Adding this in `dev-cmd/ruby.rb` allows us to suppress warnings like:
```
/home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/language/python.rb:8: warning: Insecure world writable dir /home/linuxbrew/.linuxbrew/Homebrew/Library/Homebrew/shims/scm in PATH, mode 040777
```
This ensures that dependencies are verified and tapped before they are
fetched. `FormulaInstaller#lock` has been moved into
`FormulaInstaller#install` to avoid locking until necessary.
While we're here, don't compute dependencies before fetching if we're
not going to use them.
This commit fixes a flaw in the Cask test helper, causing the broken `Cask::Config` test to actually fail.
The flaw occurred while patching the `Cask::Config::DEFAULT_DIRS` hash.
While the original hash uses strings as values, the patched one used
`Pathname` values, masking a broken `Cask::Config::from_json` test.
Now the broken test fails like it should.
There appear to be random, seemingly impossible to debug issues with
running integration tests on portable Ruby. Instead of confusing
contributors when these will be run on CI anyway: let's just skip them
by default (like we do with `--online` for online tests anyway).
- This also required auto-fixes for Layout/EmptyLinesAroundBlockBody and
Layout/InconsistentIndentation once the auto-fixer had got rid of the
"redundant begin"s.
Integration tests are useful in detecting breakages but much slower so
let's only use one per command and install formula outside the
integration test framework (which is also slow).
In a number of Cask specs, the value of the `homepage` stanza is currently set
to https://example.com. As of 2018-11-28, the TLS certificate served by
example.com seems to be expired, possibly due to an oversight on ICANN’s side.
While the certificate is certainly going to be renewed soon, it would be
desirable for Homebrew’s test result to be less dependent on ICANN’s actions.
This commit changes the homepages of all test Casks to http://brew.sh, whose
domain and TLS certificate are both controlled by Homebrew.
In Cask specs, we have recently introduced a couple of specialized
`shared_examples` directories. Those new directories are organized
below their respective packages (for instance,
`cask/artifact/shared_examples` and `cask/cmd/shared_examples`).
This commit moves the rest of the shared examples accordingly.
