Projects in this Repository

UML-Annotator

Tool to annotate Visual Studio UML models.

UML-Parser

Tool to convert UML models to a standard output for this project.

Output schema:

{
  "className": {
    "name": "Name of class",
    "variables": {
      "variableName": {
        "name": "Name of variable",
        "visibility": "Public/Private",
        "type": "Type of variable"
      },
      /* ...Next variable */
    },

    "methods": {
      "methodName": {
        "name": "Name of method",
        "visibility": "Public/Private",
        "type: "Return type of method",
        "arguments": {
          "argument": "Type of argument",
          /* ...Next argument */
        },

        "preconditions": [
          {
            "id": "UUID for this precondition",
            "comparison": "Comparison name",
            "arguments": [
              "Name of variable or method argument or direct value",
              /* ...Next argument */
            ]
          },
          /* ...Next precondition */
        ],

        "postconditions": [
          {
            "id": "UUID for this postcondition",
            "comparison": "Comparison name",
            "arguments": [
              "Name of variable or method argument or direct value",
              /* ...Next argument */
            ]
          },
          /* ...Next postcondition */
        ]
      },
      /* ...Next method */
    }

  },
  /* ...Next class */
}

For list of comparison names, see comparisons.json.

Input-Generator

Tool to generate inputs for tests.

Extends schema of UML-Parser, with an additional tests array on each method:

{
  "className": {
    ...
    "methods": {
      "methodName": {
        ...
        "tests": [
          {
            "condition": "Text identifying the meaning of the test",
            "arguments: {
              "argument": "Value of argument",
              /* ...Next argument */
            }
          },
          /* ...Next test */
        ]
      },
      /* ...Next method */
    }

  },
  /* ...Next class */
}

In order to generate inputs, the design of this section is for submodules to handle specific types for the test. Currently, only numerical logic is handled by the Input-Generator, though more is planned.

SMT-Solver

The SMT-Solver handles Boolean and Numerical Logic. Implementation is handled via the conversion of the annotated constraints on the methods into Satisfiability Modulo Theorem, SMT. Then by using Microsoft's z3, the constraints are solved to generate values that satisfy the constraints.

Test-Generator

Tool to take the UML model and inputs and generate the test suite.

Installation

This is a project dependent on C# (For UML-Annotator) and Node.js (For UML-Parser, Input-Generator and Test-Generator).
This project also uses ES6 syntax, which requires node version v6.0.0 at minimum.

Please ensure that node and npm are installed and available in your PATH, to correctly run this project.
Also check that node --version matches at least v6.0.0.
