Do you need to test the program if everything is already working fine? Our answer is definitely yes. Many people mistakenly believe that application testing takes an unreasonable amount of time and resources. Let’s see why this is still necessary.
Program testing is the observation of software functionality in various artificially created situations. In this way, test teams check the performance of the program, its protection levels, the simplicity of use, and the intuitive interface.
Main tasks of software testing process:
- Identify errors and promptly eliminate them
- Check the conformity of the product with the declared requirements
- Assess the quality of the work of developers
- Get the information you need to make different decisions
All data obtained during software testing is essential when planning a subsequent application development strategy. Programmers are humans, not a machine, and it’s hard to write thousands of lines of code without making mistakes or typos.
The world’s largest Internet IT giants are looking for and hiring the most advanced programmers from all over the world. And even they sometimes make mistakes – we mean software vulnerabilities, leaks of users’ personal data, and other bugs in the system.
Therefore, checks and possible corrections should be taken as a mandatory and most common process in the IT industry.
If you are looking for effective ways to boost customer satisfaction, your need a quality assurance testing company. UnBugify is a quality assurance company providing targeted, human-powered quality testing services.
Let’s examine the main objections and difficulties that arise before or during the testing phase.
What exactly needs to be tested?
And what exactly to test? Ideally, everything. Testing will greatly facilitate your work on the project if it affects all its elements.
Analyze the cases of all possible situations. This way you will understand in which cases the code can cause problems after certain changes. Check for “dangerous moments” in complex code, where there might be errors.
Every time you find a bug, create a test case before you start fixing it. Apply test cases. There are different types of software testing, and each methodology performs a specific function. It is optimal to start with unit tests, integration, and regression testing.
Also, application testing can be comparative, and complex, determining the load and performance. There are acceptance testing, black and white box testing, compatibility testing, regression testing, unit testing, and usability testing (ergonomics research).
And the list of methodologies does not end there. Understanding the differences between them gives the realization that verification is not an additional option, but a necessity.
Testing is difficult and incomprehensible
Any process seems complicated when you are not familiar with it and do not know what stages it consists of. But it is worth paying a little interest, patience, and attention, as everything becomes clearer and simpler.
The more you know about the stages of creating a high-quality IT product, the more successful the solution you come up with will be.
Do not be lazy, read a few articles or an understandable book about testing, and discuss software quality control with familiar developers. This will help you learn more about the nuances of testing and understand which methods are preferred specifically for your application.
Testing slows down and lengthens development time
Indeed, application testing requires a certain amount of time. When you are first introduced to this stage, it may seem to you that everything has become longer and more complicated.
But over time, testing will become a familiar and integral part of development, without which it will be difficult for you to imagine the process of creating a product.
Further testing, on the contrary, will save time and resources. Autotests allow you to check the operation of the application with a single keystroke, and you will be sure that everything works as you expected.
All this will give confidence in the quality of the mobile application and its reliability. And even if there are any problems, you can quickly find the cause of the error by simply running one of the tests.
Over time, testing will not be perceived by you as something additional – you will understand that this is a necessary step for constant confidence in the quality of a software solution.
Do not be afraid to implement tests, and the resources spent on them will definitely pay off. And you can save on something else.
