Useful for build systems that understand Junit. +Because of the way the junit format is structured the run must complete before anything is written. +* `xml` writes an xml format tailored to Catch. Unlike `junit` this is a streaming format so results are delivered progressively. + +There are a few additional reporters, for specific build systems, in the Catch repository (in `include\reporters`) which you can `#include` in your project if you would like to make use of them. +Do this in one source file - typically the same one you have `CATCH_CONFIG_MAIN` or `CATCH_CONFIG_RUNNER`. + +* `teamcity` writes the native, streaming, format that [TeamCity](https://www.jetbrains.com/teamcity/) understands. +Use this when building as part of a TeamCity build to see results as they happen. +* `tap` writes in the TAP ([Test Anything Protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol)) format. +* `automake` writes in a format that correspond to [automake .trs](https://www.gnu.org/software/automake/manual/html_node/Log-files-generation-and-test-results-recording.html) files + +You see what reporters are available from the command line by running with `--list-reporters`. + +By default all these reports are written to stdout, but can be redirected to a file with [`-o` or `--out`](command-line.md#sending-output-to-a-file) + +## Writing your own reporter + +You can write your own custom reporter and register it with Catch. +At time of writing the interface is subject to some changes so is not, yet, documented here. +If you are determined you shouldn't have too much trouble working it out from the existing implementations - +but do keep in mind upcoming changes (these will be minor, simplifying, changes such as not needing to forward calls to the base class). + +--- + +[Home](Readme.md) \ No newline at end of file
