Often, we don't think about how much effort developers should put into providing customers with a high-high quality product. Programmers should not the only individuals who take part within the software development. For proper functioning, the program have to be tested. And this job falls on the shoulders of QA engineers. What methods do they use for good, proper, basic testing? Let's consider this challenge!
Widespread software testing types
In the event you order a new website or mobile app from a software development company, for example, testing companies are included within the development process by default. However how does it happen? As a rule, the first QA engineers carry out a Requirement analysis. It allows testers to know what the app ought to do and how you can keep away from bugs.
Then QA engineers begin applying various types of testing to specific software. These types include the following:
Acceptance testing. Testers confirm whether or not software meets all acceptance criteria. Then it is up to the shopper to make a decision whether the software shall be sent for revision or might be accepted.
Smoke testing. It's similar to acceptance testing. At this stage, QA engineers make a short cycle of tests to check how the new product performs its functions, the way it works, and how it's launched.
Regression testing. It is applicable if in the course of the development process some adjustments in source code are made. But if we'd like specific functionality to work properly, the operation could not work after sure changes. So regression testing permits specialists to find out whether 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 another is working in accordance 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 it is 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's the place QA engineers should check how the permission system is functioning in the software that's being tested. For example, you are an bizarre consumer, and it could have been very strange in the event 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 must understand the best way to make the ultimate product person-friendly. So they put themselves in the footwear of frequent users - they should test the software's usability, and find out whether it is easy-to-use or not.
Advanced testing types - why are they necessary?
In most cases, all testing types considered above will help specialists to make good testing. But when your product is non-standard, the need in advanced testing may arise. Advanced testing contains the following:
Dash zero activity. It implies that QA specialists begin testing even earlier than 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 potential to get fast outcomes and to fix all bugs as soon as possible. Also, this testing type allows you to launch the test with varied parameters: a number of versions of enter and anticipated data.
Compatibility testing. You will need to perceive how the product is appropriate with system parts and other apps.
Interrupt testing. Everything is easy 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 users begin using it concurrently? That is what testers must discover out after which create the maximal load for the software.
