Calling 3rd party packages from scripts written in Python

[matju]

Hello,

I'm trying to import external 3rd party packages from my scripts written in Python language. Is there a way to use Python installed in different folder? I was trying to use default "site-packages" folder - I added 3rd party package to the folder, also copied whole content, installed it from commad line (by using PIP) and tried to call it from script, but TestComplete shows: "no module named requests".

I wrote in script also:

from os import sys
sys.path.append("C:\Data\Python\Lib\site-packages")

and then try to import 3rd party module, but there's also no effect. I don't want to use PyUnit, so is there any way to load 3rd party package in TestComplete in scripts?

Best Regards,

matju

TestComplete installs it's own python instance so the third-party package in the site-packages folder won't work. If you copy the third-party package you want from the site-packages into the TestComplete python folder it will work.

For example I use the pytz and tzlocal packages. After installing through pip, I copied those folders from the site-packages folder into C:\Program Files\SmartBear\TestComplete 11\Bin\Extensions\Python\Python34\Lib . Then just import like regular and it should work.

I think you could also add the site-packages folder to the sys path like you are in your code, I think the mistake you are making is not escaping the backslash character in your string or using a raw string. So it should be sys.path.append("C:\\Data\\Python\\Lib\\site-packages") or sys.path.append(r"C:\Data\Python\Lib\site-packages")

But i still encounter error:

ImportError

No module named 'win32com' 

i have copy site-packages from C:\Program Files (x86)\Python36-32\Lib\site-packages  to C:\Program Files (x86)\SmartBear\TestComplete 12\Bin\Extensions\Python\Python34\Lib\site-packages

but seem not working. when i try to import:

import win32com.client as win32

[ghuff2]

Did you copy your entire site-packages folder or just the win32com folder? You don't want the whole site-packages folder, only the folder of the third party package should go in the Lib folder, i.e. only copy the win32com folder into Lib, not entire site-packages.

Thanks, i copied the win32com folder to Lib only now. but another error pops when i run the script

ImportError No module named 'win32api'

Error location: Unit: "HorizonTestSuite\HorizonAutoTest\Script\genfuncs"

Line: 7 Column: 1.

It is weird since i didn't use win32api, my script only import win32com.client

import win32com.client as win3

Hi,

I'm not a Python guy and don't have TC at hand as we speak, so just a wild guess: I believe that win32api is referenced from win32com module. Have you checked if there is win32api folder within site-packages one and have you copied it to lib\ folder for TestComplete?

[danalu]

Thank you. Still not work. Anyway, i've tried use OLE now. Need re-write my code.

You need to copy all related folders from site-packages to Lib folder as suggested. You can check by date and time you installed your win32. Unless all related folder copy, you will see those type of errors.
