performance testing questions code example

Example 1: performance testing test cases

1. Check if the page load time is
within the acceptable range.
2. Check the page load on slow connections.
3. Check the response time for any action
under a light, normal, moderate, and heavy load conditions.
4. Check the performance of 
database stored procedures and triggers.
5. Check the database query execution time.
6. Check for load testing of the application.
7. Check for the Stress testing of the application.
8. Check CPU and memory usage under peak load conditions.

Example 2: what is performance testing

PERFORMANCE TESTING

What is Load testing?
Load testing is the process that simulates
actual user load on any application or website.
It checks how the application behaves during normal
and high loads. This type of testing is applied
when a development project nears to its completion.
Load testing is performed to determine how many
users the system can handle.

What is Stress testing?
Stress testing is testing that checks the upper
limits of your system by testing it under extreme loads. 
Stress testing is a type of testing that determines
the stability and robustness of the system. 
It is a non-functional testing technique.
This technique uses auto-generated simulation
model that checks all the hypothetical scenarios.

When do you use Performance Testing?
Performance testing is done to check the
performance of website servers, database, and network.
If you are adopting waterfall methodology,
then it is important for you to check each time
release of a new version. However,
if you are using the agile software development approach,
then you need to test application continuously.
