Version cycle

The set of software packages for the solution follows the following rules for naming versions.

The version is divided into 3 digits (A.B.C)
  • A: the 1st digit indicates the major version. Incrementation of this figure implies
    • the addition of major features (with potentially a loss of compatibility with the previous version)
    • adding minor features
    • bug fix
  • B: The 2nd digit indicates a minor version. Incrementing this number indicates
    • adding minor features
    • bug fix
  • C: the 3rd digit indicates a maintenance version. Incrementing this number indicates
    • bug fix

Server tree

All files handled by the server are stored in the /opt/xtc/current/ directory.


The tests are stored in the /opt/xtc/current/Var/Tests/ directory, they are organized by project ID.

Data model

A database is used by the server to store:
  • the users of the solution
  • the list of projects
  • test data (project variables)
  • statistics
  • the history of executions

Passwords management

No password (in plain text) is stored in the database. Using a hash is however used. The hash of the password is stored in the xtc-users table.

The algorithm used:


File format

The tests are in XML format. There are several test formats:
  • Test Abstract Xml
  • Xml Test Unit
  • Xml Test Suite
  • Xml Test Plan
  • Global Xml Test

Common XML Structure

<?xml version="1.0" encoding="utf-8" ?>
        <outputs-parameters>...</ outputs -parameters>

Test Abstract Xml

<?xml version="1.0" encoding="utf-8" ?>
                    <value>step description</value>
                    <value>step sample</value>
                    <value>result expected</value>

    <testlibraries><libraries /></testlibraries>
                <item-data />
    <testaborted><aborted /></testaborted>

Test Unit Xml

<?xml version="1.0" encoding="utf-8" ?>

Test Suite Xml

<?xml version="1.0" encoding="utf-8" ?>

Test Plan Xml

<?xml version="1.0" encoding="utf-8" ?>
    <testplan id="0">
            <color />
            <alias />
            <description />

Test Global Xml

    <testplan id="0">
            <color />
            <alias />
            <description />

Storage of test results

The test results are stored on the server in the /opt/xtc/current/Var/TestsResult directory.

The results are stored:
  • by the id of the test projects
  • by the date of the day of execution of the test
  • and finally by the date and time of the tests.

Organization of the results:

Répertoire: <project_id>
    - Répertoire: <yyyy-mm-dd>
        - Répertoire: <yyyy-mm-dd_hh:mm:ss.testid.testname.username>
            - Fichier: TESTPATH
            - Fichier: test.out
            - Fichier: test.ini
            - Fichier: <testname>_<replayid>.hdr
            - Fichier: <testname>_<replayid>_<result>_<nbcomments>.trv
            - Fichier: <testname>_<replayid>.tbrp
            - Fichier: <testname>_<replayid>.tdsx
            - Fichier: <testname>_<replayid>.trd
            - Fichier: <testname>_<replayid>.trp
            - Fichier: <testname>_<replayid>.trpx
            - Fichier: <testname>_<replayid>.trv
            - Fichier: <testname>_<replayid>.trvx

Description of files:

  • TESTPATH contains the full path for the test result
  • test.out contains the internal logs of the test, to be used to debug the test framework
  • test.ini contains test-specific parameters
  • <testname>_<replayid>.hdr represents the header of the test result
  • <testname>_<replayid>_<result>_<nbcomments>.trv contains all the events generated during the execution of the tests
  • <testname>_<replayid>.tbrp contains the basic report in html format
  • <testname>_<replayid>.trp contains the full report in html
  • <testname>_<replayid>.trv contains the results report in csv format

Control Agents

The control of the agents since a test is carried out through:
  • the adapters
  • and the server
The communication takes place with the exchange of some specific messages:
  • init: allows to initialize an agent
  • notify: send a message to the agent without waiting for a response
  • reset: allows to reset the agent
  • error: allows the agent to send an error to the adapter
  • data: allows the agent to send data to the adapter
Direction of available communications:
  • Agent -> server -> adapter -> test
  • Test -> adapter -> server -> agent
Function Callback
Send an error message def sendError * request * data  
Send a “notify” message def sendNotify * request * data  
Send a “data” message def sendData * request * data  
Receiving an “init” message   def onAgentInit * customer * tid * request
Receiving a “reset” message   def onAgentNotify * customer * tid * request
Receiving a “notify” message   def onAgentReset * customer * tid * request
Function Callback
Receiving an error message   def receivedErrorFromAgent * data
Receiving a “notify” message   def receivedNotifyFromAgent * data
Receiving a “data” message   def receivedDataFromAgent * data
Send an “init” message def initAgent * data  
Send a “reset” message def resetAgent  
Send a “notify” message def sendNotifyToAgent * data
