 * If the formula is a library, compile and run some simple code that links against it. It could be taken from upstream's documentation / source examples. A good example is [`tinyxml2`](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/t/tinyxml2.rb)'s test, which writes a small C++ source file into the test directory, compiles and links it against the tinyxml2 library and finally checks that the resulting program runs successfully.
 * If the formula is for a GUI program, try to find some function that runs as command-line only, like a format conversion, reading or displaying a config file, etc.
 * If the software cannot function without credentials or requires a virtual machine, docker instance, etc. to run, a test could be to try to connect with invalid credentials (or without credentials) and confirm that it fails as expected. This is preferred over mocking a dependency.

 What both methods have in common is that they are setting the correct environment for using npm inside Homebrew and are returning the arguments for invoking `npm install` for their specific use cases. This includes fixing an important edge case with the npm cache (caused by Homebrew's redirection of `HOME` during the build and test process) by using our own custom `npm_cache` inside `HOMEBREW_CACHE`, which would otherwise result in very long build times and high disk space usage.
