When SimpleLogger logs to a file or Standard.out it includes timings (these are turned off by default if you are logging to a string as they are inconsistent for testing purposes.)
Here's an example of the output:
[May 20, 2021, 9:44:17 PM ~000002ms] => Sample.methodThatLogs() - IN
[May 20, 2021, 9:44:17 PM ~000047ms] => Sample.innerMethod() - IN
[May 20, 2021, 9:44:17 PM ~000001ms] Variable: i = '0'
[May 20, 2021, 9:44:17 PM ~000000ms] <= Sample.innerMethod() - OUT
The important part here is ~000047ms which represents the number of milliseconds that have passed since the previous line SimpleLogger
logged. This allows an easy way to detect bottlenecks by adding log statements and test improvements.
