# gomonkey

gomonkey is a library to make monkey patching in unit tests easy, and the core idea of monkey patching comes from [Bouke](https://github.com/bouk), you can read [this blogpost](https://bou.ke/blog/monkey-patching-in-go/) for an explanation on how it works.

## Features

+ support a patch for a function
+ support a patch for a public member method
+ support a patch for a private member method
+ support a patch for a interface
+ support a patch for a function variable
+ support a patch for a global variable
+ support patches of a specified sequence for a function
+ support patches of a specified sequence for a member method
+ support patches of a specified sequence for a interface
+ support patches of a specified sequence for a function variable

## Notes
+ gomonkey fails to patch a function or a member method if inlining is enabled, please running your tests with inlining disabled by adding the command line argument that is `-gcflags=-l`(below go1.10) or `-gcflags=all=-l`(go1.10 and above).
+ A panic may happen when a goroutine is patching a function or a member method that is visited by another goroutine at the same time. That is to say, gomonkey is not threadsafe.
