What is JMeter?

Apache JMeter is an open-source tool used for load testing, performance testing, and functional testing of web applications. It was initially developed for testing web applications but has since evolved to support testing protocols and technologies such as FTP, SMTP, JDBC, and more.

It is a Java-based tool that can be used on any platform that supports Java. It supports multiple threads, allowing users to simulate multiple users simultaneously. In addition, users can configure the number of threads and the ramp-up time to gradually increase the application load.

It’s user-friendly GUI allows users to create and configure test plans easily. In addition, it supports various types of samplers, controllers, listeners, and assertions that would enable users to simulate real-world scenarios and measure the application’s performance under different load conditions.

It also provides extensive reporting and analysis capabilities, allowing users to generate various reports, such as summary reports, graphs, and charts. It also supports distributed testing, allowing users to distribute the load across multiple machines to simulate many users.

Overall, it is a flexible and powerful tool well-suited for load testing of web applications and other services. In addition, it’s open-source nature and wide community support make it a popular choice today.

}
GET http://example.com/
Response Assertion:
– Text Response: ${__P(ExpectedText)}

In the above example (Bash), JMeter sends an HTTP GET request to the URL “http://example.com/”. The “Response Assertion” component is then used to check if the response from the server contains a specific text string, specified by the “__P(ExpectedText)” function.

What is LoadRunner?

Understand “JMeter vs LoadRunner” — LoadRunner is a proprietary tool developed by Micro Focus that is used for load testing, stress testing, and performance testing of web and mobile applications. It supports many technologies and protocols like HTTP, HTTPS, SOAP, and more. It can simulate thousands of users and measure the performance of the application under various load conditions.

It comprises several components, including the Virtual User Generator (VUGen), Controller, and Analysis. VUGen is used to create scripts that simulate user actions on the application. The Controller is used to manage and execute load tests, while Analysis is used to analyze the results of the load tests.

Action()
{
lr_start_transaction(“Transaction Name”);

web_url(“Web URL”,
“URL=http://example.com/”,
“Resource=0”,
“RecContentType=text/html”,
“Referer=”,
“Snapshot=t1.inf”,
“Mode=HTML”,
LAST);

lr_end_transaction(“Transaction Name”, LR_AUTO);

return 0;
}LoadRunner sends an HTTP GET request

In this example, LoadRunner sends an HTTP GET request to the URL “http://example.com/”. The “lr_start_transaction” and “lr_end_transaction” functions measure the time taken to complete the request and calculate the response time. The “web_url” function is used to simulate a user clicking a link in a web page, and the “LAST” parameter indicates that this is the last parameter for this function call.
