Basic introduction of JMeter

Beginner JMeter, Below is my commonly used function, summarizes.

1. Thread Group Thread

Thread groups, that is: virtual user groups

Name: Feel free to get up, I like it better.

Number of threads: Sets the number of virtual users.

Ramp-up Period (in seconds): Set the time, that is, to create the number of virtual users you set during this time period.

Number of Cycles: 1 threads run how many times the test. (If you tick "forever", it will continue to circulate)

Scheduler (Scheduler): Configures the start time.

Duration: Set How long this test runs.

Start delay: After a delay of x seconds, start the test.

Start time-end time: Set the test to run within a fixed time period.

2. Synchronizing Timer (concurrency)

(because JMeter is executed in a tree-like structure, it is usually placed and issued before the request)

Number of simulated users to Group by: simulates multiple threads (users) making requests to the server at the same time . (also called Rendezvous Point, synchronization point)

(If 0: it is equivalent to setting all threads concurrently.) ）

Timeout in milliseconds: Wait time (milliseconds), that is, if the number of threads at this time is less than the number of concurrent, wait for x milliseconds (regardless of whether the number of threads at this point reaches the concurrency value), release the remaining threads.

(if 0 and the number of threads cannot reach the concurrency value, the timer will wait indefinitely unless manually terminated)

Note: Set the number of concurrent numbers that should not be greater than the number of users included in this thread

3. Http Request (requests)

Server name or IP: server address

Port number:

Protocol: HTTP

Method: GET (mostly the Web page you are measuring to take what method you use.) I do not know F12 see a ha)

Path: The part after the domain name in the address

Parameters parameter: Key-value parameter value

Body Data:① directly fill in the data; ② or read from text, format: ${} fill in the variable name → The variable is the data you read from the text, give it a new definition of a name
