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.

Working with JSON in Go: A Comprehensive Guide
And do not forget to use go-testdeep and its JSON operator to test JSON content: :)

Libraries you use most of your projects?
TestDeep. I got pretty used to many of the matchers and they simplify my life now.

Large repo switched to new go1.19 doc comments
To see the result on a large repository, I adapted the comments of go-testdeep to fully take advantage of these new features.
-
reflect.DeepEqual return false for two identical maps of any
Check also go-testdeep → https://goplay.tools/snippet/KgoeGR1bIwT the full featured testing framework... (not related to go-test/deep)

Patterns for unit testing in Go?
Check go-testdeep using its operators, it is very easy to do table driven tests, see https://goplay.space/#Z91D72aH3Sc for an example

go-testdeep v1.10.0 then v1.10.1 released with many new features!
the 1.10.0 release with many new features including a new SuperSliceOf operator (so now 62 operators!), a relaxed JSON parser, the possibility to ignore unexported struct fields, to target a specific nested field (even private), the enhancement of tdhttp HTTP API tester to check cookies, to use multipart/form-data bodies, and many other magic things…

Do you prefer go-convey over golang's t.Run?
And of course go-testdeep which colorizes the error reports with simple but accurate diff.
