Create and running tests- part 4

I have made a TestWebSite,in .NET Core 3.1,I was also thinking that WebApplicationFactory exists and tutorial like https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-3.1   it will be easy to test the site.

However,I have found the hard way that is not a real server : it does not have the adresses / ports open. Read https://github.com/dotnet/aspnetcore/issues/4892 .

So I have made a hack – see public class LocalServerFactory in the source code.

Also,WithWebHostBuilder helps create a new WebApplicationFactory  -used to test with / or without /  CLI_ENABLED command line

Second point was testing methods like

configuration.GetValue<int?>(“CLI_HELP”,null);

Because it is an extension function,I cannot mock. So I refactored the code to

public bool ShouldShowHelp()
{
//deleted for easy of automating testing
//var showHelp = configuration.GetValue<int?>(“CLI_HELP”,null);
var cliHelp = configuration[“CLI_HELP”];
var showHelp = int.TryParse(cliHelp,out var val) && val == 1;
return showHelp;
}

Also,I have resorted to XBehave,to have tests written in easy form. And to Moq to mock various properties.
