GopherCon 2017: Mitchell Hashimoto - Advanced Testing with Go

[@catallergiccat]

The way how I prevent 200 lines for preparing test fixture is using test fixture builder. The builder builds test fixture with default values, however can specify case-by-case fixture with "withX" functions, which saves a lot of lines of repeatedly code but still get to the point of the fixture.

[@catallergiccat]

Cannot agree with having testing purpose code such as "Test bool" in main code is a great idea. 30:45

[@silentassassin8959]

Awesome video! More people need to watch this

[@NovikArthur]

7:50 an error in example. Should be "tc.Expected" instead of "expected".

[@zhangjimmy6619]

Great! my testing code is bad to compare with this

[@mbigras]

At kzbin.info/www/bejne/bpm0eGqHoch_eM0 the plus sign + is the repetition operator, putting it in quotes solves the probably go test -v -run TestAdd/"\+1"

[@nicocesar]

14:12 he mentions a good way to show Diff(actual, expected) ... but I can't understand what library he is referring to. Anyone has a clue?

[@tracefindertracefinder7215]

Perhaps, it's about pkg.go.dev/github.com/google/go-cmp/cmp#Diff

[@pulsarglider]

go-cmp package

[@aaronyu]

Does anyone know where can I get the slides? Cause I can not understand the content that quickly... Thanks a lot.

[@ppang]

Use pause, period.

At 16:00, What does t.Helper() do? I don't see it in the testing docs.

[@ashishacharya4001]

Helper() is a new method added in 1.9. tip.golang.org/doc/go1.9#test-helper

[@aclshumway]

It was added in 1.9 golang.org/pkg/testing/#T.Helper

[@sashimi80]

tells to the testing env that the function is an Helper and not a real test function.
