Hello Celalettin,
| How can I run a test that, a group will already be login and try to add-to-chart, while another vuser groups doing different tasks like login and browse pages etc.? |
You need to record tasks like this: Login, AddToCart, Browse, Logout.
Then you will create two Complex Tasks:
Complex Task 1 will contain Login, AddToCart, Logout;
Complex Task 2 will contain Login, Browse, Logout.
You will assign the two complex tasks to two different Virtual User groups, and all of the VUs will run in parallel.
BTW, we have recently posted an article related to Complex Tasks usage - it may be helpful, take a look:
