Test
Sencha Test is the most comprehensive unit and end-to-end testing solution for Ext JS. Sencha Test helps developers and test automation engineers to:
- Improve the quality of your apps through end-to-end testing.
- Leverage unit and functional testing for Ext JS apps to increase team productivity and accelerate release cycles.
- Create robust tests by leveraging the deep integration between Sencha Test and Ext JS.
Adaptive
Ext JS includes a flexible layout manager to help organize the display of data and content across multiple browsers, devices, and screen sizes. It helps you control the components’ display, even for the most complex user interfaces. Ext JS also provides a responsive config system that allows application components to adapt to specific device orientations (landscape or portrait) or available browser window sizes.
Accessibility
Ext JS includes features that align with the ADA Standards for Accessible Design. The Ext JS ARIA package makes it possible to add accessibility support to your applications by providing tools that you need to achieve Section 508 Compliance. Using the ARIA package, you can create apps that can be used by people who need assistive technologies such as screen readers to navigate the web.
Data Package
The robust data package included in Ext JS decouples the UI components from the data layer. The data package:
- Allows client-side data collections using highly functional models that offer features such as sorting and filtering.
- It is protocol agnostic and can consume data from any back-end source.
- Comes with session management capabilities that allow several client-side operations, minimizing round-trips to the server.
