运行 1k 用户进行压力测试的最佳实践

Question

Scenario: I wanted to login, get cookies and use that cookies as auth for other api GET request for 10k user. I an using Ultimate thread group with following rows Start Thread Count: 1000 Initial Delay sec: 0 Startup Time: 1000 Hold Load for: 300 Shutdown:0

Does it make any difference on sever If I used single user login or I need to need to use 1k login details? , In that case as cookies are stored under browser local storage, so I am using web driver sampler to get that, so for 1k how will it be possible.

Similarly said by client to do for 10K 20k and so on.

As I am new, figuring out what is best possible way to get this done, am I on correct direction, kindly mentor me out.

Thanks

1. Does it make any difference on sever If I used single user login or I need to need to use 1k login details? we don't know, it depends on the particular server implementation. From the black-box testing perspective I would go for "realistic" approach and use different credentials/cookies for different users
2. In that case as cookies are stored under browser local storage, so I am using web driver sampler to get that If after login you get the Cookie which can be used for authentication/authorization in an API request there is no need to use Selenium, with JMeter you can get the cookie value from the Set-Cookie response header either manually using suitable Post-Processor or automatically using HTTP Cookie Manager
