func Dump ¶

func Dump(ctx context.Context, w io.Writer) (n int, err error)

Dump is a convenience function to dump the current contents of the memory logger to the writer.

This will panic if the current logger is not a memory logger.

func MustDumpStdout ¶

func MustDumpStdout(ctx context.Context)

MustDumpStdout is a convenience function to dump the current contents of the memory logger to stdout.

This will panic if the current logger is not a memory logger.

func Reset ¶

func Reset(ctx context.Context)

Reset is a convenience function to reset the current memory logger.

This will panic if the current logger is not a memory logger.

func ShouldHaveLog ¶

func ShouldHaveLog(actual any, expected ...any) string

ShouldHaveLog is a goconvey custom assertion which asserts that the logger has received a log. It takes up to 3 arguments.

`actual` should either be a *MemLogger or a context.Context containing a *MemLogger.

argument 1 (expected[0]) is the log level. argument 2 (expected[1]) is a substring the message. If omitted or the empty string, this value is not checked. argument 3 (expected[2]) is the fields data. If omitted or nil, this value is not checked.

func ShouldNotHaveLog ¶

func ShouldNotHaveLog(actual any, expected ...any) string

ShouldNotHaveLog is the inverse of ShouldHaveLog. It asserts that the logger has not seen such a log.

func Use ¶

func Use(ctx context.Context) context.Context

Use adds a memory backed Logger to Context, with concrete type *MemLogger. Casting to the concrete type can be used to inspect the log output after running a test case, for example.
