When placed in the Postman 'Tests' tab, this script will unset all the variables that start with a specifically given prefix so that it's slightly different from the .clear() built-in fuction.
function cleanup() {
const clean = _.keys(pm.environment.toObject())
_.each(clean, (arrItem) => {
if (arrItem.startsWith("some_prefix")) {
pm.environment.unset(arrItem)
}
})
}
cleanup()
