How Do I Correctly Set the Go Test Timeout Flag?

Setting Go Test Timeout Flag: Parsing Duration Correctly

Q: When setting the timeout flag for "go test" with a duration value (e.g., "-timeout 99999"), an error is encountered.

A: To resolve this error, use a valid input for time.ParseDuration. Instead of using "99999", try specifying the duration in a unit format accepted by time.ParseDuration. For example:

• "-timeout 300ms"
• "-timeout 99999s"

The "go test" command-line tool provides a "-timeout" flag that allows you to set a time limit for tests. As per the official documentation, duration flags accept any input valid for time.ParseDuration. This function expects a time duration string in a specific format, which includes a numerical value followed by a unit suffix (such as milliseconds, seconds, minutes, or hours).

By providing the duration in a valid format, you ensure that the "go test" tool can correctly interpret and enforce the timeout limit. Failure to use a valid format will result in an error, as the tool cannot parse the duration string appropriately.
