Hey test-driven developers: these mods let you take a page from Volkswagen’s book and pass all tests, no matter what!

Inspired by the recent scandal in which Volkswagen programmed the engines in their cars to detect if they were undergoing an emissions test and alter their behavior so that they’d pass, a couple of developers have created modules that enable your test suite to detect if they’re running on a continuous integration server , and if that’s the case, report all tests as passing. Think of all the time you could save!

PHPUnit VW Extension

phpunit-vw checks for the commonly-used continuous integration tools’ default environment variables, and ensures that all unit tests pass if it detects the presence of any of these:

If your CI tool isn’t in the list, but makes use of environment variables commonly used by test suites (such as BUILD_ID), phpunitvw might work with it.

…as well as any server that exposes an environment variable like CI or CONTINUOUS_INTEGRATION.

Why should Volkswagen have all the fun? Get these add-ons and start passing tests with flying colors today!
