The scenario in my project is like as following
step 1: USER_A login his homepage , send a message[MSG_TYPE1] to USER_B .
step 2: USER_B login his homepage and he will see the message form USER_A
step 3: USER_A continue sending a message[MSG_TYPE2] to USER_B .
step 4: USER_B check the message again
In acceptance case , is there a good way to implement the scenario ?
Logout USER_A then login USER_B is a quite unelegant way .
