Abstract: In one aspect, there is an apparatus. The apparatus may include at least one processor, and at least one memory including computer program code. The at least one processor, the at least one memory, and the computer program code may be configured to cause the apparatus to perform operations including detecting, at a first synchronization application, an event representative of an action on a user element of a test web page. The operations may further include sending, by the first synchronization application, the detected event and an indication of the test web page to enable rendering of the test web page at a second device including a second synchronization application.
