Test Types

1. Unit Tests

Basic unit tests for individual functions:

// Source: user.go
package service

type User struct {
    ID    string
    Email string
    Age   int
}

func (u *User) IsAdult() bool {
    return u.Age >= 18
}

func ValidateEmail(email string) error {
    if !strings.Contains(email, "@") {
        return errors.New("invalid email format")
    }
    return nil
}

// Generated: user_test.go
package service

import (
    "testing"
)

func TestUser_IsAdult(t *testing.T) {
    t.Run("adult user", func(t *testing.T) {
        user := &User{Age: 25}
        if !user.IsAdult() {
            t.Error("expected user to be adult")
        }
    })

    t.Run("minor user", func(t *testing.T) {
        user := &User{Age: 15}
        if user.IsAdult() {
            t.Error("expected user to be minor")
        }
    })

    t.Run("edge case - exactly 18", func(t *testing.T) {
        user := &User{Age: 18}
        if !user.IsAdult() {
            t.Error("18 year old should be adult")
        }
    })
}

func TestValidateEmail(t *testing.T) {
    tests := []struct {
        name    string
        email   string
        wantErr bool
    }{
        {
            name:    "valid email",
            email:   "[email protected]",
            wantErr: false,
        },
        {
            name:    "invalid email - no @",
            email:   "userexample.com",
            wantErr: true,
        },
        {
            name:    "empty email",
            email:   "",
            wantErr: true,
        },
    }

    for _, tt := range tests {
        t.Run(tt.name, func(t *testing.T) {
            err := ValidateEmail(tt.email)
            if (err != nil) != tt.wantErr {
                t.Errorf("ValidateEmail() error = %v, wantErr %v", err, tt.wantErr)
            }
        })
    }
}
