+### Testing
+
+For testing purpose of your component you should export the pure component without extending with the translate hoc and test that:
+
+```js
+export MyComponent;
+export default translate('ns')(MyComponent);
+```
+
+in the test test the myComponent export passing a t function mock:
+
+```js
+import { MyComponent } from './myComponent';
+
+<MyComponent t={key => key} />
+```
+
+Or use [https://github.com/kadirahq/react-stubber](https://github.com/kadirahq/react-stubber) to stub i18n functionality:
+
+```js
+const tDefault = (key) => key;
+const StubbableInterpolate = mayBeStubbed(Interpolate);                                                                              
+const stubInterpolate = function () {
