A test manager is planning the integration of a new firmware module with a hardware board that is being developed in parallel by another team. The hardware team has a different schedule and the board is not yet available. What is the best way to coordinate testing with the hardware team?

Ask the hardware team to deliver a partial board early, even if it is not fully functional

Use a hardware emulator to test the firmware in the meantime, and plan joint integration testing when the hardware is ready

Wait until the hardware is available before starting any testing

Test only the firmware on a development PC and skip hardware integration testing

A team is developing a new smart meter for electricity consumption. The meter has a low-power microcontroller and communicates via a wireless protocol. The test manager is planning the performance testing level. What is the most important performance aspect to test for this device?

The memory usage of the firmware

The response time of the user interface on the meter's display

The throughput of the wireless communication link

The power consumption during normal operation and communication

A company is developing a new industrial robot controller. The controller has a safety-critical function that stops the robot when a human enters the work cell. This function uses a sensor that has a known failure rate. The test manager must decide how to allocate limited test time. Which approach best applies risk-based testing?

Defer testing the safety stop until the end, as it is complex and time-consuming

Test all functions equally to ensure balanced coverage

Focus on testing the robot's movement speed, as it is the most visible feature

Test the safety stop function extensively, including fault injection on the sensor, because the impact of failure is catastrophic

A test team is setting up a test environment for a new automotive infotainment system. The system includes a head unit, a display, and a CAN bus interface. The team needs to test the system's response to various CAN bus messages. Which tool/infrastructure is most appropriate for this testing?

A full vehicle test rig with all electronic control units (ECUs) connected

A network protocol analyzer for Ethernet, since CAN is a type of Ethernet

A simple serial port monitor to capture output from the head unit

A CAN bus simulator that can generate and monitor CAN messages, connected to the head unit

A team is developing a new drone flight controller. The controller has a real-time operating system (RTOS) and must respond to sensor inputs within strict timing deadlines. The test manager is planning the system test level. Which aspect is most critical to test at the system level?

The compatibility of the drone with different remote controllers

The battery life of the drone during normal operation

The end-to-end latency from sensor input to actuator output under various load conditions

The user interface for configuring the drone's flight parameters
