Salesforce is one of the leading cloud-based CRM used by major companies and brands like Coca-Cola, FCA, GE, Philips, and several others.
It is a widely used CRM application. Quality is an essential part of any of its minor/major releases. Automation testing is the highest-demand and active way of testing, which can make your life your life easier by considering repetitive and monotonous test cases, as well as the pyramid test levels that are impossible to cover manually.
It is possible to reduce the number of defects by writing the unit test case in an app under the criteria of 75%-90% coverage, but it may result in only your APEX custom or code objects that are under testing.
It is not sufficient to push your app over the app exchange. Instead, it needs to have an automated way to check your Salesforce app from integrated testing perspective using the standard as well as custom implementations.
Selenium being a reliable testing framework for web applications provide a playback tool or record for test authoring without any test scripting language knowledge, i.e., Selenium IDE.
It enables the test domain-oriented language – Selenese  to write test in numerous programming languages such as C#, Java, Perl, PHP, Ruby, and Python.
These tests can run against modern web browsers like Chrome, Firefox, and Internet Explorer. Selenium can deploy on Linux, Windows, and Macintosh platforms.
Selenium can leverage in automation testing to move some manual changes between Salesforce organizations from one to another. It avoids preparing test day each time whenever sandbox is refreshed and so on with endless usability.
Most testers would agree that the test steps, test data, and prerequisites are significant components of test cases. Most of the stakeholders ask that “Why shouldn’t use Selenium along to Test?” As UI test cases can stimulate user actions like selecting menus, clicking buttons, or validating text on a web page, you should test these actions to make sure the application quality as an end user. However, the problem with these Selenium test cases is that they are flaky and with a slow approach.
Having said that, if there exists a test case name H that needs a test data opportunity and other 50-60 such test cases that perfectly fits this criterion, then there is no need to create test cases in that vast numbers.
You can create an opportunity for one case through UI, and then send a “Create Opportunity” request to Salesforce for the remaining. Leveraging APIs also helps users to fetch data from Salesforce as it doesn’t have an exposed database, to carry data using SOQL, rely on this API framework.
It is a known fact that Salesforce’s objects are not allowed to access with valid credentials. Proper access token integration is essential to authenticate. You can generate a user access token through a sequence:
Logging in → Settings→ Request Security Token
It will send a request for the access token to the registered email address. Don’t forget that this token can be reset once to change your username/password.

Some of the API testing frameworks can be used in this process including rest assured. These will provide you with the convenience of creating requests in the when (). Given (). Then (). Format, which improves maintainability and saves you effort.
An open-source Selenium project can widely use for all browser-based UI testing that stimulates end user’s actions, and Salesforce leverages to automate test case over 40,000.
