In Fluent Assertions when comparing objects with DateTime properties there are sometimes a slight mismatch in the milliseconds and the comparison fail. The way we get around it is to set the comparison option like so:
actual.ShouldBeEquivalentTo(expected,
options =>
options.Using<DateTime>(ctx => ctx.Subject.Should().BeCloseTo(ctx.Expectation))
.WhenTypeIs<DateTime>());
Is there a way to set this up once and have it always apply instead of having to specify it every time we call ShouldBeEquivalentTo?
Update1: Tried the following approach but it doesn't seem to work, test fails on 1 millisecond difference. The new default does not seem to get called by the factory.
using System;
using FluentAssertions;
using FluentAssertions.Equivalency;
using Microsoft.VisualStudio.TestTools.UnitTesting;
namespace UnitTestProject1
{
class Test
{
public DateTime TestDateTime { get; set; }
}
[TestClass]
public class UnitTest1
{
[TestMethod]
public void SettingFluentAssertionDefault()
{
// arrange
var defaultAssertionOptions = EquivalencyAssertionOptions<DateTime>.Default;
EquivalencyAssertionOptions<DateTime>.Default = () =>
{
var config = defaultAssertionOptions();
config.Using<DateTime>(ctx => ctx.Subject.Should().BeCloseTo(ctx.Expectation)).WhenTypeIs<DateTime>();
return config;
};
var testDateTime = DateTime.Now;
var expected = new Test {TestDateTime = testDateTime};
// act
var actual = new Test {TestDateTime = testDateTime.AddMilliseconds(1)};
// assert
actual.ShouldBeEquivalentTo(expected);
}
}
}
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
In the real sense it has no meaning or full form. It was developed by Dennis Ritchie and Ken Thompson at AT&T bell Lab. First, they used to call it as B language then later they made some improvement into it and renamed it as C and its superscript as C++ which was invented by Dr. Stroustroupe.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
The letter c was applied by French orthographists in the 12th century to represent the sound ts in English, and this sound developed into the simpler sibilant s.
Now this can be done with the AssertionOptions static class. To use a simple example:
[TestInitialize]
public void TestInit() {
AssertionOptions.AssertEquivalencyUsing(options => options.ExcludingMissingMembers());
}
Or as in the example above:
AssertionOptions.AssertEquivalencyUsing(options =>
options.Using<DateTime>(ctx => ctx.Subject.Should().BeCloseTo(ctx.Expectation)).WhenTypeIs<DateTime>()
);
