該当のソースコード

以下のテストを走らせました。

require 'test_helper'

class ArticlesControllerTest < ActionController::TestCase
  test "index" do
    5.times { FactoryGirl.create(:article) }
    get :index
    assert_response :success
    assert_equal 5, assigns(:articles).count
  end

  test "show" do
    article = FactoryGirl.create(:article, expired_at: nil)
    get :show, params: { id: article.id }
    assert_response :success
  end

  test "new" do
    get :new
    assert_response :success
  end

  test "edit" do
    article = FactoryGirl.create(:article)
    get :edit, params: { id: article.id }
    assert_response :success
  end

  test "create" do
    post :create, params: { article: FactoryGirl.attributes_for(:article) }
    article = Article.order(:id).last
    assert_redirected_to article
  end

  test "update" do
    article = FactoryGirl.create(:article)
    patch :update, params: { id: article.id, article: FactoryGirl.attributes_for(:article) }
    assert_redirected_to article
  end

  test "fail to create" do
    attrs = FactoryGirl.attributes_for(:article, title: "")
    post :create, params: { article: attrs }
    assert_response :success
    assert_template "new"
  end

  test "fail to update" do
    attrs = FactoryGirl.attributes_for(:article, body: "")
    article = FactoryGirl.create(:article)
    put :update, params: { id: article.id, article: attrs }
    assert_response :success
    assert_template "edit"
  end
end

試したこと

こちらに書かれたことは試しましたが、エラーメッセージは変わらぬままでした。

補足情報（FW/ツールのバージョンなど）

Rails 6.0.2.1
Ruby 2.5.0
Minitest (5.14.0, 5.10.3)

articlesのDBの定義は以下です。

class CreateArticles < ActiveRecord::Migration[6.0]
  def change
    create_table :articles do |t|
      t.string :title, null: false                        #タイトル
      t.text :body, null: false                           #本文
      t.datetime :released_at, null: false                #掲載開始日時
      t.datetime :expired_at                              #掲載終了日時
      t.boolean :member_only, null: false, default: false #会員のみフラグ
      t.timestamps null: false
    end
  end
end

皆さまからの質問などは分からないなりに調べてご返信致します。何か不足した情報などがありましたら教えて頂ければと思います。何卒宜しくお願い致します。

Answer 1

Railsはやったことがないので、間違っているかもですが。
minitest のバージョンが新しすぎるのではないでしょうか？

以下の active support の変更を見る限り、

https://github.com/rails/rails/commit/268a099b1b8ad6aa58e52a100d4201f253663feb

activesupport 6.0.2.1 は minitest 5.14 は未対応みたいです。

返信が遅くなってしまい、大変申し訳ありませんでした。railsでプロジェクトを作るとminitestが自動で入ってくるのですが、可能であれば別のバージョンのminitestをインストール出来ないか試してみます。
