Types Of Software Testing - Why Is Testing Important?

Often, we do not think about how much effort developers should put into providing users with a high-high quality product. Programmers should not the only people who participate in the software development. For correct functioning, the program must be tested. And this job falls on the shoulders of QA engineers. What methods do they use for good, proper, fundamental testing? Let's consider this situation!

Widespread software testing types

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

Then QA engineers begin making use of various types of testing to specific software. These types embody the following:

Acceptance testing. Testers verify whether software meets all acceptance criteria. Then it's up to the client to decide whether or not the software will probably be sent for revision or can be accepted.

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

Regression testing. It is applicable if throughout the development process some modifications in supply code are made. But when we want specific functionality to work properly, the operation might not work after certain changes. So regression testing allows specialists to search out out whether required functionality works properly and as well because it used to.

Sanity testing. It is a targeted testing oriented for affirmation that one perform or one other is working in line with requirements stated in the specification. It's a subset of regression testing.

UI testing. The tester verifies whether or not the software meets requirements of graphic user interface, and whether or not it is made in a single style. It implies testing with different screen resolutions, compatibility with various 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 within the software that's being tested. For example, you are an unusual consumer, and it could have been very strange should you had access to the administrator's access rights, wouldn't it? And testers wish to make sure that everything is working properly.

Usability testing. QA engineers should perceive the best way to make the ultimate product user-friendly. So they put themselves in the sneakers of widespread customers - they need to test the software's usability, and find out if it is easy-to-use or not.

Advanced testing types - why are they crucial?

In most cases, all testing types considered above may also help specialists to make good testing. But when your product is non-normal, the need in advanced testing may arise. Advanced testing includes the next:

Sprint 0 activity. It implies 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 quick outcomes and to fix all bugs as quickly as possible. Additionally, this testing type means that you can launch the test with various parameters: a number of versions of enter and anticipated data.

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

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

Load testing. What will occur to your app if too many customers start using it simultaneously? That is what testers should discover out and then create the maximal load for the software.
