Student API with Flask ‍

This is a basic Flask application that implements a simple Student API. You can use this API to manage student data (CRUD operations: Create, Read, Update, Delete).

Prerequisites:

• Python 3.x (https://www.python.org/downloads/)
• Flask (https://flask.palletsprojects.com/)
• Apidog for testing (https://apidog.com)

Running the Application:

1. Clone or download this repository git clone https://github.com/vjabhi000985/python-flask-api.git
2. Install the required dependencies: pip install flask json
3. Run the Flask application: python student_api.py

This will start the Flask development server, typically running on http://127.0.0.1:5000 by default.

Testing Endpoints:

Test Case 1: Get All Students (GET /students)

• In the Apidog editor, navigate to the GET /students endpoint.
• Click "Send". You should see a response with a JSON array containing all student objects (refer to screenshot.

Test Case 2: Get Student by ID (GET /students/int:roll)

• Navigate to the GET /students/{roll} endpoint (replace {roll} with a valid student ID).
• Click "Send". You should see a response with the details of the specific student if it exists. Otherwise, expect a 404 Not Found error.

Test Case 3: Create a New Student (POST /students)

• Navigate to the POST /students endpoint.
• Click on the "Body" tab and select "JSON".
• Paste the following JSON data into the body, replacing placeholders with desired values:

{
 "name": "John Doe",
 "branch": "Computer Science"
}
# Use code with caution.

• Click "Send". You should receive a status code 201 Created and a Location header pointing to the newly created student's resource URL.

Test Case 4: Update a Student (PUT /students/int:roll)

• Navigate to the PUT /students/{roll} endpoint (replace {roll} with a valid student ID).
• In the Body tab, provide updated student information in JSON format (e.g., update the name).
• Click "Send". You should receive a status code 200 OK and the updated student data in the response.

Test Case 5: Delete a Student (DELETE /students/int:roll)

• Navigate to the DELETE /students/{roll} endpoint (replace {roll} with a valid student ID).
• Click "Send". You should receive a status code 200 OK with the deleted student's information in the response (optional, depending on your implementation).
