Improved Testing through Refactoring: Experience from the ProTest Project [chapter]

Huiqing Li, Simon Thompson
2010 Lecture Notes in Computer Science  
We report on how the Wrangler refactoring tool has been used to improve and transform test code for Erlang systems.  ...  The Wrangler tool for Erlang provides support for clone detection and removal, and this has been used effectively both for clarifying test code and in extracting higher-level properties from test suites  ...  Conclusions We have shown the various ways that refactoring tools can improve testing for Erlang programs, and reflected on aspects of each of these.  ...

Refactoring Support for Modularity Maintenance in Erlang

Huiqing Li, Simon Thompson
2010 2010 10th IEEE Working Conference on Source Code Analysis and Manipulation  
We identify a set of "modularity smells" and show how they can be detected by Wrangler and removed by way of a variety of refactorings implemented in Wrangler.  ...  Validation of the approach and usefulness of the tool are demonstrated by case studies.  ...  Acknowledgements This research is supported by EU FP7 collaborative project ProTest (http://www.protest-project. eu/), grant number 215868; we thank our funders and colleagues for their support and collaboration  ...

Safe Concurrency Introduction through Slicing

Huiqing Li, Simon Thompson
2015 Proceedings of the 2015 Workshop on Partial Evaluation and Program Manipulation - PEPM '15

A Domain-Specific Language for Scripting Refactorings in Erlang [chapter]

Huiqing Li, Simon Thompson
2012 Lecture Notes in Computer Science  
This paper introduces the domain-specific language framework of Wrangler -a refactoring and code inspection tool for Erlang programsthat allows users to script composite refactorings, test them and apply  ...  In particular, there is a lack of powerful and easy-to-use frameworks that allow users to script their own large-scale refactorings efficiently and effectively.  ...  Terminology This section introduces terminology that we use in discussing our DSL. Particularly we explain what we mean by success and failure for a composite refactoring. Definition 1.  ...

DIEL: Interactive Visualization Beyond the Here and Now [article]

Yifan Wu, Remco Chang, Joseph Hellerstein, Arvind Satyanarayan, Eugene Wu
2021 arXiv   pre-print
To specify the state of a user interface at any time, developers author declarative queries over the data and event logs; DIEL compiles and optimizes a corresponding dataflow graph, and synthesizes necessary  ...  However, for more complex use cases---e.g., remote database access and streaming data sources---developers must grapple with distributed data and asynchronous events.  ...  The work is supported by NSF 1564049, 1564351, 1942659, 1845638, 2106197, 1452977, 1939945, 1940175 , and CCF-1730628.  ...

From test cases to FSMs

Thomas Arts, Simon Thompson
2010 Proceedings of the 9th ACM SIGPLAN workshop on Erlang - Erlang '10  
This has the effect of transforming a fixed set of tests into a property which can be tested using randomly generated data, substantially widening the coverage and scope of the tests.  ...  Secondly, we use FSM inference to develop QuickCheck properties for testing state-based systems.  ...  The next step for us to take is to refine the process described here into a procedure which automates as much as possible of the FSM development.  ...

Testing Erlang Refactorings with QuickCheck [chapter]

Huiqing Li, Simon Thompson
Lecture Notes in Computer Science  
This paper first gives overviews of Wrangler and Quviq QuickCheck, then discusses the various ways in which refactorings can be validated, and finally shows how QuickCheck can be used to test the correctness  ...  With QuickCheck, programs are tested by writing properties in a restricted logic, and using the tool these properties are tested in randomly generated test cases.  ...  We also intend to provide an API to help the specification of properties in the context of refactorings, and we would also like to adopt this approach to test our Haskell refactoring tool, HaRe.  ...
