Darmstadt, September 2025 – PROSTEP and Wecon PLM, an IT consulting company and service provider that specializes in software development, test and project management, will in the future collaborate more closely on customer projects. PROSTEP will market Wecon PLM’s RelAIable software for automating software testing and provide customers with support when integrating the solution in their IT landscapes. The joint offering is aimed not only at big-name customers in the automotive industry, who for example want to check whether or not the customized user interfaces for their PLM or ALM solutions are functioning correctly. It is also aimed at machine and plant manufacturers as well as medical equipment manufacturers, who are faced with the challenge of continuously improving the operation of their machines and devices.
Testing graphical user interfaces is one of the most important and time-consuming tasks involved in software development. It is difficult to automate testing using conventional methods, which is why testing is usually performed by offshore or nearshore teams. Wecon PLM has developed software for this purpose that automates the processing of test cases with the help of artificial intelligence (AI). The software can be used to test both web and desktop interfaces as well as apps for mobile devices.
RelAIable makes it possible to generate scripts for testing graphical user interfaces based on natural language specifications using multimodal large language models (LLM) and to automatically adapt these scripts when changes are made. The test cases can be specified directly in RelAIable or imported from tools like Xray. The software can be integrated seamlessly in all leading test management environments such as JIRA/Xray, ALM Octane and Azure DevOps Server.
The software for automating testing was actually designed as a SaaS solution, but it can also be installed on-premises. “When testing user interfaces for big-name customers, confidential data is almost always involved. We have therefore designed the tool chain to run on site at the customer’s premises and use their AI infrastructure and/or language models. This is a key unique selling point as it protects their intellectual property and makes it easier for them to comply with data protection regulations”, as Bernd Weber, managing director of Wecon PLM, points out.
PROSTEP and Wecon PLM have already worked together successfully on a number of projects for BMW. “This gave rise to the idea of stepping up this collaboration for the mutual benefit of both companies,” says Norbert Lotter, Head of Near- and Offshore Operations at PROSTEP, commenting on the collaboration. “We are currently carrying out a proof of concept (POC) at another German carmaker with the aim of demonstrating the potential for automation and savings using real-life use cases.”
The use of RelAIable helps simplify the testing of user interfaces dramatically and reduce related costs. Time savings of up to 90 percent – especially in the case of automatically “repairing” test scripts following software changes – make continuous testing and a fast return on investment possible.
