Conformiq Designer

Why One Testing Design Method Isn’t Enough

Every now and then Conformiq Designer and Creator are compared against other testing tools that employ one type of test design heuristic, for example a combinatorial testing tool for generating optimized pair-wise test data. The capability of generating such combinatorial data combinations is one testing method that in practice has been observed ...

Test Design Techniques: Conformiq’s Insights

Test design concerns making the decisions on (1) what to and what not to test, (2) how to stimulate the system and with what data values, and (3) how the system should react and respond to the stimuli. It is a separate task from test execution and is done before executing the tests against the system. Test design techniques, on the other hand, are ...

Conditional Coverage Heuristics Explained

Some time ago I wrote a short blog post about equivalence partitioning and boundary value analysis. Now with new version of Conformiq Designer coming out very soon we have introduced quite a few new testing heuristics and coverage options that are based on equivalence class partitioning I wanted to write about how Conformiq can use these new ...

Combinatorial Test Data Generation with Conformiq

Suppose a system model states that when a message comes in, it is forwarded out unchanged. This particular message has a number of fields, some of them integers, some strings. For some reason there is cause to suspect that the forwarding feature in the real implementation might be flawed, so we would like to have a number of different message ...

Distributed Test Generation

As detailed in a blog post I wrote a couple of months ago, the core of Conformiq DesignerTM is a custom crafted  semantics driven, symbolic state space exploration  algorithm for test generation from system models (because this is really the only known solution that robustly generates both test inputs and outputs from a system model without user ...

Selecting the Right MBT Tool: Key Factors

Interest towards model-based testing has increased quite significantly over the years as people have started to reach limits of traditional approaches and at the same time started to see and understand the benefits that applying MBT can have to the quality assurance function. In this blog post, I’m outlining what is really important when you are ...

ECP & BVA as Black Box Test Design Heuristics

Boundary value analysis is a refinement of the equivalence class partitioning method which again is one of the most generally applicable methods for black-box test design. The idea of equivalence class partitioning is to divide the all possible inputs to the system into “equivalence classes”, i.e. sets of inputs that should produce “analogous” ...

Extended String Testing with RegEx

Quite recently we added a support for expressing ”regular expressions” in the Conformiq models. As this is quite an interesting topic, I’m detailing this feature a bit in this post. (more…)

Conformiq Blog: Improve Your Testing Game

I recently had an opportunity to present in ETSI’s UCAAT conference a way to use component-enabled MBT to overcome some of the shortcomings with current interoperability and end-to-end testing approaches. Because this raised quite a lot of interest in the conference, I wanted to write a short blog post about the subject. (more…)

Tackling Huge System Specs in Model-Based Testing

Conformiq's system model based testing is based on the premise that you can create a (computer-readable) model of the intended behavior of the system under test. But what if the system is really big? This is a question that people often ask from us, and there are typically three concerns: (1) How long will it take to create the model? (2) Can our ...

Skill Profile of a Successful Conformiq User

Automated test design with Conformiq Designer is a new way to create, maintain and manage tests. Using Conformiq successfully requires a different skill profile than manual testing does. The crucial difference to manual testing is that manual testing typically does not require any programming skills. At the same time, creating models is quite near ...
