izh_test
Kinds of tests
test_script - Sequence of simple test actions

The test command allows assigning value for an environment variable.

<set_environment>
  <name>name of environment variable</name>
  <value>value of environment variable to set to</value>
</set_environment>

name	Name of the variable that should be assigned.
value	Value that should be assigned to the variable.

At the present all the tests except exec_check_directory are executed from a single process. So assigned variable will be assigned for all of the tests executed at the same process.
