Thuringia’s Open-Source Prize for XLT

Wolfgang Tiefensee, Thuringia’s Secretary of Commerce, in conjunction with the board of directors of the IT industry network ITNet Thuringia, awarded the first Thueringen Open-Source Prize to three companies, all of them software companies based in Jena: TRITUM, Xceptance and GraphDefined.

Open Source Prize Title Picture Second Place

It is an honor for Xceptance to be the second-place winner of this competition. This result clearly demonstrates that open source as a component of commercial products can be a clear competitive advantage. XLT incorporates a number of open-source projects, including Apache HttpClient, Jetty, HtmlUnit, JUnit, and the Apache Commons libraries. As part of developing XLT, Xceptance is involved in testing and providing feedback for these projects, thus giving back to the open-source community.

While XLT is itself not open source, Xceptance does provide the software free of charge and with virtually no usage restrictions, so for most applications there is no noticeable difference to open-source software.

Neodymium – An Open Source Framework for Web Testing

TL;DR: Neodymium is a Java-based test library for web automation that utilizes existing libraries (Selenide, WebDriver, Allure, JUnit, Maven) and concepts (localization, test multiplication, page objects) and adds missing components such as test data handling, starter templates, multi-device handling, and other small but useful everyday helpers.

Motivation

As a company focused on quality assurance and testing, Xceptance always needs test automation software, especially end-to-end automation software. Several years ago we built a Firefox add-on that was designed to create and run browser automation. The tool was primarily used by people who didn’t necessarily have a strong background in software development. Today, the landscape is a bit different: Mozilla cut the cord on the APIs we were using and standard programming languages have largely taken over test automation because they are more flexible and less proprietary. These changes convinced us it was time to implement an idea we had already hatched, namely our own Open Source test automation project: Neodymium. It is written in and utilizes the Java platform, it is MIT licensed, and of course you will find it on GitHub: https://github.com/Xceptance/neodymium-library

Basis

There are many libraries out there to aid web automation in Java, so developers are faced with the task of choosing ones they like and somehow making them work together. On top of that, there are tasks that require some custom code to work properly. We identified the overall tooling problem mostly as a hurdle in getting started and setting up a project. Finally, there are always things missing such as test data handling, concurrency, and common patterns which you don’t want to have to develop yourself. We chose JUnit, Selenide, WebDriver, Maven, and Allure for the base tooling.

Selenide provides an easy-to-use API to control Selenium WebDriver. Allure offers good mechanics to generate useful reports based on the assertions and actions you perform throughout your test cases. Maven is used to set up the build and execution environment for our framework and all the test projects. We decided to use JUnit as the test runner since it is the de facto standard in the Java world, but we enhanced the capabilities of JUnit to do even more. At its heart, Neodymium is a JUnit runner that wraps default JUnit behavior and adds significant useful functionality to it.

Multiple Browsers

You want to be able to run the same tests for different resolutions and/or browsers to simulate the browsers most common among your users. Additionally, you need to be able to implement small differences within your test execution to address variants such as responsive designs or progressive web apps. So we added a way to run web browsers with different configurations and retrieve the current device type and resolution from within the test.

Neodymium provides a Java annotation that can be added to your test case, in order to run different browser setups. Neodymium is very flexible in configuring browsers, allowing you to fully leverage the Chrome device emulation offerings.

Test Data

Another common task is the execution of a test case with different data sets, such as testing address forms with all the relevant variations. The basic idea is to have test data and data sets in structured files next to your code, preferably as JSON, XML, property style, or simply CSV. Hence, we introduced an easy-to-use API to access the current data set and retrieve basic types from it. Furthermore, you can configure specific scenarios running only a subset or even no data set at all by adding proper annotations. To complete the picture, Neodymium supports test data on a global and package-level scope.

Localization

Another recurring topic in modern software projects is localization. Most of the web sites that are in need of test automation also support several locales. We decided to provide an out-of-the-box solution.

Neodymium’s localization feature makes use of a central translation file written in YAML format. YAML helps to structure the translations. Additionally, we implemented a simple way to override specific translations for different locales. The localized text can be easily retrieved using Neodymium API methods that are globally available.

Development Support

As it is essential to understand what your test is doing, we added a feature that enables you to slow down the test execution and highlight elements that match the current selector. Since you can chain selectors using Selenide, any chain of elements is also represented by the highlighting. With this feature activated, a developer can track down the cause of test failures much more easily. In addition, we provide information on how to set up logging in your project should you need that. Finally, we decided to use the Page Object pattern to organize the website-related code to reduce the maintenance effort and increase reusability.   

Reporting

Allure is a widely used framework to generate reports. When using Neodymium with Selenide, your automation code also contributes report information. Your test classes and methods are listed as well as detailed Selenide automation commands. In case of errors, additional details such as screenshots and source code of the page in question are available. Neodymium also provides means to structure code blocks for reporting purposes.

Continuous Integration

Implementing principles of continuous integration will deliver more reliable software by increasing efficiency, and automation is nothing without a continuous integration environment.  Yet in almost every development cycle you will eventually end up needing varied settings due to differences in your setup, which can get complicated. Neodymium provides support for extra configuration files during development to override the standard production settings as needed. Furthermore, the framework supports overriding properties that change the configuration of your test execution by setting environment variables or simply passing Java arguments.

Because automation is supposed to run quickly, Neodymium provides support for parallel test execution and also demonstrates that setup as part of the sample test suite.

XCMailr – An Open Source Test Mail Forwarder

As a software tester, an episode such as the one below must be more than familiar to you and, let’s be honest, it has the potential of making the top ten of the most annoying things in our daily work routine:

  • Pain in the neck: “Hey, I need more email addresses for testing, I just burnt all my own.”
  • You: “Well, just use a fake one.”
  • P: “Nah, I can’t, I need the activation emails.”
  • Y: “Well, then, there are good disposable mailers out there.”
  • P: “Very clever, but they aren’t protected by authentication and I signed an NDA for that project.”
  • Y: “Here, use this one.”
  • P: “But it wants to have a real email to sign me up and I don’t really feel like giving my real email away.”
  • Y: “$§5$!51z1hhsks!”

Granted, it’s a matter of course that committed testers have many email addresses but what’s the use of them when you’re always limited to a certain number, when you can’t quickly change them, or deactivate them when an email service got hold of them?

Ein Zitat zum Lieben

Es gibt Zitate, die sind so erschreckend wahr, dass man sie einfach nur lieben muss und ihnen 100% Recht gibt. Das hier stammt von Bruce Schneier aus dem Crypto-Gram 1999/09/15 und gefunden habe ich es via  KeePass.

As a cryptography and computer security expert, I have never understood the current fuss about the open source software movement. In the cryptography world, we consider open source necessary for good security; we have for decades. Public security is always more secure than proprietary security. It’s true for cryptographic algorithms, security protocols, and security source code. For us, open source isn’t just a business model; it’s smart engineering practice.
