/**
 * Beside filters there are also so called "tests" available. Tests can be used to test a variable against a common expression. To test a variable or expression you add is plus the name of the test after the variable. For example to find
 * out if a variable is defined you can do name is defined which will then return true or false depending on if name is defined.
 *
 * Tests can accept arguments too. If the test only takes one argument you can leave out the parentheses to group them. For example the following two expressions do the same:
 *
 * {% if loop.index is divisibleby 3 %} {% if loop.index is divisibleby(3) %}
