UI-First Development

One of the challenge for start-up or any new project is to reduce amount of work yet to deliver full-featured product. Agile methodologies address this challenge on project management level. Let’s discuss one more approach to address it on architecture level: UI-first development.

How to Start Testing UI Before Backend is Ready

Recently I was asked how to start with testing UI before backend is completed. It depends on the product a lot. But when we’re talking about web, it is often not clear how the final solution should look like and behave. If so, it is not reasonable to spend much time writing UI tests using tools like Selenium before the first prototype is ready. It is not reasonable to write a presentation layer and, in some cases, a business logic on server side before it is clear what kind of data is required for UI.

Selenium Tests with Maven and Selenide

Selenide is nice wrapper around selenium web driver allowing to simplify writting UI tests with Selenium.

Some of the cook features are:

  1. jquery-like selector syntax, e.g. $("div.myclass").is(Condition.visible)
  2. Automatic screenshots on assertion failure
  3. Easy starting Selenium WebDriver
  4. And others

So, let’s write some tests on selenide and make it run from maven in a normal browser or in headless mode.

Recalling Testing Principles

If you are involved in software development then recalling a basic testing principles once again is not a waste of time. So here are the principles: A necessary part of a test case is a definition of the expected output or result. A programmer should avoid attempting to test his or her own program. A programming organization should not test its own programs. Any testing process should include a thorough inspection of the results of each test.
