How Do I Correctly Set the Timeout Flag for `go test`?

Setting the Go Test Timeout Flag

Using the command go test -timeout 99999, as you've mentioned, generates an error indicating an invalid value. This is because the specified duration lacks a proper unit designation.

The -timeout flag in go test provides an aggregate time limit for all tests. To set it effectively, you must specify a valid time duration using the time.ParseDuration syntax.

For instance, if you wish to set a timeout of 300 milliseconds, use:

$ go test -timeout 300ms

Similarly, to set a timeout of 99999 seconds:

$ go test -timeout 99999s

Refer to the documentation for time.ParseDuration for further details on specifying duration strings.
