Class SecurityProviderTestSupport

java.lang.Object

org.opensaml.security.SecurityProviderTestSupport

public class SecurityProviderTestSupport
extends Object

Testing utility class which providers various support functionality related to security providers and Java version, useful for testing cryptographic components.

One major feature is the ability to check and load the Bouncy Castle security provider for tests which require advanced crypto capabilities, and unload it afterwards, if it wasn't loaded originally. The goal of this is to preserve the pre-test condition of whether BC was originally loaded or not, so we don't muck with the environment of JVM in which the tests are running. For example, the JVM may actually have been configured with BC deliberately, so we don't want to unload it by mistake.
