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.

What's your favourite part of unit testing?
I also use BDD (Gherkin with godog in particular) to verify and document the expected behaviour of a product from an end user's perspective when needed. I usually do this when the product also contains untested code that I have no control over when I'm working on a problem - this gives me peace of mind over something I can't control while doubling as documentation.

Behaviour Driven Development (BDD) boilerplate tests generator
It looks like it is not possible to share steps between scenario's or features. In https://github.com/cucumber/godog it is possible to share steps.

Visualizing Diffs The Myers difference algorithm
This made me think of a couple other interesting things:
1. you can change which algorithm is used in git diff as multiple are supported

2. Google has an edit graph implementation in Go in the cmp package

How do you do DB preparation in e2e tests?
Assertion libraries that people seem to love: - testify (my favorite) - go-cmp is a more barebones library - gotest.tools -- I have never used this but some swear by it

alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
it uses https://github.com/google/go-cmp instead of reflect.DeepEqual

What annoys you about Go?
When I use functional arguments, I either prefix all of the options with the same prefix or put them in a dedicated package (like cmpopts) to help the IDE.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

Go Package for Equality: github.com/google/go-cmp
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.
