Functions

func ArgsAfterT

func ArgsAfterT(args []ast.Expr) []ast.Expr

ArgsAfterT selects args starting at position 1. Used when the caller has a testing.T as the first argument, and the args to select should follow it.

func ArgsAtZeroIndex

func ArgsAtZeroIndex(args []ast.Expr) []ast.Expr

ArgsAtZeroIndex selects args from the CallExpression at position 1. Used when the caller accepts a single cmp.Comparison argument.

func ArgsFromComparisonCall

func ArgsFromComparisonCall(args []ast.Expr) []ast.Expr

ArgsFromComparisonCall selects args from the CallExpression at position 1. Used when the caller has a testing.T as the first argument, and the args to select are passed to the cmp.Comparison at position 1.

func Eval

func Eval(
	t LogT,
	argSelector argSelector,
	comparison interface{},
	msgAndArgs ...interface{},
) bool

Eval the comparison and print a failure messages if the comparison has failed.

func RunComparison

func RunComparison(
	t LogT,
	argSelector argSelector,
	f cmp.Comparison,
	msgAndArgs ...interface{},
) bool

RunComparison and return Comparison.Success. If the comparison fails a messages will be printed using t.Log.

Types

type LogT

type LogT interface {
	Log(args ...interface{})
}

LogT is the subset of testing.T used by the assert package.
