Alternative ways to display Scalatest results

I am thinking about setting up an automated acceptance testing suite with Scalatest and output the results into a simple web dashboard (say print each scenario text stacked with check marks or crosses next to them). Is there a built-in functionality I can use for alternative ways to display the ordinary output or would I need to output and parse the logs myself?

Consider creating a custom Reporter:

Trait whose instances collect the results of a running suite of tests and presents those results in some way to the user.

Override apply method to handle test events:

class MyReporter extends Reporter {
  def apply(event: Event): Unit = {
    event match {
      case event: InfoProvided => 
      case event: TestFailed =>
      case ...
      case _ =>
    }
  }
}

Configure SBT to use custom reporter like so via -C argument:

Test / testOptions += Tests.Argument("-C", "example.MyReporter")

Here is a working example scalatest-custom-reporter-example.

I looked through the documentation again after Mario's answer and seems like there is in fact built-in functionality for use cases like mine

Using Reporters
You can use ScalaTest's reporters by specifying the passing the following arguments to ScalaTest:

-f[configs...] <filename> - causes test results to be written to the named file
-u <directory> - causes test results to be written to junit-style xml files in the named directory
-h <directory> [-Y ] - causes test results to be written to HTML files in the named directory, optionally included the specified CSS file
-a <number of files to archive> - causes specified number of old summary and durations files to be archived (in summaries/ and durations/ subdirectories) for dashboard reporter (default is two)
-o[configs...] - causes test results to be written back to sbt, which usually displays it on the standard output
-e[configs...] - causes test results to be written to the standard error
-k <host> <port> - causes test results to be written to socket in the named host and port number, using XML format
-K <host> <port> - causes test results to be written to socket in the named host and port number, using Java object binary format
-C[configs...] <reporterclass> - causes test results to be reported to an instance of the specified fully qualified Reporter class name
