1. What is performance automation testing?
Mixer performance
△ System load capacity
△ Stability under overload operation
△ System Bottleneck
Automatic test
Use procedures instead of manual work
Improve test efficiency
◆ Performance automation
Use code to simulate mass users
△ Let users make concurrent requests
△ Multi-page multi-user concurrent request
△ Collection parameters, statistics system load capacity
△ Report generation
2. Performance automated test libraries in Python?
Locust library
Mixer using Python
Use code to create bulk users
In pieces distributed
Distributed performance testing can be performed on multiple servers
△ High scalability
◆ Stable and widely used
▷ Stand the test of various situations
△ Display test details based on web UI interface
△ Can test any system
Two, basic operation
1. Install locust
◆ Use the official PYPI source to install
pip install locustio
◆ Use Douban PYPI source to install (recommended)
pip install -i pypi.douban.com/simple locustio
After the installation is successful, a new command is displayed on the CMD console. You can enter the following command to view the command:
2. Basic usage
Create the locustFile.py file in the project root directory
Perform performance tests
After running, the console listens for a port locally
A. The program file should be named locustfile.py
B. If the name is one_example.py, run this command
locust -f one_example.py
◆ Open the UI setting interface in the browser
△ The default value is localhost:8089
3. Comprehensive case drills
1. Write automated test scripts
◆ Create test_load.py in the root directory of the project
2. Run the command line
◆ Open the Pycharm Terminal console and run the following command:
Note: the –host parameter specifies the HTTP host address, and the -f parameter specifies the pressure program file name
3. Open the Web UI for configuration
Example Set the number of concurrent users to 10 and create a user every five seconds

Four,
◆ LocUST pressure measurement function is extremely powerful
◆ Support distributed deployment
◆ Simple interface
Pressure test code is very easy to write
Provide a UI interface for configuration
Beautiful and detailed chart statistics
