API Testing with Python – Manual & Automation using Pytest

Explore a learning plan that guides beginners through basic manual API testing and Python automation with pytest, while allowing intermediate learners to skip to core sections and framework topics.

Explore the basics of APIs, including what an API is, why it’s needed, and how it mediates between applications to fetch and deliver data.

Learn how APIs provide real-time data across airlines and travel sites by acting as a secure interface between clients and providers, with authentication enabling API and web services.

Learn how APIs power live travel apps by observing real-time API calls on Makemytrip during flight searches, including HTTP methods, headers, status codes, and integration with partner API documentation.

Explore a basic api architecture: a client sends requests (get, post, put, delete) to an application server, which authenticates, accesses the database, and returns a response.

Explain how an API is a pre-written code library you call to perform features. Web services are API deployed on servers over the internet, while API can work without internet.

Learn the basics of http as the foundation of web data exchange, compare rest and soap as architectural styles and xml-based protocols for client-server communication.

Explore rest vs soap with funny examples, showing rest as fast and lightweight but less secure, while soap is bulky but more secure, via http as the data carrier.

Differentiate soap and rest: soap uses an envelope with wsdl and strict standards, while rest exposes business logic via uri and json or xml payload.

Explore the basics of URI, URL, and endpoints by examining host, service paths, and query parameters using real examples from Google and Goibibo, clarifying how resources map to endpoints.

Identify path parameters and query parameters in api calls, and distinguish url from uri, while understanding how base urls use slash for resources and question marks for filtering.

Explore the essential http methods for rest api testing, including get, post, put, delete, and patch, and learn how crud operations map to create, read, update, and delete.

Explore real-time API calls in web apps by inspecting network activity, viewing endpoints like search product and get wishlist, and using curl or postman for manual and automated testing.

Discover manual API testing fundamentals, including how to verify API functionality, performance, reliability, and security using tools like Postman, with real-world examples such as get user and get price APIs.

Learn how Postman, a popular API client, enables manual and automation API testing by creating and saving HTTP requests, reading responses, and sharing code snippets.

Download Postman via Chrome extension or standalone app, choose Mac, Windows, or Linux, install and launch Postman, and explore its dashboard and attributes.

Explore free websites for api testing to practice get, post, put, and delete requests, view real responses, and learn with postman, httpbin, dummy rest api, and json formatter.

Learn how to test a get API with postman, build an employee collection, and save and run requests, while exploring get, post, put, patch, and delete methods.

Use the get method to fetch an employee by ID from a dummy rest API with Postman, see 200 success, and introduce basic API testing concepts for automation.

Explore how the post method creates data via a JSON body in API testing, using postman, to create data into the database, with responses like 200 and 201.

Master put method api testing by updating user data with json payloads on dummy REST APIs, including headers and raw json, and verifying 200 responses.

Perform and validate a DELETE request for an employee record using Postman on a dummy REST API, verify status 200 and that the record has been deleted.

Master the patch method for partially updating user data in api testing with postman, using a json body to update user id two and see status 200.

Discover how http response status codes guide api testing by classifying requests into five series: 100 informational, 200 success, 300 redirection, 400 client-side errors, and 500 server-side errors.

Explore HTTP status codes from informational 100s to server errors 5xx, with common codes, meanings, and how they reveal exact API response causes for Python/pytest automation.

Explore common http status codes from 200 ok to 500 server errors, including 301 redirects, 401 unauthorized, 403 forbidden, 404 not found, 405 method not allowed, and 504 gateway timeout.

Learn how api automation tests apis without manual intervention by scripting tests that validate client requests and server responses using Python and pytest.

Learn how API automation enables early API testing before UI, covering health checks, detailed testing, end-to-end functional testing, and contract, security, performance, and load testing.

Explore the fundamentals of rest API, its representational state transfer over http, client–server communication, stateless design, and typical http methods like get, post, put, delete, and patch.

Download the latest Python 3.11 for Mac, Linux, or Windows, run the installer, and verify the installation by typing python --version or python3 --version in the terminal.

Download Python from python.org and run the Windows installer for Python 3.7.5. Add python.exe to the path during installation to automatically set environment variables.

Configure python on windows by locating installation paths and setting the PATH and script variables. Verify python and pip from the command line and run a simple print to confirm.

Download and set up PyCharm community edition for Python development, install, open, and create a new Python project on Mac or Windows.

Learn how pip, Python’s standard package manager, installs and manages external dependencies from PyPI with commands like pip install, pip uninstall, and pip list.

Learn to install and manage Python packages with pip, including pi test and selenium, using commands like pip install, pip list, and pip uninstall, while inspecting dependencies in site packages.

Create a new Python project in PyCharm, configure a virtual environment, and select Python 3.11 as the interpreter. Run hello world to verify the setup, then explore Python basics.

Create a Python file and write your first program, print a value, and note you can code directly without a class, function, or main method, unlike Java.

Master how Python identifiers work: names start with a letter or underscore and cannot start with digits. Use CamelCase for classes and lowercase for identifiers, with leading underscores indicating privacy.

Demonstrates Python concepts such as indentation, end-of-line spaces, printing, input(), and hash-based comments, with simple comparisons to Java print.
