INTRODUCTION Azure is an open and flexible cloud platform that enables you to quickly build, deploy and manage applications across a global network of Microsoft-managed datacenters. You can build applications using any language, tool or framework. And you can integrate your public cloud applications with your existing IT environment. You can use the Virtual Machines as a testing environment on their cloud networks to configure AppLoader. PURPOSE We are convinced that AppLoader will work in your environment and we are here to convince you! This guide will explain how to create a new Windows Azure Storage Account and Virtual Machine using the Windows Azure portal. After the machine is provisioned, you will connect to the virtual machine using Remote Desktop Protocol (RDP). Once connected, you will be able to perform tasks on the virtual machine just as you would for an on premise machine. You will learn how to build a test scenario, send it to the controller, and set up a load test with 5, 10, 20,50 or as many rusers as you want. Also you will be able to run multiple Load Tests with multiple Injectors by cloning the Injector.

INSTALLING APPLOADER SUITE ON WINDOWS AZURE PREREQUISITES The AppLoader Suite consists of three components AppLoader Controller, Injector and ScenarioBuilder. Together, they comprise NRG Global s easy-to-use, script-free load testing solution. AppLoader works with Terminal Services from Microsoft to generate multiple users simultaneously interacting with an application from one Windows Server. Install the AppLoader components in the following manner: 1. AppLoader Controller Install on a Windows Server. Installation sets up the Controller which manages, drives, and monitors load tests in real-time, and provides test analyses through summarized and detailed reports and graphs. 2. Injector Install on a Windows server. Installation sets up the Injector which hosts multiple users performing real life Scenarios on the application under test. Make sure that AppLoader Controller is already installed before installing the Injector. 3. ScenarioBuilder Install on a Windows Server (same machine or clone of the Injector Server). This easy-to-use tool facilitates the creation of a wide range of test Scenarios for load testing. Start by downloading the AppLoader installation package from the Downloads page on the NRG Global website.. Save the apploader_suite_setup.zip file in the first VM (nrgvmapploader) and extract the contents of the file to a new folder. You will find a separate folder for each of the components; AppLoader, Injector and ScenarioBuilder. Within each folder is a setup file for its respective component.

INSTALL MICROSOFT.NET FRAMEWORK 3.5 After installing the AppLader Contoller, the Injector and ScenarioBuilder. Perform the following steps in both VMs. 1. Open the Server Manager. Click on Add Features. 2. Check.NET Framework 3.5.1 Features. Click Next 2014 NRG Global, Inc. All rights reserved. Page 29

GETTING STARTED WITH APPLOADER CREATE AND EXECUTE A LOAD TEST The communication flow for AppLoader is: AppLoader Controller Injector rusermanager VStation VStation - The VStation is the component that is installed under each ruser. The VStation is what will perform the playback of the scenario during the load test, without it the ruser will not perform the Scenario playback. The VStation is programmed to start automatically once the ruser is logged in. rusers - The real user accounts which exist in the Windows environment and are administered through AppLoader. rusermanager - This is the component of ScenarioBuilder that is used to oversee the rusers during Scenario playback. Also, it is better to create your scripts inside the rusermanager. Before launching the controller and starting load testing, make sure to start the Injector and the VSation. You can start them from the Injector s folder in program menu. Launch AppLoader Controller: After installing AppLoader, a shortcut will be created on the desktop. Launch the AppLoader Controller web interface to manage, run, and analyze your tests. 1. Double-click the AppLoader shortcut to launch the AppLoader Controller in your default browser. You can also launch the AppLoader Controller by entering IP address of the Server (or localhost ) and Web Server Port number into the address bar of a web browser. 2014 NRG Global, Inc. All rights reserved. Page 33

2. Log in to AppLoader (User Name: admin / Password: admin) You ll notice the Injector has registered itself with the AppLoader Controller. If the Injector was not registered with the AppLoader Controller, turn off the Firewalls for both VMs (nrgvmapploader and nrgvminjector). Define rusers: Defining rusers is the first step in preparing a load test. Once rusers are defined, this step does not have to be repeated, unless rusers are deleted. Define rusers only applies to AppLoader suite if it is installed onto a server, if the AppLoader suite is installed on a PC, rusers cannot be defined. Check the Injector that you want to define rusers for. Then click the Define rusers the menu bar. Injector rusers form opens; button in 2014 NRG Global, Inc. All rights reserved. Page 34

Mode: Select the type of ruser accounts to create from the drop down menu (Incremental; From CSV File, One ruser). User Name: Provide a generic user name for ruser accounts. AppLoader will add a sequential numeric suffix to make each account unique (e.g. ruser001, ruser002, ruser003, etc ). User names must be compliant with the Windows server requirements. Recommended value: ruser) Password: Enter a password for the ruser accounts. Password must be compliant with the Windows server requirements. Recommended value: Password123). Click Submit to issue the Define rusers command. If rusers are not created prior to launching a test, ruser Manager will automatically create rusers for the test. Start rusers: The next step in the process is to Start rusers. This process launches the rusermanager on the Injector and initiates the ruser logins. Start rusers only applies to AppLoader suite if it is installed onto a Server. Click the Start rusers button. The Start rusers window pops up; # Of Users: Specify the number of users to start on the selected Injector. Launch Delay: Specify a launch delay in seconds. The system waits this amount of time after starting each ruser. Click Submit to start rusers. Started rusers can be viewed in the Real Time Results page of the Controller. 2014 NRG Global, Inc. All rights reserved. Page 35

Once you start the rusers, ruser Manager will automatically start on the second VM (nrgvminjector). The rusermanager can be viewed throughout the test process, from the starting of rusers through the complete execution of the test. It can be minimized or maximized on the Injector as the test is in progress. However closing the rusermanager during the test would end Scenario playback and disrupt the test. You can view, manage, delete, stop, and disconnect rusers from AppLoader Controller and delete them from Windows Server. 2014 NRG Global, Inc. All rights reserved. Page 36

Create A Scenario Using ScenarioBuilder Inside The rusermanager: In this part, you should create your scenario with ScenarioBuilder. Scenarios are the action sequences which emulate your real user activity within your application. Creating your first scenario is simple. If you know how to use your application, then you know how to script a scenario with ScenarioBuilder. For this guide, we creates three separate scenarios that are related to each other: Login, Search and Log off. The second scenario (Search)can include multiple scripts. You can create your own scenario. After you finish your scenario, do the following steps: 1. Playback scenario (as many times as necessary) to ensure that it performs as expected. 2. Set reference time (in execution report window after a successful scenario playback). 3. Save scenario. 4. Send it to Controller. You will see a dialog box indicating Send successful upon completion. To make sure that the scenario will be send to the correct controller, you can follow these steps: 1. Click on View in ScenarioBuilder toolbar 2. Go to Option 3. Click on Base 4. If you couldn t find the Controller address ( In this case, the IP address of the Controller is the Internal IP address of the first VM (nrgvmapploader: 100.75.254.35 ), click on Add button to enter your Apploader Controller information. 2014 NRG Global, Inc. All rights reserved. Page 37

5. Click on Test button to test the connection between ScenarioBuilder and Controller. 5. Close or minimize ScenarioBuilder. Please refer to the ScenarioBuilder User Guide for more information. You can download it from here. Click here for the complete ScenarioBuilder video tutorial series. 2014 NRG Global, Inc. All rights reserved. Page 38

Manage Tests: Click the Manage Tests button to design a Test Plan. The Manage Tests page defaults to the Test Plans List view; it is empty if you have not created any Test Plans yet. Click the Create New Test Plan button in the menu bar. The Test Plan form opens; The below image shows how the Test Plan form looks upon opening. Fill out the required information in each field. Here are the quick steps: 1. Enter a name for the new Test Plan. 2. Attach a Template for backend monitoring (optional). 2014 NRG Global, Inc. All rights reserved. Page 39

3. Provide a Steady State Time in minutes that the user will actively play scenario. As you login (Open) and log off (Close) a website or an application only once, it is better to set value 0 for the Steady State Time filed when you create the Login and Log off Test Plans. 4. Ramp-up Time and Users/Minute will be automatically calculated based on the Test Plan details provided (these fields cannot be edited manually). 5. Select the Injector. There is only one Injector that can be selected from Injector field in TestPlan Details section. 6. Select the scenario that should be tested. 7. Enter the number of rusers to play the selected Scenario on the selected Injector. 8. Enter the time, in seconds, that each ruser waits before playing the Scenario. A Delay value of "0" results in all rusers beginning simultaneously. A Delay value of "5" results in each ruser beginning 5 second after the previous. A Delay value of 30 will be an appropriate value for the Login and Log off Test Plans. 9. As soon as you select the scenario from the Scenario field in the TestPlan Details, AppLoader automatically calculates the test duration and iterations and populates those fields on the form. All the information about that scenario, such as the CSV Files, etc. will be set automatically. Although you can change them, it is not necessary. 2014 NRG Global, Inc. All rights reserved. Page 40

For more information on filling out these fields please refer to AppLoader UserGuide document. You can download it from here. After completing all of the applicable sections of the Test Plan, click the Save Details window to save your Test Plan. The following message will appear: button above the Click Yes to open the Execution Plan form for viewing and editing; The Execution Plan will show the ruser name, Host, assigned Scenario, assigned number of Iterations, Start Delay, CSV file, and Assigned CSV Rows. 2014 NRG Global, Inc.

Close the Execution Plan window to continue. The following message will appear: If you have only one scenario that you want to run, click Yes to run your test otherwise click No to exit without running. If you clicked Yes the following window opens. Specify a name for your load test and click Submit. AppLoader shifts to the Real Time Results page automatically after submitting the test. 2014 NRG Global, Inc. All rights reserved. Page 42

For this guide, we create three scenarios. Therefore, we have to create three Test Plans for each of them. For Load Testing, we need to create an execution flow. Create An Execution Flow: With Execution Flows you are able to cue up a series of Test Plans to automatically play, one after the next. Click the Create New Execution Flow button in the menu bar. The Execution Flow Schedule form opens; The below image shows how the Execution Flow Schedule page looks upon opening. Fill out the required information in each field. Here are the quick steps: 1. Enter a name for the Execution Flow (avoid special characters). 2. Provide an optional description to help identify this Execution Flow. 3. Double-click on, the Available Test Plans pane the Test Plans you wish to include in your Execution Flow. 4. Use this feature to establish whether or not to execute tests on the rusers that failed in the previous test. 2014 NRG Global, Inc. All rights reserved. Page 43
