Align 2 equations in fraction at `=`

Question

I was trying to answer this question on another stackexchange forum, to say that they could use Latex instead, only to find I can't figure how to do this in Latex myself.

Is it possible to have 2 equations one in the numerator and one in denominator, be aligned at = in each? Here is MWE

\documentclass[12pt]{article}
\usepackage{amsmath}

\begin{document}

$\frac{\text{test} = 0.01}{\text{testing} = 0.01}$
\end{document}

Gives

I'd like these two to be aligned at =. Just like when one uses align* environment, except inside a fraction now.

\documentclass[12pt]{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
\text{test} &= 0.01 \\
\text{testing} &= 0.01
\end{align*}
\end{document}

Update
Thanks for all the answers. Wish I can accept them all. I picked

\[
\begin{aligned}
\text{test}&=0.01 \\
\hline
\text{testing}&=0.01
\end{aligned}
\]

Because it was easiest for me to understand how it works. But all answers are really great.

Answer 1

This is, of course, not a fraction. But it's easy to emulate one.

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\[
\begin{aligned}
\text{test}&=0.01 \\
\hline
\text{testing}&=0.01
\end{aligned}
=
\frac{0.01}{0.01}
\]

\end{document}

The spacing is not exactly the same, though.

Just for fun.

\documentclass{article}
\usepackage{amsmath}
\usepackage{booktabs}

\begin{document}

\[
\setlength{\aboverulesep}{0.14ex}
\setlength{\belowrulesep}{0.22ex}
\begin{aligned}
\addlinespace[0.04ex]
\text{test}&=0.01 \\
\midrule[0.4pt]
\text{testing}&=0.01
\end{aligned}
=
\frac{0.01}{0.01}
\]

\end{document}
