  • Should Assertion Library

    Should Assertion Library,通常在测试时用到,可以与nunit 结合使用。

    已经从codeplex 迁移到 github。网址如下

    https://github.com/erichexter/Should

    github 时常访问不了,这次能访问,主要内容先摘抄记录下,备查询。

    Project Description

    The Should Assertion Library provides a set of extension methods for test assertions for AAA and BDD style tests. It provides assertions only, and as a result it is Test runner agnostic. The assertions are a direct fork of the xUnit test assertions. This project was born because test runners Should be independent of the the assertions!

    Should Assertion Library comes in two flavors, each with it's own binary.

    Standard

    Install from nuget.

    PM> install-package should
    

    The following example shows some of the assertions that are available for objects, booleans, string, and collections.

    public void Should_assertions()
    {
       object obj = null;
       obj.ShouldBeNull();
    
        obj = new object();
        obj.ShouldBeType(typeof(object));
        obj.ShouldEqual(obj);
        obj.ShouldNotBeNull();
        obj.ShouldNotBeSameAs(new object());
        obj.ShouldNotBeType(typeof(string));
        obj.ShouldNotEqual("foo");
    
        obj = "x";
        obj.ShouldNotBeInRange("y", "z");
        obj.ShouldBeInRange("a", "z");
        obj.ShouldBeSameAs("x");
    
        "This String".ShouldContain("This");
        "This String".ShouldNotBeEmpty();
        "This String".ShouldNotContain("foobar");
    
        false.ShouldBeFalse();
        true.ShouldBeTrue();
    
        var list = new List<object>();
        list.ShouldBeEmpty();
        list.ShouldNotContain(new object());
    
        var item = new object();
        list.Add(item);
        list.ShouldNotBeEmpty();
        list.ShouldContain(item);
    }
    

    Fluent

    Should.Fluent is a direct port of ShouldIt. Install from nuget.

    PM> install-package ShouldFluent
    

    The following shows the same assertions as above but in the fluent style.

    public void Should_fluent_assertions()
    {
        object obj = null;
        obj.Should().Be.Null();
    
        obj = new object();
        obj.Should().Be.OfType(typeof(object));
        obj.Should().Equal(obj);
        obj.Should().Not.Be.Null();
        obj.Should().Not.Be.SameAs(new object());
        obj.Should().Not.Be.OfType<string>();
        obj.Should().Not.Equal("foo");
    
        obj = "x";
        obj.Should().Not.Be.InRange("y", "z");
        obj.Should().Be.InRange("a", "z");
        obj.Should().Be.SameAs("x");
    
        "This String".Should().Contain("This");
        "This String".Should().Not.Be.Empty();
        "This String".Should().Not.Contain("foobar");
    
        false.Should().Be.False();
        true.Should().Be.True();
    
        var list = new List<object>();
        list.Should().Count.Zero();
        list.Should().Not.Contain.Item(new object());
    
        var item = new object();
        list.Add(item);
        list.Should().Not.Be.Empty();
        list.Should().Contain.Item(item);
    };

    Here are some additional examples of assertions using the fluent API:

    public void Should_fluent_assertions()
    {
        var numbers = new List<int> { 1, 1, 2, 3 };
        numbers.Should().Contain.Any(x => x == 1);
        numbers
            .Should().Count.AtLeast(1)
            .Should().Count.NoMoreThan(5)
            .Should().Count.Exactly(4)
            .Should().Contain.One(x => x > 2);
    
        var id = new Guid();
        id.Should().Be.Empty();
    
        id = Guid.NewGuid();
        id.Should().Not.Be.Empty();
    
        var date = DateTime.Now;
        date1.Should().Be.Today();
    
        var str = "";
        str.Should().Be.NullOrEmpty();                
    
        var one = "1";
        one.Should().Be.ConvertableTo<int>();
    
        var idString = Guid.NewGuid().ToString();
        idString.Should().Be.ConvertableTo<Guid>();
    }
