Types

type ConditionType

type ConditionType int

ConditionType is the type of condition for matcher

const (
	// ANDCondition matches responses with AND condition in arguments.
	ANDCondition ConditionType = iota + 1
	// ORCondition matches responses with AND condition in arguments.
	ORCondition
)

type Matcher

type Matcher struct {
	// description: |
	//   Type is the type of the matcher.
	Type MatcherTypeHolder `` /* 154-byte string literal not displayed */
	// description: |
	//   Condition is the optional condition between two matcher variables. By default,
	//   the condition is assumed to be OR.

	// description: |
	//   Part is the part of the request response to match data from.
