Top Software testing Tools

Software Testing has evolved a lot since the early 2000’s. Incorporation of AI and Automation have leveraged the capabilities of software testing tools. From using Automation frameworks, teams have started to adopt AI-Powered Testing Tools that helps with speed, and, Accuracy thereby ensuring faster code shipment.

Additionally, these software testing tools have also enabled teams to effortlessly automate complex test cases as well as reduce the mundane efforts required in Manual Testing. When it comes to the Agile QA process, Software Testing Tools come in handy for software testing teams. This gives Software testers the advantage and flexibility to embrace new changes, ensure clear documentation, shorter as well as faster feedback cycles, better code quality, etc.

What is Software Testing?

Software Testing is the process of testing and validating the complete software application to determine whether it works as intended or not. Moreover, software testers evaluate the respective application from the aspects of Web, API, Accessibility, etc.

In a nutshell, software testers evaluate the product based on usability as well as functional capabilities. The two major classifications of software testing include manual testing and Automated Testing.

Categories of Software Testing

Web Testing

Web Testing is the process of testing a web application’s functionality, performance, security, and quality against expectations. QA Engineers generally evaluate the UI, performance, security of the developed application.

Moreover, they also perform cross-browser testing, in which the web application is tested across different browsers as well as screens.

Visual Testing

Visual Testing is the process by which software testers evaluate the application’s GUI (Graphical User Interface) with the expected outputs.

Misalignment in UI components, CSS, etc., are tested. In a nutshell, end-to-end visual changes are detected in Visual Testing. These are flagged as bugs and then sent to the development team for corrections.

API Testing

API Testing is a type of testing in which the functionality of all the API’s in the application is tested.

Functionality, security, as well as response time of the API’s are tested. Bugs are flagged and reported to the development team.

Accessibility Testing

Accessibility testing is a type of software testing that verifies if the application is accessible to users with disabilities, such as Visual, auditory, cognitive, and motor impairments.

Moreover, the application is also made sure to comply with the WCAG standards guidelines. The main goal of this testing is to ensure that people with disabilities can access the application.

Mobile Testing

Mobile Testing is the process by which the mobile application’s performance, security, and functionality are tested across different platforms such as Android and iOS before the end user uses the product.

What is a Software Testing Tool?

A Software Testing Tool is a tool that helps software testers perform end-to-end testing of an application. Web, API, Accessibility, Mobile, and Visual testing can be performed seamlessly with a software testing tool.

Modern software testing tools empower AI and No-code to leverage the testing process. Additionally, it also helps software testers to increase the quality of their code shipment within a shorter span of time. Test case generation, test case management, test execution, test automation, as well as test maintenance can also be performed in software testing tools.

Advantages of a Software Testing Tool

• Faster Time: By adopting a Testing Tool, QA teams can easily automate the complete testing process, which can save time and increase productivity by 10x.
• Reduced Human Errors: Errors that can be missed by human eyes while performing manual testing can be avoided.
• Easy Maintenance: All the test cases can be maintained in a single platform, which makes the job easier for testing teams.
• Automation Velocity: Teams that use AI-powered software testing tools have reported a 10x increase in test automation.
