Send command line arguments to specflow tests

Question

I have a feature files as part of specflow project. The environment in which i need to execute the specflow tests is taken from the parameter mentioned in "appsettings.json".

I want to run a specflow test from command line wherein I would like to have an option to override the parameters in appsettings.json from the command line arguments.

Can this be achieved?

In Hooks.cs file, i am reading the arguments value in BEFORESCENARIO binding.

[BeforeScenario]
public void readarguments()
{
    string[] args = Environment.GetCommandLineArguments();
}

I am not able to get env=QA as a string in the array args

I ran the test using below command from command prompt :

dotnet test --filter "TestName1" -- "env=QA"

Answer 1

Command line to be used in git bash--

dotnet test -- TestRunParameters.Parameter\(name="\""Country"\"", value="\""INDIA"\""\)

.runsettings file content --

<?xml version="1.0" encoding="utf-8" ?>
<RunSettings>
    <TestRunParameters>
        <Parameter name="COUNTRY" value="INDIA" />      
    </TestRunParameters>
</RunSettings>

Process to access the parameter value in a test --

String _country = TestContext.Parameters["COUNTRY"];
