Description

I'm new to cryptography and want to use PIR to do some experiments, but I can't find a tutorial on how to use this library.

Type of Test

• Unit test (e.g. checking a loop, method, or function is working as intended)
• Integration test (e.g. checking if a certain group or set of functionality is working as intended)
• Regression test (e.g. checking if by adding or removing a module of code allows other systems to continue to function as intended)
• Stress test (e.g. checking to see how well a system performs under various situations, including heavy usage)
• Performance test (e.g. checking to see how efficient a system is as performing the intended task)
• Other...

Expected Behavior

A clear and concise description of what you expected to happen. Do you intend to reach a certain percentage of test coverage for this file, feature, or codebase?
