Lax

func Lax(expectedValue interface{}) TestDeep

Lax is a smuggler operator, it temporarily enables the BeLax config flag before letting the comparison process continue its course.

It is more commonly used as CmpLax function than as an operator. It could be used when, for example, an operator is constructed once but applied to different, but compatible types as in:

bw := td.Between(20, 30)
intValue := 21
floatValue := 21.89
td.Cmp(t, intValue, bw)           // no need to be lax here: same int types
td.Cmp(t, floatValue, td.Lax(bw)) // be lax please, as float64 ≠ int

Note that in the latter case, CmpLax() could be used as well:

td.CmpLax(t, floatValue, bw)

TypeBehind method returns the greatest convertible or more common reflect.Type of expectedValue if it is a base type (bool, int*, uint*, float*, complex*, string), the reflect.Type of expectedValue otherwise, except if expectedValue is a TestDeep operator. In this case, it delegates TypeBehind() to the operator.

Example

Base example

CmpLax shortcut

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

CmpLax is a shortcut for:

td.Cmp(t, got, td.Lax(expectedValue), 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.

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