你应该干燥代码以最大程度地减少重复。你可以将每次测试开始时调用的指令移动到before，并为重复的代码提取帮助方法：
describe "Signup" do
before do
visit signups_path
end
def fill_form(fields = {})
fields.each do |field_name, field_value|
fill_in field_name.to_s.capitalize, with: field_value
end
click_button "Signup"
end
it "informs user of an invalid email" do
fill_form email: ""
expect(page).to have_text("Email can't be blank")
end
it "informs user of an invalid password" do
fill_form email: "test@test.com", password: ""
expect(page).to have_text("Password can't be blank")
end
it "informs user of an invalid credit card" do
fill_form email: "test@test.com",
password: "valid-password",
card: "bogus"
expect(page).to have_text("Card is invalid")
end
end

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

经过一段时间的研究，这是解决此问题的最干净，最常规的方法。严格来说，每个测试只应该期望/声明1件东西才能真正成为单元测试。这样可以使每个单独的测试变得更小且更易于维护。确实需要更长的时间来运行测试套件，但这是一个折衷方案。我只遇到过一种情况，我决定
expect(...)在一个测试中进行多次测试，这是因为我正在调用一个外部API，并且进行多次调用非常耗时。
