JMeter CSV import functionality

Hi dude

Here how to use CSV import functionality in the JMeter.


In the JMeter , as usual normal recording the page and add the thread group under Test Plan

Then Add the CSV import functionality in the  below the requested URL to import the data from the CSV file.

Add the CSV data set config via

Add -> Confiq Element -> Select CSV data confiq

See the Picture

In the CSV file if u add 3 colums(username, Password, Country) . In the CSV file no need to add header just enter the data .in the variable declare enter the value (username, Password, Country).

then add the variable in the HTTP request value , replace the recorded value with the variable we assigned in the CSV data config.

See the picture for your reference

Just assign the value by enter ${username} like that we place in the value field. If you want to see the result exactly means save the response fie or see the view results in Table listener.

Bottleneck Problem

BottleNeck Definition :

A bottleneck is a phenomenon where the performance or capacity of an entire system is limited by a single or limited number of components or resources. The term bottleneck is taken from the 'assets are water' metaphor. As water is poured out of a bottle, the rate of outflow is limited by the width of the conduit of exit—that is, bottleneck. By increasing the width of the bottleneck one can increase the rate at which the water flows out of the neck at different frequencies. Such limiting components of a system are sometimes referred to as bottleneck points.

A bottleneck in project management is one process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain.

Related concepts in project management are:

• Critical path method
• Theory of Constraints

And an example is the lack of smelter and refinery supply which cause bottlenecks upstream.

Another example is in a Surface Mount Technology (SMT) Board Assembly Line with several equipments aligned, usually the common sense is driven to set up and shift the bottleneck element towards the end of the process, inducing the better and faster machines to always keep the PCB supply flowing up, never allowing the slower ones to fully stop, a fact that would be heeded as a deleterious and significant overall drawback on the process.

Bottleneck occurs in decision making process.

Four bottlenecks that may occur:

1. Global versus Local
2. Center versus Business Unit
3. Function versus Function
4. Inside versus Outside Partners

Using JMeter we can able to identify the bottleneck of the problem by combining the tool using Visual VM

J-Meter Assertions

Assertion allows you to assert facts.

What assertion do..

Assertion is just check the response whether the required data is there or not

It is simply verifying the content in the response .

Some Assertions are mentioned here

Response Assertion:

Response assertion is simply check the response from the server. For Example the response from the server is "Testing" if you place the assertion in the corresponding  request and add the assertion under this

Also want to know the result

Add the Assertion Listener . It show the result. When the Assertion is correct it not give any result in the Assertion result page it just give the HTML name (What u given as name)

Result of Response Assertion

Duration Assertion

Simply tell the duration time here(Response time from the server)

HTML Assertion

This assertion check the html errors in the page.This concept can be checked by Jtidy tool merged with JMeter
