 ### Generators support
 
 ```javascript
-test("my async test with generators", function* () {
+test("my async test with generators", function* (assert) {
     var data = yield asyncFn();
-    equal(data, {a: 1}, 'generators work');
+    assert.equal(data, {a: 1}, 'generators work');
 });
 ```
 
 ### Run tests
 
 ```bash
-$ npm i
-$ npm test
+$ npm it
 ```
