NAME

Test::JavaScript - JavaScript Testing Module

SYNOPSIS

use Test::JavaScript qw(no_plan);

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

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

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

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.

use_ok

use_ok($filename)

This reads a file and evals it in JavaScript

For example:

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

is

isnt

is  ( $this, $that, $test_name );
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:

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

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

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

ok

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:

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