mcbsf / redis_like Goto Github PK

Repository made to simulate a simple redis operation. There are 2 base files:

1. redis_like.py with a class called Redis inside, with limited functionalities.
2. main.py, to generate a user interface via console to manage this Redis class

cd {path_to_proejct}

python3 main.py

As asked by the stakeholders of this repository, the commands via console are limited to:

GET <key>

SET <key><value>

UNSET <key>

NUMEQUALTO <value>

END

BEGIN

COMMIT

ROLLBACK

It's important to ensurue this format, with upper case on function and same whitespaces to work properly. Further upgrades can be done to turn into user friendly console.

SET <a1><123>

NUMEQUALTO <a1>

GET <a1>

END

• get(key)

• set(key, value)

• unset(key)

• num_equal_to(key)

• begin()

• commit()

• rollback()

Unit tests could be done using pytest tool, executing isolated Redis class functions with valid inputs to ensure the expected outputs.

Chain of calls could be done on differents Redis class functions to ensure data flow, could be used pytest also

A robot could be built to test the console interface main.py, testing invalid and valid inputs to ensure the file works properly. could be used PyUserInput to simulate those events, since needs a console handler. If was web app, Selenium webdrive could be used. I have a repository with this tool to create a robot to play a game, the repository is "aow_auto_clicker", go check it out!

• considering that wont have any '<' or '>' in paramter value, just as param delimiter
• considering all inputs will be user input raw data, as string

for redis storage I choose dict as storage type, becouse:

• No persistence needed

• Almost instantaneous transactions(insert/delete/update)

• Almost instantaneous access by keys

Due to the simplicity of the implementation and lack of development time, exceptions threatment wasn't made. User input is already being validated with regex pattern, what will ensure it's usability via console
