None

func None(notExpectedValues ...any) TestDeep

None operator compares data against several not expected values. During a match, none of them have to match to succeed.

td.Cmp(t, 12, td.None(8, 10, 14))     // succeeds
td.Cmp(t, 12, td.None(8, 10, 12, 14)) // fails

Note Flatten function can be used to group or reuse some values or operators and so avoid boring and inefficient copies:

prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
td.Cmp(t, 9, td.None(prime, even)) // succeeds

Example

Base example

	t := &testing.T{}

	got := 18

	ok := td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 20

	ok = td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 142

	ok = td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
	even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
	for _, got := range [...]int{9, 3, 8, 15} {
		ok = td.Cmp(t, got, td.None(prime, even, td.Gt(14)),
			"checks %v is not prime number, nor an even number and not > 14")
		fmt.Printf("%d → %t\n", got, ok)
	}

	// Output:
	// true
	// false
	// false
	// 9 → true
	// 3 → false
	// 8 → false
	// 15 → false

CmpNone shortcut

func CmpNone(t TestingT, got any, notExpectedValues []any, args ...any) bool

CmpNone is a shortcut for:

td.Cmp(t, got, td.None(notExpectedValues...), args...)

See above for details.

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

If t is a *T then its Config field is inherited.

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.

See also CmpNone godoc.

Example

Base example

	t := &testing.T{}

	got := 18

	ok := td.CmpNone(t, got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 20

	ok = td.CmpNone(t, got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 142

	ok = td.CmpNone(t, got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
	even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
	for _, got := range [...]int{9, 3, 8, 15} {
		ok = td.CmpNone(t, got, []any{prime, even, td.Gt(14)},
			"checks %v is not prime number, nor an even number and not > 14")
		fmt.Printf("%d → %t\n", got, ok)
	}

	// Output:
	// true
	// false
	// false
	// 9 → true
	// 3 → false
	// 8 → false
	// 15 → false

T.None shortcut

func (t *T) None(got any, notExpectedValues []any, args ...any) bool

None is a shortcut for:

t.Cmp(got, td.None(notExpectedValues...), args...)

See above for details.

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

See also T.None godoc.

Example

Base example

	t := td.NewT(&testing.T{})

	got := 18

	ok := t.None(got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 20

	ok = t.None(got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	got = 142

	ok = t.None(got, []any{0, 10, 20, 30, td.Between(100, 199)},
		"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
	fmt.Println(ok)

	prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
	even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
	for _, got := range [...]int{9, 3, 8, 15} {
		ok = t.None(got, []any{prime, even, td.Gt(14)},
			"checks %v is not prime number, nor an even number and not > 14")
		fmt.Printf("%d → %t\n", got, ok)
	}

	// Output:
	// true
	// false
	// false
	// 9 → true
