Aunit test returning blocked for given Sample Apama Projects

Question

I am trying to use AUnit for Unit testing in apama. So I checked and read tha Aunit package uses Apama Pysys in the backend to test Apama application.

While I was successful in building the Aunit package , I am getting an error in testing the sample Apama monitors given with it. I am continuously getting the Warning:

The error seems to be from line 27 of https://github.com/antoinewaugh/aunit/blob/master/test-build/template/run_fast.py.template and looks like a python 2 vs 3 compatibility thing. So the quickest way to get this working for you might be to try running it with Python 2 (if Antoine hasn’t yet added support for Python 3 in AUnit)?

Or for a more long-term approach maybe try Caribou's fix to AUnit and if it works submit a pull request to get it incorproated?

I did think of the 2 vs 3 string issue but I didn't dig into the code - good spot — Caribou, Feb 27 '19 at 18:06

Without any code to look at and understand what you are doing, it looks to me like either the file being read (the csv) is in an unexpected encoding.

If you are opening the file at some point you need to make sure that it is read with the correct encoding or opened as a text file (I used utf8 below but if that doesn't work you may need to work out what encoding it is.

csvfile  = open('my.csv', "rt", encoding='utf8')

If you are not opening the file, and the open is happening within the library, then it could still be a bad encoding of what is being read - perhaps the data should be utf8 but it's some windows format?

you'll need to add code to the question so we can examine what is going on properly however if neither of these solves the issue.

The file i am trying to test is provided as a sample with AUnit package. The file opening is done by the script iteself i did not change anything in it. I updated the code block in my question just to show in detail what command i executed and the response i get. — Balpreet Singh, Feb 27 '19 at 13:50
Then I suspect you'll need to talk to the auther of the repo on github... — Caribou, Feb 27 '19 at 14:02

Aunit has been patched to support both versions of python (2 & 3).

Thanks for raising the issue.

Pull requests on the project are also welcome.
