The primary motive of the application testing process is to ensure the stability of the apps while revealing the bugs and errors that might be present in the core framework. The functionality of application testing is further enriched with the integration of Selenium automation testing. This is because, with this advanced process, the developers can run multiple instances simultaneously. Test automation also allows the integration of modern technologies like Agile Methodologies to run the development and testing processes side by side. While implementing these processes, the app testers can deploy various 3rd party plugins to further improve the accuracy of the reports.
Through this article, we will discuss the process of integrating Lighthouse Performance metrics while using an online Selenium grid for automation testing. We will also discuss how the app developers can access these data during the test analysis process. Finally, we will understand some of the integrations that can help simplify the entire process.
Before we move on to Selenium, let us understand the basic functioning and intention of automation testing. Firstly, it is an effort towards the removal of human involvement in the test case execution process. Instead, the system will use a series of predetermined parameters, supplied by test data to identify the functioning and stability of the apps. This is because using these parameters, the system can emulate human interactions while communicating with the app. It is also possible to make notable changes in the test data to customize the reports according to the project requirements.
In the modern app development market, the primary upsides of integrating test automation are mentioned below:
Now coming to Selenium, we can say that it is an umbrella project consisting of different tools for initiating automation testing on web-based apps. All of these tools are unique and have a definite role in the test case execution process. The core infrastructure of Selenium works on the popular programming language, JavaScript. While using Selenium, app developers can access its features without any license charges due to the open-source infrastructure.
In the modern app testing process, the Selenium tools will assist the application testers in the following stages:
We would like to caution the app developers that Selenium is only useful when they are working with web apps. For other alternatives like native apps, cross-platform apps, and hybrid apps, they need to look for an alternative in the market.
From the point of Selenium automation testing, LambdaTest can be highly useful as it provides the cloud best environment for initiating the test cases on real devices. Using this platform, the app developers can run the Selenium test cases on thousands of different browsers, operating systems, and real devices. The integration of all these test reports also helps the app developers to massively boost the accuracy of the test reports.
The LambdaTest Real Device Testing Cloud can help with Selenium automation testing in the following ways:
The lighthouse performance metrics allow the application developers to view scores including accessibility, portability, best practices, and the progressive nature of the web application. With the integration of LambdaTest, the app developer can easily integrate a lighthouse performance metric and access the data during the Selenium testing process.
To simplify this process for the new automation testers and developers, we have mentioned the prerequisites and intended steps below:
DesiredCapabilities caps = new DesiredCapabilities();
.
.
// To view performance metrics
caps.setCapability(“performance”, true);
Now, let us look at a code snippet that will allow the app developers to trigger the lighthouse performance metrics on LambdaTest during the test case execution process:
DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability(“browser”, “Chrome”);
caps.setCapability(“version”, “86”);
caps.setCapability(“platform”, “macOS Catalina”);
caps.setCapability(“build”, “Lighthouse Performance Demo”);
caps.setCapability(“name”, “TestNG Test 3”);
caps.setCapability(“network”, true);
caps.setCapability(“visual”, true);
caps.setCapability(“video”, true);
caps.setCapability(“console”, true);
caps.setCapability(“selenium_version”, “4”);
// To view performance metrics
caps.setCapability(“performance”, true);
To access the data from lighthouse performance metrics, the app developer simply has to follow the mentioned steps:
A very useful tip for app developers is to remember that the test duration must be 30 seconds or more to generate the lighthouse performance report.
The official website will also provide adequate information about some of the common issues that can arise during the Selenium automation testing process with LambdaTest. It will also provide some of the common solutions that can help resolve these issues.
The Final Verdict
So we discussed the importance of integrating lighthouse performance metrics with Selenium automation testing. The integration of LambdaTest further simplifies this process with its cloud infrastructure. It is also essential for the developers to have a different idea about modern automation testing practices. Some of the common tips involve constantly gaining information about the new trends and innovations in the segment of test automation. Finally, market surveys can help develop a customized application based on the target audience’s requirements. These are some of the most essential tips that can help app development companies boost their productivity and increase their audience reach.
