Reporter: Manage test reporting

Description Details See Also Examples


The job of a reporter is to aggregate the results from files, tests, and expectations and display them in an informative way. Every testtthat function that runs multiple tests provides a reporter argument which you can use to override the default (which is selected by default_reporter()).


You only need to use this Reporter object directly if you are creating a new reporter. Currently, creating new Reporters is undocumented, so if you want to create your own, you'll need to make sure that you're familiar with R6 and then need read the source code for a few.
