Microwave Oven Test Cases

• 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 Max power consumption (1000W, 1150W, 1200W, 1210W, 1450W etc)?

Test Cases For Microwave Oven

• Test the structure and dimensions of the microwave and see if it conforms to the specified dimensions mentioned in the user manual. [Build Verification Testing!]
• Test if the door of the oven fits squarely and securely and opens and closes smoothly. [Installability Testing!]
• Test if the door hinges are in proper condition, and the surface of the door is not damaged.
• Test if there is no corrosion is evident on the door, 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. [Usability Testing!]
• Test if the microwaves generated in the microwave oven cease to exist once the electrical power to the magnetron is turned off.
• Test how the microwave performs under different voltage conditions. Test how it is able/unable to sustain fluctuating voltage. [Performance Testing!]
• Test the power consumption of the microwave.
• Switch ON the oven for a very long time (say up to 12-24 hours continuously) and see the result. Test if the thermostat works fine under such a situation. [Stress Testing!]
• Test if the timer is working, and the microwave switches off automatically after the preset time. [Usability Testing!]
• Keep the oven door open and test if you can set a timer for cooking. [Usability Testing!]
• Test if you can switch off the microwave before the timer has counted down to the present time. [Usability Testing!]
• Test the cooking time for different food items. [Performance Testing!]
• Test if the oven results in uneven absorption causing localized “hot spots”.
• Test if the bowls made up of glass and plastics are heated when used in the oven. Ideally, they should not. [Usability Testing!]
• Test if parts of frozen food remain frozen if insufficient time is allowed for the heating process.
• Test if microwaves do not directly heat the oven walls and other non-metallic cooking utensils.
• Test if the microwave exposure causes serious health effects such as deep tissue burns and hyperthermia. Test if it either causes or promotes cancer. [Security Testing!]
• Test if the microwaves make the food or the oven radioactive. [Security Testing!]
• Test if the safety interlock switches stop the generation of microwaves immediately the door is opened. [Security Testing!]
• Test that there is no microwave leakage from the device. If it is there, it should not exceed the recommended limit (differs from country to country).
• Test if cardiac pacemakers are likely to be susceptible to microwave interference, when very close to an oven. [Security Testing!]
• Test the operation of the oven 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. [Security Testing!]
• Test by using the oven for sterilizing baby bottles or other food utensils. [Capability Testing!]
• Test if closed containers and eggs explode when heated in the microwave oven due to the pressure build-up of steam. [Security Testing!]
• Try to heat grapes in the oven and see if it explodes due to arcing! [Security Testing!]

These were a few test ideas that came to my mind while attempting to generate ideas to test a microwave oven. But I am sure there can be a lot more test ideas like these. Why don’t you take this as a Testing Challenge and come up with your very own test ideas? Let me (and others) know about your test ideas by leaving behind your comment.
