Every software development firm conducts a test in the current digital world before introducing the software, yet we can always see the defects. The developers try to catch the bug before the release, but it will get rectified in the post-release phase in most cases. These kinds of situations are expected if a developer tries to conduct the testing manually. Hence, automating the test is an essential thing for the success of every application and software. When it comes to automating the test case, there is no better option than Selenium for the developers and testers. It offers a variety of advantages to combat all kinds of hindrances. However, the testing process becomes more reliable and effortless if combined with the right programming languages. Even though selenium supports many programming languages, Java is the best option for developers. Thus, without a doubt, we can tell to improve the selenium performance, Java is the best option.
Why do developers and testers prefer Java with Selenium?
The strong community support with numerous developers helped Java to become one of the most preferred programming languages. So, using Selenium with Java provides innumerable benefits. This is why Selenium Java training is getting more fame these days than any other programming language for Selenium testing.
- Selenium is a language-independent platform; hence it supports many languages, including Java. As a result, developers can leverage the massive active community support to write test cases with detailed documentation.
- Java makes programs work faster than other programming languages. It works even more quickly than Python.
- In commercial applications, the usage of Java is more than Python and other leading programming languages. Approx. 77% of developers prefer and use Java compared to other languages. This is because the integration of Java with Selenium is more straightforward and makes the testing smooth.
Best practices to improve Selenium performance with Java.
Selection of right locator
Using the right locator is a critical part of the automation with selenium since they are the building blocks of testing scripts. If the developers use incorrect locators, it makes the script unreliable and flaky. The locators such as “Name” and “ID” are comfortable, and they offer a faster execution than XPath and CSS.
Usage of data-driven scripts
The testing always involves testing on numerous permutations and combinations of data. And the same principle applies to Selenium with Java. Several data points must drive all selenium tests with the help of a data-driven framework. This is one reason why many experts say learn Selenium WebDriver to know all the possibilities of Selenium.
using the right ‘wait.’
It is vital for page load and web elements to provide a specific halt time to your scripts to avoid the script’s failure. The ‘implicit’ and ‘explicit’ types of waits available in Selenium help to achieve this. These waits stop the execution of the script until it locates the element. Once it finds the element, it continues the execution of your scripts. Thread.Sleep halts the execution for a specifically defined period, even if it encounters elements.
Avoid making the scripts for a specific driver or browser.
The running of the test scripts depends on the business-specific goals. It may be expected to run on various browsers, and sometimes it should run on a specific browser. Whatever the need of your clients or business, the cross-browser testing capabilities are vital. The TestNG framework available in Selenium provides annotations like @parameters, and JUnit offers annotations such as @RunWith that assists in running tests on various drivers and browsers. You can get to know more about these annotations and other vital details if you opt for the best Selenium online training.
Taking reports and screenshots
For a QA tester, to give proof of testing the failure and successful run is vital. Hence, capturing supportive screenshots is essential. Even for automated testing with Selenium, it is necessary. Especially if any test cases become a failure, taking the screenshots helps to understand the error types to the developers, and they can instantly catch hold of the thing causing those bugs. Even it is essential to provide insights to the stakeholders, and also it is mandatory in many organizations since it is subjected to detailed auditing.
