Today´s ubiquitous internet access has opened new
opportunities for mobile workers. By using portable devices, the
workers are not only able to access their company´s data and/or
services from everywhere, but are also offering their own services
for being accessible on-demand. The result is on the one hand a
higher flexibility, in terms of coordination, but on the other hand
poses various challenges to the company´s internal workflows due
to the dynamic nature of mobility. Consequently, the workflows
must be tested at runtime in realistic scenarios in order to get
evidence about their correct execution. In this paper we present
an approach for emulating mobile workers in order to test the
effects of unreliable dependability on workflows. By using the
Genesis2 framework we generate testbeds consisting of real Web
services and simulate their QoS as well as mobility issues such as
packet loss, delay, and an unreliable availability. By generating a
running testbed environment, our approach allows to investigate
a workflow´s execution at to detect runtime faults.
