Q&A
What future topics will be covered in relation to pytest and API testing? ๐
Future sessions will cover topics such as parameter passing and fixtures, which are essential for enhancing your API testing capabilities. Additionally, there will be a focus on generating reports to help document your testing process.
What is a '400 bad request' error, and how can I troubleshoot it? โ ๏ธ
A '400 bad request' error typically arises from incorrect URL configurations or headers. The video discusses how to handle this error, emphasizes the importance of passing correct parameters and headers, and hints at upcoming topics on parameter passing and report generation.
What should I do if I encounter errors when running pytest? ๐
If you encounter errors, it often indicates a mistake in your project setup or code. Ensure that your method names start with 'test' so pytest can recognize them. The video highlights the importance of checking for spelling errors in method names to avoid issues during execution.
How do I validate API response status codes in pytest? โ
To validate the status code of an API response, you can use assertion statements in your tests. The video demonstrates how to check for a 200 OK response and print the entire JSON response for verification, helping you ensure the API behaves as expected.
How do I structure a GET request in Python using pytest? ๐
To structure a GET request, you define a base URL and specify the endpoint for the user data you wish to fetch. The video explains how to combine the base URL with a specific path and what to expect in terms of a successful response, typically a 200 OK status.
What are the naming conventions for test cases in pytest? ๐
In pytest, test case names should begin or end with 'test'. This helps pytest recognize and execute the tests properly. The video provides insights on how to structure your test case names effectively.
How do I install pytest for API automation? ๐ฆ
To install pytest, you can use the package manager pip. The video provides step-by-step instructions on how to install pytest, enabling you to set up your environment for API testing effectively.
