What is Microsoft Application Test Center?
Application Center Test is designed to stress test Web servers and
analyzes performance and scalability problems with Web applications, including
Active Server Pages (ASP) and the components they use.
Application Center Test simulates a large group of users by opening multiple
connections to the server and rapidly sending HTTP requests.
Application Center Test supports several different authentication schemes and
the SSL protocol, making it ideal for testing personalized and secure sites.
Although long-duration and high-load stress testing is Application Center Test's
main purpose, the programmable dynamic tests will also be useful for functional
testing.
Application Center Test is compatible with all Web servers and Web applications
that adhere to the HTTP protocol.
ATC Functional testing Documents
ATC functional test is used to determine the proper functioning of the
pages. By using ATC functional test you can specify the dependency of one page
to another. It has got two scripting language.
-
VB Script
-
J Script
Through these
scripting languages you can specify your own logic for page browsing. Basically
Application test center provide different way to call web page by specifying its
URL.
Through this you can assure that every page is working fine. Suppose in case if
your page is getting some error while rendering on the browser than it gives you
all the details of error. Application test center also generate report for
successful test.
How you do that?
First of all you have to create a new test project using Microsoft
Application Test center and than you can specify your test case.
For testing a particular URL you can create test case in Microsoft Application
Test Center. There are two options available.
-
Create an empty
test.
-
Record a new Test.
Creating an empty test
Create empty test option creates a test file using default content and
setting. After selecting empty test you can choose language to create test
logic. There are two options for programming language.
-
VB Script
-
J Script
after selecting script
language you can give any name to the test. When you create an empty test case
it automatically generate one liner code.
Test.SendRequest ("http://localhost")
For writing your own test case you can change the code and you can mention your
own URL for testing.
You can now set properties for Test by property window of Test. You can pop up
property window of test case by either right clicking on that test and selecting
properties Or by directly clicking on property tool of tool bar.
Through this you can specify the number of users, number of simultaneous
browser, Performance counter, number of times and test time duration etc.
After creating test and fixing all properties you can run test by using run tool
in the tool bar.
It generate report for your test by default it store the report in the
installation directory's ACTTrace.txt you can modify that path by project
properties.
For each test run it generate the test result and stores in Result section of
the project.

The Test Result give you detail report of test.
Record a new test
Record a new test basically create new test by recording a web browsing
session.
New test is slightly different from empty test. It automatically sends request
is slightly different for this you have to click on start recording to create
new test. It creates different request to the server and creates automated
script for that.
You can press stop recording to limit the number of test request. Rest of the
test procedure is same as empty test but in record test you can specify your own
logic by modifying the auto-generated test by application test center.
Conclusions
Microsoft application test center is a power tool for performing functional as
well as performance testing of your web site. It makes your job easy by auto
generating test. It has also got lot of functionality, which provides an easy
way to perform functional testing of your site.
It comes with Microsoft visual studio .NET.
