CATG is a concolic unit testing engine for Java programs. The implementation uses ASM for instrumentation. ASM instrumentation instruments (see janala.instrument.) class files at runtime and dumps (see janala.logger.) to a file a log of all instructions executed by the program and all values loaded from local stacks and heaps. A concolic execution engine (see janala.interpreters.*) then takes the log and performs both symbolic and concrete interpretation of the logged instructions.

You must have java, gradle, cvc4 (http://cvc4.cs.nyu.edu/downloads/), and python 2.7 in your PATH. Two extra jar files are needed to run the tool. Create a lib directory in the root directory and download two jar files

CATG alternatives and similar libraries

Based on the "Formal Verification" category

  • Checker Framework

    Pluggable type systems. Includes nullness types, physical units, immutability types and more.
  • OpenJML

    Translates JML specifications into SMT-LIB format and passes the proof problems implied by the program to backend solvers.
  • jCUTE

    2.8 0.0 L1 CATG VS jCUTE
    Concolic unit testing engine that automatically generates unit tests. Concolic execution combines randomized concrete execution with symbolic execution and automatic constraint solving.
  • Daikon

    2.8 8.2 L1 CATG VS Daikon
    Daikon detects likely program invariants and can generate JML specs based on those invariats.
  • JMLOK 2.0

    Detects nonconformances between code and JML specification through the feedback-directed random tests generation, and suggests a likely cause for each nonconformance detected.
  • Java Modeling Language (JML)

    Behavioral interface specification language that can be used to specify the behavior of code modules. It combines the design by contract approach of Eiffel and the model-based specification approach of the Larch family of interface specification languages, with some elements of the refinement calculus. Used by several other verification tools.
  • KeY

    The KeY System is a formal software development tool that aims to integrate design, implementation, formal specification, and formal verification of object-oriented software as seamlessly as possible. Uses JML for specification and symbolic execution for verification.
  • Krakatoa

    Krakatoa is a front-end of the Why platform for deductive program verification. Krakatoa deals with Java programs annotated in a variant of the Java Modeling Language (JML).
  • Java Path Finder (JPF)

    JVM formal verification tool containing a model checker and more. Created by NASA.
