Types Of Software Testing - Why Is Testing Important?

Normally, we don't think about how a lot effort builders ought to put into providing users with a high-high quality product. Programmers are usually not the only individuals who participate in the software development. For proper 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, basic testing? Let's consider this concern!

Common software testing types

For those who order a new website or mobile app from a software development firm, for example, testing companies are included within the development process by default. However how does it occur? As a rule, the first QA engineers carry out a Requirement analysis. It allows testers to grasp what the app should do and the right way to avoid bugs.

Then QA engineers start applying 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 up to the customer to make a decision whether the software will be sent for revision or shall be accepted.

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

Regression testing. It's applicable if through the development process some adjustments in source code are made. But if we need particular functionality to work properly, the operation could not work after certain changes. So regression testing allows specialists to find out whether required functionality works properly and as well because it used to.

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

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

Permission testing. That is the place QA engineers ought to check how the permission system is functioning in the software that's being tested. For instance, you are an extraordinary user, and it might have been very strange in the event you had access to the administrator's access rights, would not it? And testers need to make sure that everything is working properly.

Usability testing. QA engineers should understand methods to make the ultimate product consumer-friendly. So they put themselves within the footwear of frequent users - they need to test the software's usability, and discover out if it is easy-to-use or not.

Advanced testing types - why are they necessary?

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

Dash 0 activity. It means 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 quick outcomes and to fix all bugs as quickly as possible. Additionally, this testing type allows you to launch the test with varied parameters: just a few variations of enter and anticipated data.

Compatibility testing. You will need to understand how the product is appropriate with system parts and other apps.

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

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