比較使用 eq (==)

RSpec.describe "a string" do
  it "is equal to another string of the same value" do
    expect("this string").to eq("this string")
  end

  it "is not equal to another string of a different value" do
    expect("this string").not_to eq("a different string")
  end
end

RSpec.describe "an integer" do
  it "is equal to a float of the same value" do
    expect(5).to eq(5.0)
  end
end

當我執行 rspec 然後輸出應該包含“3 個例子，0 個失敗”

比較使用 ==

RSpec.describe "a string" do
  it "is equal to another string of the same value" do
    expect("this string").to be == "this string"
  end

  it "is not equal to another string of a different value" do
    expect("this string").not_to be == "a different string"
  end
end

RSpec.describe "an integer" do
  it "is equal to a float of the same value" do
    expect(5).to be == 5.0
  end
end

比較使用 eql (eql?)

 RSpec.describe "an integer" do
  it "is equal to another integer of the same value" do
    expect(5).to eql(5)
  end

  it "is not equal to another integer of a different value" do
    expect(5).not_to eql(6)
  end

  it "is not equal to a float of the same value" do
    expect(5).not_to eql(5.0)
  end
end
