### Question:
Server implements ServerConfigurationProvider, Closable { public Workspaces getWorkspaces() { if (workspaces == null) { workspaces = new Workspaces(this); } return workspaces; } Server(final Launcher launcher, final TaskListener taskListener, final String url, final String username, final String password);  Server(final Launcher launcher, final TaskListener taskListener, final String url, final String username, final String password, final WebProxySettings webProxySettings, final ExtraSettings extraSettings); static Server create(final Launcher launcher, final TaskListener taskListener, final String url, final StandardUsernamePasswordCredentials credentials, final WebProxySettings webProxySettings, final ExtraSettings extraSettings); Project getProject(String projectPath); Workspaces getWorkspaces(); @SuppressFBWarnings(value = { "DC_DOUBLECHECK", "IS2_INCONSISTENT_SYNC"}, justification = "Only synchronize if not null") MockableVersionControlClient getVersionControlClient(); HttpClient getHttpClient(); T execute(final Callable<T, E> callable); String getUrl(); String getUserName(); String getUserPassword(); Launcher getLauncher(); WebProxySettings getWebProxySettings(); ExtraSettings getExtraSettings(); TaskListener getListener(); synchronized void close(); IIdentityManagementService createIdentityManagementService();  }### Answer:
@Test public void assertGetWorkspacesReturnSameObject() throws IOException { Server server = createServer(); assertNotNull("Workspaces object can not be null", server.getWorkspaces()); assertSame("getWorkspaces() returned different objects", server.getWorkspaces(), server.getWorkspaces()); }
