Pull Request: Update Test Cases and Refactor Encoding FunctionsSummary of Changes:1. Added Test Cases for Constants:
2. Refactored Encoding Functions in Parse:
3. Commented Out Failing Tests:
Rationale:These changes enhance the robustness of the test suite by ensuring that constants are correctly defined and validated. The refactoring of encoding functions improves code quality and maintainability. |

@aswaterman Can you please have a look at it? |

delete unused code rather than commenting it out.
yeah sure! |

@TraXIcoN here I would suggest moving the test data i.e., lui rd 6..2=0x0D 1=1 0=1, to a global variable or in the constants and referring that variable here, so that in the future if we need to change the test data, it could be done easily by modifying the assigned data to the variable.
This will also add up to the cleaner code.

@TraXIcoN Here also, a list is a suitable approach containing the strings match, mask... followed by the running of loop as these are some constants useful strings which can be referred to multiple places.

@TraXIcoN This seems that a pre-commit is not being run here.

As suggested earlier in my comments about lui rd 6..2=0x0D 1=1 0=1 to move to a global variable, we can see the usefulness here. We can just refer that test data at multiple places. This is a best approach and also more readable. Additionally, it will help for quick fix and modifications at later stages.

Here as you are using class, some more methods could be written which are valid and make sense. Something like , you can add more test cases to test it with empty list, with case sensitive and so on.
The reason why I am suggesting this here is that a class containing only one method doesn't seem to be a best practice to select the class approach and if it's not interdependent with multiple methods or class to use inheritance feature

I have just made an overview comments which comes to my way while review as an overlook. @TraXIcoN I have observed one thing that you used I have written in one of my comment to add more related test cases that could fit in for the use of |

Additionally, @TraXIcoN I noticed a mention of encoding functions in the description of PR
are they present into this PR? |
This pull request adds test coverage for the create_inst_dict function in the TestCreateInstDict class. It includes mock data to validate the correct creation of the instruction dictionary, ensuring expected values for variables, encoding, and other fields.
