Argument of type 'Element' is not assignable to parameter of type 'ReactElement<any>

If you have JSX inside your component or component test file must have .tsx as your file extension. My code was not compiling as I had the .ts file extension. The moment I renamed it to .tsx/jsx it started working nicely!

Please also note that I was using Typescript, so that's why I renamed it to .tsx. In case you are using ES6 rename it to .jsx.

This is apparently an issue which was introduced in the 15.0.5 React type definitions. If you change to 15.0.4, everything should be fine.
