How can I apply the same formatting command to the bibliography heading as for all other section headings?

Question

I have been given a template that applies the same formatting command to all sections. I now added a bibliography and want the title of it to be formatted the same way. What is the simplest way to achieve this?

\documentclass{scrartcl}

\usepackage{xcolor,biblatex}
\addbibresource{\jobname.bib}

\begin{filecontents}{\jobname.bib}
@article{Test,
    author = {Test, A},
    title = {What a test}
}
\end{filecontents}

\newcommand{\headingformatting}[1]{\noindent\fcolorbox{black}{orange}{%
\begin{minipage}{\dimexpr\textwidth-2\fboxrule-2\fboxsep\relax}
#1
\end{minipage}}}

\begin{document}

\headingformatting{\section{Test}}
Here I am citing \cite{Test}

\printbibliography

\end{document}

Please ignore the fact, that my \headingformatting is typographically not appeasing. I just wanted to show how the document looks from a technical point of view.

Answer 1

As mentioned in the comments the best solution to this would be to use KOMA-Script features to make sure that \section is typeset as desired without having to invoke \headingformatting for each \section manually.

Since I don't know how to do that, here is the biblatex workaround that defines a new heading style that also applies \headingformatting for \section.

\documentclass{scrartcl}

\usepackage{xcolor,biblatex}

\defbibheading{myheading}[\refname]{\headingformatting{\section{#1}}}

\newcommand{\headingformatting}[1]{\noindent\fcolorbox{black}{orange}{%
\begin{minipage}{\dimexpr\textwidth-2\fboxrule-2\fboxsep\relax}
#1
\end{minipage}}}

\addbibresource{biblatex-examples.bib}

\begin{document}
\headingformatting{\section{Test}}
Here I am citing \cite{sigfridsson}

\printbibliography[heading=myheading]
\end{document}

The definition shown here is based on \section. If you want an unnumbered style, you can go for something like

\makeatletter
\defbibheading{myheading}[\refname]{%
  \headingformatting{\section*{#1}}%
  \@mkboth{\abx@MakeMarkcase{#1}}{\abx@MakeMarkcase{#1}}}
\makeatother

or

\makeatletter
\defbibheading{myheading}[\refname]{%
  \headingformatting{\section*{#1}}%
  \addcontentsline{toc}{section}{#1}%
  \@mkboth{\abx@MakeMarkcase{#1}}{\abx@MakeMarkcase{#1}}}
\makeatother

Answer 2

This should works.

\documentclass{scrartcl}

\usepackage{xcolor,biblatex}
\addbibresource{\jobname.bib}

\begin{filecontents}{\jobname.bib}
@article{Test,
    author = {Test, A},
    title = {What a test}
}
\end{filecontents}

\newcommand{\headingformatting}[1]{\noindent\fcolorbox{black}{orange}{%
\begin{minipage}{\dimexpr\textwidth-2\fboxrule-2\fboxsep\relax}
#1
\end{minipage}}}

\begin{document}

\headingformatting{\section{Test}}
Here I am citing \cite{Test}

\printbibliography[title=\headingformatting{\refname}]

\end{document}
