Screw.Unit 0.3 is now available. I’m skipping 0.2 since there have been two milestones worth of additions to the new version of Screw.Unit. New features:
- test suite functionality
- afters
- global befores and afters
- enhanced error messages
- new matchers
Here’s how to do a global before:
Screw.Unit(function() {
before(function() {
$("#screw_unit_content").html("");
ActiveAjaxRequests.length = 0;
PainPoint.instances = [];
delete window._token;
});
});
Put this, for instance, in your spec_helper.js file.
Here is how to manage a suite:
Have a suite.html file that requires the Screw.Unit source, your spec helper, and your various test files.
<html>
<head>
<script src="../lib/jquery-1.2.3.js"></script>
<script src="../lib/jquery.fn.js"></script>
<script src="../lib/jquery.print.js"></script>
<script src="../lib/screw.builder.js"></script>
<script src="../lib/screw.matchers.js"></script>
<script src="../lib/screw.events.js"></script>
<script src="../lib/screw.behaviors.js"></script>
<script src="spec_helper.js"></script> <!-- SPEC HELPER -->
<script src="behaviors_spec.js"></script><!-- A SPEC -->
<script src="matchers_spec.js"></script> <!-- ANOTHER SPEC -->
<link rel="stylesheet" href="../lib/screw.css">
</head>
<body></body>
</html>
Have a test file (for example, matchers_spec.js):
Screw.Unit(function() {
var global_before_invoked = false;
before(function() { global_before_invoked = true });
describe('Behaviors', function() {
describe('#run', function() {
describe("a simple [describe]", function() {
it("invokes the global [before] before an [it]", function() {
expect(global_before_invoked).to(equal, true);
});
...
});
Extra Powerful Matchers
// hash equality
expect({a: 'b', c: 'd'}).to(equal, {a: 'b', c: 'd'});
// recursive array equality
expect([{a: 'b'}, {c: 'd'}]).to(equal, [{a: 'b'}, {c: 'd'}]);
// regular expressions and string inclusion
expect("The wheels of the bus").to(match, /bus/);
expect("The wheels of the bus").to(match, "wheels");
// array emptiness:
expect([]).to(be_empty);
expect([1]).to_not(be_empty);
Thanks To
- Brian Takita for the ideas and much of the implementation.
