Description

A package (set of scripts) to download files using various network protocols.

Steps to run

All commands may require sudo/admin privileges

1. Python 3 should be installed on the system (the code has been verified on Python 3.6.3)

2. Using command line, navigate to the folder pydownloader(make sure this folder contains the file README.md and folder resourcedownloader)

3. Install/Configure a virtual environment as follows from the command line (this step may be skipped but it may cause dependency issues on the system) (If already configured go to Step 4)

   a. Installation

    -- Windows  : pip install --user virtualenv
    -- Linux    : python3 -m pip install --user virtualenv
   

   b. Configuration (testassignment is the environment name)

    i. Create
        -- Windows  : python -m virtualenv testassignment
        -- Linux    : python3 -m virtualenv testassignment 
    
    ii.  Activate 
        -- Windows  : .\testassignment\Scripts\activate
        -- Linux    :  source testassignment/bin/activate 
   

   c. Install dependencies

    -- Windows  : pip install -r requirements.txt
    -- Linux    : pip install -r requirements.txt 
   

4. Ignore this step if coming from Step 3 else continue to Activate virtual environment (testassignment is the environment name)

   -- Windows  : .\testassignment\Scripts\activate
   -- Linux    :  source testassignment/bin/activate 
   

5. Create a file resourceurls.txt in pydownloader folder, which should contain the links which are to be downloaded. Currently, http, https, ftp, sftp protocols are supported. Each link should be in different lines. Example shown below

   http://speedtest.tele2.net/1MB.zip
   ftp://speedtest.tele2.net/10MB.zip
   sftp://demo-user:demo-user@demo.wftpserver.com:2222/download/manual_en.pdf

6. From command prompt, run the following command

    -- Windows : python run.py -u resourceurls.txt -d <destfolderpath>
    -- Linux   : python3 run.py -u resourceurls.txt -d <destfolderpath>
    
    where destfolderpath is the path of destination folder where files are to be downloaded 
   

7. The execution trace logs are generated in the Folder below

    -- pydownloader/resourcedownloader/Logs 
   

8. In order to execute the testcases run the following command from command prompt. Before this please make sure to activate the virtual environments as shown in Step 3 or Step 4

    -- Windows  : pytest
    -- Linux    : pytest
