be_reflected
– import “github.com/expectto/be/be_reflected”
Package be_reflected provides Be matchers that use reflection, enabling expressive assertions on values’ reflect kinds and types. It consists of several “core” matchers e.g. AsKind / AssignableTo / Implementing And many other matchers that are made on-top on core ones. E.g. AsFunc / AsString / AsNumber /
etc
Usage
func AsBytes
func AsBytes() types.BeMatcher
AsBytes succeeds if actual is assignable to a slice of bytes ([]byte).
func AsChan
func AsChan() types.BeMatcher
AsChan succeeds if actual is of kind reflect.Chan.
func AsFinalPointer
func AsFinalPointer() types.BeMatcher
AsFinalPointer succeeds if the actual value is a final pointer, meaning it’s a pointer to a non-pointer type.
func AsFloat
func AsFloat() types.BeMatcher
AsFloat succeeds if actual is a numeric value that represents a floating-point value.
func AsFloatString
func AsFloatString() types.BeMatcher
AsFloatString succeeds if actual is a string that can be parsed into a valid floating-point value.
func AsFunc
func AsFunc() types.BeMatcher
AsFunc succeeds if actual is of kind reflect.Func.
func AsInteger
func AsInteger() types.BeMatcher
AsInteger succeeds if actual is a numeric value that represents an integer (from reflect.Int up to reflect.Uint64).
func AsIntegerString
func AsIntegerString() types.BeMatcher
AsIntegerString succeeds if actual is a string that can be parsed into a valid integer value.
func AsKind
func AsKind(args ...any) types.BeMatcher
AsKind succeeds if actual is assignable to any of the specified kinds or matches the provided matchers.
func AsMap
func AsMap() types.BeMatcher
AsMap succeeds if actual is of kind reflect.Map.
func AsNumber
func AsNumber() types.BeMatcher
AsNumber succeeds if actual is a numeric value, supporting various integer kinds: reflect.Int, … reflect.Int64, and floating-point kinds: reflect.Float32, reflect.Float64
func AsNumericString
func AsNumericString() types.BeMatcher
AsNumericString succeeds if actual is a string that can be parsed into a valid numeric value.
func AsObject
func AsObject() types.BeMatcher
AsObject is more specific than AsMap. It checks if the given actual value is a
map with string keys and values of any type. This is particularly useful in the
context of BeJson matcher, where the term ‘Object’ aligns with JSON notation.
func AsObjects
func AsObjects() types.BeMatcher
func AsPointer
func AsPointer() types.BeMatcher
AsPointer succeeds if the actual value is a pointer.
func AsPointerToMap
func AsPointerToMap() types.BeMatcher
AsPointerToMap succeeds if actual is a pointer to a map.
func AsPointerToObject
func AsPointerToObject() types.BeMatcher
AsPointerToObject succeeds if actual is a pointer to a value that matches AsObject after applying dereference.
func AsPointerToSlice
func AsPointerToSlice() types.BeMatcher
AsPointerToSlice succeeds if actual is a pointer to a slice.
func AsPointerToStruct
func AsPointerToStruct() types.BeMatcher
AsPointerToStruct succeeds if actual is a pointer to a struct.
func AsReader
func AsReader() types.BeMatcher
AsReader succeeds if actual implements the io.Reader interface.
func AsSlice
func AsSlice() types.BeMatcher
AsSlice succeeds if actual is of kind reflect.Slice.
func AsSliceOf
func AsSliceOf[T any]() types.BeMatcher
AsSliceOf succeeds if actual is of kind reflect.Slice and each element of the slice is assignable to the specified type T.
func AsString
func AsString() types.BeMatcher
AsString succeeds if actual is of kind reflect.String.
func AsStringer
func AsStringer() types.BeMatcher
AsStringer succeeds if actual implements the fmt.Stringer interface.
func AsStruct
func AsStruct() types.BeMatcher
AsStruct succeeds if actual is of kind reflect.Struct.
func AssignableTo
func AssignableTo[T any]() types.BeMatcher
AssignableTo succeeds if actual is assignable to the specified type T.
func Implementing
func Implementing[T any]() types.BeMatcher
Implementing succeeds if actual implements the specified interface type T.
