When all the tasks of the same family share the same variable value,
the value could be defined at the family level.
This is termed variable inheritance
In the examples below the variable could have been defined at the
level of the suite, achieving the same results.
Variables are inherited from the parent node.
If a variable is redefined lower in the tree, it is said to be overridden.
In this case, the new definition is the one being used.
It is possible to override the generated variables.
This is not recommended and you should understand all the consequences
if you decide to do so.

Quiz
Let us have a quiz. Consider the following suite:
| Code Block |
|---|
suite test
edit SLEEP 100
family f1
edit SLEEP 80
task t1
task t2
edit SLEEP 9
family g1
edit SLEEP 89
task x1
edit SLEEP 10
task x2
endfamily
endfamily
family f2
task t1
task t2
edit SLEEP 77
family g2
task x1
edit SLEEP 12
task x2
endfamily
endfamily
endsuite |
Here is the value for SLEEP for the above suite. Make sure you understand this.
/test/f1/t1 80 /test/f1/t2 9 /test/f1/g1/x1 10 /test/f1/g1/x2 89 /test/f2/t1 100 /test/f2/t2 77 /test/f2/g2/x1 12 /test/f2/g2/x2 100
