Step 1: Get Started withSenchaCmd 6 App

You can also take the getting started guide by following this link: https://docs.sencha.com/extjs/6.2.0/guides/getting_started/getting_started.html

Step 2: Generate New App

sencha -sdk /path/to/extjs/framework generate app NewAppNewApp
cd NewApp
sencha app watch

This will generate the files in the New App Folder in an organized fashion. You will see model, store and view folders along with app.js, this will bootstrap the application for further development process. Now, navigate the folder to the local host in your browser and then you will able to view the application in tabs with grid panel.

Step 3: Build Testing Control

This step will finally commence the testing for you. Firstly, we will create a testing folder for the testing operations. Since the app is running now, you need to create the test folder in the root of the ‘NewApp’ Folder. Now, you need to inject the harness for testing. So include your harness HTML pages that contains the Ext JS applications files and a Harness JS file. This file shall contain the details of the testing process.

 Putting the Harness Using Siesta

Step 4: Conduct Unit Tests

In order to conduct a unit test using Siesta, the testing team needs to ensure that the JS classes are injected into every test of the application. The good part is that instead of using ‘preload’, Ext JS 6 will use ‘pageUrl’ and then set it to root index.html page. Once you run the above mentioned test, the application will start but you don’t need it to start while the unit tests are running. So all you need to do is modify the app.js folder by adding an inline check for ‘unittest’ string the in query string.

Step 5: Write Basic Unite Test

Use the Suite

You can use the runnable test suite online if you wish to run these tests yourself and inspect the sources of each test. Click here to see the testing suite: http://bryntum.com/temp/testing-cmd/tests/

Summing Up

It is very easy to test applications built with SenchaCmd and you can start with the unit testing as suggested above. You can also use the vendor instead of the local host when youare building your testing control/ harness. If you face any issues while using these steps, you can always get in touch with our Ext JS development experts and we will get back to you immediately. We hope this read was hopeful in making your Ext JS apps more authentic.
