Usually, we don't think about how a lot effort developers should put into providing customers with a high-quality product. Programmers usually are not the only people who participate within the software development. For proper functioning, the program must 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 problem!

Frequent software testing types

When you order a new website or mobile app from a software development company, for example, testing services are included in the development process by default. But how does it happen? As a rule, the first QA engineers perform a Requirement analysis. It allows testers to grasp what the app ought to do and how one can avoid bugs.

Then QA engineers begin making use of numerous types of testing to specific software. These types embrace the next:

Acceptance testing. Testers confirm whether software meets all acceptance criteria. Then it's as much as the client to decide whether or not the software will probably be despatched for revision or shall be accepted.

Smoke testing. It's much like acceptance testing. At this stage, QA engineers make a brief 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 particular functionality to work properly, the operation may not work after certain changes. So regression testing permits specialists to find out whether or not required functionality works properly and as well because it used to.

Sanity testing. It's a centered testing oriented for affirmation that one function or one other is working in line with necessities said within 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 is made in a single style. It implies testing with completely different screen resolutions, compatibility with numerous Internet browsers, as well because the testing of localized versions - 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 in the software that's being tested. For example, you are an abnormal user, and it might have been very strange if you happen to had access to the administrator's access rights, would not it? And testers want to ensure that everything is working properly.

Usability testing. QA engineers must perceive easy methods to make the ultimate product person-friendly. So they put themselves in the sneakers of widespread customers - they need to test the software's usability, and discover out if it is simple-to-use or not.

Advanced testing types - why are they necessary?

In most cases, all testing types considered above can assist specialists to make good testing. But if your product is non-standard, the need in advanced testing may arise. Advanced testing includes the next:

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

Automated Functional and Regression testing. Automation makes it doable to get fast results and to fix all bugs as soon as possible. Also, this testing type means that you can launch the test with numerous parameters: a number of variations of enter and expected data.

Compatibility testing. It is very important understand how the product is suitable 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 occur to your app if too many customers start utilizing it concurrently? That is what testers should find out and then create the maximal load for the software.
