Jinja style tests were added in https://github.com/mozilla/nunjucks/pull/1033 but it looks like they're only supported with parentheses. This is inconsistent with Jinja, which says:

Tests can accept arguments, too. If the test only takes one argument, you can leave out the parentheses.

Not working:

if x is equalto 1

Working:

if x is equalto(1)

This is not an issue for tests with no args, which work fine:

if x is defined
