Types Of Software Testing - Why Is Testing Important?

Normally, we do not think about how much effort developers ought to put into providing users with a high-quality product. Programmers are usually not the only individuals 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 methods do they use for good, proper, basic testing? Let's consider this challenge!

Common software testing types

If you order a new website or mobile app from a software development firm, for example, testing companies 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 permits testers to grasp what the app ought to do and how to avoid bugs.

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

Acceptance testing. Testers confirm whether or not software meets all acceptance criteria. Then it is up to the client to make a decision whether or not the software can 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 features, how it works, and how it is launched.

Regression testing. It's applicable if in the course of the development process some changes in source code are made. But when we'd like specific functionality to work properly, the operation may not work after certain changes. So regression testing allows specialists to search out out whether or not required functionality works properly and as well because it used to.

Sanity testing. It is a centered testing oriented for affirmation that one perform or one other is working in response to requirements said within the specification. It is a subset of regression testing.

UI testing. The tester verifies whether or not the software meets necessities of graphic consumer interface, and whether it is made in a single style. It implies testing with totally different screen resolutions, compatibility with various Internet browsers, as well as the testing of localized versions - translation accuracy and the name length 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 are an strange user, and it could have been very strange if you happen to had access to the administrator's access rights, wouldn't it? And testers need to ensure that everything is working properly.

Usability testing. QA engineers must understand the way to make the ultimate product person-friendly. So that they put themselves within the sneakers of common customers - they should test the software's usability, and find out if it is straightforward-to-use or not.

Advanced testing types - why are they necessary?

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

Sprint 0 activity. It signifies that QA specialists start testing even earlier than the software is finished. It makes it potential to avoid bugs at an early stage.

Automated Functional and Regression testing. Automation makes it attainable to get fast outcomes and to fix all bugs as soon as possible. Additionally, this testing type permits you to launch the test with numerous parameters: a few versions of input and anticipated data.

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

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

Load testing. What's going to happen to your app if too many customers start utilizing it concurrently? That is what testers must find out after which create the maximal load for the software.
