RhymesTesting validation rules can become quite tiresome pretty quickly if you have to write each test manually. For this example we have a form that allows a user to update their profile information with a Livewire ProfileForm component.In Livewire you can define validation rules by setting a rules array (shown below) and then validate using $this->validate().

Here are the rules we have set and the save() method that will validate the input.// App\Http\Livewire\ProfileForm.phpuseIlluminate\Validation\Rule;protectedfunctionrules(){return['user.id'=>'required','user.name'=>'required|max:200','user.email'=>['required','email',Rule::unique('users')->ignore($this->user->id)],'user.bio'=>'required|min:20|max:1000',];}publicfunctionsave(){$this->validate();// Save the user data$this->user->save();}So how can we go about testing each of these rules? There are 8 different validation rules in this simple example, but you don’t want to have to write 8 separate tests for each rule.

In our case we are passing in the field, the value and the rule./** * @test * @dataProvider validationRules **/publicfunctiontest_validation_rules($field,$value,$rule){}Testing the Livewire validation rulesNow we are ready to test the validation rules in the Livewire component.
