18,664 PointsChallenge Task 4 of 4, Implement the Subtract method so that the test passes. Not passing.
Code not passing, some silly mistake cannot find.
public class Calculator
{
public double Result;
public Calculator(double number)
{
Result = number;
}
public void Add(double number)
{
Result += number;
}
public void Substract(double number)
{
Result -= number;
}
}
using Xunit;
public class CalculatorTests
{
[Fact]
public void Initialization()
{
var expected = 1.1;
var target = new Calculator(1.1);
Assert.Equal(expected, target.Result, 1);
}
[Fact]
public void BasicAdd()
{
var target = new Calculator(1.1);
target.Add(2.2);
var expected = 3.3;
Assert.Equal(expected, target.Result, 1);
}
[Fact]
public void BasicSubtract()
{
var target = new Calculator(1.1);
target.Substract(0.2);
var expected = 0.9;
Assert.Equal((); target.Result >= 0.9);
}
}

16,646 PointsThere is a typo in the name of the Subtract method. Other than that, the test should look like this:
[Fact]
public void BasicSubtract()
{
var target = new Calculator(1.1);
target.Subtract(0.2);
var expected = 0.9;
Assert.Equal(expected, target.Result, 1);
}
