Modern businesses bank heavily on technology to offer their services and products, which makes it critical to ensure that these solutions are high-performing and optimized for the best user experience. In this context, frontend testing stands out as a significant factor to ensure usability, effective bandwidth consumption, optimal loading speed, and generally quality user experience.
In this write-up, we delve deeper into frontend testing, its importance, it’s application, and best practices.
Understanding Frontend Testing
Frontend, in the simplest terms, refers to the development of a website’s graphical user interface (GUI). This involves using diverse technologies like HTML, CSS, and JavaScript to create an interactive user interface.
Frontend testing, therefore, is the series of validations performed to test the application’s GUI’s functionality and usability. It includes the validation of various application elements visible to end-users, like menus, forms, and buttons.
The Criticality of Frontend Testing
Frontend tests provide your app with robust defense against regression. It validates that the new code you deploy will not crash any other part of the application. This balance between adding new features and maintaining the existing ones only becomes more challenging as the complexity of the application increases.
Frontend tests yield live documentation since they need a proper description of the specific test and the component of your application it relates to. This information then serves as guidelines for other developers in the future.
Frontend Testing Challenges
When executing frontend tests, a couple of challenges might be encountered including
- Determining the most crucial frontend elements to test
- Simulate the real-world environment
- Selection of suitable testing tools
- Accounting for human factors
Practices To Follow in Frontend Testing
The F.I.R.S.T. principles (Fast, Isolated/Independent, Repeatable, Self-validating, Thorough) provide a useful framework in ensuring frontend testing is appropriately done. Tests should be done speedily, isolated from untested components, be easily repeatable, and able to validate themselves.
Types of Frontend Tests
Frontend testing provides different types of tests that can help provide comprehensive insights into your applications. These include unit testing, acceptance testing, visual regression testing, accessibility testing, performance testing, end-to-end (E2E) testing, integration testing, and cross-browser testing.
Tools for Frontend Testing
Effective frontend testing requires the use of various testing tools and kits. Some of the most popular include Jest, Selenium WebDriver, Cypress, WebDriverIO, WebDriverJS, and TestCafe.
Frontend Testing Plan
It’s useful to define a budget and choose suitable tools before you start testing. Afterward, set a realistic timeline for the project and, equally crucial, define the scope of your project.
In conclusion, frontend testing is a vital aspect of the software development cycle. It assures that the end products delivered to the customers are functional and provide the best user experience.
