* Since we lock our dependencies in the `yarn.lock` file, we need to enforce that the lock file is in sync with the `package.json` file (similar as in angular/angular) * Since we cache the dependenices & the yarn cache within Travis, it can happen that the node modules are stale (there is no checksum mechanism in Travis). In that case we need to purge the node modules and re-install.

# 1) Cached node modules are not in sync with lock file
|

# 2) Lock file is not in sync with `package.json`

# In case the integrity check passes, we just use the cached/locked node modules. If it fails, we want to purge the

# node modules and run Yarn with `--frozen-lockfile`. Running with a frozen lockfile ensures that outdated/cached node
|
|
# modules will be refreshed to **match** the actual lock file. Otherwise, if the `package.json` does not match with
|
|
# the lock file, Yarn automatically throws an error due to the `--frozen-lockfile` option.
