To achieve comprehensive test coverage despite a shortage of testing resources, prioritize and strategize testing efforts by focusing on risk-based testing. Identify critical functionalities and high-risk areas of the application, and allocate resources to test these thoroughly. Leverage automation to cover repetitive, time-consuming tasks, and execute regression suites efficiently. Incorporate exploratory testing to uncover edge cases, and ensure a collaborative approach by involving developers and stakeholders in the testing process. Additionally, use analytics and monitoring tools to identify gaps and optimize testing efforts for maximum impact.

In resource-constrained environments, prioritizing testing efforts is crucial for maintaining quality. Focus on risk-based testing, where you identify and test the most critical functionalities that could impact user experience or business objectives. Additionally, leveraging automation for repetitive tasks can free up valuable human resources for more complex testing scenarios, ultimately enhancing coverage and efficiency. Emphasizing collaboration among team members can also lead to innovative solutions and shared knowledge, ensuring that even with limited resources, the testing process remains robust and effective.

I would prioritize testing critical features and focus on areas with higher risk. Use automated tests where possible to save time and cover more ground. Additionally, I’d collaborate with the team to share the testing workload.

With limited resources, we cannot test everything so first is we need to find out the critical / most used functions and divide our testcases into 'must have' , 'should have' and 'not so important' categories to set the priority. Must have are the ones to be covered first followed by 'should have'. Automating the testcases from stable and repetitive used modules will also help in speeding up the execution and enhancing the coverage.

To achieve comprehensive test coverage with limited resources, focus on prioritizing critical test scenarios based on risk assessment and impact. Leverage automation tools to streamline repetitive tasks, maximizing efficiency. Additionally, adopt exploratory testing to uncover potential issues dynamically and optimize resource usage.
