Notes
1. No checking is done that the object in STACK matches one in GeoGebra. If it does not exist it will be created by GeoGebra.
2. Currently setting points and values are the only supported objects. Users can set objects, e.g. you could define `g:x^3` and set this in an appletm

On the question testing page is a "Send to CAS" button. Pressing this sends the question variables and general feedback to a special page which enables more efficient authoring of the feedback in the context of the values of the variables. You still need to copy this by hand into the question edit form when you are satisfied.
A Moodle administrator can run all of the questions tests within a particular course, or across the whole site by following the links on the STACK admin page. It is useful do to this after upgrading the STACK code on the server to identify any test cases which have changed.

Test cases can include a meaningful description of up to 255 characters. This field is a simple string, and is not castext.

\[ f(x) = \left\{ \begin{array}{cc} 1, & x<0 \\ 0, & x\geq 0 \end{array}\right.\]
then you will have to display the matrix without parentheses and sort out the mismatching parentheses in the CASText at the level of display.
For example, if we have the question variable `f:matrix([4*x+4, x<1],[-x^2-4*x-8, x>=1];` and the castext `\[ f(x) := \left\{ {@(lmxchar:"", f)@} \right. \]` the STACK generates

\[ f(x) := \left\{ {\begin{array}{cc} 4\cdot x+4 & x < 1 \\ -x^2-4\cdot x-8 & x\geq 1 \end{array}} \right. \]
Notice the use of LaTeX `\left\{` to automatically size the parentheses and `\right.` to represent a matching, but invisible closing parentesis.
