Mule ESB - Mock Salesforce Interface
- 2. Mock ESB Endpoints using MUnit Mock an Mule ESB endpoint without real time need of an interface (during development time) Unit test your flows without & with real time interfaces Automate your unit test by testing with real time or without provider interfaces using Munit (from Jenkins) It is possible to mock SAP endpoint, JDBC Endpoint, Salesforce point and so on! Let us see an example of how to mock Salesforce
- 3. What is MUnit? A Beta-version testing framework from Mulesoft http://www.mulesoft.org/documentation/display/curre nt/Introduction+to+Testing+Mule#IntroductiontoTestin gMule-GoFurther This goes the extra mile than Functional Test Case - as Functional Test case requires real time interfaces for unit testing your flows Can switch to real time interface or use mock data easily using a flag from your CI tool Runs within Anypoint Studio and from Maven/Jenkins
- 4. Pre-requisites Anypoint studio 15 Jan 2015 release Mule CE or EE 3.5.2 runtime or 3.6.0 runtime MUnit 3.5.x runtime libraries/API MUnit interceptor API Salesforce credentials (having a SFDC account, user name/password and security token) Apache Maven installation Patience
- 5. Get MUnit Go to https://github.com/mulesoft/munit Download MUnit libraries Download Munit mule-interceptor-module Run pom.xml ($maven –X E clean insall, skip tests) on both the projects Jar files for Munit and mule-interceptor-modules should be generated by now Add these jar files (exclude sources) to Anypoint studio build class path
- 6. Salesforce Accounts Download Let us build a flow which downloads Accounts from Salesforce Triggered using Http endpoint (for example) SOQL query executed in Salesforce endpoint is SELECT ID, NAME, BILLINGCITY FROM ACCOUNT Salesforce returns all Accounts as an ArrayList<HashMap> Each HashMap contains SFDC Account information by having Name, ID or BILLINGCITY as key
- 8. Identify payload returned using Debugger
- 9. So far… We identified Salesforce returns ArrayList<HashMap> which contains Account information SOQL used is SELECT ID, NAME, BILLINGCITY FROM ACCOUNT We had built MUnit libraries for unit testing this
- 10. Unit testing approach Prepare Test Data to be returned by Salesforce Endpoint (mocked test data) Prepare Assertion data which will assert the Test Data Assert Test Data and Assertion Data
- 11. MUnit – Java based testing Overview Extend your Munit test case from FunctionalMUnitSuite (org.mule.munit.runner.functional.FunctionalMunitSuite) Define your flows to be loaded when Mule test case starts (like below): protected String getConfigResources() { return "SalesforceMock2.xml"; } Define whether to mock or use realtime interface // Return TRUE to mock endpoint, otherwise FALSE public boolean haveToMockMuleConnectors() { return true; }
- 12. MUnit – Java based testing Overview Following is XML file for the flow: <sfdc:config name="Salesforce" username="[email protected]" password=“aaaaaa" securityToken=“aaaaaa" doc:name="Salesforce"> <sfdc:connection-pooling-profile initialisationPolicy="INITIALISE_ONE" exhaustedAction="WHEN_EXHAUSTED_GROW"/> </sfdc:config> <flow name="SalesforceMockFlow"> <http:inbound-endpoint exchange-pattern="request- response" host="localhost" port="8081" doc:name="HTTP"/> <logger message="***** Before invoking Salesforce for Accounts *****" level="INFO" doc:name="Logger"/> <sfdc:query config-ref="Salesforce" query="select id, billingcity, name from Account" doc:name="Salesforce"/> <logger message="#[payload] ==> Payload type is: #[payload.getClass()]" level="INFO" doc:name="Logger"/> </flow>
- 13. Tell your MUnit java to mock To mock an endpoint (Salesforce), in your unit test case, first specify to mock an endpoint with a test mock data (like below): whenMessageProcessor("query"). ofNamespace("sfdc"). thenReturn( muleMessageWithPayload( accountsMockData ) ); Here, accountsMockData is the mock data payload Salesforce endpoint is <sfdc:query…> in flow XML having sfdc as namespae and query as processor name
- 14. Next steps We had told Munit to mock Salesforce endpoint with accountsMockData. So We need to prepare mock data for Accounts We need to prepare Assertion data for Accounts to Assert We need to Assert mock data and Assertion data so that your flow is fully functional for the test case Refer to complete test case java code
- 15. MUnit – Mock Salesforce Enpoint public class SalesforceMockTest extends FunctionalMunitSuite { @Test public void testSalesforceAccounts() throws Exception { // Step 1: Prepare Mock data for List of Salesforce Account objects using SFDCTestAccountPayloadGenerator SFDCTestAccountPayloadGenerator mockDataGenerator = new SFDCTestAccountPayloadGenerator(); ArrayList<HashMap<String,String>> accountsMockData = mockDataGenerator.getSalesforceAccountsTestData(); // Step 2: Register Mock data to Salesforce processor which will be returned (when invoked in the flow) whenMessageProcessor("query").ofNamespace("sfdc").thenReturn( muleMessageWithPayload( accountsMockData )); // Step 3: Invoke the flow (Salesforce endpoint is mocked now! - using a test event) MuleEvent resultEvent = runFlow( "SalesforceMockFlow", testEvent("Hello world!") ); ArrayList<HashMap<String,String>> flowResult = (ArrayList<HashMap<String,String>>) resultEvent.getMessage().getPayload(); // Step 4: resultEvent above has the Mocked Salesforce data. Now we need to assert it SFDCAssertAccountPayloadGenerator assertDataGenerator = new SFDCAssertAccountPayloadGenerator(); ArrayList<HashMap<String,String>> assertionData = assertDataGenerator.getAccountAssertionData(); assertEquals( assertionData, flowResult ); } } Note: getConfigResources() and haveToMockMuleConnectors() are omitted due to space constraints in this page
