Junit_dev_basics
As with many objects that constitute a packaged module, module (the object) creation is two part: XML declaration and Java coding.
Module is the root element in the src/main/conf/res/module.xml file.
1 <Module
2 id="${project.name}"
3 version="${project.version}"
4 binaryversion="4.0.00"
5 class="org.modelio.junit.impl.JUnitModule"
6 schema-level="2">
-
id value is the internal name of the module. It is replaced at packaging with the module’s name from the pom.xml file.
-
version value in the V.R.C form, filled at packaging from the pom.xml file.
-
binaryversion format is the same as the version value, except it indicates the Modelio version this module needs.
-
class value is the name of the Java class that will represent the module.
-
schema-level value is used by Modelio at runtime for migration purpose.
The last files to edit are the manifest property files. There is one file per language supported with a default (without country code extension) that should be for English locale.
module.properties file will look like :
ModuleLabel=JUnit module ModuleDescription=Builds and manages test case for classes based on JUnit framework.
module_fr.properties file for french will look like :
ModuleLabel=Module JUnit ModuleDescription=Crée et gère les cas de test de classes basés sur JUnit
A module contains :
-
A JUnitModule class that will represent your module at runtime. This class is called the main class of the Module. By convention it is always suffixed Module.
-
A JUnitLifeCycleHandler class and an association. This class is in charge of the implementation of the Module Session Services detailed below. The association is a simple delegate from the Module main class to this JUnitLifeCycleHandler class.
The UML model detailed diagram for these classes is presented below.
Illustration 6: Module and Session
The operations defined in src/main/java/org.modelio.junit.impl/JUnitLifeCycleHandler.java are automatically called according to the stat Module runtime states and events.
We won’t dive into the gory details of these methods. We will see later (§7.7)that the start method will attach the module event listener to the Modelio event dispatch system. For more information on these methods.
The implementation of session services for our JUnit module is very simple.
