基于env变量的Tox运行命令

Question

我目前的工作流程是在Travis CI上测试github PRs和Builds，使用tox测试pytest并将报告覆盖率报告给codeclimate。

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没有将我的环境变量传递给pull请求，这使我的覆盖报告失败。 Travis文档显示了这个解决方案：

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正在使用子进程python模块，并且无法识别是否作为命令（自然地）。

如何仅针对构建运行codeclimate-test-reporter而不针对基于TRAVIS_PULL_REQUEST变量的pull请求运行？ 我是否必须创建自己的脚本并调用它？ 有更聪明的解决方案吗？

Answer 1

您可以拥有两个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

Answer 2

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)

 ...


  cmdclass={'testcov': PyTestCov},
