javascript - JS 单元测试使用不同参数运行多次

Question

他们是否有办法在一个测试中拥有多个参数，而不是再次复制和粘贴函数？

C# 的 NUnit 示例:

[TestCase("0", 1)]
[TestCase("1", 1)]
[TestCase("2", 1)]
public void UnitTestName(string input, int expected)
{
    //Arrange

    //Act

    //Assert
}

我想要的 Js 内容:

describe("<Foo />", () => {

    [TestCase("false")]
    [TestCase("true")]
    it("option: enableRemoveControls renders remove controls", (enableRemoveControls) =>  {
        mockFoo.enableRemoveControls = enableRemoveControls;

        //Assert that the option has rendered or not rendered the html
    });
});

Answer 1

另一种方法是使用 Jest 。它有这个functionality内置:

test.each`
  a    | b    | expected
  ${1} | ${1} | ${2}
  ${1} | ${2} | ${3}
  ${2} | ${1} | ${3}
`('returns $expected when $a is added $b', ({a, b, expected}) => {
  expect(a + b).toBe(expected);
});
