 ## Description
-This repository is the starting point for the SAP Community Code Challenge for UI5 (see [SAP Community Coffee Corner thread]() and corresponding [blog post]()). The repository contains an empty OpenUI5 project and a series of [end-to-end tests](/webapp/test/e2e/) written with [wdi5](https://js-soft.github.io/wdi5/#/). In order to take part in the challenge it is your job to develop the OpenUI5 app and make the tests pass (following the process of [test-driven development](https://en.wikipedia.org/wiki/Test-driven_development)). The purpose of the challenge is to get familiar with the **wdi5**, which will be [UI5's official end-to-end testing framework](https://blogs.sap.com/2022/02/12/the-king-is-dead-long-live-the-king-wdi5-as-uiveri5-successor/) in the future.

 As this challenge focuses on test-driven development and the wdi5 testing framework, there are no requirements in terms of what your application has to looks like or its content, as long as it passes the tests.
