CustomWare Asia Pacific Pty Ltd All Rights Reserved Issues with Integration Projects Resources Changing requirements Platform upgrading Re-deployment Partner integration and testing

CustomWare Asia Pacific Pty Ltd All Rights Reserved Issues with Resources Too often, key individuals play an important role in a project and do not hand over enough knowledge After key resources move on, integration code needs to be maintained Deployment staff whom do not write code, need to have confidence code they are supporting works Project Managers need to have confidence when working with external consultants

CustomWare Asia Pacific Pty Ltd All Rights Reserved Issues with Upgrading webMethods, like all integration vendors, upgrades the version of their platform every months. Falling too far behind means unsupported code. Why isn’t upgrading easy? How do you currently control your upgrades? Can you immediately and accurately determine if your code works on a new platform, or do you require expensive external assistance? How will the next JVM upgrade affect your project? Upgrading should not be guesswork

CustomWare Asia Pacific Pty Ltd All Rights Reserved Issues with Re-deployment If an integration project is successful and needs to be rolled out and scaled to meet business demand, how easy is it for the system administrators to reconfigure it with confidence? When moving between platforms, how thorough are your integration projects tested? When new features are added, how can you tell that nothing has been accidentally broken? How do we add new trading partners without spending too much time ‘hand holding’?

CustomWare Asia Pacific Pty Ltd All Rights Reserved A Controlled Integration Strategy The cornerstone to any successful integration strategy/competency centre is control What is control? –Controlling standards & best practices (GEAR, CCDM) –Controlling technology (Using open standards) –Controlling quality (Strong, Robust & Visible testing techniques)

CustomWare Asia Pacific Pty Ltd All Rights Reserved A Controlled Approach Each project we deliver is a product Integration projects should endure the same test techniques as any other product Prevention is better than a cure WmUnit is the cornerstone of the development and deployment cycles of a project

CustomWare Asia Pacific Pty Ltd All Rights Reserved Focus on integration quality: Testing Significantly reduce the risk of change by introducing a testing regime Relate specifications to code via tests Develop trust in your code by creation of automated tests Support the later maintenance effort by providing a base of automated tests

CustomWare Asia Pacific Pty Ltd All Rights Reserved Goals of WmUnit Make testing on the webMethods platform: –Easier (no cumbersome custom developed test harnesses) –Faster (leave developers in a familiar area) – Allow the inclusion of existing test harness code with minimal alteration –In container testing rather than external HTTP tools –Provide a level of reporting on the status of test cases success/failure

CustomWare Asia Pacific Pty Ltd All Rights Reserved Writing a WmUnit test case Uses familiar programming constructs –Creating a service –Selecting a service specification –Setting of inputs/expected outputs in a map step or via restore pipeline from file –Invoking service to test and utility “assert” services

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 1 Create a service –Mirror directory structure of package to be tested –Name should be descriptive of the type of test

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 2 Set service specification to TestCase

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 3 Include test case description (optional)

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 4 Input/Expected output(s)

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 5 Invoke service to test, map output, cleanup

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 6 Invoke one of the utility assert services

CustomWare Asia Pacific Pty Ltd All Rights Reserved From scratch - step 7 Can map error message (optional) %wmTestResult/isValid%=="false"

CustomWare Asia Pacific Pty Ltd All Rights Reserved Running by hand Can run individually by hand with the developer –Test cases are just services after all

CustomWare Asia Pacific Pty Ltd All Rights Reserved 2 Steps to creating more tests Update the values in the first map step

CustomWare Asia Pacific Pty Ltd All Rights Reserved Complementary tools WmUnit can be complimented by the following tools: –JMeter and Pure test For hooking into WmUnit to create load testing –JUnit For included jarred up code, pure java (non- webMethods code) –Other out of container test harnesses For invoking as part of a batch script or command line load test

CustomWare Asia Pacific Pty Ltd All Rights Reserved WmUnit provides test runner which is externally invokable and generally a much nicer way to group together test logic –Set of end to end tests –Sets of mapping specification tests –Developer unit tests Complementary tools

CustomWare Asia Pacific Pty Ltd All Rights Reserved Why WmUnit? Less cumbersome than writing: –Java code –Jmeter, puretest scripts (or HTTP Unit type code) In container –All Integration Server functionality available Tailored to WebMethods –Assert services to make life easier –Write in flow, java, c/c++ etc Existing solution –No need to waste resources on writing a test engine Can use existing test harnesses that developers have written Runnable in developer individually if desired No chatty network calls required Invoked via web interface Can be used for end to end, stress testing and down to low level unit testing

CustomWare Asia Pacific Pty Ltd All Rights Reserved Managing your integration quality WmUnit allows history of results to be kept –Allows viewing of project test case growth –success/failure ratio to be examined –Number of test runs performed during development

CustomWare Asia Pacific Pty Ltd All Rights Reserved Test History Over time Typical project –Overall umber of tests increase over time –Change may break existing tests –Should be mostly green (existing tests)

CustomWare Asia Pacific Pty Ltd All Rights Reserved Test History Over time Also a typical scenario: –Set of acceptance criteria –Specifications are met –Test first development
