feat: add tests

[julio4]

Most of the current listings do not have tests. Adding tests would ensure that we have not left any logic errors that could confuse readers later on.

We need to add atleast simple integration tests for all contracts. Unit tests can be added for more complex contracts.

• Integration tests are tests that deploy the contract and interact with it's provided interface. They should be placed on a separate file/module tests.cairo.

• Unit tests do not have to deploy the contract and use the interface. Unit tests can use mocked implementation or state to test only one specific feature. They should be placed on the same file as the example (and hidden in the book using ANCHOR).

You do not have to add tests to all missing listings at once.

See this as a reference.

Please open a PR per example.

@petersdt @NueloSE @CollinsC1O Thank you for your interest.
Currently, all chapter0 examples are tested. You can pick any listings without tests and list it here to be assigned to it.
You can take a look at #179 #181 #182 as examples.

You need to specify the 1-3 tests you want to work on it. Only complete tests will be accepted!

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

Hi my name is Jeremiah Samuel. I am a frontend and blockchain developer. I build web solutions and interested in building blockchain infrastructures. I am hardworking and focused

This is my first application for contributing and would be looking forward to be granted that opportunity to gain more experience.

How I plan on tackling this issue

To begin, I would await briefing on the contracts in need of unit testing. After that I would proceed to write the test, submit and wait for your review and feedback which would determine the next course of action. Your feedback is my quality assurance guiding me in the rest of the tests.

@livinalt @EmmanuelAR and others... No need to apply on OnlyDust platform. Just explore listings and find one that have no tests, and implement tests for atleast the most important use cases.

[livinalt]

Thanks for the heads up @julio4. I'll check out the listings
