Custom Tests with C#Bot

By default, C#Bot writes tests for the client-side, server-side and test target.

• Client-side: These tests reside in the clientside in form of *.tsx files. React uses Jest by default.
• Server-side: These tests reside in the testtarget/serverside directory. C# uses XUnit bundled with its test framework for unit and integration tests.
• End user: These tests reside in the testtarget/selenium directory. Unlike the server-side tests, these tests focus on end-to-end or user acceptance testing with Selenium, XUnit and SpecFlow 3.
• API: These tests reside in the testtarget/api directory. These tests focus on testing API endpoints using Restsharp and XUnit.

We will be making a simple Test Target Specflow test. The test will be a custom invalid login test that uses a mixture of C# bot-written steps and a custom step.

Setting Up The Solution

Navigate to your root project directory and run the following commands to setup the solution:

dotnet new sln
dotnet sln add ./testtarget/TestDataLib/TestDataLib.csproj
dotnet sln add ./testtarget/Selenium/SeleniumTests.csproj
dotnet sln add ./testtarget/API/APITests.csproj
dotnet sln add ./testtarget/Serverside/ServersideTests.csproj
dotnet sln add ./serverside/src/[PROJECTNAME].csproj

You should now be able to open the solution in your IDE.

Feature Files

The first step is to setup a Specflow Feature file. To do this, create a file in the /testtarget/Selenium/Tests/Manual/ folder called CustomFishnaticsLoginTests.feature. Open this file in your editor of choice, and paste in the following:

Feature: CustomFishnaticsLoginTests

Custom login tests

@new
Scenario: I attempt to login to fishnatics with invalid credentials
    Given I login to the site with username notreal@example.com  and password notreal then I expect login failure
    Then I want to print a simple message "notreal@example.com cannot be logged in" to the test output

The first Given step is already defined as a bot-written step in the Fishnatics project. The second Then step is undefined and will need to be defined.

Step Definition

Navigate to the /testtarget/Selenium/Steps/Manual/ folder and create new file called CustomFishnaticsLoginSteps.cs. Open the file and paste in the following code.

using SeleniumTests.Setup;
using TechTalk.SpecFlow;

namespace SeleniumTests.Steps.Manual
{
    [Binding]
    public class CustomFishnaticsLoginSteps
    {
        private readonly ContextConfiguration _context;

        public CustomFishnaticsLoginSteps(ContextConfiguration contextConfiguration)
        {
            _context = contextConfiguration;
        }
    }
}

The contextConfiguration gives access to all the important tools for building integrations tests (e.g. webDriver, testOutputHelper). We will use it in our step to print a simple message to the test output.

Add the following step definition to the CustomFishnaticsLoginSteps class.

[Then(@"I want to print a simple message ""([^""]*)"" to the test output")]
    public void ThenIWantToPrintASimpleMessageToTheTestOutput(string message)
    {
        _context.TestOutputHelper.WriteLine(message);
    }

Running Tests

Tests can be run through the command line, or through an IDE. Before running any Specflow tests, ensure that both server and client are running.

Command Line

Navigate to /testtarget/selenium/ and run the command:

dotnet test --filter Category=new

We use the @new tag added in the .feature file to run specific tests or groups of tests, by using the --filter Category=[tag].

Visual Studio

In order to run the tests through Visual Studio, the Specflow package needs to be installed. Follow the steps in this guide from Specflow to install Specflow for Visual Studio.

Open up the test explorer by going to Test -> Test Explorer in the Visual Studio navigation bar. Now find the CustomFishnaticsLoginTestsFeature in the test explorer, right click on it, and select Run.
