Interface ApplicationContextAssertProvider<C extends ApplicationContext>

Type Parameters:

C - the application context type

All Superinterfaces:

ApplicationContext, ApplicationEventPublisher, org.assertj.core.api.AssertProvider<ApplicationContextAssert<C>>, AutoCloseable, BeanFactory, Closeable, EnvironmentCapable, HierarchicalBeanFactory, ListableBeanFactory, MessageSource, ResourceLoader, ResourcePatternResolver

All Known Subinterfaces:

AssertableApplicationContext, AssertableReactiveWebApplicationContext, AssertableWebApplicationContext

public interface ApplicationContextAssertProvider<C extends ApplicationContext>
extends ApplicationContext, org.assertj.core.api.AssertProvider<ApplicationContextAssert<C>>, Closeable

An ApplicationContext that additionally supports AssertJ style assertions. Can be used to decorate an existing application context or an application context that failed to start.

Assertions can be applied using the standard AssertJ assertThat(...) style (see ApplicationContextAssert for a complete list). For example:

 assertThat(applicationContext).hasSingleBean(MyBean.class);
 

If the original ApplicationContext is needed for any reason the getSourceApplicationContext() method can be used.

Any ApplicationContext method called on a context that has failed to start will throw an IllegalStateException.

Since:

2.0.0

Method Detail

assertThat

@Deprecated
ApplicationContextAssert<C> assertThat()

Deprecated. to prevent accidental use. Prefer standard AssertJ assertThat(context)... calls instead.

Return an assert for AspectJ.

Specified by:

assertThat in interface org.assertj.core.api.AssertProvider<ApplicationContextAssert<C extends ApplicationContext>>

Returns:

an AspectJ assert

getSourceApplicationContext

C getSourceApplicationContext()

Return the original source ApplicationContext.

Returns:

the source application context

Throws:

IllegalStateException - if the source context failed to start

getSourceApplicationContext

<T extends C> T getSourceApplicationContext(Class<T> requiredType)

Return the original source ApplicationContext, casting it to the requested type.

Type Parameters:

T - the context type

Parameters:

requiredType - the required context type

Returns:

the source application context

Throws:

IllegalStateException - if the source context failed to start

getStartupFailure

Throwable getStartupFailure()

Return the failure that caused application context to fail or null if the context started without issue.

Returns:

the startup failure or null

close

void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

get

static <T extends ApplicationContextAssertProvider<C>,C extends ApplicationContext> T get(Class<T> type,
                                                                                          Class<? extends C> contextType,
                                                                                          Supplier<? extends C> contextSupplier)

Factory method to create a new ApplicationContextAssertProvider instance.

Type Parameters:

T - the assert provider type

C - the context type

Parameters:

type - the type of ApplicationContextAssertProvider required (must be an interface)

contextType - the type of ApplicationContext being managed (must be an interface)

contextSupplier - a supplier that will either return a fully configured ApplicationContext or throw an exception if the context fails to start.

Returns:

a ApplicationContextAssertProvider instance
