Drools Tester

A web app that automatically runs verification tests against a Drools rules package created in Drools Guvnor.

Drools 5.6.0.Final is supported. More details about Drools Guvnor can be found in documentation.

Build from source code

  1. Clone the repository:

     git clone [email protected]:ailabitmo/drools-tester.git

  2. Create MySQL database and configure the connection. Take a look at "Configure database" section below.

  3. Compile and package to .war file:

     mvn clean install

  4. Find the .war file in /target/ folder.

Installation

  1. Create and configure MySQL. Take a look at "Configure database" section below.

  2. Compile the app from source code or download the latest pre-packaged .war file.

  3. Copy the .war file in /webapp/ folder in Tomcat 7

  4. Create tests folder in Tomcat 7's root folder and a folder for each test, e.g. assignment-<test number>. Example folder structure:

     /opt/tomcat7/tests/
 /opt/tomcat7/assignment-1/
 /opt/tomcat7/assignment-2/
 ...

  5. Run Tomcat 7

Configure database

By default the application connects to MySQL on localhost to dt-db database with dt-user username and dt-password password. The all tables are created automatically.

If you want to change the database settings then edit src/main/resources/META-INF/persistence.xml file and recompile the application.

Write a test

A verification test is set of files containing one models.json file and several test<number>.json files, e.g. test1.json, test2.json. Each verification test should be placed in a folder with assignment-<number> name in the ${CATALINA.HOME}/tests folder.

Specification for models.json

Sets requirements to classes and their fields, such the class name, the name and the type of a field. Some supported types: BigDecimal, String, Boolean and etc. More in documentation. An example:

[
    {
      "className": "Input",
      "fields": {
          "id": "BigDecimal",
          "color": "String"
      }
  },
  {
      "className": "Output",
      "fields": {
          "isTarget": "Boolean"
      }
  }
]

Specification for test<number>.json

This file consists of two parts: insertions and expectations. The insertions is a list of instances that are inserted in the working memory, each instance have:

  • className - name of the class
  • variable - name of the variable that the instance is assigned to
  • values - list of the fields and its values

The expectations is a list of instances that are expected to be in the working memory at the end of execution.

An example:

{
    "insertions": [
        {
            "className": "Input",
            "variable": "input",
            "values": {
                "constancy": 0.5,
                "consistency": 2,
                "color": "белый"
            }
        }
    ],
    "expectations": [
        {
            "className": "Output",
            "values": {
                "isTarget": false
            }
        }
    ]
}
