Volkswagen is a satirical JavaScript package that makes your automated tests silently pass whenever they detect they are running on a CI server (a CI server, short for Continuous Integration server, is an automated system that runs tests on your code whenever you push changes, like Travis CI, CircleCI, or Jenkins). Named after the real Volkswagen emissions scandal in which cars used a "defeat device" to behave differently during official testing, this package works the same way: require it once in your test file, and it will detect the CI environment and suppress any test failures so the build always shows green. The project is openly framed as a joke and a commentary on the practice of gaming automated checks to show passing results without actually fixing problems. It supports detecting over a dozen well-known CI services by name, and also catches any environment that sets a standard CI environment variable. It can defeat failures from popular testing tools including assert, tap, tape, and chai, as well as any test that signals failure through an exit code. The package is installed via npm with a single command. It is MIT licensed and was inspired by a similar PHP package. The README suggests adding an "always passing" build badge to your project, the badge itself is, of course, a joke.
