Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
Mocking framework for Laravel Echo
npm i mock-echo
Import mock-echo
import MockEcho from 'mock-echo'
Replace global object Echo
with new MockEcho()
before every unit test
let mockEcho
beforeEach(() => {
mockEcho = new MockEcho()
global.Echo = mockEcho
})
Remember to delete global object Echo
after every unit test
afterEach(() => {
delete global.Echo
})
You can use channelExist
, privateChannelExist
or presenceChannelExist
to determine whether channel has been listened:
channelExist
: channelprivateChannelExist
: private channelpresenceChannelExist
: presence channelExample:
expect(mockEcho.channelExist('news')).toBe(true)
expect(mockEcho.privateChannelExist('meeting')).toBe(true)
expect(mockEcho.presenceChannelExist('chat')).toBe(true)
All examples are using
expect
as assertion library
You can use getChannel
, getPrivateChannel
, getPresenceChannel
to get mock channel object
getChannel
: channelgetPrivateChannel
: private channelgetPresenceChannel
: presence channelMock channel object has functions eventExist
, broadcast
, etc.
Example:
expect(mockEcho.getChannel('news').eventExist('NewsMessage')).toBe(true)
You can use getChannel(channelName).eventExist
, getPrivateChannel(channelName).eventExist
or getPresenceChannel(channelName).eventExist
to determine whether event has been listened:
getChannel(channelName).eventExist
: channelgetPrivateChannel(channelName).eventExist
: private channelgetPresenceChannel(channelName).eventExist
: presence channelExample:
expect(mockEcho.getChannel('news').eventExist('NewsMessage')).toBe(true)
expect(mockEcho.getPrivateChannel('meeting').eventExist('MeetingMessage')).toBe(true)
expect(mockEcho.getPresenceChannel('chat').eventExist('ChatMessage')).toBe(true)
You can use broadcast
to broadcast an event.
Note: If you are using
vue-test-utils
, call$nextTick
before assertion.
Example:
mockEcho.getChannel('news').broadcast('NewsMessage', { message: 'Hello World' })
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.message').text()).toBe('It said Hello World')
done()
})
You can use iJoin
, userJoin
, userLeave
to trigger presence channel actions:
iJoin
: trigger here
listeneruserJoin
: trigger joining
listner. It will return subId
after calling userJoin
. You can use this subId
to get this user away from this channel.userLeave
: trigger leaving
listner. Use subId
which got from userJoin
to get this user away from this channel.Note: If you are using
vue-test-utils
, call$nextTick
before assertion.
Example:
mockEcho.getPresenceChannel('chat').iJoin({id: 1, name: 'Alex'})
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.here-message').text()).toBe('There are 1 users')
done()
})
// You will need paulSubId to get this user away from this channel
let paulSubId = mockEcho.getPresenceChannel('chat').userJoin({id: 2, name: 'Paul'})
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.join-message').text()).toBe('Paul joined')
done()
})
mockEcho.getPresenceChannel('chat').userLeave(paulSubId)
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.leave-message').text()).toBe('Paul leaved')
done()
})
You can use userWhisper
to send user event. Only private channel object and presence channel object have userWhisper
.
Note: If you are using
vue-test-utils
, call$nextTick
before assertion.
Example:
// private channel
mockEcho.getPrivateChannel('meeting').userWhisper('meetingClicking', { username: username })
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.whisper-message').text()).toBe(`${username} is clicking the button`)
done()
})
// presence channel
mockEcho.getPresenceChannel('chat').userWhisper('chatClicking', { username: username })
wrapper.vm.$nextTick(() => {
expect(wrapper.find('.whisper-message').text()).toBe(`${username} is clicking the button`)
done()
})
