Interface TestContext

All Superinterfaces:

AttributeAccessor, Serializable

All Known Implementing Classes:

DefaultTestContext

public interface TestContext
extends AttributeAccessor, Serializable

TestContext encapsulates the context in which a test is executed, agnostic of the actual testing framework in use.

As of Spring Framework 5.0, concrete implementations are highly encouraged to implement a copy constructor in order to allow the immutable state and attributes of a TestContext to be used as a template for additional contexts created for parallel test execution. The copy constructor must accept a single argument of the type of the concrete implementation. Any implementation that does not provide a copy constructor will likely fail in an environment that executes tests concurrently.

Since:

2.5

Method Detail

getApplicationContext

ApplicationContext getApplicationContext()

Get the application context for this test context, possibly cached.

Implementations of this method are responsible for loading the application context if the corresponding context has not already been loaded, potentially caching the context as well.

Returns:

the application context

Throws:

IllegalStateException - if an error occurs while retrieving the application context

getTestClass

Class<?> getTestClass()

Get the test class for this test context.

Returns:

the test class (never null)

getTestInstance

Object getTestInstance()

Get the current test instance for this test context.

Note: this is a mutable property.

Returns:

the current test instance (may be null)

See Also:

updateState(Object, Method, Throwable)

getTestMethod

Method getTestMethod()

Get the current test method for this test context.

Note: this is a mutable property.

Returns:

the current test method

See Also:

updateState(Object, Method, Throwable)

getTestException

@Nullable
Throwable getTestException()

Get the exception that was thrown during execution of the test method.

Note: this is a mutable property.

Returns:

the exception that was thrown, or null if no exception was thrown

See Also:

updateState(Object, Method, Throwable)

markApplicationContextDirty

void markApplicationContextDirty(@Nullable
                                 DirtiesContext.HierarchyMode hierarchyMode)

Call this method to signal that the application context associated with this test context is dirty and should be removed from the context cache.

Do this if a test has modified the context — for example, by modifying the state of a singleton bean, modifying the state of an embedded database, etc.

Parameters:

hierarchyMode - the context cache clearing mode to be applied if the context is part of a hierarchy (may be null)

updateState

void updateState(@Nullable
                 Object testInstance,
                 @Nullable
                 Method testMethod,
                 @Nullable
                 Throwable testException)

Update this test context to reflect the state of the currently executing test.

Caution: concurrent invocations of this method might not be thread-safe, depending on the underlying implementation.

Parameters:

testInstance - the current test instance (may be null)

testMethod - the current test method (may be null)

testException - the exception that was thrown in the test method, or null if no exception was thrown
