試したこと

DBの作り直しとgumインストール等してみましたが変化なしでした…

$ rails db:drop
$ rails db:create
$ rails db:migrate

変化なし

$rake db:migrate:reset
$rails db:migrate

$bundle install
$bundle update

 $ sudo yum install -y tmux

Answer 1

すみません自己解決しました。
test "" do　が抜けていました…

 test "" do
      @user.password = @user.password_confirmation = " " * 6
      assert_not @user.valid?
   end

   test do
       @user.password = @user.password_confirmation = "a" * 5
       assert_not @user.vaild?
       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
