Tue, August 23, 4:00pm – 4:30pm Youtube: https://youtu.be/5Txf774hLKY First Name: Tommaso Last Name: Dal Sasso Email: dalsat@usi.ch Title: Talking about bugs with bugs Type: Talk Abstract: We present ShoreLine, a new approach to track bugs in Pharo. With ShoreLine users can report and describe errors in a program from the image, without stopping the conversation with the system. Reporting bugs is easier and faster, since you can attach any kind of information, not just text: you can easily configure the system to collect your custom data. ShoreLine allows you to access the information about defects from the image and connect together the different pieces of data, to build a knowledge graph of your system. Bio: Tommaso Dal Sasso is a PhD student in Software Engineering at the University of Lugano, in Switzerland. He works with Professor Michele Lanza to improve the way developers describe software defects and interact with bug reports.

how to collect the data
SlCollector class>>description
a text description of the collected data
SlCollector class>>tag
the name of the collector

17. Domain Specific Information
‣ Roassal — number of nodes in a view
‣ PetitParser — input string
‣ Voyage — object description

21. Shards
Each shard knows its context
Each Shard can be linked to other shards
Many linked shards form a stream that describes a behavior

22. Talking With Bug Reports
‣ Bug reports are objects
‣ Events are objects
‣ Links are objects
We can inspect and navigate our data

26. ShoreLine Design Principles
‣ Extensible
‣ Privacy Friendly
‣ “Business” Friendly

27. What Next?

What is There What is Not There Yet

28. Short Term Plans
‣ Stable version
‣ Report Browser
‣ Interaction with FogBugz
‣ Data Analysis
