Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why does Rusts testing tools seem so much less polished compared to its other tooling?
Testing tools on the JVM stopped using reflection about twenty years ago, they all use annotations these days (e.g. https://testng.org, https://junit.org). Rust has annotations too, obviously.

Reassessing TestNG vs. Junit
Recently though we've run across a few issues with the asserts in TestNG. In 7.3.0, some changes broke assertSame/assertNotSame that also broke some of our tests. This was partially fixed in 7.4.0, but some overloads of assertEquals were still broken. This is fixed, but I don't think the fix has been delivered in a release yet. Further investigation revealed that at least one overload of assertNotEquals has been broken, apparently since 6.9.5 or even earlier.

Unit Testing Expo Apps With Jest
console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation
