Why use logs?

Logs can be a good way to capture both flow of a program and state as the program progresses. Adding logs to a program is also extremely safe which allows you to get regression tests in place.

StringBuffer log = SimpleLogger.logToString();
new Sample().methodThatLogs();
Approvals.verify(log);
