Mastering Selenium WebDriver 3.0 - Second Edition

Overview of this book

The second edition of Mastering Selenium 3.0 WebDriver starts by showing you how to build your own Selenium framework with Maven. You'll then look at how you can solve the difficult problems that you will undoubtedly come across as you start using Selenium in an enterprise environment and learn how to produce the right feedback when failing. Next, you’ll explore common exceptions that you will come across as you use Selenium, the root causes of these exceptions, and how to fix them. Along the way, you’ll use Advanced User Interactions APIs, running any JavaScript you need through Selenium; and learn how to quickly spin up a Selenium Grid using Docker containers. In the concluding chapters, you‘ll work through a series of scenarios that demonstrate how to extend Selenium to work with external libraries and applications so that you can be sure you are using the right tool for the job.

Starting up Docker containers as part of the build

As we have seen, it's really easy to spin up and shut down Docker containers. Wouldn't it be useful if we could do that as part of a build?

In a perfect world, our build process would build our application and then install it in a Docker container. We would then be able to run tests against this container, and if everything worked as expected, we could publish the container in a private Docker registry. We could then take this Docker container and pass it through our promotional model until it hits live. We then would have something in live that is identical to the container that we originally built and tested. Thus, we would know that it works. If we have any problems with it in live, we can easily spin up another instance of this container in a test environment to reproduce the problem. Rather than passing around application...
