Variable Passing: int about tavern HOT 14 CLOSED

Have a look at the type conversions section of the docs.

You can use the !int operator (note the single !) here:

owner-id: !int "{owner-id:d}"

from tavern.

Hey Birne94,

Thank you so much for taking a look!

I forgot to include that scenario. Here is the output produced:

If I'm doing something outside the expected please let me know or if there is any config information I can pass over to get this figured out.

Thanks!

Which version of tavern are you using? The feature was just added in a recent release. Try upgrading the package.

pip install --upgrade tavern should do it, if I am not mistaken.

from tavern.

You're absolutely right. That is my mistake. I was using the most recent version on Pypi, which at the time was 0.5.4. I have updated to 0.7.1 and casting is working as expected! I apologize for being behind!

Thanks!

from tavern.

Hello kind folk at Tavern!

It seems like there has been a resurgence in the issue of casting ints using the "!int '{value:d}'" syntax. This is running version tavern-0.9.2 (which is also available in the logs).

Might you all know why this is happening again? Something to note, is in test_regression_get_collection.tavern.yaml this line:
collection-url: "/collections/{createdCollectionID:d}"
works without issue, however,
collection-id: !int '{createdCollectionID:d}'
receives an error

Thanks!

Hi,
I have the same issue with 0.9.3 version:
yaml.constructor.ConstructorError: could not determine a constructor for the tag '!int'
in "leads.yaml", line 82, column 24

from tavern.

After upgrading to 0.9.4 now I get different error:

request:
revision_id: !int "{revision_id:d}"

ValueError: invalid literal for int() with base 10: '{revision_id:d}'

revision_id is variable saved from previous response

from tavern.

There was an error with the type conversions that should be fixed in 0.9.5 (whenever it gets release on Travis), but I'm not sure what you mean when you say it was saved from the previous response - could you give an example of what you're trying to do?

from tavern.

I mean I use multistage testing, and saved values like this:

save:
        body:
          revision_id: id

from tavern.

Ah, sorry I completely misread you. I think this is the same issue as #85, I've left a comment there explaining that you need to convert the value when you use it in a subsequent test

from tavern.

Even with version 0.9.5 I get the same error:

There is a test for saving and converting types here: https://github.com/taverntesting/tavern/blob/master/tests/integration/test_typetokens.tavern.yaml#L308-L336

I think I need to see more of your code before figuring out why it's not working

from tavern.

Hi,
can we save a header returned in a response into a common.yml file or any other file which i can reuse in different test?
Declaring variable within test works, but since within test different test names are not reported in html reports.
