Types Of Software Testing - Why Is Testing Necessary?

Normally, we don't think about how a lot effort developers should put into providing users with a high-quality product. Programmers are not the only individuals who participate within the software development. For proper functioning, the program should be tested. And this job falls on the shoulders of QA engineers. What strategies do they use for good, proper, basic testing? Let's consider this concern!

Common software testing types

Should you order a new website or mobile app from a software development firm, for example, testing services are included within the development process by default. But how does it happen? As a rule, the primary QA engineers perform a Requirement analysis. It allows testers to know what the app should do and how to keep away from bugs.

Then QA engineers start making use of numerous types of testing to specific software. These types embody the following:

Acceptance testing. Testers verify whether or not software meets all acceptance criteria. Then it is as much as the shopper to make a decision whether the software will probably be sent for revision or shall be accepted.

Smoke testing. It's just like acceptance testing. At this stage, QA engineers make a brief cycle of tests to check how the new product performs its functions, the way it works, and the way it's launched.

Regression testing. It's applicable if throughout the development process some changes in source code are made. But if we want particular functionality to work properly, the operation could not work after certain changes. So regression testing allows specialists to search out out whether required functionality works properly and as well as it used to.

Sanity testing. It's a targeted testing oriented for affirmation that one operate or one other is working in keeping with requirements stated in the specification. It's a subset of regression testing.

UI testing. The tester verifies whether the software meets requirements of graphic user interface, and whether or not it's made in a single style. It implies testing with different screen resolutions, compatibility with various Internet browsers, as well as the testing of localized versions - translation accuracy and the name size of interface elements.

Permission testing. That is the place QA engineers should check how the permission system is functioning in the software that's being tested. For example, you are an bizarre user, and it might have been very strange in case you had access to the administrator's access rights, would not it? And testers wish to guantee that everything is working properly.

Usability testing. QA engineers should perceive learn how to make the ultimate product user-friendly. So that they put themselves within the shoes of frequent customers - they need to test the software's usability, and discover out if it is straightforward-to-use or not.

Advanced testing types - why are they needed?

In most cases, all testing types considered above can assist specialists to make good testing. But when your product is non-commonplace, the need in advanced testing might arise. Advanced testing contains the following:

Sprint zero activity. It means that QA specialists start testing even earlier than the software is finished. It makes it attainable to keep away from bugs at an early stage.

Automated Functional and Regression testing. Automation makes it doable to get fast outcomes and to fix all bugs as quickly as possible. Also, this testing type permits you to launch the test with numerous parameters: just a few variations of input and expected data.

Compatibility testing. It is very important perceive how the product is suitable with system elements and different apps.

Interrupt testing. Everything is easy here - an understanding of how the product will work after an unexpected interruption.

Load testing. What will happen to your app if too many users begin using it simultaneously? That's what testers should find out and then create the maximal load for the software.
