Tox 运行 命令基于环境变量

Tox running command based on env variable

我当前的工作流程是 github 在 Travis CI 上测试的 PR 和构建,使用 tox 测试 pytest 并向 codeclimate 报告覆盖率。

travis.yml

os:
- linux
sudo: false
language: python
python:
- "3.3"
- "3.4"
- "3.5"
- "pypy3"
- "pypy3.3-5.2-alpha1"
- "nightly"
install: pip install tox-travis
script: tox

tox.ini

[tox]
envlist = py33, py34, py35, pypy3, docs, flake8, nightly, pypy3.3-5.2-alpha1

[tox:travis]
3.5 = py35, docs, flake8

[testenv]
deps = -rrequirements.txt
platform =
    win: windows
    linux: linux
commands =
    py.test --cov=pyCardDeck --durations=10 tests

[testenv:py35]
commands =
    py.test --cov=pyCardDeck --durations=10 tests
    codeclimate-test-reporter --file .coverage
passenv =
    CODECLIMATE_REPO_TOKEN
    TRAVIS_BRANCH
    TRAVIS_JOB_ID
    TRAVIS_PULL_REQUEST
    CI_NAME

但是,Travis 没有为拉取请求传递我的环境变量,这导致我的覆盖率报告失败。 Travis 文档将此显示为解决方案:

script:
   - 'if [ "$TRAVIS_PULL_REQUEST" != "false" ]; then bash ./travis/run_on_pull_requests; fi'
   - 'if [ "$TRAVIS_PULL_REQUEST" = "false" ]; then bash ./travis/run_on_non_pull_requests; fi'

但是,在 tox 中这不起作用,因为 tox 使用子进程 python 模块并且不能将 if 识别为命令(自然地)。

如何 运行 codeclimate-test-reporter 仅用于构建而不用于基于 TRAVIS_PULL_REQUEST 变量的拉取请求?我必须创建自己的脚本并调用它吗?有没有更聪明的解决方案?

您可以有两个 tox.ini 文件并从 travis.yml

调用它

script: if [ $TRAVIS_PULL_REQUEST ]; then tox -c tox_nocodeclimate.ini; else tox -c tox.ini; fi

我的解决方案是通过 setup.py 命令来处理所有事情

Tox.ini

[testenv:py35]
commands =
    python setup.py testcov
passenv = ...

setup.py

class PyTestCov(Command):
    description = "run tests and report them to codeclimate"
    user_options = []

    def initialize_options(self):
        pass

    def finalize_options(self):
        pass

    def run(self):
        errno = call(["py.test --cov=pyCardDeck --durations=10 tests"], shell=True)
        if os.getenv("TRAVIS_PULL_REQUEST") == "false":
            call(["python -m codeclimate_test_reporter --file .coverage"], shell=True)
        raise SystemExit(errno)
