Before we understand the dynamics involved in Nuxt testing, let us first try and understand Nuxt.js and how important Nuxt testing is.

Nuxt.js is a free, open-source front-end framework built using Vue.js, which is great from a development perspective. It has simplified the way we approach web development. It allows the application developers to be flexible when using it as a main project base. This framework is commonly known as a meta-framework for universal applications. It enables the user to view content or part of pre-rendered content and server on a static site.

In this blog on Nuxt testing, let’s get deeper into what made Nuxt.js a developer favorite and how to get started with cross browser testing for Nuxt.js applications with regards to Nuxt testing.

What has captivated the audience towards Nuxt.js applications?

Nuxt.js is winning laurels among the business audience. There are umpteen reasons for its success, be it simplified options to conduct web testing in case of Nuxt testing or advanced usability features.

Some of its unique features are:

  • Server-side rendering.
  • Improved SEO performance.
  • Improvements in managing the meta tags.

Here are the top reasons why Nuxt.js is a great choice for your next web applications:

  • Create universal web applications without any hassles.
  • The same code can be shared between the client and server so that you can focus on the overall logic related to the web application.
  • It provides access to various properties such as isClient and isServer so that it can be pre-decided if the rendering is performed on either client or server.
  • It provides a starter template to help you start a project.
  • You can manage your code structure in the best possible manner. This means that there are no hassles when it comes to organizing your web application.

How does the Nuxt.js framework work?

The Nuxt.js maintains its contents in a folder structure mechanism. This means that some different folders and files will be used to get the work done. If you are a newbie developer who is not familiar, then it is important to understand the folder structure before you start practically implementing the concepts.

These are the following elements that you should be aware of before you move on to Nuxt testing.

  • Assets: This is the folder where you can see all the un-compiled files such as font files, images, JS files, etc.
  • Components: This contains all the reusable components the developers can create
  • Layouts: This allows you to store the application-specific layouts. This can be useful when designing an application with different layout requirements.
  • Middleware: This is the folder where you can place your essential JS files before a page is rendered.
  • Pages: This is a folder specific to developer use.
  • Plugins: This folder allows storing files that should be running before mounting the Vue.js root application.
  • nuxt.config.js: This file allows you to handle configuration settings for your application.
  • Mode: This represents the type of the app.
  • Loading: This is the default nuxt.js loader component.

Application Types Supported in Nuxt.js

Before we delve deeper into Nuxt testing, It allows developers to create three different application types, depending upon the development requirements:

  • Static Generated Pages
  • These applications do not require any API requests to fetch page content, which means that most of the content is already available in the HTML file itself. A great example of a static site is a product landing page where the content is already available once loaded.

  • Single Page Application
  • Most JavaScript frameworks like Angular, React, etc. are single-page applications with content populated with fast transitions. You can use HTML5 history API or location hash for routing purposes.

  • Server-Side Rendering
  • This is a technique developers use to display and fetch client-side data on the server.

Limitations of Nuxt.js framework

Here are some limitations you should know before using the Nuxt.js framework for web development.

  • It has a smaller community, which means that there are fewer resources available online. The product documentation also needs improvement in the long run.
  • The overall high traffic can impact the server performance.
  • Some of the solid plugins or components must be maintained well so that third-party integrations can be performed seamlessly.

Differences Between Vue and Nuxt Frameworks

We discussed how the Nuxt.js framework offers great benefits for front-end development. But two frameworks are being talked about. These two frameworks handle the logic differently. Vue is running on the client-side while Nuxt is not. Nuxt.js applications were not a preferred choice in the past as they faced a lot of criticism from experts that it is not ready for enterprise-scale apps.

However, it has improved on its existing capabilities and has made a mark on the development ecosystem. There will always be challenges when you are trying to implement any new framework, but once you are familiar with the functionalities, then it becomes a lot easier to execute the concepts in real-time. Some features such as better SEO, faster development, and automatic code-splitting, which are possible with the Nuxt framework, are not possible with the Vue framework.

Different approaches to test Nuxt.js applications

Cross browser testing has gained a lot of recognition in the past few years. It is a method of quality assurance that can be used to perform web application testing across multiple browsers. This is done to ensure that the overall functionality is validated across a range of devices and operating systems to check its compatibility.

It ensures:

  • The look and feel of the pages remain the same in different browsers.
  • The overall functionality is working as expected.

Cross browser testing is usually performed by the QA team, who knows the functionality testing aspects. Other stakeholders can also contribute to this activity if the need arises.

Nuxt testing can be performed in two ways:

  • Manual Testing
  • Automated Testing

Manual testing is all about identifying bugs by executing the test cases on different browsers and operating systems manually. The bugs reported are closed during that iteration. It is impossible to cover all the major browsers, and this can be time-consuming and costly.

Automated testing involves executing the same set of test cases multiple times on different browsers. This fast and effective approach where automation testing tools can save time and effort. If you are looking to perform cross browser testing, then this is the best approach going forward.

Different methodologies to test Nuxt.js applications

Apart from using the specialized cross-browser testing platform, other supported methods can be implemented for testing the Nuxt.js application. The following three types of Nuxt testing can be performed:

  • Unit Testing: Unit testing is performed by developers to test the procedures or impacted functionalities. You can use many unit testing frameworks to perform it.
  • Component Testing: Component testing is used to perform usability testing of each component.
  • End-to-End(E2E) Testing: In end-to-end testing, you perform the testing of the entire application from start to finish.

How to perform Nuxt testing using Playwright?

You can use the Playwright framework to perform cross browser testing of your Nuxt.js application. You can use Playwright as a testing framework for your testing requirements, but having a basic knowledge of Nuxt.js will always be a great value add.

  1. You need to install a new Nuxt project and all the required dependencies.
  2. Once the project is installed, it is required to build a reusable component. You can always create your components by following standard coding.
  3. We are building a reusable component named as JobRoles.vue:

    We will now use the JobRoles component as a template:

    Once you run the app and view the changes in the browser, the following output is displayed:

    Job Board
    Awesome Jobs for awesome IT people
    Java developer 90000
    DevOps Developer 120000
    Reactjs Developer 21000

  4. You need to set up your test environment. Create a predefined folder structure to set up your test infrastructure.
  5. For the test run, you can add a test script to the package.json. Once the required test scripts are added, you can run your tests using the following command:

Now, you can build your end-to-end test setup with a Playwright test runner. This means you are performing browser testing instead of unit testing. You can add additional libraries based on your requirements. You can start writing your tests.

Now you can test whether the changes related to the job board are correct or not. You can also save screenshots and even record videos that can be used for future reference. Once all the changes are validated, you can execute your tests. You can also perform automation testing for your test results so that you do not have to perform additional steps every time.

If you are new to Playwright, you can watch this video to learn how to set up the Playwright test automation framework and get started with Playwright testing.

LambdaTest is still far ahead of its competitors regarding performance and end-user experience. When you are using cloud-based technology, you can save additional costs when it comes to IT infrastructure and standalone deployments. This means you are not required to set up different teams for test design, infrastructure, and deployment. The cloud-based approach is an end-to-end solution for infrastructure and deployment requirements.

Let us try and understand how these two different testing approaches can be implemented in the LambdaTest platform:

  • Manual Cross Browser Testing
  • The manual testing approach, in contrast to the automation testing approach, is all about a human intervention that takes a lot of time and effort. You must decide on the test cases executed across multiple devices and operating systems. Once the test cases are finalized, you must execute them on different browsers and operating systems. This type of testing can be handy when the testing requirements are not that complex and you are well aware of the testing scope.

    In the case of an iterative development approach where development and testing go hand in hand, it becomes a lot more challenging to perform manual testing because the system functionality changes drastically. We can then automate our testing requirements to achieve the desired results.

  • Automation Cross Browser Testing
  • Automated browser testing leads the way in testing complex web and mobile applications. LambdaTest allows you to monitor and track your automated builds to check your application’s progress in real-time. It all comes down to choosing the right automation tool based on your testing requirements.
