Types Of Software Testing - Why Is Testing Important?

Usually, we don't think about how a lot effort builders should put into providing users with a high-high quality product. Programmers usually are not the only people who participate in the software development. For correct functioning, the program have to be tested. And this job falls on the shoulders of QA engineers. What strategies do they use for good, proper, primary testing? Let's consider this difficulty!

Common software testing types

For those who order a new website or mobile app from a software development firm, for instance, testing providers are included in the development process by default. But how does it occur? As a rule, the first QA engineers carry out a Requirement analysis. It allows testers to understand what the app ought to do and find out how to keep away from bugs.

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

Acceptance testing. Testers confirm whether software meets all acceptance criteria. Then it is up to the shopper to decide whether or not the software might be sent for revision or shall be accepted.

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

Regression testing. It is applicable if throughout the development process some changes in source code are made. But when we'd like specific functionality to work properly, the operation might not work after sure changes. So regression testing permits specialists to seek out out whether required functionality works properly and as well as it used to.

Sanity testing. It's a focused testing oriented for affirmation that one perform or one other is working in accordance with necessities acknowledged in the specification. It is a subset of regression testing.

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

Permission testing. That's where QA engineers ought to check how the permission system is functioning in the software that is being tested. For example, you're an unusual user, and it could have been very strange in case you had access to the administrator's access rights, would not it? And testers need to be sure that everything is working properly.

Usability testing. QA engineers must understand how one can make the ultimate product user-friendly. So that they put themselves in the sneakers of widespread users - they should test the software's usability, and discover out if it is easy-to-use or not.

Advanced testing types - why are they needed?

In most cases, all testing types considered above may help specialists to make good testing. But if your product is non-normal, the need in advanced testing may arise. Advanced testing consists of the following:

Sprint 0 activity. It implies that QA specialists begin testing even before 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 potential to get fast results and to fix all bugs as soon as possible. Additionally, this testing type allows you to launch the test with various parameters: a few versions of input and expected data.

Compatibility testing. You will need to understand how the product is suitable with system components and other apps.

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

Load testing. What will happen to your app if too many users start using it simultaneously? That is what testers must find out after which create the maximal load for the software.
