bugs occur at different rate depending on the characteristic of the
software systems. Automatically collecting bugs from online or offline
source (e.g., issue repositories) and visualising them over time help
understand the reliability of the system and predict its future
behaviour. A simple tool that mines the repository and visualise
optimal curves representing the occurrences of bugs over time will be
A dataset of bugs with their occurrence time stamps or an online bug
repository (e.g., Jira).
A Java - R application
that connects to the repository or the dataset and visualises both
bugs over time and the optimal curve representing their cumulative
framework for Programmable Logic Controllers
Logic Controllers are digital systems for process automation. They are
typically little or poorly tested. A library for Unit testing and
compliant to IEC 61131-3 standards languages with which PLC are
developed has been developed. A multiple case study on the efficiency
and enhancement of the library for full testing automation will be
PLC developed with IEC 61131-3 compliant languages (e.g., CodeSys)
Enhanced Unit testing library portable on different hardware devices.
A study on the portability and efficiency of the tests.
Automated UI tests
UI often requires a long manual selection of the input values.
Selecting the input values with which to design test with high code
coverage is an art. Techniques for UI testing vary depending on the
data structures used by the interface. Testing for all combinations of
input values is often unfeasible or expensive. Based on the available
knowledge of the input space, an algorithm to reduce the combination
of the input values will be designed.
UML class diagrams and the Java implementation of such classes and
their input space.
An algorithm that identifies combinations of input values with which
to design test cases with high code coverage.
