Synchronize 2 scripts

In order for 2 tests on two different devices to synchronize or communicate with each other, they must :

Run the 2 GDSL scripts simultaneously
In each scenario, create waiting of element steps or trigger events.

Wait for an action from the second script

To wait for an action from the other script, you need to :

Find an element in the interface that the actions of the second script will change (appear or disappear).
Watch for the arrival or disappearance of this element with a while loop that will run a maximum of 20 times.

To avoid these 20 iterations running too fast, and leaving no time for the other script to make the element appear/disappear, a pause time must be defined inside the loop.

Notice that in some applications, a page refresh may be necessary to make the expected element appear/disappear.

Example of waiting for an element, with page refresh :

while,notExists,text,textWhichShouldAppear
do     
    clickById,refresh 
    pause,10000 
done
