Normally, we don't think about how a lot effort builders should put into providing users with a high-quality product. Programmers will not be the only individuals 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 methods do they use for good, proper, fundamental testing? Let's consider this problem!
Frequent software testing types
In case you order a new website or mobile app from a software development company, for instance, testing companies are included in the development process by default. However how does it happen? As a rule, the primary QA engineers carry out a Requirement analysis. It permits testers to grasp what the app ought to do and find out how to avoid bugs.
Then QA engineers begin applying various types of testing to particular software. These types embrace the following:
Acceptance testing. Testers verify whether or not software meets all acceptance criteria. Then it is as much as the client to decide whether or not the software will probably be sent for revision or will 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 features, how it works, and the way it's launched.
Regression testing. It is applicable if through the development process some modifications in source code are made. But when we need particular 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 as it used to.
Sanity testing. It's a targeted testing oriented for affirmation that one function or one other is working based on necessities acknowledged within the specification. It's a subset of regression testing.
UI testing. The tester verifies whether the software meets requirements of graphic person 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 versions - 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 is being tested. For instance, you're an bizarre person, and it will have been very strange should 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 should understand methods to make the ultimate product consumer-friendly. So they put themselves within the sneakers of common users - 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 essential?
In most cases, all testing types considered above might help specialists to make good testing. But when your product is non-customary, the need in advanced testing might arise. Advanced testing includes the next:
Dash 0 activity. It implies that QA specialists start testing even before the software is finished. It makes it attainable 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. Additionally, this testing type allows you to launch the test with various parameters: just a few variations of input and expected data.
Compatibility testing. You will need to understand how the product is compatible with system components and different apps.
Interrupt testing. Everything is straightforward right here - an understanding of how the product will work after an unexpected interruption.
Load testing. What's going to occur to your app if too many users begin utilizing it concurrently? That's what testers must discover out and then create the maximal load for the software.
