Test Portfolio, or selected industry-specific software testing stories

Posted: 2023-07-20

Over the past 12 years, we have tested scores of systems. We chose only a few for this post to demonstrate their diversity – both by topic and industry. We’ve tested railroad systems, automotive, and healthcare applications that require the highest degree of security and industry compliance. We have worked for industry, banking, and the media, co-developing software designed to streamline work, speed up processes, or implement innovations.

As one of two ISTQB Platinum Partners in Poland and the Global Leader 2023 in software testing, Solwit is capable of conducting software testing in virtually any industry, according to Clutch. Read our clients’ success stories. See if we have already completed a similar project to the one you are currently dealing with.
