FakeItEasy

DotNet.Core.Runtime.Faker

Lib to change runtime implementation by DI in integration tests

Installation

Using Moq

> dotnet add package Luna.DotNet.Core.Runtime.Faker.Moq

Using FakeItEasy

> dotnet add package Luna.DotNet.Core.Runtime.Faker.FakeItEasy

Configuration

Using FakeItEasy

• Lib DotNet.Core.Runtime.Faker.FakeItEasy
• Faker registering

var registeredValue = new DateTime();

var factory = new WebApplicationFactory<Startup>().WithWebHostBuilder(builder =>
    builder.ConfigureTestServices(services =>
    {
        services.AddServiceWithFaker<Clock>(faker => A.CallTo(() => faker.Now()).Returns(registeredValue));
    }));
var serviceProvider = factory.Services;

• Change implementation

serviceProvider.Change<Clock>(faker => A.CallTo(() => faker.Now()).Returns(new DateTime()));

• Set new value

serviceProvider.GetService<Clock>().Now();

Should returns new value =)

• Clean implementation to avoid problems in anothers tests

serviceProvider.ResetAllChanges();

Using Moq

• Lib DotNet.Core.Runtime.Faker.Moq

Very similar with FakeItEasy, but using moq syntax

factory = new WebApplicationFactory<Startup>().WithWebHostBuilder(builder =>
builder.ConfigureTestServices(services =>
{
    services.AddServiceWithFaker<Clock>(mock => mock.Setup(x => x.Now()).Returns(registeredValue));
}));

and

 serviceProvider.Change<Clock>(mock => mock.Setup(x => x.Now()).Returns(new DateTime()));

Manually

• Lib DotNet.Core.Runtime.Faker

Without any libs

factory = new WebApplicationFactory<Startup>().WithWebHostBuilder(builder =>
builder.ConfigureTestServices(services =>
{
    services.AddServiceWithFaker<Clock>(() => new FakeClock());
}));

and

serviceProvider.Change<Clock>(() => new FakeClock());
