**loop** test items
|
|
============================================================
|
|
|
|
This element is of the following form:
|
|
|
|
.. code-block:: yaml
|
|
:caption: ``loop`` test item usage example
|
|
|
|
- loop:
|
|
name: Cycle Temperature
|
|
iterator: 10
|
|
steps:
|
|
- unittest:
|
|
test_file: test_prod_rio6_8093.py
|
|
- py_func:
|
|
name: function test item
|
|
file: scriptTestFile.py
|
|
func_name: funcToBeExecuted
|
|
param:
|
|
- $(loop_param)
|
|
exit_condition:
|
|
file: script_name.py
|
|
func_name: methodName
|
|
|
|
The loop element executes repeatedly the ``steps`` sequence of items.
|
|
|
|
The configuration of the iteration process is done according to the iterator
|
|
cycle sub-item. As described later in this chapter the iterator is
|
|
configurable per cycle and allows to call a python function at each
|
|
cycle loop.
|
|
|
|
Attributes
|
|
----------------
|
|
|
|
Below are described loop test item specific attributes.
|
|
|
|
* ``Iterator``: giving the number of loop iteration (see dedicated chapter below).
|
|
* ``steps``: describes the sequence executed at each cycle; it is
|
|
a list of any of the testium test items.
|
|
* ``exit_condition``: allows to exit the loop. If True is returned loop continues
|
|
otherwise it breaks. exit_condition attributes are:
|
|
|
|
* ``time``: the loop stops after the time (in minutes) is elapsed (optional)
|
|
* ``value``: the loop stops when the content of the value attribute is
|
|
True (optional)
|
|
* ``file``: the loop the script file name that contains a function to be
|
|
executed on each loop. Only python script format is supported (optional
|
|
if another exit_condition attribute is defined)
|
|
* ``func_name``: the function to execute on each loop when the file attribute
|
|
is defined. The function referenced by the ``func_name`` attribute must
|
|
have two parameters: the current loop iterator value and the report,
|
|
even if they are not used. This attribute is mandatory if the file
|
|
attribute is defined.
|
|
* ``eval``: optional parameter allowing post treatment of the function result.
|
|
It is a python evaluable string in which the ``$(result)`` keywork
|
|
is replaced by the actual function call result (see exemple below).
|
|
|
|

:caption: ``loop`` exit condition
|
|
|
|
- loop:
|
|
...
|
|
exit_condition:
|
|
file: script_name.py
|
|
func_name: methodName
|
|
eval: $(result) < 2
|
|
|
|
**Iterator**
|
|
|
|
The iterator attribute can be of the following types:
|
|
|
|
* An integer giving the cycle loop number,
|
|
* A list. The number of elements of the list gives the loop number, and
|
|
the list member are the consecutive loop parameters,
|
|
* Undefined. Then cycle loops until the exit condition is reached.
|
|
|
|
**Loop variables**
|
|
|
|
The following loop variables are automatically defined:
|
|
|
|
* ``$(loop_param)``: parameter of the loop. It contains the iterator value.
|
|
* ``$(loop_index)``: index of the loop, starting with 0 and incremented at each cycle.
|
|
* ``$(loop_index_inverse)``: inverse of index of the loop, starting from cycle length
|
|
-1 and decremented at each cycle.
|
|
* ``$(loop_count)``: loop total iteration number. If the number of loops is undefined
|
|
its value is the python ``inf``.
|
|
|
|
When these variables are found in a parameter, an attribute, etc, a
|
|
loop is searched recursively in the test hierarchy. And the variable value
|
|
is replaced by the corresponding loop value.
|
|
|
|
If more than one loop exists in the test item hierarchy, the lowest level
|
|
loop iterator is used.
