JMeter about setting thread group and time

1. Thread group - Scheduler - The elapsed time （ Upper right corner ）

A： Number of threads ： Set the execution times of the thread group . for example （1 A thread group （ It contains 9 A request ）, Set the number of threads to 10, execute 10 Threads （ In total 90 A request ）; Multiple thread groups , Then each thread group executes once according to a single thread group ） ;

B： The duration of the ： How long does the test plan last （ Can contain multiple thread groups ）; Set to 100s That is to say, the running time of the whole test plan is 100s, Execute these requests within this time ;

C： The elapsed time , The running time of the current test ; Next to that is the number of threads currently running / Total number of running threads

2. Thread group -ramp-up period- The elapsed time （ Upper right corner ）

A： Number of threads ： Set the execution times of the thread group . for example （1 A thread group （ It contains 9 A request ）, Set the number of threads to 10, execute 10 Threads （ In total 90 A request ）; Multiple thread groups , Then each thread group executes once according to a single thread group ） ;

B：Ramp-Up Time （ second ）： The time interval between the start and start of a thread , Unit second . That is, how long all threads start . For example, threads 60 individual ,Ramp-Up Period Set to 20s, Then start every second 60/20=3 Threads , Do not fill in the default setting is 0, That is, all threads are started immediately after the scene is started .

C： The elapsed time , The running time of the current test ; Next to that is the number of threads currently running / Total number of running threads

3. The elapsed time - Scheduler （ The duration of the ） The relationship between

The two times are basically the same
