NAME

Test::JavaScript - JavaScript Testing Module

SYNOPSIS

use Test::JavaScript qw(no_plan);

js_eval_ok("/path/to/MyFile.js");

js_ok("var obj = new MyFile", "Create a MyFile object");

js_ok("obj.someFunction = function () { return 'ok' }");

js_is("obj.someFunction()", "ok");

DESCRIPTION

Test::JavaScript provides a method of unit testing javascript code from within perl. This module uses the JavaScript::SpiderMonkey package to evaluate JavaScript using the SpiderMonkey JavaScript engine.

js_eval_ok

js_eval_ok($filename)

This reads a file and evals it in JavaScript

For example:

js_eval_ok( "/path/to/some/file.js" );

js_is

js_isnt

js_is  ( $this, $that, $test_name );
js_isnt( $this, $that, $test_name );

This compares two values in JavaScript land. They can be literal strings passed from perl or variables defined earlier.

For example:

js_ok("var i = 3");					// ok
js_is("i", 3, "i is 3");				// ok
js_is("3", 3, "3 is 3");				// ok
js_is("3", 2, "3 is 2");				// not ok

js_ok("function three () { return 3 }");		// ok
js_is("three()", 3);				// ok
js_is("three()", 4);				// not ok

js_isnt("3", 4, "3 is not 4");			// ok

js_ok

js_ok("var monkey = 3", $test_name);

The expression passed as the first parameter is evaluated as either true or false. The test fails if the expression explicitly returns false, or if a syntax error occurs in JavaScript land

For example:

js_ok("var i = 3");					    // ok
js_ok("true", "true is true");			    // ok
js_ok("1 == 2", "1 is equal to 2");			    // not ok
js_ok("false", "false is false");			    // not ok
js_ok("var array = ['one','two',non_existing_var];")    // not ok

diag

js_ok("var myval = 3; diag('the variable myval is ' + myval)");

This subroutine simply logs the parameters passed as a comment
