Functions

func CanReuseSession

func CanReuseSession(caps *Capabilities) bool

CanReuseSession returns true if the "google:canReuseSession" is set.

func Merge

func Merge(m1, m2 map[string]interface{}) map[string]interface{}

Merge takes two JSON objects, and merges them.

The resulting object will have all of the keys in the two input objects. For each key that is in both objects:

  • if both objects have objects for values, then the result object will have a value resulting from recursively calling Merge.
  • if both objects have lists for values, then the result object will have a value resulting from concatenating the two lists.
  • Otherwise the result object will have the value from the second object.

func NoOPResolver

func NoOPResolver(prefix, name string) (string, error)

NoOPResolver resolves to %prefix:name%.

Types

type Capabilities

type Capabilities struct {
	AlwaysMatch  map[string]interface{}
	FirstMatch   []map[string]interface{}
	W3CSupported bool
}

Capabilities is a WebDriver capabilities object. It is modeled after W3C capabilities, but supports use as W3C, JWP, or mixed-mode.

func FromNewSessionArgs

func FromNewSessionArgs(args map[string]interface{}) (*Capabilities, error)

FromNewSessionArgs creates a Capabilities object from the arguments to new session. AlwaysMatch will be the result of merging alwaysMatch, requiredCapabilities, and desiredCapabilities. Unlike Metadata capabilities merging and MergeOver, this is a shallow merge, and any conflicts will result in an error. Additionally if any capability in firstMatch conflicts with a capability in alwaysMatch, requiredCapabilities, or desiredCapabilities, an error will be returned.

func (*Capabilities) MergeOver

func (c *Capabilities) MergeOver(other map[string]interface{}) *Capabilities

MergeOver creates a new Capabilities with AlwaysMatch == (c.AlwaysMatch deeply merged over other), FirstMatch == c.FirstMatch, and W3Supported == c.W3CSupported.

func (*Capabilities) Resolve

func (c *Capabilities) Resolve(resolver Resolver) (*Capabilities, error)

Resolve returns a new Capabilities object with all %PREFIX:NAME% substrings replaced using resolver.

func (*Capabilities) Strip

func (c *Capabilities) Strip(capsToStrip ...string) *Capabilities

Strip returns a copy of c with all top-level capabilities capsToStrip and with nil values removed.

func (*Capabilities) ToJWP

func (c *Capabilities) ToJWP() (map[string]interface{}, error)

ToJWP creates a map suitable for use as arguments to a New Session request for JSON Wire Protocol remote ends. Since JWP does not support an equivalent to FirstMatch, if FirstMatch contains more than 1 entry then this returns an error (if it contains exactly 1 entry, it will be merged over AlwaysMatch).

func (*Capabilities) ToMixedMode

func (c *Capabilities) ToMixedMode() map[string]interface{}

ToMixedMode creates a map suitable for use as arguments to a New Session request for arbitrary remote ends. If FirstMatch contains more than 1 entry then this returns W3C-only capabilities. If W3CSupported is false then this will return JWP-only capabilities.

func (*Capabilities) ToW3C

func (c *Capabilities) ToW3C() map[string]interface{}

ToW3C creates a map suitable for use as arguments to a New Session request for W3C remote ends.

type Resolver

type Resolver func(prefix, name string) (string, error)

A Resolver resolves a prefix, name pair to a replacement value.

func MapResolver

func MapResolver(prefix string, names map[string]string) Resolver

MapResolver returns a new Resolver that uses key-value pairs in names to resolve names for prefix, and otherwise uses the NoOPResolver.
