Testing a component with different roles #1730

public ComponentTests()
{
    var authContext = this.AddTestAuthorization();
    authContext.SetAuthorized("AdminUser");
    authContext.SetRoles("Administrator");
    ...
 }

[Fact]
public async Task TestMethod()
{
    var authContext = this.AddTestAuthorization();
    authContext.SetAuthorized("AdminUser");
    authContext.SetRoles("DifferentRole");

    var component = RenderComponent<Componet>();
}

    System.InvalidOperationException : New services/implementations cannot be registered with the Services provider in a TestContext, after the first services has been retrieved from it using e.g. the GetService or GetRequiredService methods. This typically happens when a component is rendered, so make sure all services are added before that.
