Unexpected-knockout
This module extends the Unexpected assertion library with integration for Knockout.
expect(ko.observable(42), 'to equal', ko.observable(42));
expect(ko.observable(42), 'not to equal', ko.observable(24));
expect(ko.observable(42), 'to be observable');
expect(42, 'not to be observable');
expect(ko.observable(42), 'not to be computed');
expect(ko.computed(function () { return 42 }), 'to be computed');
expect({
foo: ko.observable(42),
bar: ko.observable(42),
baz: 42,
qux: ko.computed(function () {
return 42;
})
}, 'to have properties', {
foo: ko.observable(42),
baz: 42,
qux: ko.computed(function () {
return 42;
})
});
How to use
Node
Install it with NPM or add it to your package.json:
$ npm install knockout unexpected unexpected-knockout
Then:
var expect = require('unexpected').clone();
expect.installPlugin(require('unexpected-knockout'));
Browser
Include the unexpected-knockout.js found at the lib directory of this
repository after unexpected itself:
<!-- Knockout -->
<script src="knockout.js"></script>
<!-- Unexpected -->
<script src="unexpected.js"></script>
<script src="unexpected-knockout.js"></script>
this will expose the expect function under the following namespace:
var expect = weknowhow.expect.clone();
expect.installPlugin(weknowhow.unexpectedKnockout);
RequireJS
Include the library with RequireJS the following way:
define(['unexpected', 'unexpected-knockout'], funtion (unexpected, unexpectedKnockout) {
var expect = unexpected.clone();
expect.installPlugin(unexpectedKnockout);
// Your code
});
