Api testing via postman and automating via python

# tutorial: api testing with postman and automating with python

## introduction
api testing is an important part of software testing to ensure that apis work as expected. postman is a popular tool for api testing due to its user-friendly interface and features. automating api testing with python can streamline the testing process, especially for repetitive tasks.

in this tutorial, we will cover how to perform api testing using postman and then automate the testing process using python.

### prerequisites
3. install the `requests` library: you can install the `requests` library using pip by running `pip install requests`.

## steps

### step 1: api testing with postman
1. open postman and create a new request by entering the api endpoint url.
2. add any required headers, parameters, or authentication details.
3. send the request and verify the response received.
4. validate the response data, status code, headers, etc.
5. save the request in a postman collection for future reference.

### step 2: export postman collection
1. in postman, go to the collections tab and right-click on the collection.
2. select "export" and choose the format as "collection v2.1" to export the collection as a json file.

### step 3: automating api testing with python
1. create a python script to automate api testing using the `requests` library.
2. load the postman collection json file and extract the request details.
3. send api requests using the extracted details and validate the responses.
4. implement test cases and assertions to verify the api responses.
5. run the python script to automate the api testing process.
