CoronaSafe Engineering Fellowship Test Problem

The task is performed and the terminal output is as shown:

  1. Install Python: Python is usually installed by default on most modern systems. To check what your currently have, open a terminal and run the following command:

    python3 --version
    

    This should output some information on the installed Python version. You can also install ruby by following these instructions: https://installpython3.com/

  2. execute the todo app by running the following command from the terminal.

    On Windows:

    .\todo.bat
    

    On *nix:

    ./todo.sh
    

Run Automated Tests

1. Install Node.js

You need to have npm installed in your computer for this problem. It comes with Node.js and you can get it by installing Node from https://nodejs.org/en/

2. Install dependencies

Run npm install to install all dependencies.

3. Create Create symbolic link to the executable file

On Windows

To create a symbolic link on Windows, you'll need to run either the Windows Command Prompt, or Windows Powershell with administrator privileges. To do so, right-click on the icon for Command Prompt, or Powershell, and choose the "Run as Administrator" option.

Command Prompt:

> mklink todo todo.bat

Powershell:

> cmd /c mklink todo todo.bat

On *nix:

Run the following command in your shell:

$ ln -s todo.sh todo

4. Try running tests.

Now run npm test and you will see all the tests failing. As you fill in each functionality, you can re-run the tests to see them passing one by one.

A Note about / for Windows Users

In the following sections, you'll see many commands prefixed with ./, or paths containing the / (forward-slash) character.

If you're using the Windows Command Prompt, then you'll need to replace / with \ (back-slash) for these commands and paths to work as expected.

On Windows Powershell, these substitutions are not required.

Specification

  1. The app can be run in the console with ./todo.

  2. The app should read from and write to a todo.txt text file. Each todo item occupies a single line in this file. Here is an example file that has 2 todo items.

water the plants
change light bulb
  1. When a todo item is completed, it should be removed from todo.txt and instead added to the done.txt text file. This file has a different format:

    x 2020-06-12 the text contents of the todo item
    1. the letter x
    2. the current date in yyyy-mm-dd format
    3. the original text

    The date when the todo is marked as completed is recorded in the yyyy-mm-dd format (ISO 8601). For example, a date like 15th August, 2020 is represented as 2020-08-15.

  2. The application must open the files todo.txt and done.txt from where the app is run, and not where the app is located. For example, if we invoke the app like this:

    $ cd /path/to/plans
    $ /path/to/apps/todo ls
    

    The application should look for the text files in /path/to/plans, since that is the user’s current directory.

Usage

1. Help

Executing the command without any arguments, or with a single argument help prints the CLI usage.

$ ./todo help
Usage :-
$ ./todo add "todo item"  # Add a new todo
$ ./todo ls               # Show remaining todos
$ ./todo del NUMBER       # Delete a todo
$ ./todo done NUMBER      # Complete a todo
$ ./todo help             # Show usage
$ ./todo report           # Statistics

2. List all pending todos

Use the ls command to see all the todos that are not yet complete. The most recently added todo should be displayed first.

$ ./todo ls
[2] change light bulb
[1] water the plants

3. Add a new todo

Use the add command. The text of the todo item should be enclosed within double quotes (otherwise only the first word is considered as the todo text, and the remaining words are treated as different arguments).

$ ./todo add "the thing i need to do"
Added todo: "the thing i need to do"

4. Delete a todo item

Use the del command to remove a todo item by its number.

$ ./todo del 3
Deleted todo #3

Attempting to delete a non-existent todo item should display an error message.

$ ./todo del 5
Error: todo #5 does not exist. Nothing deleted.

5. Mark a todo item as completed

Use the done command to mark a todo item as completed by its number.

$ ./todo done 1
Marked todo #1 as done.

Attempting to mark a non-existed todo item as completed will display an error message.

$ ./todo done 5
Error: todo #5 does not exist.

6. Generate a report

Use the report command to see the latest tally of pending and completed todos.

$ ./todo report
dd/mm/yyyy Pending : 1 Completed : 4
