测试方法失败（VS 中的单元测试）

发布于 2024-12-25 06:48:14 字数 1546 浏览 0 评论 0原文

我正在建立一个进行单元测试的实用实验室。下面是我正在测试的应用程序（我正在测试所有方法和构造函数）。我的所有测试都完全接受，即测试一种名为“isScalene()”的方法，该方法检查三角形是否是不等边三角形（所有边都是唯一的）。

您会在底部找到失败的测试方法。当我将“等边”更改为 True 并将“scalene”更改为 False 时，它就通过了。应用程序中出了点问题，但我就是不知道它是什么（可能在“uniqueSides() 中）。

如果有人可以帮助我，我将不胜感激！

public class Triangle {
  double[] sides;

  public Triangle(double a, double b, double c) {
      if ((a <= 0) || (b <= 0) || (c <= 0)){
          throw new ArgumentOutOfRangeException("Sidorna måste vara större än 0.");
      }
    sides = new double[] { a, b, c };
  } 

  private int uniqueSides() {
    return sides.Distinct<double>().Count();
  }

  public bool isScalene() {
      if (uniqueSides() == 1){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isEquilateral() {
      if (uniqueSides() == 3){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isIsosceles() {
      if (uniqueSides() == 2){
          return true;
      }
      else{
          return false;
      }
  }
}

...

    [TestMethod()]
    public void isScalene3Test3()
    {
        Triangle triangle = new Triangle(25, 250, 2000);

        var isosceles = triangle.isIsosceles();
        var equalateral = triangle.isEquilateral();
        var scalene = triangle.isScalene();

        Assert.IsFalse(isosceles, "Test Isosceles");
        Assert.IsFalse(equalateral, "Test Equalateral");
        Assert.IsTrue(scalene, "Test Scalene");
    }

I'm working on a laboratory practical with unit-testing. Below is the application that i'm testing (i'm testing all the methods and the constructor). All my tests are complete accept for one, that is testing a method called "isScalene()", that checks wether the triangle is a scalene (all sides are unique) or not.

You find the test method that fails at the bottom. When I change "equalateral" to True and "scalene" to False, it passes. Something is wrong in the application, but I just can't figure out what it is (probably in "uniqueSides() though).

I would be grateful if someone could help me out!

public class Triangle {
  double[] sides;

  public Triangle(double a, double b, double c) {
      if ((a <= 0) || (b <= 0) || (c <= 0)){
          throw new ArgumentOutOfRangeException("Sidorna måste vara större än 0.");
      }
    sides = new double[] { a, b, c };
  } 

  private int uniqueSides() {
    return sides.Distinct<double>().Count();
  }

  public bool isScalene() {
      if (uniqueSides() == 1){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isEquilateral() {
      if (uniqueSides() == 3){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isIsosceles() {
      if (uniqueSides() == 2){
          return true;
      }
      else{
          return false;
      }
  }
}

...

    [TestMethod()]
    public void isScalene3Test3()
    {
        Triangle triangle = new Triangle(25, 250, 2000);

        var isosceles = triangle.isIsosceles();
        var equalateral = triangle.isEquilateral();
        var scalene = triangle.isScalene();

        Assert.IsFalse(isosceles, "Test Isosceles");
        Assert.IsFalse(equalateral, "Test Equalateral");
        Assert.IsTrue(scalene, "Test Scalene");

isEquiside 应使用 1 个独特的边，isScalene 应使用 3 个。

public class Triangle {
  double[] sides;

  public Triangle(double a, double b, double c) {
      if ((a <= 0) || (b <= 0) || (c <= 0)){
          throw new ArgumentOutOfRangeException("Sidorna måste vara större än 0.");
      }
    sides = new double[] { a, b, c };
  } 

  private int uniqueSides() {
    return sides.Distinct<double>().Count();
  }

  public bool isScalene() {
      if (uniqueSides() == 3){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isEquilateral() {
      if (uniqueSides() == 1){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isIsosceles() {
      if (uniqueSides() == 2){
          return true;
      }
      else{
          return false;
      }
  }
}

isEquilateral should use 1 unique side, and isScalene should use 3.

public class Triangle {
  double[] sides;

  public Triangle(double a, double b, double c) {
      if ((a <= 0) || (b <= 0) || (c <= 0)){
          throw new ArgumentOutOfRangeException("Sidorna måste vara större än 0.");
      }
    sides = new double[] { a, b, c };
  } 

  private int uniqueSides() {
    return sides.Distinct<double>().Count();
  }

  public bool isScalene() {
      if (uniqueSides() == 3){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isEquilateral() {
      if (uniqueSides() == 1){
          return true;
      }
      else{
          return false;
      }
  }

  public bool isIsosceles() {
      if (uniqueSides() == 2){
          return true;
      }
      else{
          return false;
      }
  }
}
