Testing is a crucial moment in the development of a policy document. It is essential because it allows you to ensure that your product works correctly and provides quality services. Particular attention should be paid to functional testing because it will enable you to understand whether your product can perform the tasks it was created for.
Behavior-Driven Development BDD test ensure software aligns with user expectations, transforming requirements into executable scenarios for robust, user-centric validation.
What is functional testing?
It is used to test the operation of the black box. The primary purpose is to understand how your software works and can perform functions that will be useful to potential users.
Thus, functional testing should answer the following questions:
- Do all functions work?
- How easy is it to access the features you need?
- How easy is it to use the features?
- What happens when errors occur?
What is the difference between functional and non-functional testing?
Many today need to understand the difference between functional and non-functional testing fully. In simple terms, functional testing answers what your software should do, and non-functional testing is how well the system works.
As already mentioned, functional testing checks the operation of the black box, and non-functional testing checks the white box.
Functional: basic types
Today there are several types of functional testing; among the most important are:
- Unit testing;
- Functions;
- Availability;
- Smoke testing;
- Integration testing.
You can use some types of testing. Usually, choose those varieties that are more important for your project, given the specification and business requirements. So, for example, an eCommerce platform must have working tools for paying for goods. Get more detailed info about functional testing on this link.
Non-functional: basic types
To better understand the main features of non-functional testing, it is worth mentioning the types of this:
- Performance testing;
- Stress Testing;
- Reliability;
- System readiness;
- Usability testing.
Thus, non-functional testing can check how many people can pay simultaneously and many other vital points.
There are types of testing, such as regression testing, which can be classified as both functional and non-functional, depending on the purpose for which you use it.
Some tips to make testing more efficient
Testing is a highly complex process; we want to give you some essential tips to get a good result.
Use Exploratory Testing
Typically, testers use precise instructions to catch bugs, but this strategy may only sometimes be the right one. Sometimes it is beneficial if a tester gets creative when doing performance testing metrics and performs spontaneous tests that can reveal vulnerabilities in places that are not obvious at first glance.
Try to automate most processes
Automated testing has come a long way in the last few years. Today, they cover the code very profoundly, allowing you to identify the slightest errors and speed up the process of testing as much as possible. In addition, this will enable you to minimize the risk of errors due to the human factor. So, a person sets the basic parameters for testing, and computer technology will do the rest.
Shortly, automated testing will be able to replace manual testing completely. But practice shows that it is still too early to think about it. Modern tools cannot fully simulate human behavior, so checking the interface and other parameters are best left to living people.
Test as early and often as possible
Testing usually starts early in the development of software. Usually, if you can’t spot bugs early on, they’ll gradually snowball, and fixing them will be very difficult, time-consuming, and expensive.
The sooner and more often you test, the better product you can get in the end. Many people think such tests are expensive, so they refuse to take them. However, practice shows that fixing many accumulated errors is much more costly.
Plan your work carefully
Typically, test planning occurs in the early stages of software development. At this stage, it is necessary to determine which tools and tests to use. The better you think through these moments, the better result you can get in the end.
It is crucial to follow the same goal. Your tests must be thoughtful and incremental, not chaotic.
Cooperate with a professional company
It is imperative that you only cooperate with a professional team. It will be good if not one but several specialists are involved in testing, increasing the speed and quality of the work.
You do not need to hire specialists in the state, and it is much more profitable to use outsourcing services. It will allow you to save a lot of money, complete all the work on time, and get high-quality services.
Functional testing can become an essential part of your job when building software. It will give you an idea of how effective your software is and whether it can be helpful for your business.
