what is selenium and what can you learn in the training?

Selenium is a suite of different tools meant for browser automation, including Selenium WebDriver and Selenium Grid. Although not limited to be used for testing web applications, it has become the most sought-after tool by software testers. With support for all of the widely used browsers, it has also grown beyond just being another software testing library. It is the backbone of countless browser automation tools, APIs and frameworks. The WebDriver interface introduced by Selenium WebDriver is under review for becoming a W3C standard, which would further increase its importance in the space of test automation.

About the course

SeU - Certified Selenium Engineer (CSE) is a practitioner level course for testers involved in web test automation. The course covers Selenium as a browser automation library from the ground up and includes coverage of advanced concepts such as page object design, custom implementation of listeners etc. Test automation constructs and design are kept to a minimum to better focus on code constructs that enable usage of Selenium in a properly designed manner. This course, together with future test automation design-focused courses from Selenium United, provides testing practitioners everything that is required to become successful test automation engineers in the web test automation space.

Introduction webinar:


SeU - Certified Selenium Engineer (CSE) offers its participants the un-diluted Selenium experience. Other similar courses tend to cover non-Selenium topics such as TestNG, Reporting, CI, Cucumber etc, which tends to bulk up the course, but alter the focus on key features of Selenium that are crucial in practice. This is why SeU - Certified Selenium Engineer (CSE) allows the participants to focus more on the critical Selenium concepts, so they better understand how to implement Selenium into their daily work.

Another important differentiator is that Selenium United believes in the importance of practical training, which is why over 70% of the course consists of hands-on exercises, which allows participants to also gain experience and implement as they learn.

SeU - Certified Selenium Engineer (CSE) is a hands-on course that deals with the Selenium concepts in a very practical way (30% theory, 70% practical)

  • This course is a comprehensive certification aimed at anyone involved in developing and implementing automated web app automation using Selenium
  • This course also provides full coverage of web test automation using Selenium, including all relevant techniques and terminology from the most basic to the most advanced concepts
  • SeU - Certified Selenium Engineer (CSE) is a 3-day course, followed by a 60-minute certification exam at the end of the last day.

We know that you can learn best when you feel good! Therefore, you receive not only a first class training but also an all around-catering and supervision.

open and in-house courses

If you want to determine the time and location of your training yourself, then our coach will come to you. With our in-house courses, everything is based on the wishes of our customers. Here you can see our range of in-house training courses. Go to our training

If you don’t wish to spend time and effort organising a training course, but simply want to register and get going while meeting new colleagues in your sector, then come to our open courses. Registration is on a first-come, first-served basis. Go to in-house training

small learning groups

As a training participant, you of course benefit from learning in a group and the experience of the other participants. Yet to ensure that you get to pose all of your own questions, we keep the group sizes very small, with a maximum of 10 participants. This allows our coaches to make certain that we meet the needs of all participants, even if the participants’ levels of existing knowledge differ.

date guarantee

Our courses are guaranteed to take place from as few as four participants, and provide you with long-term planning certainty for your training activities.

experienced trainers

In addition to their teaching work, all of our trainers have been and continue to be involved in projects, with each of them possessing more than 15 years of professional experience in various sectors. They have also all additionally acquired teaching qualifications. It is important to us not just to teach the training material, but also to enable each participant to enact what they have learned in the workplace. The point is for it to not feel superimposed, but instead for the acquired knowledge to be incorporated effortlessly into your own work.

early-booking and group discounts

You already know your training needs for the next year and would like to come to our trainings with several people? Then let us know! It helps us to be able to plan ahead, and we are therefore happy to offer you a discount.
By the way: a 15% early booking discount is available until 8 weeks before your course starts.

examination service

The DIN/ISO 17024 requirements stipulate that training companies cannot themselves provide the examination. An independent certification institute carries out the examination, not least to ensure the independent quality control of our training courses. We offer you the services of the certification institute so that you don’t incur the additional hassle of securing an examination appointment. We invoice the examination fee and organise your exam at the end of the course. You can simply focus on getting prepared.

fresh break-time snacks & a delicious lunch

We know that a sense of well-being helps you learn better. This is why we provide not only fresh knowledge, but also comprehensive catering during all breaks, with fresh and dried fruits, as well as other nerve-soothing foods ranging from nuts to biscuits. A lunch with all participants and our coaches is also a fixed part of our catering package.

hot and cold drinks

We ensure a limitless supply of hot and cold drinks throughout the duration of the course. So you can leave your thermos flask and water bottle at home, and let us serve you.

lean coffee or lean pizza event

Some of the course content requires further discussions and, when considered in-depth, throws up further questions which cannot be resolved within a normal training day. To this end, for all our 4- and 5-day courses we offer an in-depth session on one morning or evening, including catering. The participants jointly agree whether they would prefer to get up earlier or stay later, and which topics they would prefer to explore in greater depth with our coach in an informal atmosphere.

free wifi

We offer free WIFI at all our training locations. To allow you to quickly get to work at our premises, let us know in advance of the course and we will provide you with access details and a password.

feel-good atmosphere

We don’t hold with dilapidated offices that are unfit for running a business from but which are deemed good enough for a week’s training, and whose lack of light makes it easier to read the PPT slides. We know that a sense of well-being helps you learn better. That is why all our rooms are well-lit and have large windows. They feature a wealth of opportunities for creative development. Breaks are always spent outside the classrooms. After all, a change of scene is a key element to then being able to once more concentrate on the course content. And we of course also provide a sufficient supply of hot and cold drinks, as well as the necessary nerve-soothing snacks. Is there anything else we can help you with? Then please let us know! We make many things possible.
