Water Bottle Test Cases Example

Test Case For Water Bottle Test Cases

In this post, we are going to discuss what should be the possible test case or scenarios for a water bottle. So before going to write the test case for a water bottle, I suggest asking yourself a few questions like how to test a water bottle, I would have liked to ask a few questions like:

• Is it a bottle made up of glass, plastic, rubber, some metal, some kind of disposable material, or anything else?
• Is it meant only to hold water, or we can use it with other fluids like tea, coffee, soft drinks, hot chocolate, soups, wine, cooking oil, vinegar, gasoline, acids, molten lava (!), etc.?
• Who is going to use this bottle? A school going kid, a housewife, some beverage manufacturing company, an office-goer, a sportsman, a mob protesting in a rally (going to use as missiles), an Eskimo living in an igloo or an astronaut in a space ship?

These kinds of questions may allow a tester to know a product (that he is going to test) in a better way. In our case, I am assuming that the water bottle is in the form of a pet bottle and made up of either plastic or glass (there are 2 versions of the product) and is intended to be used mainly with water. About the targeted user, even the manufacturing company is not sure about them! (Sounds familiar! When a software company develops a product without a clear idea about the users who are going to use the software!)

Test Case Scenario For Water Bootle

• Check the dimension of the bottle. See if it actually looks like a water bottle or a cylinder, a bowl, a cup, a flower vase, a pen stand, or a dustbin! [Build Verification Testing!]
• See if the cap fits well with the bottle. [Installability Testing!]
• Test if the mouth of the bottle is not too small to pour water. [Usability Testing!]
• Fill the bottle with water and keep it on a smooth, dry surface. See if it leaks. [Usability Testing!]
• Fill the bottle with water, seal it with the cap and see if water leaks when the bottle is tilted, inverted, squeezed (in case of a plastic made bottle)! [Usability Testing!]
• Take water in the bottle and keep it in the refrigerator for cooling. See what happens. [Usability Testing!]
• Keep a water-filled bottle in the fridge for a very long time (say a week). See what happens to the water and/or bottle. [Stress Testing!]
• Keep a water-filled bottle under freezing conditions. See if the bottle expands (if plastic made) or breaks (if glass made). [Stress Testing!]
• Try to heat (boil!) water by keeping the bottle in a microwave oven! [Stress Testing!]
• Pour some hot (boiling!) water into the bottle and see the effect. [Stress Testing!]
• Keep a dry bottle for a very long time. See what happens. See if any physical or chemical deformation occurs to the bottle.
• Test the water after keeping it in the bottle and see if there is any chemical change. See if it is safe to be consumed as drinking water.
• Keep water in the bottle for some time. And see if the smell of water changes.
• Try using the bottle with different types of water (like hard and soft water). [Compatibility Testing!]
• Try to drink water directly from the bottle and see if it is comfortable to use. Or water gets spilled while doing so. [Usability Testing!]
• Test if the bottle is ergonomically designed and if it is comfortable to hold. Also, see if the center of gravity of the bottle stays low (both when empty and when filled with water), and it does not topple down easily.
• Drop the bottle from a reasonable height (maybe a height of a dining table) and see if it breaks (both with plastic and glass model). If it is a glass bottle, then in most cases, it may break. See if it breaks into tiny little pieces (which are often difficult to clean) or breaks into nice large pieces (which could be cleaned without much difficulty). [Stress Testing!] [Usability Testing!]
• Test the above test idea with empty bottles and bottles filled with water. [Stress Testing!]
• Test if the bottle is made up of material, which is recyclable. In the case of plastic made bottle tests, if it is easily crushable.
• Test if the bottle can also be used to hold other common household things like honey, fruit juice, fuel, paint, turpentine, liquid wax, etc. [Capability Testing!]

These were a few test ideas, which occurred to me in a short session. Try to take this as a testing exercise and see if you are able to generate some more interesting test ideas (I am sure you can). I would be more than interested to see your test ideas. Let me (and others) know about your test ideas by leaving behind a comment. Thanks.
