Selenium Automated Testing: Key Tips to Improve Results

In the software development process, automated testing is an important tool to improve efficiency and quality. And Selenium, as a widely used automation testing tool, provides developers with powerful features and flexibility.

What is Selenium?

Selenium is a set of tools and libraries for automating browser actions used to automate tests executed on web browsers. It supports multiple programming languages (e.g. Java, Python, C#, etc.) and allows developers to write scripts to simulate user actions on web pages such as clicking, typing, submitting forms, etc. It can also be used to fetch information. Selenium can be run in different browsers such as Chrome, Firefox, Safari, etc., and is therefore suitable for cross-browser automated testing.

What are the Strengths of Selenium?

1. Multi-language: Test scripts can be written in multiple programming languages: Java, Python, C#, PHP, Ruby, Perl, and .Net

2. Multi-System: Tests can be executed on any of the following operating systems: Windows, Mac, or Linux.

3. Multi-browser: Tests can be run using any browser: Mozilla Firefox, Internet Explorer, Google Chrome, Safari, Opera, Edge, etc.

4. Low cost: Selenium is an open-source tool, so there are no license costs involved, which is a major advantage over other testing tools.

5. Can be integrated with a variety of other tools to achieve continuous testing and report generation

How to Improve Selenium Automation Testing?

1. Explicit wait:

In automated tests, the time between page loading and element appearance may vary. To solve this problem, you can use the explicit wait mechanism provided by Selenium. An explicit wait waits for a certain time before a specific condition is met, such as waiting for an element to be visible, clickable, or present. This ensures that scripts are executed at the right time, avoiding unnecessary timeouts and errors.

2. Data-driven testing:

By separating the test data from the code and using a data-driven testing framework such as TestNG or JUnit, you can easily manage test data and parameterize test cases, reduce code redundancy, and achieve better test coverage.

3. Parallel testing:

Parallel testing is a way to improve testing efficiency by running multiple test cases at the same time. Selenium supports parallel testing by running tests on multiple browser instances or multiple nodes at the same time. By using a distributed testing framework, such as Selenium Grid or WebDriverManager, cross-browser and parallel testing can be realized, saving testing time and improving test coverage and stability.

However, in some cases, some websites may block Selenium-initiated requests, preventing the execution of automation scripts.

How to solve this problem? We can use the VMLogin fingerprint browser, VMLogin supports diversified browser automation, such as Selenium, Puppeteer, etc., and more than a variety of API interfaces to provide, any repetitive tasks can be executed in VMLogin to obtain data information; and VMLogin allows Selenium to bypass the detection of the site, the Let the automation script will not be prevented from running, to ensure that the automation test is carried out normally, which is a key point to improve the effect of automation testing.

In addition, VMLogin can also be used for self-testing. See how your site performs with various traffic analysis and filtering system settings by running tests in a LIVE environment. Find out how your website content is performing based on the specifics of your visitors.

4. Logging and reporting:

Using a logging framework, such as Log4j or SLF4J, you can record critical execution information and error logs. In addition, using a test report generation tool, such as Extent Report or TestNG Report, you can generate easy-to-read and understand test reports that facilitate sharing and analyzing test results with your team. Selenium is a powerful automated testing tool that can help developers improve testing efficiency and quality. By exploring and learning in practice and applying Selenium to real projects, you will be able to enjoy the many benefits of automated testing.
