HasSuffix
func HasSuffix(expected string) TestDeep
HasSuffix operator allows to compare the suffix of a string (or
convertible), []byte (or convertible), error or fmt.Stringer
interface (error interface is tested before fmt.Stringer).
td.Cmp(t, []byte("foobar"), td.HasSuffix("bar")) // succeeds
type Foobar string
td.Cmp(t, Foobar("foobar"), td.HasSuffix("bar")) // succeeds
err := errors.New("error!")
td.Cmp(t, err, td.HasSuffix("!")) // succeeds
bstr := bytes.NewBufferString("fmt.Stringer!")
td.Cmp(t, bstr, td.HasSuffix("!")) // succeeds

Examples
Base example
t := &testing.T{}
got := "foobar"
ok := td.Cmp(t, got, td.HasSuffix("bar"), "checks %s", got)
fmt.Println("using string:", ok)
ok = td.Cmp(t, []byte(got), td.HasSuffix("bar"), "checks %s", got)
fmt.Println("using []byte:", ok)
// Output:
// using string: true
// using []byte: true
Stringer example
t := &testing.T{}
// bytes.Buffer implements fmt.Stringer
got := bytes.NewBufferString("foobar")
ok := td.Cmp(t, got, td.HasSuffix("bar"), "checks %s", got)
fmt.Println(ok)
// Output:
// true
Error example
t := &testing.T{}
got := errors.New("foobar")
ok := td.Cmp(t, got, td.HasSuffix("bar"), "checks %s", got)
fmt.Println(ok)
// Output:
// true
CmpHasSuffix shortcut
func CmpHasSuffix(t TestingT, got any, expected string, args ...any) bool
CmpHasSuffix is a shortcut for:
td.Cmp(t, got, td.HasSuffix(expected), 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.
