WebNativeDEV.SINUS.Core 1.0.5

SINUS (Selenium In .Net Ui Solutions)

Main idea of this package is to provide a readable and easy way to perform web UI tests. Hereby the package is opinionated and makes some decisions that need to be accepted for its usage. It defines a way (one of hundreds) how tests should be written and defines also the technology to use. Additionally a lot of checks are added to guarantee consistency and preventing memory leaks.

Dependencies:

• MS Test
• Microsoft.AspNetCore.Mvc.Testing
• Microsoft.Extensions.Logging...
• FluentAssertions
• NSubstitute
• Selenium

There are hard dependencies in SINUS to C#, newest .NET-Versions, MS-Test and Selenium (including partly Chrome) using BaseClasses and pre-defined patterns. SINUS focuses on a Given-When-Then approach of writing tests (BDT - Behaviour Driven Testing) to provide human readable descriptions with few effort.

Example:

    [TestMethod]
    public void Given_ATestSystem_When_StoringTheTitle_Then_ItShouldBeTheRightValue()
        => this.Test(r => r
            .GivenASystemAndABrowserAtRandomEndpoint<Program>("SimpleView", "/simpleView")
            .When((browser, data) => data.StoreActual(browser.Title))
            .Then((browser, data) => data.Should().ActualBe("SINUS TestSystem"))
            .DebugPrint());

Calling the test:

dotnet test --filter "FullyQualifiedName=WebNativeDEV.SINUS.Tests.SimpleBrowserTests.Given_ATestSystem_When_StoringTheTitle_Then_ItShouldBeTheRightValue"

Debug standard output:

The test result is evaluated as successful for test 'Given_ATestSystem_When_StoringTheTitle_Then_ItShouldBeTheRightValue'. (Checked Exceptions: 0, TaskId: 1, ThreadId: 4)

By reducing the complexity you are not able to use all of the features Selenium has. Nevertheless, the most common features are supported and covered by SINUS in a nicely shaped API that guides you through the test case and will add logging so that errors can be found simpler without any effort on the test-developer side.
