vedro-d42-validator 1.4.0

Vedro plugin for integrating d42 schema validation

Vedro D42 Validator

This plugin integrates d42 schema validation into the Vedro testing framework, providing enhanced schema validation and error handling capabilities during test execution.

Installation

Quick

For a quick installation, you can use a plugin manager as follows:

$ vedro plugin install vedro-d42-validator

Manual

To install manually, follow these steps:

1. Install the package using pip:

$ pip3 install vedro-d42-validator

2. Next, activate the plugin in your vedro.cfg.py configuration file:

# ./vedro.cfg.py
import vedro
import vedro_d42_validator

class Config(vedro.Config):

    class Plugins(vedro.Config.Plugins):

        class D42Validator(vedro_d42_validator.D42Validator):
            enabled = True

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
