7 Types of Essential Testing | Testworthy

The development team made software that is ready to be deployed. Right? No, it is wrong! You’ve got to get it tested first!

Every software made is run through a series of tests before deployment to ensure that the software is free from any bugs and performs well. Functional testing checks the app's performance, whereas non-functional testing mainly focuses on the overall user experience by inspecting the responsiveness and usability of the application.

For instance, the function of a simple notepad application is to jot down the brilliant ideas or thoughts that pop into our minds at any instance. We expect the app to have a writing option, a hand-drawing option, and the ability to highlight and underline text. These are functional aspects. If we look at the placement of the highlight button, the level of customization etc. all these interfaces and navigational things are part of the non-functional aspect.

Several test cases (user scenarios) run through the code. The errors observed are then corrected to ensure that a seamless and bug-free application reaches the users. Here the question arises, who conducts all of these tests? Who is responsible for uncovering and correcting the bugs? The answer depends on whether the testing is manual or automated. The difference is simple, a human! In manual testing, there is human interaction where a tester observes the behavior of the application by using it. Whereas in automated testing, a test management tool runs the test cases and generates a good bug report of the whole process, leaving no spots unchecked.

Here are some of the basic types of testing that can be done:

The Functional tests


  • • Unit testing: This is one of the first tests in the testing phase. The reason is that it checks the working of every component, ensuring that it is working so that in later stages, the bugs are easy to track and fix. There are three parts in unit testing: the input-output, functional behavior, and the execution of test cases which are checked through black box, white box, and grey box testing techniques respectively. Whether the testing is automated or manual, the process is the same: write and run test cases, locate the bugs and fix them. This daunting task can be very well-handled by a test management tool like Testworthy that not only manages the test cases, but also generates a comprehensive report to provide insights into the results.

  • • Integration Testing: Once the individual components are checked, it's time to see if they are working well together. For this, testers use either a big bang approach, where the system is run at once and checked for bugs, or an incremental approach that checks the code in parts. Furthermore, having a design document, a test management tool, and a test plan makes the whole process effortless.

  • • Smoke Testing: These tests, conducted by the QA team, are all about the working and stability of the application. If a bug is found during these tests, the application is sent back to the developers to get it fixed. It is primarily a quality test of the software. After the QA team is done testing, the software test engineer further conducts functionality testing. These contain test cases that check the data libraries, and modules for the quality of the build of the software. It ensures that the software is completely developed, before further testing, avoiding any wastage of test resources and time.


The Non-Functional tests


  • • Performance: For this testing, multiple kinds of test cases test the response time and accuracy of the software. It focuses on the stress the application can handle given the workload and the volumes of data it gets.

  • • Usability Testing:How can I say it is a good application when I cannot use it? This test is all about how well the application interface guides the user towards different functions of the application. Here, a group of users is observed to see how quickly they completed a set of tasks which determines the design's ease of use.

  • • Compatibility Testing: There is this new application that I want to use, but I cannot use it on my laptop. Why? Because it's not compatible! Now you know why compatibility tests are important. To ensure that the application can work on various operating systems, devices, and networks.

  • • Security Testing: When you save your data on a drive, you know it will be safe as no one can view it, delete it or edit it. To ensure this, the developers build a security web with a network of codes. Security testing is there to test the security against hackers and any other vulnerabilities.

To conclude, testing checks for bugs and errors in applications, to ensure a reliable, accurate, and smooth user experience. For this, the types of testing involve manual or automated, with functional and non-functional types. Since testing is a crucial part of software development, a test management tool will ensure error-free testing, making the application more reliable.
