Code demonstration of interface testing using Python

1. Preparation

Before starting interface testing, we need to install related Python libraries. You can use the pip command to install the requests library, which is a commonly used HTTP library for sending HTTP requests and processing responses.

pip install requests

2. Send a GET request

The first step in interface testing is to send an HTTP request and get a response. Here is a sample code for sending a GET request:

import requests
 
url = "/users"
response = (url)
print(response.status_code)  # Print the response status codeprint(())  # Print response content，byJSONFormat analysis

The above code first imports the requests library, then defines a URL, uses the () method to send a GET request, and saves the response in the response variable. Finally, we print the status code and content of the response.

3. Send POST request

In interface testing, we usually need to send a POST request with parameters. Here is a sample code for sending a POST request:

import requests
 
url = "/users"
data = {
    "name": "John",
    "age": 30
}
response = (url, data=data)
 
print(response.status_code)
print(())

In the above code, we use the() method to send a POST request and pass the request parameter through the data parameter. Similarly, we printed the status code and content of the response.

4. Processing response

Interface testing is not just about sending requests, but also requires verification and processing of the response. Here is a sample code for processing the response:

import requests
 
url = "/users"
response = (url)
 
if response.status_code == 200:
    json_data = ()
    for user in json_data:
        print(user["name"])
else:
    print("Request failed")

In the above code, we first determine whether the status code of the response is 200. If so, we parse the response content into JSON format and traversal to print each user's name. If the response status code is not 200, print "Request failed".

5. Use assertions to verify

In interface testing, we usually need to assert verification of the response to ensure that the data returned by the interface is in line with expectations. Here is a sample code for validation using assertions:

import requests
import json
 
url = "/users"
response = (url)
 
expected_data = [
    {"name": "John", "age": 30},
    {"name": "Alice", "age": 25}
]
 
if response.status_code == 200:
    actual_data = ()
    assert actual_data == expected_data, "The data returned by the interface does not match expectations"
else:
    assert False, "Request failed"

In the above code, we first define the expected data expected_data, and then assert verification of the actual_data returned by the interface with the expected data. If the assertion fails, an exception is thrown and an error message is printed.

Conclusion:

Python provides a wealth of libraries and tools to make interface testing simple and efficient. Through the introduction and sample code of this article, I believe readers have learned how to use Python for interface testing. I hope this article will be helpful to everyone in interface testing, improve testing efficiency and ensure software quality.
