A test comparator is a tool used in software testing to compare the actual output of a program with the expected output.

This comparison helps to identify any discrepancies or errors in the software code, allowing developers to pinpoint and rectify issues efficiently. The test comparator works by running test cases on the software and capturing the output generated by the program.

This output is then compared against the expected output, which is predetermined based on the requirements and specifications of the software.

The comparator highlights any differences between the actual and expected outputs, enabling testers to identify bugs, defects, or inconsistencies in the code. By using a test comparator, software developers can ensure the accuracy and reliability of their programs.

It helps in validating the functionality of the software and ensuring that it meets the desired standards and requirements.

This tool is essential for quality assurance and plays a crucial role in the software development process. In conclusion, a test comparator is a valuable tool for software testing that aids in the identification and resolution of bugs and errors in the code.

It helps in improving the quality and performance of software applications, ensuring a seamless user experience.

By utilizing a test comparator, developers can streamline the testing process and deliver high-quality software products to their clients.
