How do I use testify for assertions in Go?

You can use the testify package in Go to simplify your assertions. First, install it using go get github.com/stretchr/testify. Then, you can use functions like assert.Equal(t, expected, actual) to check if two values are equal.

Can you show me an example of using assert.Equal?

Sure! Here's a simple example:

package main

import (
    "testing"
    "github.com/stretchr/testify/assert"
)

func TestAddition(t *testing.T) {
    result := 1 + 1
    assert.Equal(t, 2, result, "1 + 1 should equal 2")
}

What other assertion functions does testify provide?

Testify provides several assertion functions like assert.NotNil, assert.True, assert.False, and assert.Contains, among others. Each function helps you validate different conditions in your tests.

Is there a way to use testify with table-driven tests?

Yes, you can use testify with table-driven tests by iterating over a slice of test cases and using the assertion functions within the loop. This approach keeps your tests organized and easy to read.
