Selenium is a portable testing framework for web applications. Selenium provides a record/playback tool for authoring tests without learning a test scripting language (Perl, PHP, Java, etc.).
Selenium is also used in automation. Automation is the process of automating manual tasks. This means that instead of performing the task manually, the task is performed by a machine or software.
If you’re new to Selenium, you may be wondering why you should use it over other testing tools.
The answer is simple: Selenium is extremely versatile and can be used to test applications of all types, sizes and complexity. Plus, it’s free and open source!
You don’t have to be a java whiz to be a selenium automation expert.
You can learn it using flow concepts in webdriver, along with a strong understanding of processes and some hands-on experience on objects, states, and bare-bones programming.
For example, knowing how to select elements on a page and how to work with the browser’s console will make your life as a tester much easier.

1) Download the latest version of Selenium IDE from the Selenium website
2) Install the plugin in your browser
3) OpenSelenium IDE and click on the “Options” button
5) Click on the “OK” button
6) Record your test by clicking on the “Record” button
7) Play back your test by clicking on the “Playback” button
8) Save your test by clicking on the “File” menu and selecting “Save Test”.
which is why it is required when using this software testing tool.
One best practice is to make sure that you are using the latest version of Selenium WebDriver. This will ensure that you have access to the latest features and fixes.
1. Look for best locator strategy
When it comes to automation testing, one of the most important pieces is the locator strategy. The locator is what tells the test script where to find the element on the page that it needs to interact with.
There are a few different options when it comes to locators in Selenium. The most common are XPath, CSS selectors, and ID.
XPath is a language that is used for locating nodes in an XML document. It has a syntax that allows you to specify where an element is located by its position in relation to other elements.
For example, if you wanted to locate the “username” input field on a login page, you could use the following XPath: //input[@id=’username’]
are another option for locating elements on a web page.
2. Page Object Model
Page Object Model is a design pattern that can be used in selenium to make your tests more maintainable and easier to understand.
There are three main steps to using Page Object Model in selenium:
- Create a page object for each page you want to test. Each page object should represent a single page in your application and contain all the elements and functionality that you need to test for that page.
- Write your test cases using the page objects. This means that instead of interacting directly with the selenium webdriver, you will interact with the page objects.
- Maintain your page objects by keeping them up-to-date as your application changes.
3. Browser Compatibility Matrix
Make sure about all these points:
- In order to ensure that your selenium scripts will work with the correct browser versions, it is important to maintain a browser compatibility matrix.
- This matrix should list the browsers and versions that you have tested your scripts with, as well as the ones that are known to be incompatible.
- By keeping this information up-to-date, you can avoid potential issues when running your tests on different browsers.
- Additionally, if you find that a certain browser version is causing problems, you can quickly check the matrix to see if it is compatible.
- If you are having trouble maintaining a browser compatibility matrix, there are various tools and services that can help.
- These tools can automate the process of checking for updates and incompatibilities, making it easier to keep your testing environment up-to-date.
4. Creating test cases beforehand to plan for a task.
Before starting to code automated tests, it is important to create test cases. This will help plan for the task at hand and ensure that all aspects of the application are covered.
There are a few things to keep in mind when creating test cases. First, think about what you want to test and what you need to do to set up the test.
Next, consider what assertion you will make at the end of the test. Finally, decide how long the test should take to run.
Once you have created your test cases, you can start coding your automated tests in Selenium. Selenium is a powerful tool that can help you create comprehensive automated tests quickly and easily.
With Selenium, you can run your tests on multiple browsers, making it a great choice for cross-browser testing.
5. Test coverage
Test Coverage is a metric that tells us how much of the code is covered by tests. It is a measure of how complete our test suite is.
There are different types of test coverage, but in general, we can think of it as the percentage of the code that is executed when the tests are run.
For example, if our codebase has 1000 lines of code and our tests only cover 500 lines, then our test coverage would be 50%.
One way to increase test coverage is to add more test cases. Another way to increase test coverage is to use a tool that can automatically generate test cases for you.
is one such tool. It can be used to generate functional tests for web applications. Selenium can also be used to generate load tests and performance tests.
It is also important to use the Selenium IDE when developing your tests. This tool will allow you to record and playback your tests, which can be very useful when debugging issues.

Selenium IDE is a great tool for those starting out in automation testing and it requires very little programming knowledge.
