Test Cases For Microwave Oven
Note: These context-based questions came to mind while generating test ideas for a microwave oven.
- What kind of model is it? A Solo model, Grill model, or a Convection model?
- What is the capacity (in terms of liters) of the oven?
- What is the microwave output (700W, 800W, 850W, etc.)?
- What is the maximum power consumption (1000W, 1150W, 1200W, 1210W, 1450W, etc.)?
Test Cases For Microwave Oven
- Check the structure and dimensions of the microwave and see if it conforms to the specified dimensions mentioned in the user manual.
- Check if the oven door fits squarely and securely and opens and closes smoothly.
- Check if the door hinges are in proper condition and the door’s surface is not damaged.
- Check if there is no corrosion on the door, hinges, or the oven interior.
- Plug the power terminal and see if the LED glows. And test if the oven is getting power supply. Also, test the current received and maximum allowed.
- Check if the microwaves generated in the microwave oven cease to exist once the electrical power to the magnetron is turned off.
- Check how the microwave performs under different voltage conditions. Test how it is able/unable to sustain fluctuating voltage.
- Check the power consumption of the microwave.
- Switch ON the oven for a very long time (up to 12-24 hours continuously) and see the result. Test if the thermostat works fine under such a situation.
- Check if the timer works and if the microwave switches off automatically after the preset time.
- Keep the oven door open and test if you can set a timer for cooking.
- Check if you can switch off the microwave before the timer has counted down to the present time.
- Check the cooking time for different food items.
- Check if the oven has uneven absorption, causing localized “hot spots”.
- Check if the bowls of glass and plastics are heated in the oven. Ideally, they should not.
- Check if parts of frozen food remain frozen if insufficient time is allowed for the heating process.
- Check if microwaves do not heat the oven walls and other non-metallic cooking utensils directly.
- Check if microwave exposure causes serious health effects such as deep tissue burns and hyperthermia. Test if it either causes or promotes cancer.
- Check if the microwaves make the food or the oven radioactive.
- Test if the safety interlock switches stop the generation of microwaves immediately after the door is opened.
- Test that there is no microwave leakage from the device. If it is there, it should not exceed the recommended limit (it differs from country to country).
- Test if cardiac pacemakers are likely to be susceptible to microwave interference when very close to an oven.
- Test the oven operation without a load (i.e., an absorbing material such as food or water). See if it results in fire hazards due to the resonance of the magnetron tube itself.
- Test by using the oven for sterilizing baby bottles or other food utensils.
- Test if closed containers and eggs explode when heated in the microwave oven due to the pressure build-up of steam.
- Heat grapes in the oven and see if they explode due to arcing!
A few test ideas came to my mind while attempting to generate ideas to test a microwave oven. But I am sure there can be many more test ideas like these.
