All

func All(expectedValues ...any) TestDeep

All operator compares data against several expected values. During a match, all of them have to match to succeed. Consider it as a “AND” logical operator.

td.Cmp(t, "foobar", td.All(
  td.Len(6),
  td.HasPrefix("fo"),
  td.HasSuffix("ar"),
)) // succeeds

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

stringOps := td.Flatten([]td.TestDeep{td.HasPrefix("fo"), td.HasSuffix("ar")})
td.Cmp(t, "foobar", td.All(
  td.Len(6),
  stringOps,
)) // succeeds

One can do the same with All operator itself:

stringOps := td.All(td.HasPrefix("fo"), td.HasSuffix("ar"))
td.Cmp(t, "foobar", td.All(
  td.Len(6),
  stringOps,
)) // succeeds

but if an error occurs in the nested All, the report is a bit more complex to read due to the nested level. Flatten does not create a new level, its slice is just flattened in the All parameters.

TypeBehind method can return a non-nil reflect.Type if all items known non-interface types are equal, or if only interface types are found (mostly issued from Isa) and they are equal.

Example

Base example

	t := &testing.T{}

	got := "foo/bar"

	// Checks got string against:
	//   "o/b" regexp *AND* "bar" suffix *AND* exact "foo/bar" string
	ok := td.Cmp(t,
		got,
		td.All(td.Re("o/b"), td.HasSuffix("bar"), "foo/bar"),
		"checks value %s", got)
	fmt.Println(ok)

	// Checks got string against:
	//   "o/b" regexp *AND* "bar" suffix *AND* exact "fooX/Ybar" string
	ok = td.Cmp(t,
		got,
		td.All(td.Re("o/b"), td.HasSuffix("bar"), "fooX/Ybar"),
		"checks value %s", got)
	fmt.Println(ok)

	// When some operators or values have to be reused and mixed between
	// several calls, Flatten can be used to avoid boring and
	// inefficient []any copies:
	regOps := td.Flatten([]td.TestDeep{td.Re("o/b"), td.Re(`^fo`), td.Re(`ar$`)})
	ok = td.Cmp(t,
		got,
		td.All(td.HasPrefix("foo"), regOps, td.HasSuffix("bar")),
		"checks all operators against value %s", got)
	fmt.Println(ok)

	// Output:
	// true
	// false
	// true

CmpAll shortcut

func CmpAll(t TestingT, got any, expectedValues []any, args ...any) bool

CmpAll is a shortcut for:

td.Cmp(t, got, td.All(expectedValues...), 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.

T.All shortcut

func (t *T) All(got any, expectedValues []any, args ...any) bool

All is a shortcut for:

t.Cmp(got, td.All(expectedValues...), args...)

See above for details.

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