From: Lars Schneider <redacted> The Travis-CI machines are in a clean state in the beginning of every run (transient by default). Use the Travis-CI cache feature to make the prove state persistent across consecutive Travis-CI runs on the same branch. This allows to run previously failed tests first and run remaining tests in slowest to fastest order. As a result it is less likely that Travis-CI needs to wait for a single test at the end which speeds up the test suite execution by ~2 min. Travis-CI can only cache entire directories. Prove stores the .prove file always in the t/ directory but we don't want to cache the entire t/ directory. Therefore we create a symlink from $HOME/travis-cache/.prove to t/.prove and cache the $HOME/travis-cache directory. Unfortunately the cache feature is only available (for free) on the Travis-CI Linux environment.
Thanks. I wouldn't be confused with the above description like before. I see systems other than Linux listed in os: section; presumably our $HOME would not persist and we wouldn't even have $HOME/travis-cache directory when we run on them, so "mkdir -p" would be both necessary and save to have whether the "cache" feature is available or not. And the "ln -s" would be the same way--either we symlink to a file that hasn't been born (either on a platform without "cache" feature, or the first run on Linux) and that is perfectly fine. And all the systems listed in os: section supports symlinks, so the "mkdir -p && ln -s" is safe. Looks sensible. Thanks.
