Why is testing necessary? What kind of tests do you need? Features of manual and automatic testing.
Testing as a mandatory step in software development
Today on the market, many monotonous applications and programs need to perform their essential functions. It is mainly because the developers needed to conduct comprehensive testing, which was supposed to reveal possible errors. At seclgroup.com, you will find a company of developers who don’t make such ridiculous mistakes and know that it’s only possible to create outstanding software with testing.
Why is testing mandatory?
You may have encountered poor-quality software that does not perform essential functions. Testing is necessary if you want your product to be convenient and valuable.
Many compare the work of a tester and an editor. No matter how good the author is, he can make mistakes like the most experienced programmer. An outsider’s view can reveal many more errors than someone working on software for a single day.
If you want to develop quality software, you need to conduct comprehensive testing, which will help you identify the minor bugs that can negatively affect the quality of the software.
Types of testing
Today, there are 2 main types of testing – automatic and manual. Each has its advantages and disadvantages, so it is worth discussing them in more detail.
Manual testing is when a specialist begins to proofread the program code and check the quality of the interface. Usually, this testing takes a lot of time, but it is cheaper.
It is usually used when you check the quality of the user interface and navigation. Thanks to this testing, you can check how comfortable your users are using your product and how useful it can be.
Since manual testing costs less than automatic testing, it is often used for projects with a limited budget, for example, small startups, where the quality of service and user interface are essential.
It will also be good to involve several people who can become potential clients to check your interface. Based on the feedback received, you will be able to understand how best to improve your product.
It involves using various tools to find the slightest errors and vulnerabilities in the software. It is worth saying that this type of testing can make testing more qualitative since it covers many times more code and it can reveal errors that are not available during manual testing.
For example, thanks to automated tests, you can easily simulate a situation where a large number of users (several hundred) are using your site simultaneously, which allows you to understand how it reacts to a large load.
Among the main advantages of automated testing are the following:
- Deeper code analysis;
- High speed;
- Easier to make a report;
- No errors due to human error.
Since various tools carry out testing, you can minimize problems due to the human factor.
Automated testing suits all projects (multifunctional websites, mobile applications). It is ideal for testing functionality, security, cross-platform, and many other metrics. However, it cannot simulate human behavior, so interface testing is best done with manual tests.
It is worth saying that automated testing has been developing rapidly in the last few years. Many experts say that this may replace manual tests shortly. However, we do not recommend neglecting these two types of testing at this stage. Otherwise, you risk getting a poor-quality interface or poor functionality.
When is the best time to test?
Many believe testing is necessary before a product is released to the market. But, you can achieve the best results if you perform tests at all stages of software development.
When planning a product, you need to consider what tools you will use for software development and testing. The sooner you start strategizing, the better.
Several specialists are working on creating software, each person responsible for their stage. After completing each module, you must carefully check it for errors. Otherwise, the slightest mistakes at this stage can lead to more difficult mistakes in the future.
After all the modules are ready, they must be created into one software. It is usually where the most errors occur, as some modules may not be compatible with each other or may not work at all. At this stage, you need to conduct the most in-depth analysis of your software.
When the testers start work, they systematize the received data, discuss errors, and advise on eliminating them. After that, programmers must make changes. If they have questions, they can contact the testers.
After programmers make changes to the program code, it is necessary to perform testing again to make sure that the corrections were made correctly and did not lead to new errors.
You’re mistaken if you think this is the end of testing. After you release the software, you need to run tests regularly. To keep your software competitive, you must constantly scale it up and add new features. In addition, when your business starts to grow, the load on the software increases. If you want it to be able to serve a large number of users simultaneously, you need to load it from time to time.
Testing is one of the most critical steps in creating software development. It allows you to identify bugs that may cause your product not to perform its primary functions or users may be dissatisfied with the service. If you can do it well, you can be sure that all the previous steps are worthwhile and that users will like your product.
