first PR. Want to use this to familiarize with the process.

Let me know if there are specific rules for this project.

I followed instruction from development page.

Once this merged, I'll be able to contribute more.

Happy Friday.

Thanks Maarten!

I'll remove the test in component test.

And is there any specific reason we prefer Test() over under_test() or test()? As snakecase is the preferred convention. Pep8 will report otherwise.

urrr. I don't see components_test.py. Can you point out to me where is it?

[maartenbreddels]

I see it is never added to git 🙃 But we use the CamelCase because components are special functions, they are lazy, get re-executed, and contain state, which makes them behave more like classes.

just merged changes and please take a look
