Requirements

You will need the following prerequisites in order to use pytest-variables:

  • Python 2.7, 3.6, PyPy, or PyPy3
  • pytest 2.6 or newer

Installation

To install pytest-variables:

$ pip install pytest-variables

Additional formats

The following optional formats are supported, but must be explicitly installed as they require additional dependencies:

Human JSON

Human JSON is a configuration file format that caters to humans and helps reduce the errors they make. To install Human JSON support:

$ pip install pytest-variables[hjson]

YAML

YAML is a human friendly data serialization standard for all programming languages. To install YAML support:

$ pip install pytest-variables[yaml]

Specifying variables

Use the –variables command line option one or more times to specify paths to files containing your variables:

$ pytest --variables firefox-53.json --variables windows-10.json

with the following contents for the firefox-53.json file:

{
  "capabilities": {
    "browser": "Firefox",
    "browser_version": "53.0"
  }
}

and another file named windows-10.json with:

{
  "capabilities": {
    "os": "Windows",
    "os_version": "10",
    "resolution": "1280x1024"
  }
}

you’ll get the merged version of your variables:

{
  "capabilities": {
    "browser": "Firefox",
    "browser_version": "53.0",
    "os": "Windows",
    "os_version": "10",
    "resolution": "1280x1024"
  }
}

If multiple files are specified then they will be applied in the order they appear on the command line. When duplicate keys with non dictionary values are encountered, the last to be applied will take priority.

Accessing variables

With a JSON variables file such as:

{
  "foo": "bar",
  "bar": "foo"
}

Specify the variables funcarg to make the variables available to your tests. The contents of the files are made available as a dictionary:

def test_foo(self, variables):
    assert variables['foo'] == 'bar'
    assert variables.get('bar') == 'foo'
    assert variables.get('missing') is None
