### Question:
NamedClusterEmbedManager { public void passEmbeddedMetastoreKey( VariableSpace nameSpace, String embeddedMetastoreProviderKey ) { if ( nameSpace != null ) { if ( embeddedMetastoreProviderKey != null ) { nameSpace.setVariable( "vfs.hc.embeddedMetastoreKey", embeddedMetastoreProviderKey ); } } } NamedClusterEmbedManager( AbstractMeta meta, LogChannelInterface log ); void registerUrl( String urlString ); void clear(); boolean isAddedAnyClusters(); void addClusterToMeta( String clusterName ); void passEmbeddedMetastoreKey( VariableSpace nameSpace, String embeddedMetastoreProviderKey ); static final String NAMESPACE; }### Answer:
@Test public void testPassEmbeddedMetastoreKey() { Variables mockVariables = mock( Variables.class ); namedClusterEmbedManager.passEmbeddedMetastoreKey( mockVariables, "key" ); verify( mockVariables ).setVariable( anyString(), anyString() ); }
