Consider adding an assertion to verify that the correct type of error is thrown when a panic is expected. This will enhance the robustness of the test cases.

268-343: Consider enhancing the testTestMustNewU256Lwith more descriptive error messages.
[REFACTOR_SUGGESTion]
Adding more descriptive error messages can help quickly identify the cause of failures, especially in automated testing environments. Consider including the input data in the error messages for easier debugging.
490-513: Add detailed assertions inTestUnwrap.
[REFACTOR_SUGGESTion]
The test could benefit from more detailed assertions that check not just the equality of results but also the integrity and structure of the unwrapped data. This can help catch subtle bugs related to data handling.
403-436: Verify panic conditions inTestMustNewU256LFromBigEndian.Ensure that the panic conditions are triggered for the right reasons and validate the type of errors thrown.
Verification successful
The function
TestMustNewU256LFromBigEndianis defined and used inmod/primitives/pkg/math/u256_test.go. The test cases already check for panic conditions usingrequire.Panics, ensuring that the function correctly handles inputs that should trigger a panic.
- The test case
"invalid input - too long"checks for a panic when the input is too long, which is a valid condition to test for.There are no issues found with the panic conditions in the
TestMustNewU256LFromBigEndianfunction.Scripts executed
