Introduction to Laravel Dusk: Testing Todo App

Updated on  6th April

8 Min Read
Reading Time: 8 minutes

In the previous part of this series, I completed the ToDo app. Today, I am going to test this app using Laravel Dusk. I will start this article with a brief introduction of Laravel Dusk, how you can setup Laravel Dusk and then go into the process of testing the ToDo application.

Laravel Dusk Test ToDo App

What is Laravel Dusk?

Laravel Dusk is a browser automation testing tool introduced in Laravel 5.4. It is the perfect tool for browser testing applications and API. It uses ChromeDriver by default but you can use any Selenium compatible drivers.

Install Laravel Dusk

Laravel Dusk can be installed by running the following command:

Once the installation finishes, I will register it inside the register() method in AppServiceProvider. For this, go to app/Providers folder and open AppServiceProvider.php file. Add the following line right before the start of the class:

Next, in the register() method, paste the following code:

At this point, AppServiceProvider class will look like this:

Now, run the following command to install Laravel Dusk:

Once the command is completed, the Browser directory will be created inside the tests directory (this will contain an Example Test file). In this directory, I will create all the tests for browser automation.

Next, I will describe the testing process of the ToDo app.

Creating Browser Test Cases for the ToDo App

I will use the default browser (Chrome) for the tests.

First of all, run the following command to create a new Test file:

Once the command finishes, it will create a new test file with the name TodoTest inside the Browser directory. This file will contain an example test case method testExample(). Remove this method from the file.

Before I start adding the methods for test cases, open .env file and add the full app URL in the  APP_URL constant.

Now, I could start writing the test cases.

User Registration Test

I will begin by creating a new test function which will test user registration process and check whether the user is redirected to the dashboard.

Inside the TodoTest class, create a new function with the name testRegister(). Paste the following code in it:

In the above code, I called the browse method along with the $browser instance, which is automatically passed by Dusk and used to make assertion for the application. First, I used the  visit() method to direct browser to the register page. Then, in the type method, I first defined the name of the input field and after the comma, I assigned its value. Since I am using a file input type in the registration form, I have used the attach method to attach the file to the input. I entered the name of the type file input field and then defined the path where the image is saved at the local machine. Next, I used press (used to press the button on the web page). Inside this, I defined the button to press (in this case, it is Register). Finally, I checked the assert that the user is redirected to dashboard i.e. ‘/todo/’ by using the assertPathIs method. I need to add the full URL, as shown in the browser after the ‘localhost’, i.e. ‘/todoapplaravel/public/todo’.

Create a New ToDo Test

Now, create a new method with the name testCreateTodo(). Add the following code in it.

After redirecting to the ‘todo’, I have used clickLink method to click on the add todo, since it is a link, not a button. Next, I added todo input values. Once done, I pressed the Add button. Next, I am asserting that it is redirected to the dashboard. The todo item has been added successfully. If not, then assert would fail.

View the Todo Test

Before creating this test, I need to edit the dashboard.php file. I will add an id to all the icons so that I can click them using the automation testing. For this, go to the resources/views/todo directory and open the dashboard.php file. Now, replace the code in this file with the following:

In the above code, I gave an id to the view,edit & delete. This is a  concatenation of the view and the id of a todo i.e. id="view{{$todo->id}}” for view, id="edit{{$todo->id}}" for edit and id="delete{{$todo->id}}" for delete.

Now, I will create the todo test for viewing todo. For this, go to the TodoTest.php file and add a new method testViewTodo() with the following code:

In the above code, I first visited ‘todo’ and then asserted that id #view1 exists in the dashboard. Then, I visited this link using the visit method. Inside this method, I defined which attribute to click using the attribute method. Next, I asserted its path. If it is valid, I called the clickLink method to click on the Edit link, which is visible on that page. Next, I have edited its description using the type method and then pressed the Update button using the press method. Next, I  checked the path again to see that it redirect back to the same todo or not using assertPathis method.

Edit the Todo Test

Now, create a new function with name the testEditTodo. Add the following code to it:

In The above code, I first redirected to the dashboard and then clicked the edit icon, updated the todo description and then asserted that the path is same or not.

Delete a Todo Test

Now, create a new function with the name testDeleteTodo. Add the following code to it:

Logout Test

Now, create a new function with the name testLogout() and add the following code to it:

Login Test

After registration, the user is automatically redirected to Login page. That’s why, I have not created the login test before. Now, create a new function with the name testLogin and paste the following code in it:

At this point, all the test cases for the ToDo app have been created. The complete TodoTest file will look like the following:


This test case file has been added to the todo app Laravel repo on the GitHub.

One Command To Test Them All

On the command line, run the following command to run the automation tests:

Concluding The Series

In this series on the Laravel powered ToDo application, I started with setting up migration tables, controller and models. Then, I created user authentication, views and setup ToDo functionality. In this final part of the series, I carried out browser testing of Laravel applications using Laravel Dusk. Feel free to give your feedback on this series in the comments section below.
