Final answer:
Integration Testing should take place after the modules of a shopping website are assembled into a single website.
Step-by-step explanation:
After the developers of a software project team have assembled the modules of a shopping website into a single website, the important type of testing that should take place is Integration Testing.
Integration testing ensures that the modules can work together seamlessly and that data flows correctly between them. It helps identify any issues or conflicts that arise when combining the modules, allowing the team to fix them before the website is deployed.
For example, during integration testing, the team can check if the shopping cart module correctly communicates with the payment gateway module or if the user registration module properly interacts with the product catalog module.
