Testing is essential while creating applications. It makes sure that the code functions as planned and aids in finding any flaws or problems before they are released for use. It is a complex process, though. Writing effective tests is the first step in creating an efficient automation testing process, but even experienced developers can make mistakes that result in ineffective or inefficient tests.
combination makes perfect sense and is appropriate for automation testing
By avoiding the below-mentioned typical errors, developers can maintain the code functioning as intended. Thus, they can ensure the tests are efficient and effective and find problems before they are used in production.
Mistakes based on Syntax
Writing Assertions inside the Page Objects
Therefore, instead of using highly nested layers of abstraction, keep the assertions outside of the page objects and mainly in the Test files or Test helpers. This makes it easier to reuse the same function to check various results by treating the page object as an abstraction for a certain page or component.
Not doing a cross-browser compatibility check
Using the Return Statement incorrectly
Using Undefined/Null Keywords Inadequately
When developing websites and web apps, many developers are unaware of how to use undefined and null keywords.
Changing selectors location
As developers move the selectors on a responsive website's web page, the size of the resulting web page changes. As a result, test cases that depend on the size of the web page fail. To fix such failure developers can use a selector that does not change when the size changes. For example, they can consider utilizing unique names or user interface identifiers as selectors.
Use Page Object Model (POM)
Use PageObjects to improve overall maintenance and lessen duplication and redundancy. A Page Class is constructed for each web page, and the various elements are defined as variables, with methods used to implement user interaction.
The benefits of employing the Page Object Model include less maintenance work, less duplication of code, and improved script readability and dependability.
Use the Right Locators
The correct locators must be used to improve object navigation within the DOM as the Selenium framework is designed to communicate with browsers (Document Object Model).
Perform Data-Driven Testing
To complete functional testing more quickly and for reliable results, ensure the testing is data-driven.
Running parallel tests
Several tests can be executed simultaneously in various situations because of parallel testing. This directly leads to faster execution, shorter execution times, and earlier issue detection. Parallel testing is supported by Selenium Grid.
Create a CI/CD pipeline
The practice of CI/CD is receiving a lot of attention in the context of application development supported by Agile and DevOps.
Many CI/CD tools are available, including Jenkins, Bamboo, GitLab, etc. Creating a CI/CD pipeline for Selenium web automation enables early bug identification through rapid execution and consistent results, and also provides enough space for parallel testing capability, and increased scalability.
Test across browsers to increase test coverage
Make sure the application functions as expected across various browser versions, platforms, and devices to stay competitive in the market and win over users.
Using a cloud-based platform like LambdaTest requires no setup, deployment, maintenance, or scaling up of internal infrastructure, thus it includes low investment costs. This platform gives users access to hundreds of browser and platform combinations and expands its support for old and outdated ones.
