Functions

func Equal

func Equal(t *testing.T, expected, actual interface{})

Equal is a test assertion used to check equality.

func Fail

func Fail(t *testing.T, args ...interface{})

Fail fails the test with the given message.

func NotEqual

func NotEqual(t *testing.T, v1, v2 interface{})

NotEqual is a test assertion used to check non-equality.

func NotNil

func NotNil(t *testing.T, val interface{})

NotNil is a test assertion that checks for both nil values and js.Undefined.

Types

type Matcher

type Matcher struct {
	// contains filtered or unexported fields
}

Matcher used to find a component in the component tree.

func NewMatcher

func NewMatcher(key, value string) Matcher

NewMatcher creates a new matcher.

type RenderedTree

type RenderedTree struct {
	*js.Object

	GetMountedInstance func() *js.Object `js:"getMountedInstance"`

	Text func() string `js:"text"`
	// fillField: [Function],
	//findComponent: [Function],
	//findComponentLike: [Function],
	GetRenderOutput func() map[string]interface{} `js:"getRenderOutput"`

	Props *js.Object `js:"props"`
	Type  string     `js:"type"`
	// contains filtered or unexported fields
}

RenderedTree represents a shallow render.

func ShallowRender

func ShallowRender(c gr.Component) *RenderedTree

ShallowRender performs a shallow render of the given component.

func ShallowRenderWithContext

func ShallowRenderWithContext(c gr.Component, ctx gr.Context) *RenderedTree

ShallowRenderWithContext performs a shallow render with the given context.

func (*RenderedTree) CallEventListener

func (t *RenderedTree) CallEventListener(name string, args ...interface{}) *js.Object

CallEventListener is a convenience func to simulate button clicks etc. by calling the listener methods by name.

func (*RenderedTree) Dive

func (t *RenderedTree) Dive(path ...string) *RenderedTree

Dive can be used to render a sub-component.

func (*RenderedTree) ReRender

func (t *RenderedTree) ReRender(props gr.Props)

ReRender rerenders a component with new properties.

func (*RenderedTree) String

func (t *RenderedTree) String() string

String represents a shallow rendered component. This is in heavy use in assertions, so we try to keep it stable.

func (*RenderedTree) Sub

func (t *RenderedTree) Sub(selector string, matchers ...Matcher) *RenderedTree

Sub returns a sub component matching the matchers.

func (*RenderedTree) This

func (t *RenderedTree) This() *gr.This

This returns the this context of a shallow render.
