QA:Testcase curl

Description

This test case ensures the correct functioning of curl, which is a command-line tool for transferring data with URL syntax, supporting a range of protocols such as HTTP, HTTPS, FTP, and more.

Setup

1. Install a fresh version of Fedora.
2. Install curl: sudo dnf install curl.

How to test

1. Fetch a basic web page: curl http://example.com.
2. Fetch a web page and follow redirects: curl -L http://example.com.
3. Fetch a web page with verbose output: curl -v http://example.com.
4. Test a secured connection (e.g., HTTPS): curl https://example.com.
5. Attempt to fetch a non-existent URL to test error handling: curl http://nonexistenturl.xyz.

Expected Results

1. The curl command should fetch the content of the example.com homepage without errors.
2. When using the -L flag, curl should follow redirects and display the final page content.
3. The -v flag should provide verbose output, detailing the request and response process.
4. The HTTPS request should be made without SSL errors.
5. For the non-existent URL, curl should display an appropriate error message.

Optional

For extended testing:

1. Use curl to fetch files from an FTP server if available.
2. Test POST and other HTTP methods using curl.
3. Examine manual pages for more commands and options: e.g., man curl.
