A '''go/no-go''' test is a two-step verification process that uses two boundary conditions, or a [[binary classification]]. The test is passed only when the ''go'' condition has been met and also the ''no-go'' condition has failed.

The test gives no information as to the degree of conformance to, or deviation from the boundary conditions. These tests can be used for [[statistical process control]] purposes. There are specific SPC tools that use parameter based measurements (e.g., P-charts) for determining the stability of a process.

It has uses in engineering, psychology, military, and manufacturing. For example, a rocket [[launch status check]] involves a go/no-go test.

=== Psychology ===

In [[psychology]], go/no-go test, developed by [[neuropsychologist]] [[Alexander Luria]] in 1940-50s is used to measure a participant's capacity for switching between several types of behavioural response ("plasticity") and control of adequacy of response (impulse control and sustained attention). Since the work of [[Alexander Luria]] in [[neuropsychology]], such response is linked to the cortical [[frontal lobes]].

For example, a go/no-go test that requires a participant to perform an action given certain stimuli (e.g., press a button) and also inhibit that action under a different set of stimuli (e.g., not press that same button).
