Output to both stdout and file

[sebastiantf]

Would be really nice to have an option to print output both to stdout and file, instead of having to choose either one at a time

[cgewecke]

This is supported in the latest release (2.0). The following options combination outputs the report to file (without color) and to terminal (with color)

outputFile: "./myfile...",
forceTerminalOutput: true,
forceTerminalOutputFormat: "terminal"
