Testing at the planning stage
A strategy and various scenarios of user interaction are being written.
Testing websites and applications
QA testing of websites and applications | Quality assurance
Professional testing of websites and mobile applications. Functional, load, and UX/UI testing. We identify 98% of errors before release. Certified team of QA engineers.Why test IT products?
- Testing helps to verify the functionality, performance, and security of the software.
- First, determine the requirements for the internal structure and graphical interface of the application. Testing helps you find errors so that you can fix them later.
- A properly tested IT product will protect the client from financial losses, negative user reviews, and the removal of applications from devices.
Engineers who testing digital products are divided into two categories:
- quality assurance (QA);
- quality control (QC).
The task of quality control testers is to prevent errors and ensure compliance with software standards. They identify defects in the finished product to achieve high quality. Regular testing of a website or application allows you to track the smallest processes in the lifecycle of a complex IT product and identify its strengths that can retain users.
Key stages of testing
2
Testing during development
Verification of individual components for compliance with requirements and verification of integration quality.
3
Post-development testing
Evaluation of functionality, safety requirements, design quality, and user convenience.
4
Real-world testing
Further testing in real conditions allows the tester to make sure that the functionality is working correctly. The specialist conducts regression tests and evaluates compatibility with new development versions.
Testing effectiveness indicators:
- all customer requirements have been met;
- all possible scenarios and test cases have been worked through;
- risks of software malfunction and user experience issues have been eliminated;
- the necessary level of data security and confidentiality has been ensured;
- all defects and risk factors have been identified and eliminated.
Stages of testing a website or mobile application:
- 1
Creating a testing strategy and test cases
QA and QC engineers study the IT product documentation and customer requirements for implementation in detail: functionality, target user audience and its requests, application type (native, cross-platform, service, or PWA). Based on the requirements, a strategy for testing the website or applications, deadlines, methodology, and user experience scenarios for each of them are created.
- 2
Modular testing
Testing includes checking the functionality and automation of software components to ensure that they perform their intended tasks. Modules are tested both in conjunction with and in isolation from other parts of the system.
- 3
Integration testing
The correctness of the website's interaction with external APIs, databases, and third-party services must also be checked for errors.
- 4
System testing
Complete verification of the system for compliance with requirements: functional, performance, security analysis, and user scenario testing. The website or mobile application is tested for compatibility with various devices.
- 5
UI/UX design testing
Assessment of the design's compliance with the parameters of usability, attractiveness, clarity, responsiveness, and speed of command execution.
- 6
User testing
First, a specialist checks the product's performance in real-world conditions, then collects feedback from a selected group of users who test the system's correct operation.
- 7
Completion of testing
At all stages of testing, QA and QC engineers compile reports on the tasks performed and the problems identified, which are sent for review and correction. The reports include recommendations and analysis of the problems identified in order to improve websites or applications. The results are stored as documentation for future analysis of work processes.
QA and QC engineers are needed to identify vulnerabilities in the system and raise the level of functionality of the IT product.
