Overview ¶

Package logtest provides a minimal, stdlib-only slog capture handler for asserting on log output in tests. It exists so the transit test suite can verify middleware logging without depending on go-tool-base's pkg/logger.

Functions ¶

func NewNoop ¶

func NewNoop() *slog.Logger

NewNoop returns a *slog.Logger that discards all output. Use it where a test needs a logger but does not assert on captured records.

Types ¶

type Buffer ¶

type Buffer struct {
	*slog.Logger
	// contains filtered or unexported fields
}

Buffer captures log records in memory. It embeds a *slog.Logger backed by a capturing handler, so callers pass buf.Logger wherever a *slog.Logger is expected and then assert on Entries().

func New ¶

func New() *Buffer

New returns a Buffer that captures every record at any level. Loggers derived from it via With/WithGroup capture into the same buffer.

func (*Buffer) Contains ¶

func (b *Buffer) Contains(substr string) bool

Contains reports whether any captured record's message contains substr.

func (*Buffer) Entries ¶

func (b *Buffer) Entries() []Entry

Entries returns all captured records, in order.

func (*Buffer) Len ¶

func (b *Buffer) Len() int

Len returns the number of captured records.

type Entry ¶

type Entry struct {
	Level   slog.Level
	Message string
	Keyvals []any
}

Entry is a single captured log record, flattened for assertion. Keyvals holds the record's attributes (including those accumulated via With) as alternating key/value pairs.
