Project practice! Teach you JMeter performance test hand in hand

Today's share ： How to use jmeter Perform performance testing , Take a specific project as an example to explain .

One 、 Directory structure
explain ： Confirm that the input parameters of the transfer interface depend on ： Foreground login interface and access submitToken Interface

Two 、 In the directory structure ： Divestment projects --- test plan

The content is shown in the figure above

3、 ... and 、 In the directory structure ： Confirmation of divestment --- Thread group

The content is shown in the figure below ：

Four 、 In the directory structure ： User parameters      Fill in the login user name and password

The content is shown in the figure below ：

5、 ... and 、 In the directory structure ：BeanShellPreProcessor--- Preprocessor

The content is shown in the figure below ：

java The code is ：【 Use base64 Encrypt the user name and password 】

import org.apache.commons.codec.binary.Base64;
String username = vars.get("username");
String password = vars.get("password");
String combineduserpass = username + ":" + password;
byte[] encodedUsernamePassword = Base64.encodeBase64(combineduserpass.getBytes());
vars.put("auth",new String(encodedUsernamePassword));

remarks ：
username--- In the user parameter ： name
password---- In the user parameter ： name

6、 ... and 、 In the directory structure ：HTTP Header Manager

The content is shown in the figure below ：

remarks ：HTTP The name in the header manager is equivalent to python file headers Contents of Li

7、 ... and 、 In the directory structure ：HTTP request — Foreground login interface
The content is shown in the figure below ：

remarks ：
Body Data Content ：{"authorization": "Basic ${auth}"}    This content is the input parameter of the login interface
Parameters auth yes BeanShellPreProcessor【 In the preprocessor ：java The parameters returned by the code ：auth】

8、 ... and 、 In the directory structure ：HTTP request — Foreground login interface     Look at the fruit tree
The content is shown in the figure below ：

Nine 、 In the directory structure ：HTTP request — Foreground login interface    Sign in xAuthToken extract
The content is shown in the figure below ：

Regular expression extractor ： Get the information returned by the login interface ：xAuthToken value

remarks ：
1、 The reference name can be taken arbitrarily , But the name in the regular expression must match the name returned by the interface xAuthToken Keep the same name ;
2、 Generally get the first xAuthToken The value of appearance 【 Templates / Match the Numbers 】;

Ten 、 In the directory structure ：HTTP request — obtain submitToken value
The content is shown in the figure below ：

remarks ：
1、 The interface requests to return submitToken value ;
2、 Input reference such as Body Data Shown ;

11、 ... and 、 In the directory structure ：HTTP request — obtain submitToken value    

submitToken extract 【 Regular expression extractor 】
The content is shown in the figure below ：

remarks ：
1、 Regular expression extractor , Reference names can be freely named , This name will be referenced later ;
2、 The name in the regular expression is ： obtain submitToken Interface returned submitToken The name of the value of ;
3、 Generally, the first name returned by the interface is ：submitToken The name of the value of , namely ：submitToken;

Twelve 、 In the directory structure ：HTTP request — obtain submitToken value    Look at the fruit tree
The content is shown in the figure below ：

13、 ... and 、 In the directory structure ：HTTP request — Confirm the transfer interface
The content is shown in the figure below ：

remarks ：
1、Body Data In the submitToken Variable is ：submitToken extract     Regular expression extractor ： Quote name    submitToken;
2、 Confirm what is required for the transfer interface headers The information is already in the directory structure of ：HTTP Header Manager ;

fourteen 、 In the directory structure ：HTTP request — Confirm the transfer interface      BeanShellPostProcessor
The content is shown in the figure below ：

 

Code ：prev.setDataEncoding("UTF-8");
solve ： Chinese garbled code in the returned result of the interface ;

15、 ... and 、 In the directory structure ：HTTP request — Confirm the transfer interface     Look at the fruit tree
The content is shown in the figure below ：

sixteen 、 In the directory structure ：HTTP request — Confirm the transfer interface    Response assertion
The content is shown in the figure below ：

The red box is marked with ： Confirm the contents that should be included when the transfer interface returns correctly ;
