Types Of Software Testing - Why Is Testing Necessary?

Often, we do not think about how a lot effort developers ought to put into providing users with a high-high quality product. Programmers are not the only individuals who participate in the software development. For correct functioning, the program should 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 challenge!

Common software testing types

In case you order a new website or mobile app from a software development company, for example, testing companies are included within the development process by default. But how does it occur? As a rule, the primary QA engineers carry out a Requirement analysis. It permits testers to know what the app ought to do and the right way to avoid bugs.

Then QA engineers begin making use of varied 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 as much as the client to make a decision whether the software will be despatched for revision or will probably be accepted.

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

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

Sanity testing. It is a focused testing oriented for confirmation that one perform or one other is working based on requirements acknowledged in the specification. It's a subset of regression testing.

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

Permission testing. That is where QA engineers should check how the permission system is functioning in the software that's being tested. For instance, you are an abnormal consumer, and it will have been very strange in case you had access to the administrator's access rights, wouldn't it? And testers want to make sure that everything is working properly.

Usability testing. QA engineers must perceive the best way to make the ultimate product person-friendly. In order that they put themselves within the footwear of widespread customers - they need to test the software's usability, and discover out whether it is simple-to-use or not.

Advanced testing types - why are they obligatory?

In most cases, all testing types considered above might help specialists to make good testing. But if your product is non-customary, the necessity in advanced testing might arise. Advanced testing contains the following:

Sprint zero activity. It means that QA specialists begin testing even earlier than the software is finished. It makes it attainable 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 anticipated data.

Compatibility testing. It is important to understand how the product is appropriate with system parts and different apps.

Interrupt testing. Everything is easy 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 users begin using it simultaneously? That is what testers should find out and then create the maximal load for the software.
