How do I change the dot to a colon in a theorem environment?

Minimal Working Example:

\documentclass{book}
\usepackage{amsthm}
\newtheorem*{test}{Test}
\begin{document}
\begin{test}
\end{test}
\end{document}

Not a duplicate of Can I change the dot to a colon after Proof in amsthm? since neither answers there work.

You can define a new style:

\documentclass{book}
\usepackage{amsthm}
\newtheoremstyle{colon}%
{}
{}
{\itshape}%bodyfont
{}%indent
{\bfseries}%headfont
{:}%head punctuation
{ }%space after head
{}

\theoremstyle{colon}
\newtheorem*{test}{Test}


\begin{document}


\begin{test}
Blah blah blah.
\end{test}


\end{document}

You can define a new theorem style like this:

\newtheoremstyle{mystyle}% name of the style to be used
  {}% measure of space to leave above the theorem. E.g.: 3pt
  {}% measure of space to leave below the theorem. E.g.: 3pt
  {}% name of font to use in the body of the theorem
  {}% measure of space to indent
  {}% name of head font
  {:}% punctuation between head and body
  { }% space after theorem head; " " = normal interword space
  {\thmname{#1}\thmnumber{ #2}\thmnote{ #3}}

\theoremstyle{mystyle}

Just add this before the first use of \newtheorem.
