POUnit Test with Mongoose
text
Body
copied!<p>I'm new to Node.js, Mongoose, and testing in this environment. I have the following schema declared in a separate file. </p> <pre><code>Issue = mongoose.model("Issue", { identifier: String, date: String, url: String, name: String, thumbnailURL: String }); </code></pre> <p>Then I have this method which simply returns all of the <code>Issue</code> instances in the MongoDB collection. </p> <pre><code>function issues(request, response) { response.setHeader('Content-Type', 'text/json'); Issue.find().sort('date').exec(function(error, items) { if (error) { response.send(403, {"status": "error", "error:": exception}); } else { response.send(200, {"issues": items}); } }); } </code></pre> <p>I've gotten this far through experimentation, and now I want to test it, but I've run into a problem. How do I go about testing it, without setting up a MongoDB connection, etc. I know that I <em>can</em> set all that stuff up, but that's an integration test. I want to write unit tests to test things like:</p> <ul> <li>Does the function set the content type correctly</li> <li>Does the function sort by the <code>date</code> field</li> <li>Does the function return a 403 when an error occurs?</li> <li>... and so on</li> </ul> <p>I'm curious to see how I could refactor my existing code to make it more unit testable. I've tried maybe creating a second function that's called through, accepting the <code>response</code> and <code>Item</code> schema objects as parameters, but it doesn't feel right. Anyone have any better suggestions? </p>
