Sometime back, I was asked to train a few fresher, its a new learning I had, which I am sharing with you. I asked them to imagine a bug and write test reports, after giving some gyaan. I was suprized to see the examples, they came out with, which left me thinking; was I as smart as these fresher's?
Also, when I asked them to come out with Load and Stress test cases for any product, they can imagine, I again, learnt from them, the examples and test cases for Rubber band, Shoe...
I found the examples of Rubber band and Shoe for Load and Stress testing, a very thought provoking ones. Thanks to the freshers, I learnt a great deal from them.
I just did not give them some exercises but I also did the homework, what they did, taking their examples, to check whether I am a good tester.
_ Bug report _
Disposable cup bug
Summary – The disposable cup leaks when a hot drink like coffee or tea exceeding 95 degree centigrade is allowed to remain in the cup for a time of about 15 minutes.
Cup type: Hard Paper cup
Manufacturer: XYZ Corporation
Customer: ABC Corporation
Test Content: Hot Coffee/Tea (> 95 degree centigrade)
Test Case mapping: TC_43_HT_LQ
Steps to Reproduce –
1) Take 3 – 4 disposable cups for testing.
2) Place them on a table and ensure the room temperature is below 40 degree centigrade.
3) Prepare coffee and/or tea and check/ensure the temperature of the tea or coffee is above 95 degree centigrade.
4) Pour the prepared hot coffee/tea into the cups on the table and ensure, each cup has different volume. (For ex – 1st cup contains half cup coffee, 2nd cup 3/4th coffee)
5) Repeat the above steps for a different sample/batch of cups.
6) Repeat the above steps with other hot liquids such as hot water, hot malt drinks…
Observed Result –
1) After around 10 minutes, all cups under test, having different volume of hot liquids, start to leak. (The leak is from the bottom of the cup)
2) The hot liquid leaks entirely out of the cup in one minute, when the cup was filled for full up to brim.
Expected Result –
1) The cup should be able to hold hot liquids (90 – 100 degree centigrade)
2) As per specification, the cup should not leak when a hot liquid is allowed to remain in it for an hour.
Reproducibility – 100 %
Suggested temporary fix –
As per experiments, it is found that, if two cups are used one over the other, the hot liquids are held and does not leak out for an hour.
Recommended permanent fix –
Consider re looking at the material/thickness of the paper and glue.
Risk of the bug –
Customer will be annoyed to see the tea/coffee has leaked and the customer is forced to clean the surface where the cup was placed. There could be some important documents/dress/money/anything important that may get spoilt because of the leak.
Limitation of testing –
1) The above scenario was reproduced using hot coffee and tea only.
2) It is not experimented with hot water or any other liquid.
3) No testing was carried out to find whether the glue making the coffee/tea toxic.
_ End of bug report _
Now I have some points, I want you to go through -
- If you are training, freshers, ensure, you do not misguide them.
- Do not limit their thinking to software, make them run into wildlife, they shall make you think, in turn.
- Teach them examples, dont put them on the project, directly.
- Give things in bits and pieces and not macro blocks, which is hard to digest for a fresher.
- Teach them; how to search on google?, else, you learn it first.
- Ask them to choose any product, they like, and test, first, before, you make them test junk.
- Dont limit the training to your needs, give them an opportunity to learn and experiment.
- Stress on the importance of English skills, in software testing, never mind, you may not have it.
- Make them enthusiastic about work and not excited about work.
- When you do not know something say "Can I refer to something before I tell it clearly?".
- To know the complexity of the homework, you are giving, you too work it out, at your home.
- There are more points, you yourself, need to explore.
