This Package Adds Missing Livewire Test Assertions

This package adds some nice new Livewire assertions which I was missing while testing my applications using Livewire. If you want to know more about WHY I needed them, check out my blog article.

➡️ Version 2.0 of this package only supports Livewire 3. Please use a lower version of this package for other Livewire versions.

Installation

You can install the package via composer:

composer require christophrumpel/missing-livewire-assertions

Usage

The new assertions get added automatically, so you can use them immediately.

Check if a Livewire property is wired to an HTML field

Livewire::test(FeedbackForm::class)
    ->assertPropertyWired('email');

It looks for a string like wire:model="email" in your component's view file. It also detects variations like wire:model.live="email", wire:model.lazy="email", wire:model.debounce="email", wire:model.lazy.10s="email" or wire:model.debounce.500ms="email".

Check if a Livewire method is wired to an HTML field

Livewire::test(FeedbackForm::class)
    ->assertMethodWired('submit');

It looks for a string like wire:click="submit" in your component's view file.

Check if a Livewire magic action is wired to an HTML field

Livewire::test(FeedbackForm::class)
    ->assertMethodWired('$toggle(\'sortAsc\')');

Check if a generic Livewire method is wired to an HTML field

Livewire::test(FeedbackForm::class)
    ->assertMethodWiredToAction('mouseenter', 'enter');

It looks for a string like wire:mouseenter="enter" in your component's view file. Also, note that it can also look for any events, like wire:keydown or wire:custom-event.

It looks for a string like wire:click="$refresh", wire:click="$toggle('sortAsc'), $dispatch('post-created'), along with all other magic actions. When testing for magic actions, you must escape single quotes like shown above.

Check if a Livewire method is wired to an HTML form

Livewire::test(FeedbackForm::class)
    ->assertMethodWiredToForm('upload');

It looks for a string like wire:submit.prevent="upload" in your component's view file.

Check if a Livewire method is wired to a specific javascript event

Livewire::test(FeedbackForm::class)
    ->assertMethodWiredToEvent('setValue', 'change');

It looks for a string like wire:change.debounce.150ms="setValue" in your component's view file.

You can also check for actions without any additional modifiers:

Livewire::test(FeedbackForm::class)
    ->assertMethodWiredToEventWithoutModifiers('reset', 'keyup');

This will match wire:keyup="reset", but not wire:keyup.escape="reset". You could match that with

Livewire::test(FeedbackForm::class)
    ->assertMethodWiredToEventWithoutModifiers('reset', 'keyup.escape');

Check if a Livewire component contains another Livewire component

Livewire::test(FeedbackForm::class)
    ->assertContainsLivewireComponent(CategoryList::class);

You can use the component tag name as well:

Livewire::test(FeedbackForm::class)
    ->assertContainsLivewireComponent('category-list');

Check if a Livewire component contains a Blade component

Livewire::test(FeedbackForm::class)
    ->assertContainsBladeComponent(Button::class);

You can use the component tag name as well:

Livewire::test(FeedbackForm::class)
    ->assertContainsBladeComponent('button');

Check to see if a string comes before another string

Livewire::test(FeedbackForm::class)
    ->assertSeeBefore('first string', 'second string');
