**Run `go test ./...` from the repository root to execute all unit tests in the majd/ipatool repository, which recursively discovers and runs every `*_test.go` file across the `cmd` and `pkg` directories.**

IPATool is a Go-based command-line utility that interacts with Apple’s App Store API. Understanding how to run IPATool unit tests is essential for contributors validating pull requests or developers verifying local modifications. The project uses the standard Go testing framework and organizes tests across core logic, utilities, and command-line interfaces.

## Prerequisites for Running IPATool Tests

Before executing the suite, ensure your environment meets these requirements:

- **Go 1.22 or newer.** The `go.mod` file in the repository root declares this minimum version. Verify your installation with `go version`.
- **Local repository clone.** Obtain the source code from majd/ipatool:

  ```bash
  git clone https://github.com/majd/ipatool.git
  cd ipatool
  ```

- **Resolved dependencies.** Download required modules before testing:

  ```bash
  go mod tidy
  ```

## Running the Complete Test Suite

Execute the following command from the repository root to run all tests:

```bash
go test ./...

```

This command recursively compiles each package and executes every file matching the `*_test.go` pattern found in subdirectories. The suite validates components in `pkg/appstore`, `pkg/util`, and `cmd` without requiring external Apple API credentials, as the test harness uses stubbed responses for local runs.

## Understanding the Test Architecture

The test suite is organized into three logical layers that mirror the source code structure.

### Core Logic Tests in `pkg/appstore`

These tests validate the App Store client implementation, request signing, and response handling. Key files include [`appstore_login_test.go`](https://github.com/majd/ipatool/blob/main/appstore_login_test.go) and [`appstore_download_test.go`](https://github.com/majd/ipatool/blob/main/appstore_download_test.go), which exercise authentication flows and download mechanisms against mocked endpoints.

### Utility Tests in `pkg/util`

Helper functions for ZIP extraction and platform detection reside here. The test files [`zip_test.go`](https://github.com/majd/ipatool/blob/main/zip_test.go) and [`util_test.go`](https://github.com/majd/ipatool/blob/main/util_test.go) verify that auxiliary operations handle edge cases correctly across supported platforms.

### Command Tests in `cmd`

The Cobra command wrappers for operations like `list-versions`, `download`, and `purchase` are tested in [`cmd_test.go`](https://github.com/majd/ipatool/blob/main/cmd_test.go) and [`purchases_test.go`](https://github.com/majd/ipatool/blob/main/purchases_test.go). These ensure command-line flags parse correctly and invocations route to the underlying library with proper parameters.

## Advanced Testing Options

Target specific testing scenarios using these standard Go tool flags:

- **Verbose output.** Add `-v` to see individual test names and detailed logs:

  ```bash
  go test -v ./...
  ```

- **Single package focus.** Narrow execution to a specific package path:

  ```bash
  go test ./pkg/appstore
  ```

- **Race detection.** Identify concurrency issues with the race detector:

  ```bash
  go test -race ./...
  ```

- **Coverage analysis.** Generate and view HTML coverage reports:

  ```bash
  go test -coverprofile=coverage.out ./...
  go tool cover -html=coverage.out -o coverage.html
  ```

## Platform-Specific Considerations

Tests that rely on macOS-only APIs—such as Keychain access—are guarded with Go build tags. When running IPATool unit tests on Linux or Windows, these platform-specific tests are automatically skipped, ensuring the suite passes cleanly without manual configuration changes.

## CI and GitHub Actions Workflow

The Continuous Integration configuration in [`.github/workflows/unit-tests.yml`](https://github.com/majd/ipatool/blob/main/.github/workflows/unit-tests.yml) executes `go test ./...` on every push to the repository. This workflow validates changes across multiple platforms, ensuring that code remains test-covered regardless of the local development environment.

## Summary

- Execute the full suite with `go test ./...` from the repository root.
- **Go 1.22+** is required to compile and run the test binaries.
- Unit tests are organized in `pkg/appstore`, `pkg/util`, and `cmd` directories.
- macOS-specific tests use build tags and skip automatically on other platforms.
- Generate coverage reports using `go test -coverprofile` followed by `go tool cover`.

## Frequently Asked Questions

### What Go version is required to run IPATool unit tests?

The majd/ipatool repository requires **Go 1.22 or newer**, as specified in the `go.mod` file. Verify your version with `go version` before executing the test suite.

### How do I run only specific test packages?

Specify the package path after the `go test` command to narrow the scope. For example, `go test ./pkg/appstore` runs only the App Store client tests, while `go test ./cmd` executes the Cobra command tests.

### Will IPATool tests fail on Linux or Windows?

No. Tests requiring macOS-specific APIs—such as those involving Keychain access—are guarded with build constraints and automatically skip on non-macOS platforms. The suite is designed to pass on Linux, Windows, and macOS.

### How can I generate a test coverage report for IPATool?

Run `go test -coverprofile=coverage.out ./...` to generate a coverage profile, then use `go tool cover -html=coverage.out -o coverage.html` to create a browsable HTML report that highlights covered and uncovered code paths.
