+
+**Utilities for testing LoopBack apps**
+
+## overview
+
+The following helpers are designed to generate [mocha] tests against
+[LoopBack](http://strongloop.com/loopback) apps.
+
+## install
+
+```sh
+npm install loopback-testing --save-dev
+```
+
+## basic usage
+
+Below is a simple LoopBack app.
+
+```js
+var loopback = require('loopback');
+var app = loopback();
+var Product = app.model('product');
+Product.attachTo(loopback.memory());
+```
+
+Use the `loopback-testing` module to generate `mocha` tests.
+
+```js
+var lt = require('loopback-testing');
+var assert = require('assert');
+
+describe('/products', function() {
+  lt.beforeEach.withApp(app);
+  lt.whenCalledRemotely('GET', '/products', function() {
+    lt.itShouldBeAllowed();
+    it('should have statusCode 200', function() {
+      assert.equal(this.res.statusCode, 200);
+    });
+
+    lt.givenModel('product');
+    it('should respond with an array of products', function() {
+      assert(Array.isArray(this.res.body));
+    });
+  });
+});
+```
