sampler status code

String status = prev.getResponseCode();

// Output log information

log.info(response);

log.info(status);

// preservation 、 Take out the object

vars.putObject(" Object name ",Object);  # Save the object

vars.getObject("OBJECT_NAME"); # Take out the object

5. Use regular expressions to extract response result field values

  Check whether the extracted content is correct ： You can add Sampler - Commissioning the samplers （debug-sampler）

5.1 Add... To the thread group BeanShell Sampler

Output the contents of regular expression ：

log.info("msg1:"+"${msg1}");

6. Assertion - Response assertion ：

6.1BeanShell Assertion ：

String message ="${msg1}";

if(!message.equals("success")){

        Failure = true;

        FailureMessage = " Assertion failed ";

}else{

FailureMessage = " Assert success ";

}

In the view result tree, you can view the prompt of assertion failure
