The document discusses how to use Visual Studio Team System to test web applications for performance problems. It covers creating and running web tests to simulate user loads on a web application. Validation and extraction rules are used to verify test results. Load tests can also be created to test applications under different user loads and connection models. Load Test Analyzer is used to interpret load test results and identify bottlenecks or errors. Demonstrations are provided on creating, running and verifying web and load tests.
Cloud vendor lock-in is one of
the major problems in cloud computing where the
customer is locked to a particular vendor so that it
will be difficult to migrate from one cloud to the
other. The problem is that once an app has been
developed based on a particular cloud service
provider’s API that apps is bound to that provider
as a result of which migration from one cloud to
the other becomes more complex because of
changes in architectures of different cloud service
vendors[2]. The problem can be solved by
providing a standardized way of interacting with
cloud service providers taking many factors into
consideration and by isolating each individual
module involved in the cloud service provider’s
API and bringing out the common things and
uniting them together so that in future any CSP
will have to obey that specific standards and build
their APIs without the need of creating a new
standard that makes migration from/to that CSP
complex.
JMeter is an Open source tool. Can load and performance test many different server types: Web - HTTP, HTTPS, SOAP, Database via JDBC, LDAP, JMS, Mail - POP3(S) and IMAP(S).
User friendly GUI Design compare to other tools.

A NOVEL METHOD TO TEST DEPENDABLE COMPOSED SERVICE COMPONENTSIJCNCJournal
Assessing Web service systems performance and their dependability are crucial for the development of
today’s applications. Testing the performance and Fault Tolerance Mechanisms (FTMs) of composed
service components is hard to be measured at design time due to service instability is often caused by the
nature of the network conditions. Using a real internet environment for testing systems is difficult to set up
and control. We have introduced a fault injection toolkit that emulates a WAN within a LAN environment
between composed service components and offers full control over the emulated environment in addition to
the capability to inject network-related faults and application specific faults. The toolkit also generates
background workloads on the system under test so as to produce more realistic results. We describe an
experiment that has been performed to examine the impact of fault tolerance protocols deployed at a
service client by using our toolkit system.

Top 20 LoadRunner Interview Questions and Answers in 2023.pdfAnanthReddy38
What is LoadRunner?
LoadRunner is a performance testing tool developed by Micro Focus. It allows testers to measure and analyze system performance under various load conditions.
What are the components of LoadRunner?
LoadRunner consists of three main components: Virtual User Generator (VuGen), Controller, and Analysis.
What is VuGen in LoadRunner?
VuGen (Virtual User Generator) is a tool in LoadRunner used for recording and scripting user actions on the application under test.
What is the purpose of the LoadRunner Controller?
The LoadRunner Controller is used to configure and manage load tests. It allows you to define scenarios, allocate resources, and monitor test execution.
Wading through treacle? Escape the integration syrup with contract testsStefan Smith
How can teams that develop collaborating services get features out quickly when they face time-consuming integration testing?
Contract tests capture the agreements between services and consumers. They provide fast, lightweight verification of service behaviour, giving teams early feedback about oncoming danger.

What Are Validation and Extraction Rules?
Demonstration: How to Verify Web Tests
Demonstration: How to Create and Run a Web
Test
4
5. What Are Web Tests?
Web tests are used to test the functionality of
Web applications.
Web tests consist of a series of HTTP requests.
Requests are replayed by an agent, and not a Web browser.
The Web application being tested can be any
HTTP application, and not just an ASP.NET
application. It can also be based on the new
AJAX support.
Web tests can be run in parallel to create load
tests:
A load test simulates multiple users opening simultaneous connections
to a server and making multiple HTTP requests.
5
6. What Is the Importance of Web Tests?
Web applications are becoming increasingly
complex.
Many Web applications host business
critical functions.
Web applications must have both high
performance and be broadly scalable.
Consumers are expecting ever more
compelling and stable Web sites.
A single problem can lose the loyalty of millions of users.
6
7. How Web Tests Are Created
Recorded Web tests are:
Created by simply recording a browsing session.
Stored as XML.
Edited graphically in the Web Test Editor.
Coded Web tests are:
Generally created by converting a recorded Web test.
Stored as .NET Code (VB.NET or C#.)
Edited in a code editor.
Can easily access the full power of the .NET Framework.
Necessary for branching and looping.
7
8. How Web Tests Are Run
Web Tests can be triggered in the following ways:
• Web Test Editor
• Test View Window
• Test Manager Window
• Command Line
• Using the Web Test Viewer:
Web Test Viewer shows an overview of the status of individual requests.
View the details of each request in the Web test and the resulting
response to those requests.
8
9. What Are Validation and Extraction Rules?
Validation rules help verify if the Web
application is functioning properly. They
verify the:
Existence of text, tags, or attributes on the page returned by a
Web request
Time it takes a request to finish
Existence of form fields and their values
Extraction rules:
Extract data from the responses to Web requests
Store results in the test context as name value pairs
Can extract form fields, text, attributes, headers, regular
expressions, and hidden fields.

Web Test

to:

12
13. What Are the Functions of a Load Test?
The primary goal of a load test is to simulate many
users accessing a server at the same time.
Adding Web tests to a load test simulates simultaneous connections to a
server, and making multiple HTTP requests.
Adding unit tests to a load test is equivalent to testing the performance
of non-Web based server components, for example, an application of a
unit test under load is to test data access model components.
13
14. Types of Load Tests
Type of Test Description
Smoke Tests how your application
performs under light loads for short
durations
Stress Determines if the application will
run successfully for a sustained
duration under heavy load
Performance Determines how responsive your
application is
Capacity Planning Determines how your application
performs at various capacities
14
15. Considerations for Choosing Load Profiles
A load pattern defines the number and increase
rate of virtual users active during a load test. The
types of load patterns are:
Constant
Step
Goal-based
15
16. Considerations for Choosing Connection
Models
Connection Model Features Considerations
• Most closely simulates
the behavior of a real
Number of
browser
connections held
• Uses one or two
Connection Per open on the agent
connections per virtual
User computer may be as

high as twice the
• Same connections are re-

requests
• Connections to the Web
server are shared among

Demonstration: How to Access Load Test
Results Using Load Test Analyzer
20
21. How Load Test Analyzer Is Used
Use the Load Test Analyzer to view Load Test
data from a completed test run.
Analyze the test run to locate bottlenecks,
identify errors, and measure improvements.
Load test data contains:
Performance counter samples from the computers under test, plus
any other configured performance counters.
Error and threshold rule violation information.
The test controller saves some performance
counter data for a test run; the amount
saved, and it’s location, is configurable
21
22. What Is the Load Test Repository?
Information gathered from load tests is stored in
the Load Test Results Store.
The Load Test Results Store contains
performance counter data and information
about recorded errors.
Load test run data from previous test runs can
be retrieved using Load Test Analyzer.
22
23. What Is a Test Rig?
A test rig is made up of a test controller and
one or more agents. A test rig:
Provides distributed, automated test execution.
Can simulate hundreds of thousands of users.
Can generate far more load than a single machine.
