测试冗长的表格，而无需每次都重写所有的 fill_ins

Question

我有一个很长的表格，对于其中的 3 个字段，我需要分别测试它们是否填写正确或错误，因为错误会导致非常不同的操作。但是编写这样的集成测试非常乏味且不干：

# Test 1

describe "test where field3 fails" do

  before do
    fill_in "field1", with: "passing info"
    fill_in "field2", with: "passing info"
    fill_in "field3", with: "not passing info"
    ...
  end

  it "should lead to an error specific to field3" do
    ...
  end

end

# Test 2

describe "test where field2 fails" do

  before do
    fill_in "field1", with: "passing info"
    fill_in "field2", with: "not passing info"
    fill_in "field3", with: "passing info"
    ...
  end

  it "should lead to an error specific to field2" do
    ...
  end

end

# Test 3

describe "test where field1 fails" do

  before do
    fill_in "field1", with: "not passing info"
    fill_in "field2", with: "passing info"
    fill_in "field3", with: "passing info"
    ...
  end

  it "should lead to an error specific to field1" do
    ...
  end

end

Answer 1

在这种情况下，我建议编写如下所示的数据驱动测试

     describe "test all form fields" do |data|

  before do
    fill_in "field1", with: data[0]
    fill_in "field2", with: data[1]
    fill_in "field3", with: data[2]
    ...
  end   

  it "should lead to an error message" do |CorrespondingErrorMsg|
    ...
  end  

这样所有的组合都将在测试数据中定义，而不是在代码中，如果没有的话，以后会这样。验证甚至增加或减少您不必触摸代码。只有数据。 我希望让溶液变干是有意义的。
