$ export GOPATH=~/go$ go get github.com/stretchr/testify

And then you can see it under your Gopath directory.

I mainly use two bags

1. Assert package
2. Require package

The only difference is that the Require function directly causes the case to end, while the assert is marked as a case failure, but the case does not exit, but continues to execute. See an example:
Example 1: Using Assert

package mainimport (  "testing"  "github.com/stretchr/testify/assert" )func TestCase1(t *testing.T) {    name := "Bob"    age := 10    assert.Equal(t, "bob", name)    assert.Equal(t, 20, age)}

Perform:

$ go test          --- FAIL: TestCase1 (0.00s)        assertions.go:254:                         Error Trace:    main_test.go:13                        Error:          Not equal:                                         expected: "bob"                                        actual  : "Bob"                        Test:           TestCase1        assertions.go:254:                         Error Trace:    main_test.go:14                        Error:          Not equal:                                         expected: 20                                        actual  : 10                        Test:           TestCase1FAILexit status 1FAIL    testUT  0.009s

In this example we are using assert and we can see two assert. The Equal () instructions were executed.
Example 2: Using Require

package mainimport (  "testing"  "github.com/stretchr/testify/require")func TestCase1(t *testing.T) {    name := "Bob"    age := 10    require.Equal(t, "bob", name)    require.Equal(t, 20, age)}

Perform:

$ go test--- FAIL: TestCase1 (0.00s)        assertions.go:254:                         Error Trace:    main_test.go:12                        Error:          Not equal:                                         expected: "bob"                                        actual  : "Bob"                        Test:           TestCase1FAILexit status 1FAIL    testUT  0.007s

And in this case we are using require, and we can see only the first require. The Equal () instruction was executed, the second require. Equal () was not executed.
