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.

Why don’t you take this as a Testing Challenge and develop your test ideas? Let me (and others) know about your test ideas by leaving behind your comments.

I love open-source technologies and am very passionate about software development. I like to share my knowledge with others, especially on technology that's why I have given all the examples as simple as possible to understand for beginners. All the code posted on my blog is developed, compiled, and tested in my development environment.
