Create SpecFlow project - Continue  step4 

SpecFlow + Runner activation  step5

Bind the first step  step6

 

The purpose of this feature file is to document the expected behavior of the calculator in a way that it is both human-readable and suitable for test automation.

SpecFlow uses the Gherkin language where you can phrase the scenarios using Given/When/Then steps.

Currently there is a single scenario (automatically added by the SpecFlow project template) that describes how adding two numbers should work with the calculator.

 

Here is a closer look at the Gherkin scenario used in this template:

Scenario: Add two numbers
    Given the first number is 50
    And the second number is 70
    When the two numbers are added
    Then the result should be 120

Based on the scenario text, SpecFlow generates an automated test that executes the scenario. However, it is not yet defined what the steps of the scenario should actually “do”.

 

2- Right-click the first Given step “Given the first number is 50” and select either the “Go To Definition” or the “Go To Step Definition” command.

Visual Studio locates the step definition (binding) that belongs to this step. In this example, it opens the CalculatorStepDefinitions class and jumps to the GivenTheFirstNumberIs method.

 

*The step definition is located based on the [Binding] attribute on the class and the [Given] attribute on the method. The regular expression of the Given attribute matches the text of the scenario step.

 

3- Add the below field to the class to instantiate the calculator that we want to test and created in Step 2 of this guide (SUT).

        private readonly Calculator _calculator = new Calculator();

 

Add Living Documentation  step9

2- Install the LivingDoc CLI as a global dotnet tool.

dotnet tool install --global SpecFlow.Plus.LivingDoc.CLI

 

3- Navigate to the output directory of the SpecFlow project. In this example the solution was setup in the C:\work folder.

cd C:\work\SpecFlowCalculator\SpecFlowCalculator.Specs\bin\Debug\netcoreapp3.1

4- Run the LivingDoc CLI by using the below command to generate the HTML report.

livingdoc test-assembly SpecFlowCalculator.Specs.dll -t TestExecution.json

5- Open the generated HTML with your favorite browser. The HTML file is stored in the same folder as the output directory of the SpecFlow project.

C:\work\SpecFlowCalculator\SpecFlowCalculator.Specs\bin\Debug\netcoreapp3.1\LivingDoc.html
