What it does

Horse Integration Tests is an agent skill from HashLoad/horse. Guide for writing automated integration tests for Horse endpoints using DUnit/DUnitX and THTTPClient.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Integration testing. The repository describes itself as: Fast, opinionated, minimalist web framework for Delphi. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit d4351a5. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are pascal).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Horse Integration Tests loads about 964 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 193 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~31
When it runs · the whole SKILL.md, loaded when a task matches: ~964

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Horse Integration Testing

Automated integration tests ensure your API routes, request parsing, and error-handling pipelines behave correctly under simulated HTTP traffic.

1. The Dynamic Port Pattern

When running tests locally or in CI/CD pipelines (like GitHub Actions), static ports (e.g., 9000) might be occupied. To avoid port conflicts:

Generate a dynamic port for each test run.
Start Horse on that port inside the setup method.
Perform HTTP requests against http://localhost:<dynamic_port>.
Terminate Horse inside the teardown method.

2. Integration Test Example (DUnitX)

Here is a complete integration test suite demonstrating how to bootstrap Horse, perform requests with Delphi's native THTTPClient, and assert responses:

pascal

unit Test.UserAPI;

interface

uses
  DUnitX.TestFramework,
  System.Net.HttpClient,
  System.SysUtils;

type
  [TestFixture]
  TTestUserAPI = class
  private
    FPort: Integer;
    FClient: THTTPClient;
    function GetBaseURL: string;
  public
    [SetupFixture]
    procedure SetupFixture; // Start Horse Server
    [TearDownFixture]
    procedure TearDownFixture; // Terminate Horse Server
    [Setup]
    procedure Setup;
    [TearDown]
    procedure TearDown;
    
    [Test]
    procedure TestGetPingReturnsPong;
    [Test]
    procedure TestGetInvalidUserReturns404;
  end;

implementation

uses
  Horse,
  System.JSON,
  System.Net.URLClient;

function TTestUserAPI.GetBaseURL: string;
begin
  Result := 'http://localhost:' + FPort.ToString;
end;

procedure TTestUserAPI.SetupFixture;
begin
  // Choose a random dynamic port
  Randomize;
  FPort := 10000 + Random(50000);
  
  // Register endpoints to test
  THorse.Get('/ping',
    procedure(Req: THorseRequest; Res: THorseResponse; Next: TProc)
    begin
      Res.Send('pong');
    end);

  THorse.Get('/users/:id',
    procedure(Req: THorseRequest; Res: THorseResponse; Next: TProc)
    var
      LId: Integer;
    begin
      LId := Req.Params.Field('id').AsInteger;
      if LId = 999 then
        Res.Status(THTTPStatus.NotFound).Send('User not found')
      else
        Res.Send('User found');
    end);

  // Start Horse asynchronously (non-blocking)
  THorse.Listen(FPort);
end;

procedure TTestUserAPI.TearDownFixture;
begin
  // Terminate the process / stop Horse provider
  THorse.Terminate;
end;

procedure TTestUserAPI.Setup;
begin
  FClient := THTTPClient.Create;
end;

procedure TTestUserAPI.TearDown;
begin
  FClient.Free;
end;

procedure TTestUserAPI.TestGetPingReturnsPong;
var
  LResponse: IHTTPResponse;
begin
  LResponse := FClient.Get(GetBaseURL + '/ping');
  
  Assert.AreEqual(200, LResponse.StatusCode);
  Assert.AreEqual('pong', LResponse.ContentAsString);
end;

procedure TTestUserAPI.TestGetInvalidUserReturns404;
var
  LResponse: IHTTPResponse;
begin
  LResponse := FClient.Get(GetBaseURL + '/users/999');
  
  Assert.AreEqual(404, LResponse.StatusCode);
  Assert.AreEqual('User not found', LResponse.ContentAsString);
end;

initialization
  TDUnitX.RegisterTestFixture(TTestUserAPI);
end.

3. Best Practices for Integration Testing

Isolate Database State: Before running tests, mock database tables or use transactional rollbacks to ensure tests start with clean, predictable data.
Separate Test Logic: Keep your route handlers in dedicated Controller units. Do not define routes inline in your test project setup unless you are testing general configuration middleware behavior.
Always call THorse.Terminate: Failing to call Terminate in your tear down fixture will leave the TCP socket open, preventing subsequent test executions from binding to the same port.
