Response Time Testing
Step 1) Method of calculating metrics gathered by each API response time test tool Step 2) Tools Simulate the load and capture speed which can make a difference in the response time Step 3) Extra items recorded when monitoring user loads Step 4) Computing metrics gathered by each tool increases the response time due to high resource consumption. Step 5) The architecture of the two tools may be different
Types of Response Metrics
Three Important Response Time Values
Response Time Test has two most essential characteristic:
Average response time. Maximum response time.
It shows how long a user needs to wait for the server to the response its request. Following are key Response time testing example values Generally, response time should be fast as possible in the interval of 0.1 – 1 second. However, people can adapt a slower response times, but they will never be happy with a response time greater than 2 seconds. Lesser the response times, better is client satisfaction, lesser costs, higher customer satisfaction.
Response Time Testing Tools
There are many Response Time testing tools are available in the market. Three most prominent Examples of response time testing tools are:
1) JMeter
Apache JMeter is an open source load testing tool. It is designed to measure the performance of websites. This load testing tool can be used in DevOps methodology.
Features:
JMeter allows performing load and performance test for various server types. This load testing tool store its test plans in XML format which allows users to generate the test plan using a text editor. The tool can be used to perform automated and functional testing of the applications.

2) Load runner
Loadrunner from Micro Focus is a widely used Load Testing tool. It is one of the best alternatives to JMeter that offers a user-friendly monitoring and analysis interface with colored charts and graphics.
Features:
Supports continuous testing LoadRunner can effectively work on several enterprise environments It is possible to run multiple protocol script with Loadrunner Integration with various development tools like Visual Studio, Jenkins, Selenium, etc.

Conclusion:
Response time refer to the time take for one system node to respond to the request of another. The Average Response time in performance testing is the average time taken for every round trip request. Peak Response Time helps us to find that what components are potentially problematic. The Error Rate is a mathematical calculation which displays the percentage of problem requests. Three crucial response time values are: 0.1 seconds, 1.0 second and 10 seconds. Three most used response time testing tools are Jmeter, Loadrunner
