Tips and Best Practices for Using Cypress, Including Strategies for Setting Up and Organizing Tests

Cypress Testing, is one of the most common practices for conducting automation testing while verifying the functioning of an application. Automation Testing helps developers get rid of exhaustive repetitive test cases. These test cases are not only time-consuming but also prone to human errors. Executing automation testing in these segments can help the developer improve the accuracy of the testing process and help them focus on other important areas of the app development project.

For instance, app developers can use this extra time to create new features that can be added to the future app version. In this article, we will discuss everything you need to know about Cypress Testing. We will also discuss some of the best tips and practices to help the developers utilize Cypress test cases the most.

Basics of Cypress

Cypress is a modern test automation tool that works on the Node.js framework. The developers can write the automation test cases in typescript or JavaScript using this tool. Since these are two of the most popular programming languages, app developers will not have any problem while transitioning to this tool.

The easy-to-use interface of Cypress is one of the significant factors that drive its popularity. The official website of Cypress has all the documentation that developers require for starting the test cases with this tool. There are also multiple sample test cases for developers to analyze and understand all the features present in this tool.

Lastly, app developers also have the liberty to integrate different third-party tools and libraries with Cypress. Now let’s discuss two of the unique features that developers will be able to use while using the Cypress tool:

  • The auto-reload feature of Cypress helps developers to automatically execute test cases after successfully serving them. It saves much time as developers do not have to search and run test cases from the terminal window manually. This is possible due to the intelligent Cypress frameworks that can understand the need for test execution after creating and saving it. Cypress offers various other intelligence features to ease the process of app testing with this tool.
  • Cypress allows developers to integrate auto-wait in the test branch. It is very important as certain framework components depend on other components for proper functioning. Therefore, using this feature, developers can pause the test case for a particular element until the completion of the previous one. This is one of the most important processes to improve the efficiency of the Cypress test cases.

Tips and Best practices for Cypress testing

Now let’s discuss some of the best tips and practices that can help the developers to utilize the most out of the Cypress test cases:

1.     Reading the Official Documentation

Many developers believe that knowing any test automation framework is enough to use all the other competitors. This is an entirely wrong belief, especially for Cypress. Cypress provides various unique features almost absent from every other test automation framework. So, the developers must have proper knowledge of all these features and tools for using the most out of the Cypress test automation case.

We recommend that developers download all the Cypress components from the official website. This is because the official website always provides the latest version and has the highest security. The official website of Cypress also has a vast community of tech enthusiasts who are always ready to help newcomers. Therefore, it is the best place for clarifying any area where the new developers might get stuck.

2.     Choosing the Best Locators

One of the common errors developers make while using Cypress automation testing is using specific selectors that are not only too prone to errors but can change frequently. Good examples of these locators are JavaScript event listeners and CSS styling. The developers can visualize these errors when they are testing the functioning of certain applications that rely heavily on user interaction.

For instance, while using these locators on web applications where the user has to click on certain elements, the application will use the element ID for clicking on it. The primary issue is that when new elements are added to it, there is no guarantee that the element will maintain the same position. In such a case, there might be various errors when the user clicks on one item, but the system returns another.

In these cases, the best practice is to locate the specific element using Cypress commands. Therefore, the developers can use CSS styling to rely on something other than the position ID. This application development is essential when creating interactive applications like an eCommerce app. It is also crucial for developers to refactor their codes.

Using the wrong locators can also increase the probability of reporting a failed test as a successful one. This is one of the significant errors of the application development process, as your final app might completely crash when released to your customers. Therefore, the developers need to have a definite idea about selecting the locators for Cypress testing.

3.     Login Programmatically

One of the standard testing practices is to log in to the application through the user interface and redirect to the web page that requires testing. The developers can complete the testing process using this method, but it could be better. This is because, with this method, the developers must rely on the UI elements to perform the authentication process.

After the UI authenticates the user action, you will be redirected to the element you want to test. This means that the developers must first ensure that their login page is working perfectly before they can verify the functioning of other elements. This means that the testing of all the elements in the web application is interdependent with this process. This style of writing test cases is different from the best practices of Cypress.

The best practice for this process is to log in programmatically. In this process, the developers must use a Cypress command called the Cypress request. Using this command, the developers can make HTTP requests outside the web browser’s jurisdiction. Any form of security restriction does not bind these requests. This means that developers can use this request to verify unstable elements’ functioning.

While performing this process, the developers should also be aware of cross-origin resource sharing. It is an HTTP header-based mechanism that allows web browsers to indicate the origin of an app and send a specific request. This feature is essential because, by default, most servers will enable the developers to only use headers from trusted sources.

4.     Maintaining the Balance in Test Automation

Considering the superiority of automation testing, one of the biggest myths in the development market is that automation testing can completely replace manual testing. This is a myth because there are specific test cases that are entirely dependent on the knowledge and experience of a human developer. For instance, exploratory testing finds specific errors in applications that are mostly overlooked by automated test cases.

On the other hand, visual testing verifies the proper placement of all the UI elements in a web application. It is impossible to verify this process with the involvement of an experienced human developer. Therefore, the most important practice in this segment is maintaining a perfect balance between automation and manual testing. It is also recommended that the developers plan all these processes during the test planning phase.

Role of Tools and Platforms in Cypress Testing

Since Cypress is relatively new to the market, the new automation testers still need to discover various features of this framework. Therefore, one of the best practices is to integrate a third-party tool or platform into your Cypress test bench. This will not only help the developers to simplify the testing process but will also help them to integrate several other features for improving the efficiency of Cypress testing.

For instance, cloud platforms allow developers to perform test cases on hundreds of real devices present on multiple cloud servers. Thus, integrating a cloud platform will eliminate the hassle of maintaining a physical device testing bench. By only paying a minimum license fee, the developers can execute hundreds of test cases on these devices from anywhere in the world.
