An error will be thrown if no file was found. This is the file that will be sent to the Coveralls API. Leave empty if you want to combine many files reports. |
 | `files`                      | _optional_ | Default: all coverage files that could be found. Space-separated list of coverage report files produced by your test suite. Example: `files: coverage/test1.lcov coverage/test2.lcov` |
 | `format`                     | _optional_ | Force coverage report format. If not specified, coveralls will try to detect the format based on file extension and/or content. Possible values: `lcov`, `simplecov`, `cobertura`, `jacoco`, `gcov`, `golang`, `python`. See also [supported coverage report formats list](https://github.com/coverallsapp/coverage-reporter#supported-coverage-report-formats). |
