= `@ContextCustomizerFactories`

`@ContextCustomizerFactories` is used to register `ContextCustomizerFactory`
implementations for a particular test class, its subclasses, and its nested classes. If
you wish to register a factory globally, you should register it via the automatic
discovery mechanism described in
xref:testing/testcontext-framework/ctx-management/context-customizers.adoc[`ContextCustomizerFactory` Configuration].

The following example shows how to register two `ContextCustomizerFactory` implementations:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@ContextConfiguration
	@ContextCustomizerFactories({CustomContextCustomizerFactory.class, AnotherContextCustomizerFactory.class}) // <1>
	class CustomContextCustomizerFactoryTests {
		// class body...
	}
----
<1> Register two `ContextCustomizerFactory` implementations.

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@ContextConfiguration
	@ContextCustomizerFactories([CustomContextCustomizerFactory::class, AnotherContextCustomizerFactory::class]) // <1>
	class CustomContextCustomizerFactoryTests {
		// class body...
	}
----
<1> Register two `ContextCustomizerFactory` implementations.

By default, `@ContextCustomizerFactories` provides support for inheriting factories from
superclasses or enclosing classes. See
xref:testing/testcontext-framework/support-classes.adoc#testcontext-junit-jupiter-nested-test-configuration[`@Nested` test class configuration] and the
{spring-framework-api}/test/context/ContextCustomizerFactories.html[`@ContextCustomizerFactories`
javadoc] for an example and further details.
