pytest BDD 是一种基于 pytest 测试框架和 Gherkin 语言的 BDD 工具,它可以使测试用例更易读、易理解、易维护。通过 pytest BDD,我们可以使用类似于自然语言的语法来描述测试用例的场景和步骤。pytest BDD 还提供了一些特殊的命令和装饰器来辅助测试用例的编写和执行。

pytest bdd目录结构
When organizing pytest-bdd tests, you can follow a directory structure that makes it easy to manage and execute your BDD scenarios. Here's a common pytest-bdd directory structure:
```
project/
├── features/
│ ├── support/
│ │ ├── environment.py
│ │ └── steps/
│ │ └── step_definitions.py
│ ├── feature1.feature
│ └── feature2.feature
└── tests/
├── conftest.py
└── test_*.py
```
Let's break down each component of this directory structure:
- `features/`: This directory contains all the feature files (`*.feature`) that describe your BDD scenarios. Each feature file contains one or more scenarios with their corresponding steps.
- `features/support/`: This directory is used to store support code and configuration for your BDD tests.
- `features/support/environment.py`: This Python file is used to define the pytest-bdd environment. You can configure hooks, fixtures, and other settings here.
- `features/support/steps/`: This directory contains step definition files (`*_definitions.py`). Each step definition file defines the code implementation for the steps mentioned in the feature files.
- `tests/`: This directory is used to store any additional tests or test-related code that is not specific to BDD. For example, you might have unit tests or integration tests here.
- `tests/conftest.py`: This Python file is a pytest configuration file where you can define fixtures, plugins, and other test-related configurations.
- `tests/test_*.py`: These Python files contain additional tests that are not written using BDD. You can organize your tests into multiple files based on different test scenarios or test areas.
By following this directory structure, you can keep your BDD scenarios, step definitions, and other test-related code organized and easy to maintain. You can run your pytest-bdd tests by executing `pytest` in the root directory of your project, and pytest will discover and execute the tests based on this structure.
pytest-bdd
pytest-bdd是一个基于pytest框架的BDD(行为驱动开发)测试工具。BDD是一种软件开发方法,强调开发人员、质量保证和业务专家之间的协作,以确保测试覆盖了业务需求。
使用pytest-bdd,我们可以使用自然语言编写测试用例,这样测试用例就变得更易读、易维护。pytest-bdd提供了Gherkin语言的支持,Gherkin是一种用于描述系统行为的语言,类似于自然语言。这意味着我们可以使用类似于“Given-When-Then”的关键字编写测试场景。
pytest-bdd提供了丰富的装饰器和关键字,使得我们可以在测试用例中使用各种关键字和步骤来描述测试场景。它还支持参数化测试,允许我们为同一个场景编写多个具体的测试用例。
pytest-bdd还提供了与pytest框架的无缝集成,我们可以使用pytest的强大功能(如夹具、插件等)来扩展和优化我们的测试。
同时,pytest-bdd是一个开源项目,具有活跃的社区支持。这意味着我们可以轻松地找到解决问题的资源和帮助。
总之,pytest-bdd是一个强大而灵活的BDD测试工具,它能够帮助我们更好地协同开发人员和业务专家,提高测试用例的可读性和可维护性。它的无缝集成、强大的功能和开源的优势使得我们可以更轻松地构建和管理我们的测试套件。
