Types Of Software Testing - Why Is Testing Necessary?

Normally, we don't think about how much effort developers should put into providing users with a high-quality product. Programmers aren't the only individuals who take part 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, fundamental testing? Let's consider this situation!

Frequent software testing types

When you order a new website or mobile app from a software development company, for instance, testing services are included within the development process by default. But how does it occur? As a rule, the first QA engineers carry out a Requirement analysis. It permits testers to understand what the app should do and learn how to avoid bugs.

Then QA engineers start applying varied types of testing to specific software. These types embrace the following:

Acceptance testing. Testers confirm whether or not software meets all acceptance criteria. Then it's as much as the shopper to make a decision whether the software might be sent for revision or will likely be accepted.

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

Regression testing. It's applicable if during the development process some changes in supply code are made. But when we want particular functionality to work properly, the operation might not work after certain changes. So regression testing permits specialists to seek out out whether required functionality works properly and as well because it used to.

Sanity testing. It is a focused testing oriented for confirmation that one operate or another is working in accordance with requirements stated within the specification. It is a subset of regression testing.

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

Permission testing. That's the place QA engineers ought to check how the permission system is functioning within the software that is being tested. For instance, you are an ordinary person, and it would have been very strange if you happen to had access to the administrator's access rights, would not it? And testers wish to ensure that everything is working properly.

Usability testing. QA engineers should understand the way to make the ultimate product person-friendly. So they put themselves within the footwear of widespread users - they need to test the software's usability, and find out whether it is straightforward-to-use or not.

Advanced testing types - why are they crucial?

In most cases, all testing types considered above will help specialists to make good testing. But if your product is non-standard, the necessity in advanced testing could arise. Advanced testing consists of the next:

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

Automated Functional and Regression testing. Automation makes it potential to get quick outcomes and to fix all bugs as soon as possible. Additionally, this testing type lets you launch the test with numerous parameters: a couple of versions of enter and expected data.

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

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

Load testing. What's going to happen to your app if too many users start utilizing it simultaneously? That's what testers must find out and then create the maximal load for the software.
