Contributions summary:Sam primarily contributed to improving the test double library's verification process and error messages. They enhanced the output of verification failures to include details of matching calls and optimized warning messages when both stubbing and verifying the same test double. Furthermore, the user added configuration options to stubbing methods that accept callbacks, including delays and deferment. These changes improve the debugging and asynchronous testing capabilities of the library.
