What is Functional Testing?

Types of Functional Testing

Unit Testing

Smoke Testing

Regression Testing

Sanity Testing

Integration Testing

System testing

Cross Browser Testing

Advantages Of Automated Functional Testing

  • Enable the delivery of a high-quality product that meets end-users requirements while ensuring that they are satisfied with the end results.
  • Produces a bug-free software product while ensuring that all the functionalities of the application are working properly.
  • Improves the overall security and safety of the application.
  • Reduces the risks and losses associated with the web app/software product.

Steps Involved in Automated Functional Testing

  • Determining the functional components of the web app that needs to be tested, which includes basic usability, accessibility, main functions of the application, and error conditions.
  • Creating the input data for functionality testing after determining the main components of testing.
  • Determining the expected outcome for the functionality based on the input data.
  • Executing test cases that are created for functional testing.
  • And the last step involves comparing the output results with the expected results, and if the outcome is similar to expected results, then your functional testing is successful.

Techniques for Functional Testing

  1. Positive Testing — This type of testing ensures that the product meets the basics requirements of users and work efficiently as expected. It can be divided into three subcategories, which include:
  • End-user based tests
  • Decision-based tests
  • Alternate path tests
  • Equivalence tests
  • Boundary value tests
  • Ad-hoc tests

Functional vs Non-functional Testing

Best Automated Functional Testing Tools

  • LambdaTest — It is an incredible cloud-based Selenium Grid that can help you perform automated functional testing of your web app across multiple platforms. Besides, it provides you with numerous features like Screenshot, Video Recording, Live Interactive Testing, etc.
  • Ranorex Studio — It is an all-in-one automated functional testing tool for desktop, web, and mobile apps with in-built selenium WebDriver.
  • Selenium — If you’re looking for an open-source automation tool, then Selenium is the way to go. If you’re wondering, what is Selenium, you can refer to our detailed page on it.
  • JUnit — Businesses who need to test the functionality of their Java applications can opt for JUnit, which is designed explicitly for Unit and System testing of Java applications.
  • SoapUI — It is another open-source functional testing tool that is widely used for web service testing. Also, it supports various protocols like HTTP, SOAP, and JDBC.

Automated Functional Testing Using Selenium

  1. Creating a WebDriver test case
  2. Go to the specific web page for testing
  3. Find the HTML element for testing on the web page
  4. Execute an action on the HTML instance
  5. Await for browser response to the action
  6. Running tests and recording the output with a test framework
  7. Concluding the test.
