Dear all,

Next Tuesday (26/09) Dr. Lorena Gutiérrez-Madroñal (
https://ucase.uca.es/lorena-gutierrez-madronal) will give a talk titled
"Testing IoT systems through IoT-TEG" in MB564 from 2pm to 3pm.

This will be the first talk of this year's seminar series. I'm looking
forward to seeing you there,
Luca

Abstract:

Internet of Things (IoT) has been increasingly become popular in different
areas. One of the main drawbacks of the IoT systems is the amount of
information they have to handle. This information arrives as events that
need to be processed in real time in order to make correct decisions. As a
consequence, new ways (tools, devices, mechanisms...) of obtaining,
processing and transmitting information have to be put into action. It is
worth mentioning the “Event Processing Languages” (EPL), which were created
to detect, in real time, interesting situations in a particular domain.
These languages use patterns to filter the information. A huge amount of
data is processed and analysed by EPLs, so any programmer error could
seriously affect the outcome because of a poor decision making system.
Given that processing the data is crucial, testing and analysing programs
which run any EPL language is required. The most common mistakes that
programmers could make have to be detected. A large number of events with
specific values and structures are needed to apply any kind of testing in
programs which use EPL. As this is a very hard task and very prone to error
if done by hand, a method is presented, which addresses the automated
generation of events. This method includes a general definition of what is
an event type and its representation is proposed. Additionally, IoT-TEG
event generator is developed based on this definition. Results from
experiments and real-world tests show that the developed method meets the
demanded requirements.
