In b64linebreaker_test.go, the names of error variables "mockErr" and "mockNewlineErr" have been changed to "errMockDefault" and "errMockNewline" to better clarify their roles. All instances in test cases where these error variables were used have been updated correspondingly.
The commit modifies existing test cases in the TestBase64LineBreaker_WriteAndClose function where it introduces mock writers to better simulate I/O operations. The introduced mock writers are 'mockWriterExcess' and 'mockWriterNewline' which respectively simulate scenarios of data exceeding body length and inclusion of newline.
This update includes a new TestBase64LineBreaker_WriteAndClose function with cases for validating write and close operations in the b64linebreaker module. In addition, a mockWriter is introduced to simulate I/O operations for testing purposes.
Updated the fuzzing tests in the `Base64LineBreaker_Write` function. The change specifically converts integer bytes from decimal to octal. This ensures proper testing of a wider range of input scenarios, increasing the reliability and robustness of the code.
Enhanced testing for the Base64LineBreaker_Write function by adding a fuzz test. This additional fuzz test provides the function with a variety of random byte inputs as a way of uncovering any hidden errors and contributing to more reliable coding.
