Introduction It is a process of validating application terms of responsiveness and
stability under a particular workload.
It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage.
There are three objectives (three S) of Performance testing to observe and evaluate;
Speed, Scalability and Stability
PTLC
Load Testing 1. Load Testing
Load Testing help us to study the behavior of the application under various loads. The main parameter to focus is response time. This study reveals how the application handles concurrent users effectively.
Main parameter to focus: Response Time
Stress Testing 2. Stress Testing
Stress Testing help us to observe the stability of the application. The main intention is to identify the breaking point of the server. The main parameter to focus is throughput (how much data is being transferred between client and server)
Main parameter to focus: Response Time and Throughput
Endurance Testing 3. Endurance Testing
Endurance testing reveals about memory utilization when you load your test for prolong executions. Say if you execute your test 1 hour to perform load testing. But in endurance testing, you execute your test at least for 8 hours with significant load.
Main parameter to focus: Memory
Spike Testing 4. Spike Testing
Spike Testing is performed by sudden increase/decrease in load and observing the behavior of the application. This help us to determine whether the application can handle or not under significant changes in the load.
Main parameter to focus: Response Time
Volume Testing 5. Volume Testing
Volume Testing is performance to identify whether the server can handle more number of high complex queries under significant load. The main intention is to observe how the database acts under various circumstances.
Main parameter to focus: Response Time of Queries
Availability Testing 6. Availability Testing
This test ensures whether the application is available 24x7x365 days. If you would’ve noticed any website hosting providers, they advertise as 99.9 per cent up time. Availability testing helps us to determine whether the application is up and running fine without any issues.
Main parameter to focus: Response Time
Scalability Testing 7. Scalability Testing
Say, your website has 1000 visitors per month with 10% increase in unique visitors. By forecasting the number of visitors by expected business growth and performing the load test is called scalability testing.
Main parameter to focus: Response Time and Maximum Transactions Per Second
Response Time After a request is sent to an application, "response time" measures how long it
takes for a response to return back from the application.
This is also sometimes referred to as "round-trip" time
Slow response time equals an unhappy user experience, and may also result in the loss of revenue.
Throughput Throughput” is the amount of transactions produced over time during a test.
It’s also expressed as the amount of capacity that a website or application can handle.
before starting a performance test it is common to have a throughput goal that the application needs to be able to handle a specific number of request per hr.
