102-112: Consider adding expected error message for conversion error test.While this test correctly validates that conversion from u64::MAX to i64 fails, it would be more specific to include the expected error message in the
should_panicattribute, similar to other tests.#[test] -#[should_panic] +#[should_panic(expected = "out of range integral type conversion attempted")] fn test_extend_by_seconds_conversion_error() {
139-149: Consider adding expected error message for addition overflow test.This test correctly verifies overflow handling during nanosecond addition, but would be more specific with an expected error message in the
should_panicattribute, matching the error from line 34.#[test] -#[should_panic] +#[should_panic(expected = "failed to add current nanos")] fn test_to_nanos_addition_overflow() {

57-61: Good test module structure with proper imports.The test module is well-organized with appropriate imports and use statements, allowing tests to access both the module under test and required external dependencies.
62-73: Comprehensive conversion test.Good implementation of the basic conversion test from
TimestamptoProtoTimestamp. The test verifies both seconds and nanos fields are correctly preserved during conversion.
75-87: Solid happy path test for timestamp extension.This test properly validates that extending a timestamp by seconds works correctly in the normal case, ensuring both the seconds field is incremented and the nanos field remains unchanged.
89-100: Good overflow test with specific error message validation.The test effectively checks that attempting to extend beyond the maximum i64 value triggers the expected error. Using
should_panicwith the expected error message provides strong validation of the error handling logic.
114-125: Effective nanosecond conversion test.This test correctly validates the timestamp to nanoseconds conversion logic, using a well-chosen example that includes both seconds and partial seconds (as nanoseconds).
127-137: Beneficial overflow test for maximum seconds.Good test for verifying that converting a timestamp with maximum seconds to nanoseconds correctly handles the overflow condition.
151-167: Good Header conversion test.This test effectively validates the conversion from a Header with a timestamp to a ProtoTimestamp, ensuring all fields are correctly preserved.
169-178: Well-defined error case test for missing timestamp.Good test for verifying the error handling when attempting to convert a Header without a timestamp. The expected error message validates the specific error condition.
57-179: Excellent test coverage for ProtoTimestamp struct.The test suite provides comprehensive coverage of all the public functionality of the ProtoTimestamp struct, including both happy paths and error cases. The tests verify:
- Conversions from different types
- Timestamp extension logic
- Nanosecond conversion
- Multiple overflow conditions
- Error handling
This robust test coverage will help ensure the reliability of the timestamp handling code.
