Documentation

Overview

Package testselection recommends bounded verification commands from static repository evidence. Recommendations neither execute tests nor prove coverage.

Functions

func NormalizeMode 

func NormalizeMode(mode string) (string, error)

NormalizeMode maps accepted spellings to a mode, or reports an error.

Types

type Command 

type Command struct {
	ID              string   `json:"id"`
	Command         []string `json:"command"`
	CWD             string   `json:"cwd"`
	Framework       string   `json:"framework"`
	TestFiles       []string `json:"test_files"`
	Affected        []string `json:"affected"`
	EvidenceReasons []Reason `json:"evidence_reasons"`
	Priority        int      `json:"priority"`
	ToolAvailable   bool     `json:"tool_available"`
	// Tier is required or optional; set by Plan, empty in raw proposals.
	Tier string `json:"tier,omitempty"`
	// GroupedFrom lists the per-file candidate IDs merged into this command.
	GroupedFrom []string `json:"grouped_from,omitempty"`
	// JUnit is the CWD-relative report file or TEST-*.xml directory the
	// runner writes, for runners whose output carries no test counts.
	JUnit string `json:"junit,omitempty"`
}

type Inventory 

type Inventory struct {
	Revision    string             `json:"revision"`
	Tests       []Test             `json:"tests"`
	Diagnostics []model.Diagnostic `json:"diagnostics"`
	Manifests   []string           `json:"manifests"`
}

func Discover 

func Discover(ctx context.Context, root, ref string) (Inventory, error)

Discover reads working-tree or immutable commit files without importing code, invoking package managers, or evaluating repository scripts/configuration.

func DiscoverProvider 

func DiscoverProvider(ctx context.Context, p indexer.Provider, revision string) (Inventory, error)

DiscoverProvider shares identical discovery logic for source-state providers.

type Omission 

type Omission struct {
	ID          string   `json:"id"`
	Command     []string `json:"command"`
	CWD         string   `json:"cwd"`
	TestFiles   []string `json:"test_files"`
	Tier        string   `json:"tier"`
	Reason      string   `json:"reason"`
	Explanation string   `json:"explanation"`
}

Omission records a candidate command that was not selected or not executed.

type Options 

type Options struct {
	Plan  *planning.Plan
	Limit int
	// ToolAvailable overrides PATH probing for deterministic tests or a known environment.
	ToolAvailable func(string) bool
}

type Proposal 

type Proposal struct {
	Omitted     []Omission   `json:"omitted,omitempty"`
	Status      model.Status `json:"status"`
	Commands    []Command    `json:"commands"`
	Inventory   Inventory    `json:"inventory"`
	Limitations []string     `json:"limitations"`
}

func Recommend 

func Recommend(ctx context.Context, root, ref string, snapshot model.Snapshot, changed []string, plan *planning.Plan) (Proposal, error)

func Select 

func Select(inv Inventory, snapshot model.Snapshot, changed []string, o Options) (Proposal, error)

Select ranks declared intent and inferred impact. All commands remain proposals: static reachability does not establish complete behavioral coverage.

type Reason 

type Reason struct {
	Code         string             `json:"code"`
	Explanation  string             `json:"explanation"`
	Evidence     model.Evidence     `json:"evidence"`
	Locations    []model.Provenance `json:"locations,omitempty"`
	RelatedFiles []string           `json:"related_files,omitempty"`
}

type Selection 

type Selection struct {
	Mode        string     `json:"mode"`
	MaxCommands int        `json:"max_commands"`
	Commands    []Command  `json:"commands"`
	Omitted     []Omission `json:"omitted"`
	Uncovered   []string   `json:"uncovered_changes"`
	Blocking    []string   `json:"blocking"`
	Candidates  int        `json:"candidate_commands"`
	TestFiles   int        `json:"selected_test_files"`
	Inventory   int        `json:"inventory_test_files"`
	Explanation string     `json:"explanation"`
}

Selection is a bounded, ordered execution plan derived from a proposal. Blocking lists reasons the selection cannot satisfy required verification; a gate must not pass on a selection with blocking reasons.

func Plan 

func Plan(p Proposal, changed []string, mode string, maxCommands int) (Selection, error)

Plan derives a bounded execution plan. It never drops a required command silently: commands beyond the budget are listed as omitted and blocking.

type Test 

type Test struct {
	ID          string           `json:"id"`
	Path        string           `json:"path"`
	Framework   string           `json:"framework"`
	PackageRoot string           `json:"package_root"`
	Evidence    model.Provenance `json:"evidence"`
	// contains filtered or unexported fields
}

Test is a conventional test file, not a compiler-validated executable case.
