c# - C#单元测试。并非所有路径都返回值

Question

我正在编写一组简单的单元测试。在此特定测试中，我正在测试该函数的所有标准文本输入。

但是，当我尝试编译时，会收到此错误


  ConverterTests.ConvertSixteenthsFractionalToDecimal_AverageCase（）'：并非所有代码路径都返回值


我应该更改什么来解决此编译错误？

这是代码：

        [TestMethod]
        public double ConvertSixteenthsFractionalToDecimal_AverageCase()
        {
            // arrange
            string input = "1/16";
            int expected = 1;
            // act
            int actual = clsDimension.CvtSixteenthsFractionalToDecimal(input);
            // assert
            Assert.AreEqual(expected, actual);

            // arrange
            input = "1/8";
            expected = 2;
            // act
            actual = clsDimension.CvtSixteenthsFractionalToDecimal(input);
            // assert

Answer 1

public double ConvertSixteenthsFractionalToDecimal_AverageCase

应该

public void ConvertSixteenthsFractionalToDecimal_AverageCase

测试方法不返回值。

作为旁白：

这不是您编写好的测试的方式，每个安排，操作，断言都应该是它自己的测试用例，否则一个测试失败将阻止其他所有测试运行。
