pyhistorian is a BDD tool for writing specifications using Given-When-Then template
The goal of pyhistorian is to write an internal Given-When-Then template using Python. The ideas came from JBehave, RBehave, Cucumber and others.
It’s possible to write your stories in English and Portuguese, choose your preferred.
A good example of use [en-us, by default] follows (call this file calculator.py):
from should_dsl import * from pyhistorian import * class Calculator(object): def sum(self, n1, n2): return n1+n2 class SpecifyingMyNewCalculator(Story): """As a lazy mathematician I want to use a calculator So that I don't waste my time thinking""" colored = True template_color = 'yellow' scenarios = ['SumScenario'] # optional class SumScenario(Scenario): @Given('I have a calculator') def set_my_calculator(self): self.calculator = Calculator() @When('I enter with 1 + 1') def sum_one_to_one(self): self.result = self.calculator.sum(1, 1) @Then('I have $value as result', 2) def get_result(self, value): self.result |should_be| value if __name__ == '__main__': SpecifyingMyNewCalculator.run()
$ python calculator.py Story: Specifying my new calculator As a lazy mathematician I want to use a calculator So that I don't waste my time thinking Scenario 1: Sum of 1 and 1 Given I have a calculator ... OK When I enter with 1 + 1 ... OK Then I have 2 as result ... OK Ran 1 scenarios with 0 failures, 0 errors and 0 pending steps
