Types Of Software Testing - Why Is Testing Necessary?

Normally, we do not think about how much effort developers ought to put into providing customers with a high-high quality product. Programmers aren't the only individuals who take part in 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, fundamental testing? Let's consider this difficulty!

Common software testing types

When you order a new website or mobile app from a software development company, for example, testing companies 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 permits testers to grasp what the app should do and the right way to keep away from bugs.

Then QA engineers start making use of varied types of testing to particular software. These types embody the next:

Acceptance testing. Testers verify 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 can be accepted.

Smoke testing. It's 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 is launched.

Regression testing. It is applicable if during the development process some modifications in source code are made. But when we want particular functionality to work properly, the operation might not work after sure changes. So regression testing allows specialists to seek out 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 perform or one other is working in line with necessities said within the specification. It's a subset of regression testing.

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

Permission testing. That's where QA engineers should check how the permission system is functioning within the software that is being tested. For example, you're an peculiar user, and it could have been very strange when you had access to the administrator's access rights, would not it? And testers want to guantee that everything is working properly.

Usability testing. QA engineers must perceive how to make the final product person-friendly. So that they put themselves within the shoes of common customers - they need to test the software's usability, and find out whether it is simple-to-use or not.

Advanced testing types - why are they needed?

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

Dash 0 activity. It signifies that QA specialists begin testing even earlier than the software is finished. It makes it doable to keep away from bugs at an early stage.

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

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

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

Load testing. What will happen to your app if too many users begin using it simultaneously? That is what testers should discover out after which create the maximal load for the software.
