tst

Error asserting functions for table driven testcases.

Examples:

	err := errors.New("not found")

	tests := []struct {
		input    error
		asserter ErrorAssertionFunc
	}{
		{
			input:    nil,
			asserter: NoError(),
		},
		{
			input:    err,
			asserter: Error(),
		},
		{
			input:    err,
			asserter: ErrorIs(err),
		},
		{
			input:    fmt.Errorf("wrapped %w", err),
			asserter: ErrorIs(err),
		},
		{
			input:    &os.PathError{},
			asserter: ErrorOfType[*os.PathError](),
		},
		{
			input: &os.PathError{Op: "op", Path: "/abc", Err: os.ErrInvalid},
			asserter: ErrorOfType[*os.PathError](
				func(tt TestingT, pe *os.PathError) { assert.Equal(tt, "op", pe.Op) },
			),
		},
		{
			input: fmt.Errorf("wrapped %w", &os.PathError{Op: "op", Path: "/abc", Err: os.ErrInvalid}),
			asserter: All(
				Error(),
				ErrorIs(os.ErrInvalid),
				ErrorOfType[*os.PathError](
					func(tt TestingT, pe *os.PathError) { assert.Equal(tt, "op", pe.Op) },
				),
				ErrorStringContains("op"),
			),
		},
	}
