背景

先看看 @scenario 的源码

  2. def scenario(feature_name: str, scenario_name: str, encoding: str = "utf-8", features_base_dir=None):
  3.     """Scenario decorator.
  5.     :param str feature_name: Feature file name. Absolute or relative to the configured feature base path.
  6.     :param str scenario_name: Scenario name.
  7.     :param str encoding: Feature file encoding.
  8.     """

再看看怎么使用 @scenario

  1. @scenario("publish_article.feature", "Payments - Check off-chain payment for checkout via Main App")
  2. def test():
  3.     pass

重点

  • 当你使用 @scenario 的时候，如果一个 Feature 有多个 Scenario 时，就要写多个 @scenario
  • 然后 feature_name 就要重复写，挺麻烦的，为了解决这个痛点，可以使用 functools.partial

没使用 partial 之前

  1. from pytest_bdd import scenario
  3. @scenario("publish_article.feature", "Payments - Check off-chain payment for checkout via Main App")
  4. def test():
  5.     pass
  8. @scenario("publish_article.feature", "Payments - Check off-chain payment in CRO/BTC/ETH/TUSD/USDC/USDT")
  9. def test():
  10.     pass

使用 partial 之后

  1. from functools import partial
  2. import pytest_bdd
  4. scenarioa = partial(pytest_bdd.scenario, "publish_article.feature")
  6. @scenarioa("Payments - Check off-chain payment for checkout via Main App")
  7. def test1():
  8.     pass
  11. @scenarioa("Payments - Check off-chain payment in CRO/BTC/ETH/TUSD/USDC/USDT")
  12. def test2():
  13.     pass

感觉并不好用，还有 bug，不推荐使用
