});

methods

var selectEnv = require("selectenv");

addTest(label, testfn)

add a new test. The test is exposed as a function with the same name as label on the selectEnv object, testfn should return a boolean value. The label can contain alphanumeric characters and the underscore, but must begin with a character.

protect()

write protect the current test suite. New tests can still be added, but attempting to overwrite existing tests will throw an error.

freeze()

freeze the current test suite. No new tests can be added and existing tests cannot be flushed out.

flush()

restore default state, unless frozen. used in testing.
