How to Test a Website Manually

Creating a website is a complex process where each team member performs specific actions. Web testing is critical for creating a valuable resource because the testing quality will determine the project's success. As practice shows, many developers need to pay more attention to this stage, relying solely on their knowledge and experience. And what do we get as a result? Errors that lead to colossal expenditures of time, effort, and money. A resource that malfunctions elicits negativity from users, causing a decline in trust in the company and adversely affecting its reputation. Website testing can account for up to 50% of the time and budget. In this article, we will explain where this figure comes from and how to test a website manually, detailing its stages and types. 

What Exactly is Manual Testing? 

Manual testing manually analyzes software to help ensure that it meets specific requirements and works as intended. Unlike automated testing, which relies on pre-written tests, manual testing involves human testers who closely observe test cases, observe application behavior, and report problems encountered. Manual testing will be performed on a website, including verification of functionality, interaction, and interactivity through the active participation of the tester. 

In contrast to automated testing, which utilizes predefined scenarios, manual testing entails the tester's active engagement with the website to identify potential issues and shortcomings. Critical aspects of manual testing encompass exploratory testing to study functionality, verify correct operation, test on various devices and browsers, assess user-friendliness, and identify potential security issues. Manual testing is crucial for ensuring quality and user satisfaction on the website.  

Companies can detect flaws and assess customer experience for their online websites with the help of manual testers. You can also discover the advantages of our manual testing services and how they can benefit your project.
