Comprehensive test suite for absfs filesystem implementations.

func TestMyFS(t *testing.T) {
    suite := &fstesting.Suite{
        FS:       myFS,
        Features: fstesting.DefaultFeatures(),
    }
    suite.Run(t)
}

That's it. One struct, one method call, and you get 30+ tests covering file operations, directories, path handling, error semantics, symlinks, permissions, and timestamps.

• Baseline Tests - Standard tests that any filesystem should pass
• Feature Flags - Skip tests for unsupported capabilities (symlinks, permissions, etc.)
• Fuzz Testing - Property-based tests for edge cases and security
• Wrapper Testing - Specialized suite for filesystem wrappers (compression, encryption)
• Quick Check - Fast sanity test for development iterations
