Tutorial 16 – GET Request API testing in Playwright Python

Code snippets
Automate API GET Request (status code 200)
Launch https://reqres.in/
Click GET request shown against SINGLE USER.
Notice that the response is 200 (viz the GET request was successfully processed by the server)
Also notice the ‘Request’ uri that is shown above viz /api/users/2.
Let us see how to validate the response status in Playwright.
But before we look into that, open pycharm and go to File > Settings.
The below window comes up. Select ‘Python Interpreter’ as shown below
On the right hand side, you should see ‘requests’ package (as seen above). This is required for API testing.
If you don’t see ‘requests’ package, click + icon (see above snapshot). The below window would come up.
Search for ‘requests’ package and install it
After installing, you should see the ‘requests’ package in the earlier window that we had seen.
We have to import the ‘requests’ package
Now, when you type requests.get you would see one of the parameters as url
Also, when you mouse hover .get, you would see the entire documentation
Our url is composed of ‘base url’ plus ‘uri’
Also, if you again mouse hover ‘get’ method, we see that it returns us the ‘Response’ object
So let us capture the o/p in a ‘resp’ variable
We can now invoke the ‘status_code’ method
Thus we have
Our entire code snippet looks like below
Save and execute
Notice above that the console shows the status code 200
Automate API GET Request (status code 404)
Let us now test below api having response code of 404
Below would be our script
Save and execute.
Notice the console showing status code 404. The code 200 is shown for the previous get request
This is how we test Get APIs.
Refer https://playwright.dev/python/docs/api-testing
Code snippet
import requests
from playwright.sync_api import Playwright, sync_playwright, expect
def run(playwright: Playwright) -> None:
#status code 200
resp = requests.get("https://reqres.in/api/users/2")
print(resp.status_code)
# status code 404
resp = requests.get("https://reqres.in/api/users/23")
print(resp.status_code)
with sync_playwright() as playwright:
run(playwright)
