Functions

func Compare 

func Compare(a string, e string) bool

Compare compares two strings, a for actual, e for expected, and returns true or false. The comparison is done, by filtering out whitespace (i.e. space, tabs and newline).

func DiffMessage 

func DiffMessage(context string, actual interface{}, expected interface{}) string

DiffMessage creates a diff dump message for test failures.

func ExprCall 

func ExprCall(id int64, function string, args ...*exprpb.Expr) *exprpb.Expr

ExprCall creates a call Expr.

func ExprComprehension 

func ExprComprehension(id int64,
	iterVar string, iterRange *exprpb.Expr,
	accuVar string, accuInit *exprpb.Expr,
	loopCondition *exprpb.Expr, loopStep *exprpb.Expr,
	resultExpr *exprpb.Expr) *exprpb.Expr

ExprComprehension returns a comprehension Expr.

func ExprEntry 

func ExprEntry(id int64, key *exprpb.Expr,
	value *exprpb.Expr) *exprpb.Expr_CreateStruct_Entry

ExprEntry creates a map entry for a create struct Expr.

func ExprField 

func ExprField(id int64, field string,
	value *exprpb.Expr) *exprpb.Expr_CreateStruct_Entry

ExprField creates a field entry for a create struct Expr.

func ExprIdent 

func ExprIdent(id int64, name string) *exprpb.Expr

ExprIdent creates an ident (variable) Expr.

func ExprList 

func ExprList(id int64, elements ...*exprpb.Expr) *exprpb.Expr

ExprList creates a create list Expr.

func ExprLiteral 

func ExprLiteral(id int64, value interface{}) *exprpb.Expr

ExprLiteral creates a literal (constant) Expr.

func ExprMap 

func ExprMap(id int64, entries ...*exprpb.Expr_CreateStruct_Entry) *exprpb.Expr

ExprMap creates a create struct Expr for a map.

func ExprMemberCall 

func ExprMemberCall(id int64, function string, target *exprpb.Expr, args ...*exprpb.Expr) *exprpb.Expr

ExprMemberCall creates a receiver-style call Expr.

func ExprSelect 

func ExprSelect(id int64, operand *exprpb.Expr, field string) *exprpb.Expr

ExprSelect creates a select Expr.

func ExprType 

func ExprType(id int64, messageName string,
	entries ...*exprpb.Expr_CreateStruct_Entry) *exprpb.Expr

ExprType creates creates a create struct Expr for a message.

Types

type TestExpr 

type TestExpr struct {
	Expr       *exprpb.Expr
	SourceInfo *exprpb.SourceInfo
}

TestExpr packages an Expr with SourceInfo, for testing.

func (*TestExpr) Info 

func (t *TestExpr) Info(location string) *exprpb.SourceInfo

Info returns a copy of the SourceInfo with the given location.
