RecordVisitors–code coverage–part 3

Now I have to do some code coverage . The easy way is to test the web application – doing an integration test. Use this as a starting point: https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-5.0

I have 2 kind of tests: HappyPath  -when all is working ok – and  TestErrors  – when it is not.

The code for all working ok is

public async void TestFakeUser()
{
    // Arrange
    var client = _factory.CreateClient();

    // Act
    var response = await client.GetStringAsync("/recordVisitors/AllVisitors5Min");

    // Assert
    var str = "Jean Irvine";
    Assert.True(response.Contains(str),$"{response} must contain {str}");
                
}

and for testing errors

[Fact]
public  void TestFakeUser()
{
    _factory.RemoveServices = true;
    _factory.RemoveFakeUser = false;
    var ex = Record.Exception(()=>_factory.CreateClient());

    Assert.IsType<ArgumentException>(ex);
            
}
[Fact]
public async void TestNoUser()
{
    _factory.RemoveServices = false;

    _factory.RemoveFakeUser= true;
    // Arrange
    var client = _factory.CreateClient();

    // Act
    var response = await client.GetStringAsync("/recordVisitors/AllVisitors5Min");

    // Assert
    var str = "Jean Irvine";
    Assert.True(response.Contains(str),$"{response} must contain {str}");

}

The code coverage has reached 94% after 3 iterations – it is ok. You can see the results at https://app.codecov.io/gh/ignatandrei/RecordVisitors
