Software is made of code. Well, yes, but not exclusively. Software engineering involves working with many other artifacts, such as models, architectures, tickets, build scripts, … and tests.
The goal of Teamscale is to provide meaningful and useful information about all aspects of software engineering. This is what we call »Software Intelligence«.
Consequently, in addition to providing profound insights into code quality, Teamscale performs many other sophisticated analyses, including architecture conformance analysis, analysis of issue tracker data, team evolution analysis, code ownership analysis, or data taint security analysis.
Moreover, Teamscale contains a bunch of analyses for

Am 25. Oktober 2017 fand zum zweiten Mal der CQSE Software Intelligence Workshop statt. Der Workshop lief dieses Jahr unter dem Motto »Software Intelligence bei…«.
Hauptbestandteil des Workshops waren Vorträge unserer Kunden mit Erfahrungsberichten, wie Software Intelligence bei ihnen jeweils konkret zum Einsatz kommt. Wir möchten uns bei den über 100 Teilnehmern herzlich für die wertvollen Diskussionsbeiträge bedanken.

Test Gap Analysis identifies changed code that was never tested before a release. Often, these code areas—the so called test gaps—are way more error prone than the rest of the system, which is why test managers typically try to test them most thoroughly.
We introduced Test Gap Analysis in many projects and used it on a wide range of different projects: from enterprise information systems to embedded software, from C/C++ to Java, C#, Python and even ABAP.
We thereby learnt a lot about factors that affect the complexity of the introduction. In this post, I want to highlight a few important factors, which I think are good to know before starting with Test Gap Analysis.

In a recent blog post, I wrote about Test Gap analysis—our analysis that identifies changed code that was never tested before a release. Often, these areas—the so called test gaps—are way more error prone than the rest of the system, which is why test managers try to test them most thoroughly.
Test Gap analysis provides test managers with an overview of remaining test gaps during the test phase. In practice, our code quality software Teamscale identifies changed but untested methods in the source code and displays the results on a treemap.
However, in many projects testers are non-coders or do not know the source code,

Many companies employ sophisticated testing processes, but still bugs find their way into production. Often they hide among the subset of changes that were not tested. Actually, we found that untested changes are five times more error prone than the rest of the system.
To avoid that untested changes go into production, we came up with Test Gap analysis—an automated way of identifying changed code that was never executed before a release. We call these areas test gaps. Knowing them allows test managers to make a conscious decision, which test gaps have to be tested before shipping and which ones are of low risk and can be left untested.
A short while ago, we introduced Test Gap analysis into our code quality software Teamscale. In
