Testing a component with different roles

[bLinMil]

I was browsing the documentation and came across this:

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

which works when I put it in my testContext constructor along with all my other services.

However, the component should show something different based on the roles. If I try adding this to my [Fact]

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

    var component = RenderComponent<Componet>();
}

I get this error

    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.

How can I set different roles dynamically in my test suite in order to test different functionalities? Thank you

You could move this out into a separate method (away from the ctor): SetAdmin and SetDifferntRole and call them explicitly in your test functions.

Ah yea that seemed to work. The issue was calling this.AddTestAuthorization() inside the test method. I made a private member and initialized it in the constructor. Then used a method to dynamically set the role by a string.

Thank you
