Video: Verifysoft - our History since 2003 (and before...)


Although Verifysoft has been founded in 2003, the history of Verifysoft’s testing and analysis tools with the brand name "Testwell" have started already many years before when TBGEN and TCMON (unit test tool and code coverage analyzer for Ada) have been released 1984 and 1985 in Tampere/Finland. Testwell CTB, a unit testing tool for C, was released in 1988. CTC, a coverage analyzer for C was ready in 1989 and two years later extended as CTC++ to C++.
The initial versions of "Testwell" products have been developed at the Tampere site of companies Oy Softplan Ab, Nokia Data Systems Oy and ICL Personal Systems Oy. Softplan was an innovative software house, a subsidiary to Nokia Data, later merged to its parent. Nokia Data was the computer manufacturing branch of the Nokia Corp., later acquired by ICL Plc.
The Ada tools got born along with Softplan's participation to Nokia's Ada-based MPS 10 computer systems software development. Later similar tools were developed on C/C++.
In 1992 Testwell Oy was founded in Tampere by Mr. Olavi Poutanen as MBO arrangement from ICL. Company's initial focus was at Ada side, but already in 1993 also the C/C++ side testing tool rights were acquired from ICL.
The tools got Testwell-branding and were ported to a new platforms. All tools were developed onwards, biggest effort was put to CTC++.
Further milestones:
  • 1998: Testwell CTA++ v2.0 (major rewrite/redesign)
  • 2000: Testwell CTC++ v5.0 (major rewrite and redesign which has enabled the Testwell CTC++ customer promises "works with any compiler" and "works with any target"
  • 2001: Testwell CMTJava (Complexity Measured Tool for Java, like CMT++ but for Java)
The intellectual property rights for all these tools reside today with Verifysoft (TBGEN, TCMON, CTB were discontinued 2003).


The company Verifysoft Technology was created on the 18th of June 2003 in the Technologiepark of Offenburg (Germany) by Klaus Lambertz, Roland Bär, Patricia Gallien and two other investors. Verifysoft starts as distributor for Testwell and sells Testwell tools to Germany, Austria, Switzerland, France, Benelux, and Eastern Europe.


Verifysoft signs a distribution contract with the company Conformiq (Finland) for their model based testtool.


Thanks to a contract signed with a tool editor from San Francisco, Verifysoft opens up to the static code analysis market.


Verifysoft expands the possibility of the Test Coverage Analyzer, Testwell CTC++ with Java and C# on top of C and C++.
