shell - Travis-CI 和 Shell 脚本

Question

我使用 shunit2 在 shell script 上执行一些单元测试.

为了能够访问脚本的函数，我获取了它

. script_file.sh  --source-only

在脚本中，我将所有内容都封装在一个函数中，除了

if [ "${1}" != "--source-only" ]; then
    main "${@}"
fi

这适用于 Linux 和 OS X。我现在已经使用以下 .travis.yml

设置了 Travis CI

language: bash

before_script:
    - curl -L "http://downloads.sourceforge.net/shunit2/shunit2-2.0.3.tgz" | tar zx
    - chmod +x $(pwd)/shunit2-2.0.3/src/shell/shunit2

script:
    - export SHUNIT2=$(pwd)/shunit2-2.0.3/src/shell/shunit2
    - make test

Travis CI I see

虽然脚本上面的几行清楚地表明情况并非如此，但似乎调用了不带参数的脚本

+. ../check_ssl_cert --source-only

我错过了什么吗？

Travis 很可能在其 /bin/sh 中使用 其他 的 shell 而不是 bash . 的解释器和参数/source运算符不是 POSIX specified而且那个 shell 显然不支持它们。
