### Question:
SequenceDeployer extends AbstractSynapseArtifactDeployer { @Override public String deploySynapseArtifact(OMElement artifactConfig, String fileName, Properties properties) { CustomLogSetter.getInstance().setLogAppender(customLogContent); if (log.isDebugEnabled()) { log.debug("Sequence Deployment from file : " + fileName + " : Started"); } try { MediatorFactoryFinder.getInstance().setSynapseLibraryMap(getSynapseConfiguration().getSynapseLibraries()); Mediator m = MediatorFactoryFinder.getInstance().getMediator( artifactConfig, properties); if (m instanceof SequenceMediator) { SequenceMediator seq = (SequenceMediator) m; if (getSynapseConfiguration().getDefinedSequences().get(seq.getName()) != null) { handleSynapseArtifactDeploymentError("Sequence named : " + seq.getName() + " already exists."); } seq.setArtifactContainerName(customLogContent); seq.setFileName((new File(fileName)).getName()); if (log.isDebugEnabled()) { log.debug("Sequence named '" + seq.getName() + "' has been built from the file " + fileName); } seq.init(getSynapseEnvironment()); if (log.isDebugEnabled()) { log.debug("Initialized the sequence : " + seq.getName()); } getSynapseConfiguration().addSequence(seq.getName(), seq); if (log.isDebugEnabled()) { log.debug("Sequence Deployment from file : " + fileName + " : Completed"); } log.info("Sequence named '" + seq.getName() + "' has been deployed from file : " + fileName); return seq.getName(); } else { handleSynapseArtifactDeploymentError("Sequence Deployment Failed. " + "The artifact described in the file " + fileName + " is not a Sequence"); } } catch (Exception e) { handleSynapseArtifactDeploymentError( "Sequence Deployment from the file : " + fileName + " : Failed.", e); } return null; }  @Override String deploySynapseArtifact(OMElement artifactConfig, String fileName,
                                        Properties properties); @Override String updateSynapseArtifact(OMElement artifactConfig, String fileName,
                                        String existingArtifactName, Properties properties); @Override void undeploySynapseArtifact(String artifactName); @Override void restoreSynapseArtifact(String artifactName);  }### Answer:
@Test public void testDeploy() throws Exception { String inputXML = "<sequence name=\"TestSequence\" xmlns=\"http: + " <log/>" + " </sequence>"; OMElement inputElement = AXIOMUtil.stringToOM(inputXML); SequenceDeployer sequenceDeployer = new SequenceDeployer(); SynapseConfiguration synapseConfiguration = new SynapseConfiguration(); AxisConfiguration axisConfiguration = synapseConfiguration.getAxisConfiguration(); ConfigurationContext cfgCtx = new ConfigurationContext(axisConfiguration); SynapseEnvironment synapseEnvironment = new Axis2SynapseEnvironment(cfgCtx, synapseConfiguration); axisConfiguration.addParameter(new Parameter(SynapseConstants.SYNAPSE_ENV, synapseEnvironment)); axisConfiguration.addParameter(new Parameter(SynapseConstants.SYNAPSE_CONFIG, synapseConfiguration)); cfgCtx.setAxisConfiguration(axisConfiguration); sequenceDeployer.init(cfgCtx); String response = sequenceDeployer.deploySynapseArtifact(inputElement, "sampleFile", null); Assert.assertEquals("Sequence not deployed!", "TestSequence", response); }
