1 Lab requirements and objectives

Time needed to complete this exercise: 1 hour

The scenario in this lab looks into the development, test and deployment of an application.

The application used in this scenario is the JKE Banking Application. This application is

available as a sample Application with Rational Collaborative Lifecycle Management.

1.1 What you should be able to do

At the end of this lab you should be able to:

Understand components, relationships and roadmap for setting up a DevOps Pipeline

Understand how to provision infrastructure using IBM Pure Application System

How to deploy an application using IBM Urbancode Deploy

How to create a „stub‟ in order to develop and test an application that is dependent

upon external services

Where to get additional information and demonstrations

1.2 Prerequisite knowledge

This lab assumes you‟re familiar with:

IBM WebSphere Application Server features and functionality

Application development and deployment basics

Basic knowledge of IBM Pure Application System features and purpose

1.3 About the sample application

The sample application used in this lab will leverage two components. The client side

application is dependent upon an external web service for stock quote information. In this

scenario we will be looking at how to leverage IBM Pure Application System and IBM

Urbancode Deploy to provision and test this application in an environment where the

engineers do not have access to the external web service.

1. JKE Stock Quote –Client side application „under development‟

2. External WebService – The client application will pull information from http://finance.google.com/finance/info?client=ig&q=NYSE:IBM

1.4 Lab requirements

These steps have been completed prior to the lab. More details are provided in the overall

workflow section and wiki:

2.2.2 Overall workflow

3 Activities

IMPACT 2014


3.1 Demo: Infrastructure Setup

IMPACT 2014


3.2 Demo: Project Initialization

IMPACT 2014


3.3 Activity: Deploying an Application

The following diagram provides an overview of both the provisioning and deployment steps.

This activity will walk through the area highlighted in blue which involves deploying the

application to a provisioned environment.

IMPACT 2014


3.3.1 Login to IBM Urbancode Deploy and view the JKE Application

Login to <IBM Urbancode Deploy URL> with user <USERID>, and password

<USERID>:

Navigate to Applications:

Select the JKE Application:

3.3.2 Locate the Environment which you will deploy the application into

IBM Urbancode Deploy provides an application centric view of the world. Looking at the

Environments tab of the application, you can see where and what versions of the application

is deployed.

An Environment has been pre-provisioned for each user using blueprints. Blueprints provide

the integration between IBM Urbancode Deploy and IBM Pure Application System. Each

user has an isolated testing environment. In this lab we will be deploying a new version of

the JKE application into your environment.

IMPACT 2014


Locate the environment for your userID. The environment name will be labeled testenv-

<USERID>.

3.3.3 Review your Application Environment

Click on your environment.

Note the resources that represent the deployed virtual machine, and application server that

you will be deploying the JKE Application into.

IMPACT 2014


3.3.4 Review the deployed Virtual System Instance in IBM Pure Application System

Open a new browser window and login to <IBM Pure Application System URL> with

<USERID> and <USERID>

Navigate to Workload Console

IMPACT 2014


Navigate to Virtual System

Locate your Virtual System Instance that was deployed from IBM Urbancode Deploy.

Review the details of the Virtual System Instance

Optionally take a snapshot of the Instance in this state

IMPACT 2014


Important: Write down the IP address of this machine as <ENV_HOST> and update

<JKE_URL> in the Variable table in section 2.1

Switch back to the IBM Urbancode Deploy browser window.

3.3.5 Deploy the JKE Application into your Environment in IBM Urbancode Deploy

Go back to the JKE Application view

IMPACT 2014


Run the Deploy Process

Select versions of the Application Components to deploy

IMPACT 2014


3.3.6 Monitor the Deployment process

Expand the steps to see the details

IMPACT 2014


When complete go back to the Application Environment and note the deployed application

IMPACT 2014


3.3.7 View the JKE Application

Open a browser to the <JKE_URL> that you previously wrote down when reviewing the

environment.

3.4 Activity: Creating Virtualized Test Service

In activity 3.3 you deployed and tested the JKE Application. This deployment process

included a step that configured the JKE Application to leverage a proxy server for the

external web service, which provided a generated response for the web service call. This

allows for the continuous development, integration and test of an application without

requiring all the dependent services to be available within the environment.

In this section we will dig a little deeper and have a look at how this web service stub can

be created using Rational Test Workbench and Rational Test Virtualization Server.

3.4.1 Connect to your Rational Test Workbench instance

Each participant in the workshop already has an instance of a Rational Test Workbench

workstation running in the IPAS environment. You will use a Virtual Network Connection

(VNC) client to access the workstation‟s desktop from your laptop. Use the <RTW IP

Address> from section 2.1 to access your instance.

Note. You can also view your RTW instance in IBM Pure Application System in a similar way

that you located your deployed test environment.

IMPACT 2014


From your workstation open the VNC Client

Enter the value for VNC Server in the following format: <RTW IP Address>:2 where

RTW IP Address is the address assigned to you per the table, above.

Click Connect

In the VNC Viewer – Authentication dialog, enter the password “Impact2014” and

click OK.

IMPACT 2014


Use the Full Screen mode.

NOTE: To exit Full Screen mode use Ctl-Alt-Shift-F

3.4.2 Open Rational Integration Tester

Double-click the IBM Rational Integration Tester launcher on the desktop to

launch Rational Integration Tester.

IMPACT 2014


In the project selection dialog, ensure the project JKERITVirtualizationTests is

selected and click OK,

3.4.3 Explore the Logical View model

The Logical View of the Architecture School perspective of Rational Integration Tester

enables you to visually model the relevant aspects of the system architecture. The new

Stock Quote feature of the JKE Banking application will leverage an API operation named

info provided by Google Finance. This relationship has been defined in the model for you.

Right-click the GoogleFinance HTTP connection in the diagram and select Physical

Resource. The settings of the physical web server model element define the host

and port of the server hosting the info service.

IMPACT 2014


Click the Test Transport button near the bottom of the Web Server dialog. Note

that since our IPAS environment does not have access to the internet, we are unable

to connect with the public server finance.google.com. This would normally stop our

testing but in the following sections, we will use Rational Integration Tester to create

a stub that will virtualize the Google service.

Dismiss the Transport Test and the Web Server dialogs by clicking OK twice.

IMPACT 2014


Double-click the info operation in the Logical View model. The Message Exchange

Pattern defines how the operation exchanges messages and the format of those

messages. For instance, the info operation employs a Request/Reply pattern as is

typical for web services. It uses the HTTP GET method over the GoogleFinance HTTP

connection and is rooted at the resource path “finance/info”. The request will

conform to the GoogleFinance REST schema that has been defined for you.

Click Cancel to dismiss the info operation dialog.

3.4.4 Create a Stub

You will now create a virtualized service or “stub” using the model. The creation of artifacts

such as stubs and tests is done in the Test Factory perspective.

Click the Test Factory perspective button on the toolbar.

IMPACT 2014


In the Test Factory perspective, right-click the info operation in the hierarchy

and select New > Stubs > Stub using MEP.

Name the stub <USERID>_stockQuote where <USERID>is the username

assigned to you in the table in section 2.1.

Rational Integration Tester stubs provide many powerful options that enable you to

develop anything from very simple stubs that simply reply with a fixed response

message to complex stubs that maintain state and respond dynamically based on the

request data. Stubs can even respond to requests that meet a certain criteria while

passing other requests on to a live service using a feature called “Sift and Pass-

through”. Because of the very limited time available in this workshop, you will

create a simple stub that replies with a static response.

Click on the Output tab in the middle of the Stub properties view. Since the

model in the Logical View did not define a schema for the response, it defaults

to a blank text string.

A simple way to define the response is to paste a sample of the response data

into the text field and let Rational Integration Tester format it for you.

Minimize IBM Rational Integration Tester so you can see the desktop.

Double-click the SampleResponse.txt text file to open it in KWrite – a text

editor.

IMPACT 2014


Select the entire contents of the file (Ctrl-A) and copy it to the clipboard

(Ctrl-C). Close the KWrite editor.

Click Rational Integration Tester on the taskbar to maximize it.

Double-click on the text (String) node in the message area to open the field

editor.

IMPACT 2014


Right-click in the text area on the Value tab and select Paste. Click OK to

close the Field Editor.

Rational Integration Tester immediately recognizes the text content as JSON

(JavaScript Object Notation) data and displays it in a name-value pair format.

This makes the data much easier to read for a user and makes each field

value accessible for substitution from variables, data files, database entries or

even the results of custom code calculations.

Save the stub.

3.4.5 Deploy the Stub to Rational Test Control Panel

Stubs can be executed directly from Rational Integration Tester. This is very useful when

you are first developing and testing stubs, but once you are ready to share your stub with

another tester, your entire team or even the entire enterprise, you can publish that stub to

the Rational Test Virtualization Server.

IMPACT 2014


Right-click the info operation in the navigator and select Publish Stubs.

Accept the defaults in the Publish Stubs dialog and click Publish. When

publishing is complete, click OK.

Minimize Rational Integration Tester so you can see the desktop.

Double-click the Link to Rational Test Control Panel launcher on the

desktop to open the Rational Test Control Panel component of Rational Test

Virtualization Server. The Rational Test Control Panel is the control interface

for all of the components of Rational Test Virtualization Server.

Log in with username “admin” and password “admin”.

On the home page, click the VIE (Virtualized Integration Environment)

image.

Select the default_domain domain and the DEV environment and click

View Dashboard. On the dashboard you will see all of the operations in all

the service components for the environment.

IMPACT 2014


Click the green plus sign next to the info operation.

From this dialog, you are able to start any version of any stub of the info operation

that has been published to the Rational Test Control Panel. The list of stubs you see

will vary as other lab participants finish deploying their stubs.

Click Cancel to exit the dialog without starting a stub. We have already started a

stub for the Google Finance service that we will use in the next activity.

3.5 Demo: Continuous Integration and Deployment

IMPACT 2014


4 What you did in this exercise

4.1 Content reviewed

You reviewed an overall scenario for Continuous Integration, Test and Deployment of JKE

Application. You reviewed the relationship between IBM Urbancode Deploy and IBM Pure

Application System for deployment, and how Test Virtualization can be used to test

applications that are dependent upon external services.

4.2 Activities Completed

Used IBM Urbancode Deploy to deploy an application to an environment that had been

provisioned on IBM Pure Application System. Created a „stub‟ to mock out a call to an

external WebService to facilitate development of test of an application when those services

may not be available or desirable to call directly.
