Test Plan
It is used to describe a test scenario, including all relevant functions for this performance test. That is to say, all the content of this test is based on a plan.
The "Function Test Mode" checkbox, if selected, causes Jmeter to log data from each sample returned from the server.
Thread group Threads (Users)
NOTE: Stepping Thread Group can be used to simulate step pressurization!
thread group
This is the thread we usually add to run. Generally speaking, a thread group can be regarded as a virtual user group, and each thread in the thread group can be understood as a virtual user.
Ramp-Up Period: The unit is seconds, the default time is 1 second. It specifies the time it takes to start all threads. If you need Jmeter to start all threads immediately, set this to 0
Number of loops: Indicates how many times each thread executes the request.

Sampler _
A sampler is the smallest unit that sends a request to the server, records the response information, and records the response time in the test. JMeter natively supports a variety of different samplers.
Such as HTTP Request Sampler, FTP Request Sampler, TCP Request Sampler, JDBC Request Sampler, etc. Higher versions of jmeter support richer Samplers
