Research code and data prepared with love

Here, I list notable repositories from our recent research projects.

Selected code repositories

• Code analysis tools:
  • Spoon is a library to analyze and transform Java source code
  • Gumtree-Spoon computes AST diff scripts for Java, it is based on the generic Gumtree engine (which also works for Python, R, Ruby, C, etc.)
  • Coming automatically analyzes Java commits
• Chaos engineering tools:
  • TripleAgent identifies failure-oblivious methods in Java
  • ChaosMachine inject exceptions in micro-services
• Automatic repair tools:
  • Repairnator is a program repair bot for continuous integration
  • Sequencer generates one-line patches with sequence-to-sequence learning
  • Styler repairs of Checkstyle errors with LSTM
  • Astor is an extensible program repair framework for Java
  • Nopol repairs conditional bugs with code synthesis
  • NpeFix repairs null pointer exceptions in Java
• Testing tools:
  • Dspot strengthens your tests with additional assertions
  • Descartes points to badly tested methods
