According to the testing principles, what is an important aspect of early testing?

An important aspect of early testing is that it helps to uncover defects sooner in the development process. This principle is vital because identifying issues while the product is still being developed allows for more efficient fixes and less costly changes compared to later stages, where problems can become more complex and entrenched. Early testing promotes a proactive approach, where testers and developers can address potential issues before they escalate, ultimately leading to better software quality and user satisfaction.

This practice supports iterative development methodologies, where feedback and adjustments are made throughout the development cycle, rather than waiting until the end, which can result in significant delays and budget overruns. Early testing fosters collaboration among team members as well, as it encourages open communication about potential issues and shared responsibility for quality.
