Learn Go with Tests

https://github.com/quii/learn-go-with-tests

Sections

Sum:

• Use reflect.DeepEqual to compare arrays/slices

Repeat:

• Write benchmark test with func BenchmarkFuncname(b *testing.B)
• Run with go test -bench=.

Wallet:

• Use errcheck to detect what errors are not covered by tests

Map:

• Maps are reference types - so never initialize an empty map variable var m map[string]string. Instead initialize it or use make: map[string]string{} or make(map[string]string)
• Constant errors with custom DictionaryErr type
