The write once, test everywhere pattern
Jeff Roggers and Kristan Vingrys initially developed the write once, test everywhere pattern while working at ThoughtWorks. The concept centers on taking advantage of shared behavior between multiple implementations of one application. For example, it should be possible to purchase a product from our website no matter whether the user is using our full website, the mobile version, or native mobile application. If the feature definitions are well written, the steps used to implement the test can be interchangeable.
Note
The write once, test everywhere pattern is also known as the pluggable test pattern, since we can plug the implementation of tests into different contexts. As we change the context from the desktop website to mobile to API tests, we plug in the correct implementation.
Advantages of the write once, test everywhere pattern
The write once, test everywhere pattern has several advantages going for it; here is a list of a few of them:
