How to run the app?

Prerequisite

Use the Windows or Mac with dotnet 5.0 installed: https://dotnet.microsoft.com/download

Download and Run

• Clone the repository: git clone git@github.com:shishirajm/UserLookup.git
• Navigate to UserLookup: cd UserLookup
• Run dotnet test: dotnet test
• Run the Console Project and follow prompts: dotnet run -p ./src/UserLookup.Console

Decisions:

Assumptions

• Current payload structure of repeated Id is valid.
• All Gender values are considered valid.

Coding decisions

• Though Ids are repeated (which is usually not the case) in JSON, nothing is discarded. Search by Id returns the first one.
• Gender with M and F are considered Male and Female respectively. Gender without M or F not accounted for either Male or Female.
• Caching implementation is fundamental, and it caches the whole API response. Based on how things would grow, the caching can be tuned.
• For Console display haven't spent much time. It might feel basic.
• More validations can be added after the API records are read.
• There is a scope for adding hundreds of unit tests. In the interest of time, its skipped. Added a few sample tests.
