DataTestSlice class final

Removes the beans of an application that a @DataTest leaves out, before any bean is created: its repositories and the other data beans stay, its services, controllers and other components go.

A bean of the application stays when one of the types it is registered under is a dataTypes (a repository is a DataRepository, an AuditorAware bean is one), when its class carries @EnableDataAuditing, or when it is one of the include types. Two more stay with them: the configuration object that makes a kept @Bean method's bean (a factory needs its instance, without the other @Bean methods of it), and, for an include type that is a configuration class, all its @Bean methods. Only the beans the application's modules declare are judged: the auto-configurations of the starters and what a test adds (@TestBean) are left alone.

The removal happens in the context, after its modules were read, so the conditions of the beans (@ConditionalOnProperty...) were decided with the whole application: a repository a property switches off stays off. A kept bean that needs a left out one fails the start as it always does: the report names the missing bean, and include it.

Spring (Java): the TypeExcludeFilter of @DataJdbcTest (DataJdbcTypeExcludeFilter) in the component scan of a slice; here the beans are listed by the generator at build time, so the filter works on their types.

Constructors

DataTestSlice(Iterable<BeanModule> modules, {Iterable<Type> include = const []})

A slice of the application whose beans modules declare, with the beans of the include types added.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

include → List<Type>

The beans added to the slice by the types of their classes.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

keptNames(Map<String, BeanDefinition<Object>> definitions) → Set<String>

The names, among definitions (the application's, by bean name), of the beans the slice keeps.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

postProcessBeanDefinitionRegistry(BeanDefinitionRegistry registry) → void

Adds, removes or replaces definitions in registry. Runs before every BeanFactoryPostProcessor.postProcessBeanFactory, this processor's own included.

override

postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) → void

Inspects or changes the definitions in beanFactory (scope, lazy, primary, ...). Avoid creating beans here: they would be created before the bean post-processors exist and miss their processing.

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

applicationDefinitions(Iterable<BeanModule> modules) → List<BeanDefinition<Object>>

Every definition of modules and of the modules they import, once.

isDataBean(BeanDefinition<Object> definition) → bool

Whether a bean registered as definition is a data bean: one of its types is a dataTypes or its class carries @EnableDataAuditing.

Constants

dataTypes → const Set<Type>

The types of the beans a slice keeps whatever the test says: the repositories, the entities' introspections, the database drivers, and the types the starter's auto-configuration looks up or replaces.
