Software testing is the process of evaluating and verifying whether a software product or application can complete the expected tasks. There are different types of client side performance testing, such as unit testing, smoke testing, and integration testing. One type is performance testing, which is a non-functional software testing technique used to determine the stability, speed, scalability, and responsiveness of an application under a given workload. There are four types of client side performance testing, namely, capacity test, load testing, capacity test, and stress test.

Performance testing can be performed in two ways, namely client-side and server-side performance testing. Client testing means that experimentation and errors (changes to content) occur at the program level. The enhancer will set a page focused on rules, and the customer's browser will change the current (default) page to the planned page.
Server-side performance testing is the process of testing the performance of a server under various load conditions. This type of testing is important as it can help identify bottlenecks and other issues that may cause servers to slow down or crash under high loads.
Client performance testing means everything, including client operations. This means that when we execute tests on the application based on client operations. Suppose you are considering a web application, and client execution will include server execution and client program delivery, JS/AJAX calls, attachment responses, management information popularity, etc.
Client performance metrics
We can measure different client performance metrics
）Page weight
This measure, also known as total requests', is a collection of asset loads for each site, estimated in kilobytes or megabytes, including the actual HTML of the page. This helps to develop important financial plans on the website, which are not difficult to pass on to engineers and creators. It may not necessarily narrate the entire story of execution in every situation, as execution often heavily depends on how the page stacks these requests.
b) Speed index
The speed index is the score of the visual climax around the top of the page (which is obvious to the client) during long-term operation. It uses video capture to calculate this score. Through web page testing, the time from 0 to an unrestricted score is roughly mapped to milliseconds before the page is fully noticed by the client. The lower the score, the better.
c) Time to the first byte
First Byte Time (TTFB) is an estimate used to measure the responsiveness of web servers or other organizational assets. TTFB estimates the length of the main byte of the page obtained by the client program from the HTTP request made by the client or client.
d) Page loading time
This measurement shows when the pages are completely stacked and begin to become intuitive. Terminate when the asset and its dependent assets complete the stacking process.
e) Interaction time
The number of seconds from the start of routing to the completion of design, the text style of the webpage is obvious, and the page can accept client input. Assuming there are no allocation obstacles for no less than 50ms, balance the page.
f) First important paint
The first important point is a measurement standard provided by a program, which specifies the time required for the most important substance to be fully delivered to the site. It depicts the span until the program initially delivers any text, images (calculation base images), nonwhite materials, or SVG. This combines the up coming web page text style text. This is the main second step for clients to start using page content.
