Control tree diagram branches

I have the following tree:

\begin{center}\begin{forest}[Tests  [Case 1    [\text{OGL1}]    [\text{OGL2}]    [\text{OGL3}]    [\text{OGL4}]      ]  [Case 2    [\text{OGL1}]    [\text{OGL2}]    [\text{OGL3}]    [\text{OGL4}]   ]  [Case 3    [\text{OGL1}]    [\text{OGL2}]    [\text{OGL3}]    [\text{OGL4}]   ]  [Case 4    [\text{OGL1}]    [\text{OGL2}]    [\text{OGL3}]    [\text{OGL4}]   ]]      \end{forest}\end{center}

However, the tree is too wide and goes out of the paper.

Is there a nice way to make it fit in the paper without having letters on each other?

If there a different type of tree that can solve it, it also will be nice to know.

Thank you!
