Combining Selenium tests with drag and drop on interactive maps

Sep

The only way to solve 90% of large complex problems is by breaking them down into small manageable subproblems. You’ve probably heard about eating the elephant one piece at a time, or starting the long trip with one small step…

What these adages describe is an approach that helped us solve a lifelong problem of UI testing with Selenium. That problem is drag-and-drop actions against embedded interactive elements like Google Maps. Not only we figured out how to fully automate this functionality, but we also implemented it within an embedded browser! Here’s how we did it.

Selenium waits: isn’t it time to move on?

How do you make Selenium WebDriver wait for page to load.

There’s an important difference between a human tester and an automated UI testing tool. This difference comes down to patience: humans are capable of it, and machines aren’t. When processing a test, an automation tool expects to obtain some result, like a button click. If the button is missing, the test fails, which is what we pretty much expect from it If the button takes too long to load, though, the test will also fail, which is certainly not the result we’re counting on.

I’m sure most people reading this blog have at least some experience with automation testing tools for web UIs. And I guess most of us can agree that no matter what testing solution we use, we all follow similar algorithms when automating UI testing.

Better Alternative to Using Selenium for Continuous Integration Testing

UI testing automation is all the fuss today. In a way, this is due to an advent of new solutions that promise to outperform the “tried-and-true” tools of the past years. But how many of these automated testing tools (both new and old) are CI-friendly? Besides, how many of them are good at handling visual testing of websites and web apps?

Let’s see what the market of UI automation testing has to offer in the way of CI support. But first, let’s answer the following question.

CI for CSS regression testing with Screenster

Nov

Now that the CI integration plugin has been successfully rolled out, it is time to recall how it all began… Ready for a tale about defeating a horde of CSS regression testing challenges with the help of a Jenkins server and a visual QA automation tool?

Why did we need CSS regression tests on our CI

Our team has realized the necessity of automating the visual regression testing process last winter, when our other product AjaxSwing gained a significant number of new users, who were actively requesting improvements. A new version was released each week, sometimes even more often. AjaxSwing generates web UI for desktop applications so you can imagine how much visual UI verification we had to accomplish each time a build was ready. It just seemed never-ending. We had unit tests in our continuous integration environment running against every new build, but they didn’t help with verifying the visual aspects of the UI such as CSS, formatting and layouts. That’s when our QA team decided it is time to try our new automation testing tool Screenster in real action, despite it being in its early Beta at the time.

Integration with CI tools — a new plugin for Screenster

Good news! Now you can easily run Screenster visual tests in your continuous integration environment. Just visit the Downloads page on our Portal, get the CI plugin and follow our guidelines to install it and synchronize with your favorite CI tool.

Automation testing of Gmail UI

Are you overloaded with web UI regression testing and finding that manual visual testing is a pain? You definitely need some automation testing tool and guess what: we have just the thing for you! Skeptical about tools abilities to handle complex sites that use not just plain HTML, Web 1.0-styled pages? You should be, because most of them suck at it 🙂 Let me demonstrate you how I built UI regression testing automation process for Gmail inbox (let us imagine we are developing new Google Mail UI) in 15 minutes.

Here’s how you can edit automated UI tests with Extend

Last week I had to record a bunch of tests for a site that required a user to be logged in. Which is why I would like to talk about one Screenster’s feature which was most helpful for me during all that time. So, let me introduce the Feature of the Week in our blog: the ‘Extend’ command!

What regression testing challenges exist on the UI level?

What regression testing challenges do you typically face when automating UI tests? And more importantly, how do you overcome these challenges? This post sums up our experience of dealing with UI regression testing and its pitfalls. But there’s one more question to ask before we can proceed: do you automate UI test in the first place?

I’m sure you know that quality control is inseparable from product development process. Some good amount of time and resources should be invested into it. New UI functionality must be covered with tests as soon as it is ready. And it is not enough to verify it once: each time an important change is introduced, the UI regression testing phase must follow.
