✍️ Sample CAST Questions & Answers

1. Coordinating a multi-crew test project requires clear:
Communication of roles, timing, and equipment status

Clear communication of responsibilities and equipment state keeps crews coordinated and safe.

2. During which phase of the Software Testing Life Cycle (STLC) are the specific test cases and scripts developed?
Test Design

The Test Design phase is where testers create detailed test cases and test scripts based on the test objectives and requirements identified during the Test Planning phase. Test Planning involves defining the strategy, Test Execution is running the tests, and Test Closure involves summarizing and reporting on the testing effort.

3. What is the main purpose of 'exploratory testing' within an Agile sprint?
To simultaneously learn about the system, design tests, and execute them without rigid scripts

Exploratory testing combines learning, test design, and execution simultaneously, making it highly effective for discovering unexpected issues quickly in sprints.

4. A tank holds 150 gallons and drains at 12.5 gallons per minute. How long until it is empty?
12 minutes

150 ÷ 12.5 = 12 minutes.

5. What is a key challenge when testing in short Agile sprints of one to two weeks?
Balancing the execution of new feature tests with maintaining the regression suite within a compressed timeframe

Short sprints require testers to write, execute, and automate new tests while keeping the regression suite manageable—all within the same iteration.

6. A transformer steps voltage down by a 4:1 ratio. If the input is 480 volts, what is the output?
120 volts

480 ÷ 4 = 120 volts.
