# Deep Variable Equality for Humans

This package provides a single function: `deep.Equal`. It's like [reflect.DeepEqual](http://golang.org/pkg/reflect/#DeepEqual) but much friendlier to humans (or any sentient being) for two reason:
|
|
|
|
* `deep.Equal` returns a list of differences
|
|
* `deep.Equal` does not compare unexported fields (by default)
|
|
|
|
`reflect.DeepEqual` is good (like all things Golang!), but it's a game of [Hunt the Wumpus](https://en.wikipedia.org/wiki/Hunt_the_Wumpus). For large maps, slices, and structs, finding the difference is difficult.
|
|
|
|
`deep.Equal` doesn't play games with you, it lists the differences:
|
|
|
|
```go
|
|
package main_test
|
|
|
|
import (
|
|
"testing"
|
|
"github.com/go-test/deep"
|
|
)
|
|
|
|
type T struct {
|
|
Name string
|
|
Numbers []float64
|
|
}
|
|
|
|
func TestDeepEqual(t *testing.T) {
|
|
// Can you spot the difference?
|
|
t1 := T{
|
|
Name: "Isabella",
|
|
Numbers: []float64{1.13459, 2.29343, 3.010100010},
|
|
}
|
|
t2 := T{
|
|
Name: "Isabella",
|
|
Numbers: []float64{1.13459, 2.29843, 3.010100010},
|
|
}
|
|
|
|
if diff := deep.Equal(t1, t2); diff != nil {
|
|
t.Error(diff)
|
|
}
|
|
}
|
|
```
|
|
|
|
|
|
```
|
|
$ go test
|
|
--- FAIL: TestDeepEqual (0.00s)
|
|
main_test.go:25: [Numbers.slice[1]: 2.29343 != 2.29843]
|
|
```
|
|
|
|
The difference is in `Numbers.slice[1]`: the two values aren't equal using Go `==`.
