Back-end development skills-use Jmeter to test your interface performance

1. JmeterIntroduction

Apache JMeterIt is a stress testing tool Apachedeveloped by the organization Java. Used for stress testing of software, it was originally designed for Webapplication testing, but later expanded to other testing areas. We can test for interface concurrency issues.

2. Environmental installation

• 1. First make sure jdkthe environment has been installed on your computer

  # 查看版本
  java -version
  

• 2. Download from the official websiteJMETER , pay attention to jdkthe version

  If you are a windowsystem computer, download zipthe package in the following format, macand download the package circled in the figure below

  

• 3. Unzip the file and run the command

  • macAfter the computer is decompressed bin, run the command in the directorysh jmeter
    

  • windowThe system computer can directly click on bin/jmeter.batthe file to start

• 4. Configure Chinese interface
  

Three, simulate and test an interface

• 1. Create a thread group
  

• 2. Basic configuration of thread group
  

• 3. Create a httprequest (similar postmanto initiate a request in)
  

• 4. Configuration request information
  

• 5. Create a listener (similar to httprespond after initiating a request)
  

Fourth, configure the request header

• 1. jsonThe method used to extract the login interfacetoken
  
  

• 2. httpSet the request header in another interface and pass the token
  
  

Five, directly execute sqlstatements to obtain data and test concurrency

• 1. The downloaded mysqlpackage

• 2. Unzip the downloaded file and jarcopy the package inside to the jmeter/bindirectory (easy to find and not accidentally deleted)

• 3. jemeterCreate a thread group in (the same as above)

• 4. Configure the jdbcconnection
  

• 5. Configuration information

  • url:jdbc:mysql://host:port/{dbname}?allowMultiQueries=true&serverTimezone=UTC
  • DriverName:com.mysql.jdbc.Driver
    

• 6. Create oneJDBC Request
  
  

• 7. Configure the login interface

  • Configure the global default request
    
    

  • Configure login request interface
    

  • Configure the counter ( variables sqlare used in the statement above ${offset})
