5 Things To Do When Load Testing

Load testing involves the design and execution of tests to examine the
performance of a system. The objectives of load testing are to measure a
system’s behavior patterns under certain conditions and determine its
capabilities. Running different tests on your website or application will
produce many outcomes depending on the configuration of your load tests. When
conducting load tests it is important to do these five things to ensure your
website or application undergoes quality tests.

Clear cookies and browser cache before recording traffic

While conducting load tests, it is important to clean your cookies and cache
such that when you record a user scenario, the browser cannot use cached data
to load client requests. Clearing cookies and cache ensures that the browser
sends and receives data and responses directly from the server.

Verify scenarios

When planning to conduct a load test, first ensure that the scenario you
intend to test has already been successfully executed for one virtual user.
This will allow you to identify any problematic attributes of the scenario and
help you fix those problems before-hand such that you may not relate them to
the number of virtual users or the testing conditions.

Record the scenarios right from the start of the browser

This is because recording scenarios after opening a few web pages will cause
the scenario’s playback to fail. This mostly happens due to failure of the
recorded traffic to repeat the authentication process which leads to the
tested web server ignoring further requests to do so.

Parameterize your scenarios

Creating variable values when conducting load tests allows you to achieve
realistic load results on the server. For instance, when you replace recorded
parameters with other values in the server, it allows you to receive
user-specific data in the request s from virtual users. Analyze the
possibilities of parameterizing through careful evaluation of the responses
and requests of the data transferred to and from the server. Parameterizing
scenarios creates an opportunity to include a wide range of behaviors to the
scenario to have it run as though its users are a unique group of individuals.

Don’t conduct load tests in real environments.

Load testing in a real environment where network traffic is high can alter the
results of the load test. This is due to the large data transfer in the
server. Always opt to use an environment that has the same behavior patterns
as a real environment but has no other traffic usage other than your scenario.
