NotNaN

func NotNaN() TestDeep

NotNaN operator checks that data is a float and is not not-a-number.

got := math.NaN()
td.Cmp(t, got, td.NotNaN()) // fails
td.Cmp(t, 4.2, td.NotNaN()) // succeeds
td.Cmp(t, 4, td.NotNaN())   // fails, as 4 is not a float

CmpNotNaN shortcut

func CmpNotNaN(t TestingT, got interface{}, args ...interface{}) bool

CmpNotNaN is a shortcut for:

td.Cmp(t, got, td.NotNaN(), args...)

See above for details.

Returns true if the test is OK, false if it fails.

args… are optional and allow to name the test. This name is used in case of failure to qualify the test. If len(args) > 1 and the first item of args is a string and contains a ‘%’ rune then fmt.Fprintf is used to compose the name, else args are passed to fmt.Fprint. Do not forget it is the name of the test, not the reason of a potential failure.
