This is a quick tutorial on how to test code using the GoMock mocking library and the standard library testing package testing.
GoMock is a mock framework for Go. It enjoys a somewhat official status as part of the github.com/golang organization, integrates well with the built-in testing package, and provides a flexible expectation API.

Go provides file-opening flags represented by constants defined in the os package. These flags determine the behavior of file operations, such as opening, creating, and truncating files. The following is a list of the flags and what they do.
os.O_RDONLY: Opens the file as read-only. The file must exist.
os.O_WRONLY: Opens the file as write-only. If the file exists, its contents are truncated. If it doesn't exist, a new file is created.
os.O_RDWR: Opens the file for reading and writing. If the file exists, its contents are truncated. If it doesn't exist, a new file is created.
