Re: ATEasy Python Driver

Hi,

My team is waiting for new ATEasy Python Driver to integrate it in the project.

The plan is to use driver instead using STDIO Process.

Re: ATEasy Python Driver

Hi,

Attached is a pre-release of Python driver/example.

This is a preliminary and we will add more features in the future (v11).

You will need to install Python 3.8.2 from https://www.python.org/downloads/.

If you need or have request for additional features, please open a support incident and paste your request there.

Ronnie

Re: ATEasy Python Driver

Hi,
Thank you very much for this amazing driver.
Verified the examples and look very good.
One point, that I can to understand is how we can catch the exception:
! Raise Python Exception and catch in ATEasy
if PYTHON Run("raise Exception('Exception')")=-1
    TestStatus=PASS
else
    TestStatus=FAIL
endif
How it's work? I add some exception in example file, but it's not visible in ATEasy.

Re: ATEasy Python Driver

Hi Roman,

PYTHON Run("raise Exception('Exception')") doesn't run the example script. It just interpreters one line in Python. For example, the below would raise a differently named exception in Python:
raise Exception('TheNameOfMyRaisedException')

This returns -1 if an exception was raised (and it is):
PYTHON Run("raise Exception('Exception')")=-1

Hope that helps.

Tero

Re: ATEasy Python Driver

Hello Tero And Ron,
Thank you very much for this driver !

I have 2 question regarding the usage:
1. where do the print statements go ? where can i see them ?
2. how can i use the driver when creating an object in OO python  ?
for example,if i run 10 tests and all of them use  a PSU object for example how can i pass the object between the tests ?

Regards,
Idan

Re: ATEasy Python Driver

Hi Idan,

I am working on examples for your question 1-3. We'll post the updated driver example with respect to your needs as soon as possible.

Re: ATEasy Python Driver

Hi Idan,

Yes, the driver was updated with examples to match your questions. As soon as it's merged, we'll post it for you.  
  1) By default, the standard output stream in Windows. From Python, you can use file-like objects to redirect the stream as you wish, or like it was done in the new example, overriding the sys.stdout.write method.
  2) You can reference the corresponding Python objects and save their addresses to an ATEasy variable.
  3) You can call your class constructor, Python object, in a similar manner to a def

Tero

Re: ATEasy Python Driver

Hello Tero and Ron.

Thank you very much for this driver !
i have 2 question regarding the class usage.

1. hPyArgs=PYTHON Set Args Tuple({})
Im getting an error if im not passing a string("abc123") or a const to it , can i pass a variable ? Test.name for example ?

2. hPyReturn=PYTHON Get Object FromAttribute(hPyClassInstance, "class_variable")
can i access method variable the same way i access class variables ?

Thanks again for all your hard work !

Idan

Re: ATEasy Python Driver

Hi Idan,

1.
You can index the avArgv and assign a variable to avArgv. This is done on line 4 of Test 1.8 with the Python client socket handle in avArgv[0].

2.
Depends on what namespace the variable is in:
- if variable is defined outside of function you can access
- if variable is defined in function's local namespace, the variable reference is dumped after invoke
- unless you return it or change its scope

Useful Python docs:
"
...
The local namespace for a function is created when the function is called, and deleted when the function returns or raises an exception that is not handled within the function
...
"
[ Source: https://docs.python.org/3/tutorial/classes.html#python-scopes-and-namespaces ]

Re: ATEasy Python Driver

Hello Tero,

when using hPyModule=PYTHON Module Import("C:\\GitRepos\\radar_validation_tools-atspy\\System\\TestsAPI\\FunTestMatrixATEasyAPI.py")
hPyModule return 0, where can i see why it failed to import the file ?

when i run it with python im not getting any errors.
using "python C:\\GitRepos\\radar_validation_tools-atspy\\System\\TestsAPI\\FunTestMatrixATEasyAPI.py"  in cmd there are no errors.

Tero

Re: ATEasy Python Driver

Hi Idan,

Module import uses PyImport_ImportModule() of the Python API.
[API, PyImport_ImportModule:
https://docs.python.org/3/c-api/import.html?#c.PyImport_ImportModule
]

It's not equivalent to running the interpreter from shell. The interpreter prints out exception if you are in TTY, so typing:
python {absoluteFilePath}
in cmd. And if there's an error, Python interpreter responds:
python: can't open file 'fileName': [Errno 2] No such file or directory

By default, the driver is initialized in *isolated mode, which means that it relies on you to tell it what environment you want to run your scripts in. I think this may be the reason why your module import fails: the script path isn't in sys.path list. You can add the path to TestsAPI in the driver PythonProjectPath. [Isolated mode:
https://docs.python.org/3/using/cmdline.html#id2
]

*It will however append to system path either the execution directory of the script or path in PythonProjectPath

Regards,
Tero
