In this article we are going to write test cases to test a toaster. There are different designs of toasters available in the market. Most of the toaster designs these days are available in two types – battery operated or electrical. Depending on how you choose to test the appliance, the test cases will be different. We are going to take a look at some of the test scenarios and cases for both of these types.
Before we write long list of scenarios and test cases, let’s get one thing clear. The best way to test a toaster is to check if it toasts bread as per our requirement. That’s it. There is nothing more to it than this simple test scenario. However in real world, in order to get closer to this output, the toaster has to go through a process. While going through this process, it may overheat or underheat the bread. If it’s battery operated then it could run out of energy. Like this we can think of many scenarios in positive and negative situations. So let’s take a look at those scenarios and also check some test cases as well.
If the question like this is asked in the interview, please start your test case with simple test scenario of heating the bread. From here onwards you can get creative with different scenarios and test cases. Also you can ask for scenarios like if the toaster is for home made usage or the restaurant type. As the designs are different for each of the use cases.
Let’s take a look at the test cases & scenarios for testing a toaster.
- Connect the power cable to the appliance and check if it turns on the toaster.
- Check if the power light is visible on the appliance.
- Check if the power light shows once the toast is prepared.
- Check if the power cuts itself off once the toast is ready.
- Put the bread into the toaster and turn on the device. Observe the behavior.
- Check if it toasts the bread after specific time interval.
- Check if the power remains on if the bread is not added into the toaster.
- Check if the power gets cut off if the bread is removed from the toaster.
- Check if the toaster requires heat after the first bread gets toasted.
- Add the next slices after the first one is heated to check how much time it takes.
- Check if the toaster accepts more slices than the space allocated.
- Check how many slices can be toast on the battery.
- Check if the toaster works by turning off the electricity.
- Check if the color and smell of the toaster changes after heat in particular time period.
- Check how much power supply it takes for toaster – 2 phase or 3 phase.
- Check how much power it takes for toaster during different room temperature.
- Check the moisture of the toaster if heated for certain time period.
- Check if the toaster is automated or manual.
- Check if you can set the toaster timing.
- Check how thick slice can be added into the toaster.
- Check if the bread slices is possible to overheat.
- Check if the timer setting in toaster prevents overheating of slice.
- Check if the toaster color, size and weight is as per the specification document of manufacturer.
- Check how many breads can be toasted for lifespan of the toaster.
- Check how much idle time requires in between the toasting.
- Check for stress on the appliance.
- Check the amount of power consumed for number of toasts.
- Check for the auto cut off operation in different conditions.
- Check for the operation of the toaster with battery backup.
- Check if the toaster operates on the solar power supply.
- Check how many toasts can be made if operated for long hours.
These are some of the test cases that you can write for most generic toaster. I have assumed electrical toaster for our test scenarios and test cases. However you can check other types like battery operated and solar supply toasters. This way you can come up with few more test cases.
