Package-Level Type Names (total 5)
/* sort by: | */
A CheckEqualError is the result CheckEqual finding an error. CheckError CheckError CheckError.Count int CheckError.In []interface{} Out1 []interface{} Out2 []interface{} (*T) Error() string *T : error
A CheckError is the result of Check finding an error. Count int In []interface{} (*T) Error() string *T : error
A Config structure contains options for running a test. MaxCount sets the maximum number of iterations. If zero, MaxCountScale is used. MaxCountScale is a non-negative scale factor applied to the default maximum. A count of zero implies the default, which is usually 100 but can be set by the -quickchecks flag. Rand specifies a source of random numbers. If nil, a default pseudo-random source will be used. Values specifies a function to generate a slice of arbitrary reflect.Values that are congruent with the arguments to the function being tested. If nil, the top-level Value function is used to generate them. func Check(f interface{}, config *Config) error func CheckEqual(f, g interface{}, config *Config) error
A Generator can generate random values of its own type. Generate returns a random instance of the type on which it is a method using the size as a size hint.
A SetupError is the result of an error in the way that check is being used, independent of the functions being tested. ( T) Error() string T : error
Package-Level Functions (total 3)
Check looks for an input to f, any function that returns bool, such that f returns false. It calls f repeatedly, with arbitrary values for each argument. If f returns false on a given input, Check returns that input as a *CheckError. For example: func TestOddMultipleOfThree(t *testing.T) { f := func(x int) bool { y := OddMultipleOfThree(x) return y%2 == 1 && y%3 == 0 } if err := quick.Check(f, nil); err != nil { t.Error(err) } }
CheckEqual looks for an input on which f and g return different results. It calls f and g repeatedly with arbitrary values for each argument. If f and g return different answers, CheckEqual returns a *CheckEqualError describing the input and the outputs.
Value returns an arbitrary value of the given type. If the type implements the Generator interface, that will be used. Note: To create arbitrary values for structs, all the fields must be exported.
