Why ?
The system under development is a bridge between your Fixtures and the system your testing.
If you want to change the way GreenPepperGreenPepper is finding/instanciating your fixtures, or if you need to hook the document execution then you can define a Custom System Under Development.
Changing how
...
GreenPepper is finding your Fixtures
This could be useful when you are using for example an IOC, like Spring (see Spring Example) or just when you want to add locations (packages in java, namespaces in .Net) for 
GreenPepper can resolve your fixtures.
To change the system under development :
- With GreenPepper Server : Server system under development configuration
- With GreenPepper Open : Command line system under development configuration
Only for specifying location to resolve fixtures (packages in java, namespaces in .Net)
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
public static class CustomSystemUnderDevelopment extends DefaultSystemUnderDevelopment {
public CustomSystemUnderDevelopment( String... params )
{
super.addImport("com.mycompany.fixtures");
super.addImport("com.mycompany.specials.fixtures");
}
} |
By this custom system under development you tell GreenPepper to look in "com.mycompany.fixtures" and "com.mycompany.specials.fixtures" to resolve fixtures in specfications that your are running.
Changing Fixture instanciation mechanism (Spring example)
| Code Block | ||||
|---|---|---|---|---|
| ||||
package com.greenpepper.extensions.spring;
import ...;
public class SpringSystemUnderDevelopment extends DefaultSystemUnderDevelopment
{
private BeanFactory beanFactory;
public SpringSystemUnderDevelopment(String... applicationCtxes)
{
this.beanFactory = new GreenPepperXMLAplicationContext(applicationCtxes).getBeanFactory();
}
public SpringSystemUnderDevelopment(BeanFactory beanFactory)
{
this.beanFactory = beanFactory;
}
@Override
public Fixture getFixture(String fixtureName, String... params) throws Throwable
{
Fixture fixture;
if (params.length != 0)
{
fixture = super.getFixture(fixtureName, params);
}
else
{
try
{
fixture = new DefaultFixture(beanFactory.getBean(fixtureName));
}
catch (NoSuchBeanDefinitionException e)
{
fixture = new DefaultFixture(instantiateAsAutowiredBean(fixtureName));
}
}
return fixture;
}
private Object instantiateAsAutowiredBean(String fixtureName) throws Exception
{
Class fixtureClass = loadType(fixtureName).getUnderlyingClass();
BeanDefinition beanDef = new RootBeanDefinition(fixtureClass, RootBeanDefinition.AUTOWIRE_AUTODETECT);
DefaultListableBeanFactory fallFactory = new DefaultListableBeanFactory(beanFactory);
fallFactory.registerBeanDefinition(fixtureName, beanDef);
return fallFactory.getBean(fixtureName);
}
} |
Hooking document execution
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
public static class CustomSystemUnderDevelopment extends DefaultSystemUnderDevelopment
{
public CustomSystemUnderDevelopment( String... params )
{
}
public void onStartDocument(Document document)
{
//this method is called before GreenPepper execute a document
}
public void onEndDocument(Document document)
{
//this method is called after GreenPepper has executed the document
}
} |
