Review Summary

Your solution is approved. All core functional requirements for the fillTank function are properly tested and passing: function declaration, return value verification, customer object structure, full tank filling, tank capacity constraints, affordability limits, minimum 2-liter threshold, and rounding behavior to the tenth part. The review identified only minor gaps in test coverage - specifically that price rounding to the nearest hundredth is not explicitly tested with a fractional price value (tests use fuelPrice = 10 instead of a value like 10.567). This is a supplementary testing enhancement rather than a critical blocker, since the core functionality is validated and all tests pass without failures. Your implementation demonstrates solid understanding of Jest testing patterns, proper use of beforeEach for test setup, and thorough edge case coverage. Consider adding a test with fractional pricing in the future to increase test robustness, but this is not required for approval.
