Expected Behavior

render function works without crashing

Link to Code

lithoViewRule.render { CustomComponent() }

Unfortunately as Yoga is a native dependency, getting it to work with local unit tests with gradle is a pain. The best suggestion is to follow something similar to the setup in this project itself:

1) Copy lib/yoga and lib/yogajni in your project 2) Add this to your settings.gradle and something like this to your root build file (you may want to make a LithoTest type) 3) Add a switch to include the yogajni dep for non-release builds like this

Alternately, if easier, you could clone the yoga repo, build Yoga targeting your required architecture, and then add the library to your classpath manually (as done here: https://github.com/facebook/litho/blob/master/build.gradle#L98-L111)
