### Question:
DefaultAtlasContext implements AtlasContext, AtlasContextMXBean { @Override public AtlasSession createSession() throws AtlasException { init(); return doCreateSession(); } DefaultAtlasContext(URI atlasMappingUri);  DefaultAtlasContext(DefaultAtlasContextFactory factory, URI atlasMappingUri);  DefaultAtlasContext(DefaultAtlasContextFactory factory, AtlasMapping mapping);  DefaultAtlasContext(DefaultAtlasContextFactory factory,
            AtlasContextFactory.Format format, InputStream stream); @Override Audits processPreview(Mapping mapping); @Override void process(AtlasSession userSession); @Override void processValidation(AtlasSession userSession); @Override AtlasContextFactory getContextFactory(); AtlasMapping getMapping(); @Override AtlasSession createSession(); AtlasSession createSession(AtlasMapping mappingDefinition); Map<String, AtlasModule> getSourceModules(); void setSourceModules(Map<String, AtlasModule> sourceModules); Map<String, AtlasModule> getTargetModules(); void setTargetModules(Map<String, AtlasModule> targetModules); Map<String, LookupTable> getLookupTables(); void setLookupTables(Map<String, LookupTable> lookupTables); ObjectName getJmxObjectName(); @Override String getUuid(); @Override String getVersion(); @Override String getMappingName(); @Override String getMappingUri(); @Override String getClassName(); @Override String getThreadName(); @Override String toString(); ADMArchiveHandler getADMArchiveHandler(); static final String CONSTANTS_DOCUMENT_ID; static final String PROPERTIES_DOCUMENT_ID; }### Answer:
@Test public void testCreateSession() throws Exception { assertNotNull(context.createSession(mapping)); File file = Paths.get( "src" + File.separator + "test" + File.separator + "resources" + File.separator + "atlasmapping.json") .toFile(); DefaultAtlasContext ctx = new DefaultAtlasContext(file.toURI()); assertNotNull(ctx.createSession()); }
