Types

type Runtime

type Runtime struct {
	VU             *VU
	EventLoop      *eventloop.EventLoop
	CancelContext  func()
	BuiltinMetrics *metrics.BuiltinMetrics
	// contains filtered or unexported fields
}

Runtime is a helper struct that contains what is needed to run a (simple) module test

func NewRuntime

func NewRuntime(t testing.TB) *Runtime

NewRuntime will create a new test runtime and will cancel the context on test/benchmark end

func (*Runtime) MoveToVUContext

func (r *Runtime) MoveToVUContext(state *lib.State)

MoveToVUContext will set the state and nil the InitEnv just as a real VU

func (*Runtime) RunOnEventLoop

func (r *Runtime) RunOnEventLoop(code string) (value goja.Value, err error)

RunOnEventLoop will run the given code on the event loop.

It is meant as a helper to test code that is expected to be run on the event loop, such as code that returns a promise.

A typical usage is to facilitate writing tests for asynchrounous code:

func TestSomething(t *testing.T) {
    runtime := modulestest.NewRuntime(t)

    err := runtime.RunOnEventLoop(`
        doSomethingAsync().then(() => {
            // do some assertions
        });
    `)
    require.NoError(t, err)
}

func (*Runtime) SetupModuleSystem

func (r *Runtime) SetupModuleSystem(goModules map[string]any, loader modules.FileLoader, c *compiler.Compiler) error

SetupModuleSystem sets up the modules system for the Runtime. See modules.NewModuleResolver for the meaning of the parameters.

func (*Runtime) SetupModuleSystemFromAnother

func (r *Runtime) SetupModuleSystemFromAnother(another *Runtime) error

SetupModuleSystemFromAnother sets up the modules system for the Runtime by using the resolver of another runtime.

type VU

type VU struct {
	CtxField              context.Context
	InitEnvField          *common.InitEnvironment
	EventsField           common.Events
	StateField            *lib.State
	RuntimeField          *goja.Runtime
	RegisterCallbackField func() func(f func() error)
}

VU is a modules.VU implementation meant to be used within tests

func (*VU) Context

func (m *VU) Context() context.Context

Context returns internally set field to conform to modules.VU interface

func (*VU) Events

func (m *VU) Events() common.Events

Events returns internally set field to conform to modules.VU interface

func (*VU) InitEnv

func (m *VU) InitEnv() *common.InitEnvironment

InitEnv returns internally set field to conform to modules.VU interface

func (*VU) RegisterCallback

func (m *VU) RegisterCallback() func(f func() error)

RegisterCallback is not really implemented

func (*VU) Runtime

func (m *VU) Runtime() *goja.Runtime

Runtime returns internally set field to conform to modules.VU interface

func (*VU) State

func (m *VU) State() *lib.State

State returns internally set field to conform to modules.VU interface
