Day22 send request and parameterization using JMeter

Use JMeter Send a request

send out Get Request with parameters

stay http Write the corresponding request path in the request , Parameter with kv Format write parameters

stay http Request that the default value be set web The default value of the server

• The default agreement is http
• The default port is 80

send out post request

And send get Request consistent steps , Just change the request type to post

If you need to json Format sending parameters need to be added http The header manager adds... To the manager content-type:application/json, Check right post Use multipart/form-data

Send a file

• File name ： Write a specific path
• Parameter name ： Parameter name in actual case
• MIME type ：multipart/form-data

keep cookie

add to http cookie Manager

JMeter Generation script

• Generate scripts by recording
  • Third party tool recording （badboy etc. ）
  • adopt jmeter Bring your own proxy server for recording
• Manually capture packets and write scripts

Add... Under test plan http proxy server

The port can be set to a port that is not occupied by the machine

Target controller ： Save the recorded script under the thread group

Exclusion mode , Exclude by adding suggestions , Filter out the static resources in the request .（ These resources have no impact on performance ）

Set up a proxy server in the browser , The port number should be the same as jmeter Consistent settings

Start the browser and then operate ,jmeter Will record into script

If you record a script for a local project , Use the set proxy when accessing ip To visit , Otherwise, you cannot record

Jmeter A parameterized

If you need to iterate through a request 10 Time , It is required to send different parameter values for each request

• Jmeter You can use parameterized test operations , Common parameterization methods include user-defined variables and CSV

Use defined variables

How to add ： test plan -> Thread group -> The configuration element -> User defined variables

Operation steps ：

1. Add thread group
2. Add user-defined variables （ Add... In the test plan attributes by configuring components or between ）
3. add to HTTP request
4. Add view result tree

advantage ： All the places that need this value use one variable , Easy to maintain

Inferiority ： Multiple users can only take one value , Multiple values cannot be used by multiple users

Use ${ Parameter name } Call parameters

CSV File parameterization

How to add ： test plan -> Thread group -> The configuration element ->CSV data

Operation steps ：

1. Add thread group
2. Definition CSV file
3. add to CSV Data file settings
4. add to HTTP request
5. Add view result tree

advantage ： Different values can be taken for the same user after multiple cycles , It is suitable for parametric testing with large amount of data , It is a common method in interface testing or performance testing

Three requests log in with three accounts respectively
