Question

I need a local HTTP server for my unit test.

When I try to activate TIdHTTPServer at SetUp, it fails with EThread message:

“Thread Error: descriptor not valid (6)”

This is how I initialize it:

type
  TestMyUnit = class(TTestCase)
...
procedure TestMyUnit.SetUp;
begin
  FServer := TIdHTTPServer.Create(nil);
  FServer.OnCommandGet := HTTPServerCommandGet;
  FServer.Active := True;   // <---- This will cause error
end;

Maybe there are some restrictions using Indy’s TIdHTTPServer with DUnit framework?

• Delphi 2010
• Indy 10

Exception was thrown somewhere after this line in TIdListenerThread.Run proc (IdCustomTCPServer unit)

LIOHandler := Server.IOHandler.Accept(Binding, Self, LYarn);

However, I can’t trace it deeper, I don’t know why.

Solved. I have my own DPK with self-designed components (used by this unit-test), and there was 1 unit with references to Indy. After I have rebuild that package, the compiler proposed me to add some new DCCReference to Indy components. After I reinstalled my package, that error in unit-test has gone.

I can’t imagine the cause-and-effect relations, but now it’s ok.
