Tread Group

3hread 6roups is a collection of 3hreads. #ach thread represents one user using

the application under test. Basically each 3hread simulates one real user request to

the server.

3he controls for a thread group allow you to "et the number of threads for each

group.

-or e+ample, if you set the number of threads as ;::? JMeter will create and

simulate ;:: user requests to the server under test.

SamplersJMeter supports testing H33@, -3@ , J$B/ and many other protocols.

3hread 6roups simulate user request to the server 3he user request could be-3@ Aequest, H33@ Aequest, J$B/ Aequest...#tc.

*et imagine you want to performance test an -3@ server. !ou can use -3@ request

sampler in JMeter to do this task. 3his controller lets you send an -3@ downloadfile or upload file request to an -3@ server.

-or e+ample, if you want to download a file 3est.t+t from a -3@ server under

test, you need to configure some parameters in JMeter as figure below

TT. re/uest0

3his sampler lets you send an H33@)H33@" request to a web server. /onsider the

e+ample below. JMeter send a H33@ request to 6oogle website and retrieve H3M* files

or image from this website.

3his sampler lets you e+ecute $atabase @erformance 3esting. 't sends a J$B/ Aequest

0an "C* query2 to a database.

-or e+ample, a database server has a field testDresult stored in a table name testDtbl.

!ou want to query this data from the database server? you can configure JMeter to send

a "C* query to this server to retrieve data.

S- Sampler0

3his sampler allows you to write a sampler using a B"- scripting language.

Here is an e+ample of B"- "ampler in Jmeter
