A load testing solution for web sites

In short, it is a simulation of multiple users visiting a web site
at the same time and working with it concurrently.

Such general definition makes a blanket term for
several different types of testing.

Volume Endurance Regression

Performance testing

We gradually increase the load by adding more and more virtual
users to the test and check the performance parameters of the
system at any test phase.

The main things we monitor are:

• Web site response time;
• Number of processed requests per second;
• Error rate.


Capacity testing

This type of test replies to the most common question in load
testing: how many concurrent users the web site can handle while
maintaining good response time and error rate.

Again, we add virtual users gradually, but in this case we know the
performance criteria in advance and just need to check that they are
observed.


A typical problem revealed by a performance or
capacity test is a bottleneck. Even though it is
mostly a technical term, it can be thought of as a
thin section within the data workflow.

Your web application can consist of several modules used to
process requests. If one of them has a technical limitation, it
limits the performance of the whole system.


Stress testing

Every system has a capacity limit. When the load goes beyond it, the
web site starts responding very slowly and even produce errors.

The purposes of stress testing are:

• Find the capacity limit;
• Check that when it is reached, the web site handles the
stress correctly: produces graceful overload notifications
and does not crash;
• When the load is reduced back to regular level, the web site
returns to normal operation retaining the performance
characteristics.


Volume testing

If your application can upload files, upload the largest ones. If it does
the search, try generating long results.

Try to maximize the amount of processed data and the complexity of
each transaction. This will be the volume testing.


Endurance testing

This type of testing (also called “soak testing”) is used to check
that the system can stand the load for a long time or a large
number of transactions.

It usually reveals various types of resource allocation problems. If a
small memory leak is present, it is not evident on a quick test, but
will influence the performance after a long time.

For endurance testing it is recommended to use changing periodic
load to provoke resource reallocation.


Regression testing

Make the load testing a part of your regular development process
by creating regression load tests and applying them to every new
version of your application.


You can design tests as easy as using a browser. Just navigate
through the web site to record a user session. WAPT will
replay it with thousands virtual users during the test.

• No scripting is necessary.
• No programming background is required.
• The efficiency of your work is our priority.

headers, page You can and other options.


The test may include different
profiles to emulate different
types of users.

The load is flexibly specified: you can select how
many users of each type should participate.


And you can make the number of virtual users change. This way you
can emulate different types of load.
It can be

Or periodic.


Automatic cookie and
session variables handling
will make each user session
correct and realistically
emulated.


With couple clicks you can create data-driven tests by specifying
different names, passwords and input data for different users.


Any dynamic values in the test can be parameterized with
help of special WAPT functions.
You can extract values from server
responses and reuse them in
subsequent requests.


You can test secure
HTTPs pages and web
sites requiring all types
of authentication and
client certificates.


On the test completion you get the report containing comprehensive
statistical information, including response times, throughput parameters,
bandwidth usage, errors appeared at each test phase and much more.


You are not limited to analyzing rows of numbers with statistical data.
WAPT can represent it in form of dynamic resizable charts.

Using them, you can track down the correlation of any performance
parameters with the created load at any test moment.


When your web application starts producing errors on test execution,
you may need to have the detailed information on each user session
and each request in order to track down the problem.

In WAPT this
information can be
fully logged during
the test and
represented in a
convenient
structured form
after the test
completion. You
can easily navigate
between users,
sessions and
reported errors.


Many of our customers use load testing on a regular basis as a part of
their development process. They often need to perform the testing
from different locations and create significant test load emulating
thousands users.

To address the need for a more powerful, flexible and precise testing
tool we offer the professional version of our product.

It can use several systems for load generation, overcoming any limits
for the maximum emulated test load.
But this is not the only benefit…

WAPT Pro consists of the workplace component and multiple load
agents that can be installed anywhere and managed remotely.

Such location independent distributed configuration makes WAPT Pro
an ideal cloud-ready solution.


These days a typical web site may include multiple components, such
as load balancers, web servers, application servers, databases, etc.

When applying a load test to such a complex system, the classical
black-box approach will hardly work. To track down the performance
problems, isolate bottlenecks and optimize the hardware configuration,
it is often required to monitor the behavior of each system component
under load.

WAPT Pro uses WMI and SNMP interfaces to collect the
exhaustive performance information directly from
each server and database.


Web sites featuring rich AJAX content often require advanced
parameterization techniques. WAPT Pro guarantees that any such web
site can be fully tested by providing a possibility to prepare dynamic
request parameters and post-process server responses with help of
custom JavaScript code.

While the Pro version follows the
same intuitive GUI approach to
the test creation and execution,
it adds the scripting possibility
for advanced users as an option
that can be selectively applied.


As more and more new technologies are becoming standards for web
development, we are working hard to address the requirements for
load testing of RIA (Rich Internet Application) web sites.

For each specific technology we
create a special module that
extends the capabilities of our
products.
The benefits provided by these
modules include:

• Support for binary data
formats;
• Visual representation of
embedded structures;
• Automatic parameterization of
protocol-specific data.


Right now we have the following modules available:

Module for ASP.NET testing

Module for Adobe® Flash® testing

Module for JSON format

More coming soon…


We do not simply sell our software to you. We see the
communication with each of our customers as a
process that starts before we make the sale and may
develop to any type of collaboration in the future.

We provide free technical support on the product
functionality and general load testing practices. It is
fast and efficient, because we believe that this is what
you actually pay for when you purchase our products.

In addition we provide consulting services, so if you
wish, you can fully outsource the load testing tasks
to us.


Product documentation: from Quick Start Guide on the
main WAPT features to the complete online help.

Technical video demo of the product usage.

The “On Load Testing” blog: industry news, best practices,
product announcements and more.

Online forum where WAPT users share their
experience.


Thousands businesses from all around the
world have already chosen our products.

Our customers range:
• from financial to government institutions;
• from IT service providers to energy sector;
• from small private companies to
international corporations.

Our mission is to professionally
analyze the load testing
requirements of each of our clients
