Usage

Here is an example scenario demonstrating how to decode a base64 encoded string:

# ./scenarios/decode_base64_encoded_string.py
import vedro
from base64 import b64decode
from d42 import schema

class Scenario(vedro.Scenario):
    subject = "decode base64 encoded string"

    def given(self):
        self.encoded = "Y3VjdW1iZXI="

    def when(self):
        self.result = {
            "result": b64decode(self.encoded)
        }

    def then(self):
        assert self.result == schema.dict({
            "result": schema.bytes(b"banana")
        })

Run the test using the command:

$ vedro run

If the expected and actual results don't match, a ValidationException will be raised, as illustrated below:

ValidationException:
 - Value <class 'bytes'> at _['result'] must be equal to b'banana', but b'cucumber' given
