We start our Ant script by defining properties for the locations of directories and files
b
relative to where we run the Ant build. Next, we define a
rhinounit
Ant script
C
and its arguments by loading its source from rhinoUnitAnt.js. We call the script
D
with
a
fileset
pointing to our JavaScript unit test source, where we include all files with the
js extension. In the same way that we defined a script for
rhinounit
and ran our tests,
we define a script for
JSL
int
E
to help us detect scripting issues, and we finish by run-
ning this
JSL
int script
F
on our source directory. For more on
JSL
int, please see sec-
tion 13.6, “Checking best practices with
JSL
int.”
RhinoUnit tip
When you invoke the
rhinounit
Ant script, make sure you point the
rhino-
UnitUtilPath
argument to the location of the rhinoUnitUtil.js file, for example:
rhinoUnitUtilPath="${rhinounit.src}/rhinoUnitUtil.js"
This takes care of JavaScript unit testing in the build file; please consult the Rhino-
Unit
14
website for additional documentation. Next, we look at the alternative to
RhinoUnit and browser emulation with JsUnit, a framework that drives a web browser
á la Selenium.
13.4.2
JavaScript testing with JsUnit
JsUnit
15
is a JavaScript unit-testing framework written in JavaScript and in Java. We use
it from Ant to drive a web browser in order to validate the same JavaScript we just
tested in the previous section. JsUnit is similar to Selenium in that it controls a web
browser and the tests run in that browser's JavaScript engine.
