xUnit之Equal(2)

继续上节，列举一下Equal测试的类型：

1. ArrayTest

[Fact]
public void Array()
{
    string[] expected = { "@", "a", "ab", "b" };
    string[] actual = { "@", "a", "ab", "b" };

    Assert.Equal(expected, actual);
    Assert.Throws<NotEqualException>(() => Assert.NotEqual(expected, actual));

    Assert.Equal("a", "b");
}

2. Null

[Fact]
public void EqualsNull()
{
    Assert.Equal<object>(null, null);
}

3. Numeric Test

[Fact]
public void DecimalEqualsFails()
{
    decimal expected = 25;
    decimal actual = 42;

    Assert.Throws<EqualException>(() => Assert.Equal(expected, actual));
}

[Fact]
public void EqualsSByte()
{
    const sbyte valueType = 35;
    const sbyte referenceValue = 35;

    Assert.True(valueType == referenceValue);
    Assert.Equal(referenceValue, valueType);
    Assert.Equal<sbyte>(valueType, 35);
    Assert.Equal<sbyte>(referenceValue, 35);
}

4.Using a comparer

[Fact]
public void EqualsStringIgnoreCase()
{
    string expected = "TestString";
    string actual = "testString";

    Assert.False(actual == expected);
    Assert.NotEqual(expected, actual);
    Assert.Equal(expected, actual, StringComparer.CurrentCultureIgnoreCase);
}

5.Null? Test

[Fact]
public void NullableValueTypesCanBeNull()
{
    DateTime? dt1 = null;
    DateTime? dt2 = null;

    Assert.Equal(dt1, dt2);
}

6.Precision Test

[Fact]
public void AssertEqualWithDecimalWithPrecision()
{
    Assert.Equal(0.11111M, 0.11444M, 2);
}
