| |
| O `org.apache.openejb.junit.ApplicationComposer` é o executor de testes JUnit modelado de acordo com a forma como fizemos testes internos no OpenEJB por anos (desde 2006). |
| Isto não envolve o escaneamento de toda a classpath. Se você quiser alguma coisa na aplicação, você deve construí-lo diretamente no seu testcase. |
| |
| Com o `ApplicationComposer` você pode fazer testes idênticos ao que o OpenEJB usa internamente, mas com dependência limitada do próprio OpenEJB. A principal dependência está no código |
| que é usado para construir as aplicações atuais: |
| |
| <dependency> |
| <groupId>org.apache.tomee</groupId> |
| <artifactId>openejb-core</artifactId> |
| <version>${openejb.version}</version> |
| </dependency> |
| |
| == Compondo um aplicativo |
| |
| A principal diferença para a API incorporada `EJBContainer` é construir o aplicativo no código de teste. Isso é feito com um ou mais métodos no caso de teste anotado |
| com `org.apache.openejb.testing.Module` usando o seguinte formato: |
| |
| @Module |
| public <return-value> <module-name>() { |
| |
| onde **module-name** é o nome que você deseja usar para esse módulo e **return-value** pode ser qualquer um dos deles: |
| |
| - java.lang.Class |
| - java.lang.Class[] |
| - org.apache.openejb.jee.EjbJar |
| - org.apache.openejb.jee.EnterpriseBean |
| - org.apache.openejb.jee.Application |
| - org.apache.openejb.jee.Connector |
| - org.apache.openejb.jee.Beans |
| - org.apache.openejb.jee.jpa.unit.Persistence |
| - org.apache.openejb.jee.jpa.unit.PersistenceUnit |
| |

| Usado em um testcase atual, pode ser assim: |
