###Userテスト

test/models/user_test.rb

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  def setup
    @user = User.new(name: "Example User", email: "[e-mail]",
                     password: "foobar", password_confirmation: "foobar")
  end

  test "should be valid" do
    assert @user.valid?
  end

  test "name should be present" do
    @user.name = ""
    assert_not @user.valid?
  end

  test "email should be present" do
    @user.email = "     "
    assert_not @user.valid?
  end

  test "name should not be too long" do
    @user.name = "a" * 51
    assert_not @user.valid?
  end

  test "email should not be too long" do
    @user.email = "a" * 244 + "@example.com"
    assert_not @user.valid?
  end

  test "email validation should accept valid addresses" do
    valid_addresses = %w[[e-mail] [e-mail] [e-mail]
                         [e-mail] [e-mail]]
    valid_addresses.each do |valid_address|
      @user.email = valid_address
      assert @user.valid?, "#{valid_address.inspect} should be valid"
    end
  end

  test "email validation should reject invalid addresses" do
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example.
                           foo@bar_baz.com foo@bar+baz.com]
    invalid_addresses.each do |invalid_address|
      @user.email = invalid_address
      assert_not @user.valid?, "#{invalid_address.inspect} should be invalid"
    end
  end

  test "email addresses should be unique" do
    duplicate_user = @user.dup
    duplicate_user.email = @user.email.upcase
    @user.save

  end

  test "password should be present (nonblank)" do
    @user.password = @user.password_confirmation = " " * 6
    assert_not @user.valid?
  end

  test "password should have a minimum length" do
    @user.password = @user.password_confirmation = "a" * 5
    assert_not @user.valid?
  end
end

#RSpec

###Userテスト

spec/models/user_spec.rb

require 'rails_helper'

RSpec.describe User, type: :model do

  before do
    @user = User.new(name: "Example User", email: "[e-mail]",
                     password: "foobar", password_confirmation: "foobar")
  end

  it "should be valid" do
     expect(@user).to be_valid
  end

  it "name should be present" do
    @user.name = ""
    @user.valid?
    expect(@user.errors[:name]).to include("can't be blank")
  end

  it "email should be present" do
    @user.email = ""
    @user.valid?
    expect(@user.errors[:email]).to include("can't be blank")
  end

  it "name should not be too long" do
    @user.name = "a"*51
    @user.valid?
    expect(@user.errors[:name]).to include("is too long (maximum is 50 characters)")
  end

  it "email should not be too long" do
    @user.email = "a" * 244 + "@example.com"
    @user.valid?
    expect(@user.errors[:email]).to include("is too long (maximum is 255 characters)")
  end

  it "email validation should accept valid addresses" do
    valid_addresses = %w[[e-mail] [e-mail] [e-mail]
                         [e-mail] [e-mail]]
    valid_addresses.each do |valid_address|
      @user.email = valid_address
      expect(@user).to be_valid
    end
  end

  it "email validation should reject invalid addresses" do
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example.
                           foo@bar_baz.com foo@bar+baz.com]
    invalid_addresses.each do |invalid_address|
      @user.email = invalid_address
      @user.valid?
      expect(@user.errors[:email]).to include("is invalid")
    end
  end

  it "email addresses should be unique" do
    duplicate_user = @user.dup
    duplicate_user.email = @user.email.upcase
    @user.save
    duplicate_user.valid?
    expect(duplicate_user.errors[:email]).to include("has already been taken")
  end

  it "password should be present (nonblank)" do
    @user.password = @user.password_confirmation = " " * 6
    @user.valid?
    expect(@user.errors[:password]).to include("can't be blank")
  end

  it "password should have a minimum length" do
    @user.password = @user.password_confirmation = "a" * 5
    @user.valid?
    expect(@user.errors[:password]).to include("is too short (minimum is 6 characters)")
  end

end

model specが自動で作成されていなければrails g rspec:model userで作成。
expect(@user.errors[:?]).to include("?")でエラーメッセージ、flashをテスト。
