I'm developing a grails plugin, but when I try to create an integration test for a service I'm getting this error
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'aService': Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'transactionManager' is defined

how can I solve it?
I believe that this can occur if you've uninstalled Hibernate and you don't specify another transaction manager. Grails services by default are transactional and Hibernate is what manages that transaction. If you're not using Hibernate you can set your service to be non-transactional with def transactional = false
