Scriptless Testing
|
|
No
programming knowledge is
necessary to create,
comprehend, edit or execute
a performance test. Tests
are displayed as
hierarchical list of the
Web pages that will be
visited during execution.
While test complexity is
masked by default, advanced
testers have access to all
transactional information
such as underlying page
elements and server
responses.

Find and
diagnose the cause of
performance problems
|
|
Rational
Performance Tester goes
beyond problem
identification to problem
diagnosis. Using Root Cause
Analysis features, you can
identify both the source
code and physical
application tier that is
causing the bottleneck.
With the generated UML
sequence diagrams you can
trace all activity that
occurred just prior to the
bottleneck to truly enable
you to address the root
cause of your performance
problem.
|
|
Integrated Resource
Monitorng
|
|
Testers
must be vigilant to detect
performance and reliability
problems that can be traced
to hardware issues. IBM
Rational Performance Tester
can collect and display
multiple resource
statistics from any tier of
the system under test,
thereby exposing hardware
related bottlenecks
responsible for poor
performance.
|
|
Real-time reporting for
immediate performance
problem identification
|
|
Rational
Performance Tester
generates performance and
throughput reports in real
time, enabling you to
detect performance problems
at any time during a test
run. These reports provide
multiple filtering and
configuration options that
can be set before, during,
and after a test run. Users
can also review performance
trends from one build to
another. Additional reports
are available at the
conclusion of the test run
to perform deeper analysis
on items such as response
time percentile
distributions.
|
|
Run
large multi-user tests with
limited hardware
|
|
Rational
Performance Tester can be
configured to generate user
loads from remote machines
using an easily deployed
execution agent. This
execution agent has been
optimized for low memory
and processor usage. As a
result, teams with limited
hardware resources are able
to generate very high
volume user loads for their
tests.
|
|
Automatic identification
of, and correlation of
dynamic server
responses
|
|
Server
responses may vary
according to what data the
user enters. Often, these
responses have a bearing on
future information that
will pass between client
and server. IBM Rational
Performance Tester can to
detect these dynamic server
responses and automatically
make them accessible for
re-use in tests involving
subsequent server requests.
This capability ensures
that your tests’ virtual
users will accurately
emulate the system load of
a real world user
population.
|
|
Automated test data
variation
|
|
For
accurate load emulation,
often individual users must
submit unique data to the
server. IBM Rational
Performance Tester provides
an automated "data pooling"
capability that varies the
test data set used by each
emulated user. A
spreadsheet interface is
provided to enter this
unique data, or
pre-existing data can be
imported from any text
based external source.
|
|
Accurate
user profile workloads
|
|
To
ensure that your
performance testing
accurately mirrors your
user population, IBM
Rational Performance Tester
provides a flexible
graphical test scheduler
where load is specified by
proportional user groups.
Performance Tester also
provides synchronization
points to create real world
scenarios and allows for
scheduling of those points
for improved control of
workflows and simulated
conditions (stress points)
on the Web server. This
enables you to create a
workload on your server
that is truly
representative of your user
mix.
|
|
Rendered
HTML view of Web pages
visited during test
recording
|
|
Users
can review Web pages
accessed during test
recording using a
browser-like window
integrated with the test
editor. This window shows
you what the user would see
when visiting a selected
page, helping you make more
informed decisions about
how to modify your tests
prior to execution.
|
|
Java
code insertion for flexible
test customization
|
|
Advanced testers have
the option of inserting
custom Java code into their
performance tests to
perform activities such as
advanced data analysis and
request parsing.
|
|
Linux-based user interface
and test execution
agents
|
|
The
Performance Tester recorder
and editor can be used on
both the Windows and Linux
platforms. Test execution,
which can occur both
locally and on remote
machines, includes support
for Windows and Linux.
Remote test execution
allows teams to take
advantage of additional
hardware resources,
enabling very large scale
performance tests.

Performance Tester allows
users to test applications
that are secured with
Entrust TruePass
Technology.
