Can we scale down the tests? Part 2

Sometimes you have a harmonica with the wrong scale. It is hard to scale it down.  A simple solution is to buy harmonicas in all scales. It will cost time and money, but it might save the day.

If a manager walks into your cubicle with a suggestion to scale down tests, then it is time to get the big picture before the decision to skip tests. Let’s go back to George.

Quality is an option
At eleven o’ clock in the morning George joined the meeting of the software testers. Cynthia was not looking very happy.
“What’s wrong with you, Cynthia?”, George asked.
“Management decided to skip the user acceptance test for the navigation system to save time.”, Cynthia answered.
“Did you point out the consequences?”
“Of course the interface can really be improved.”
“Can you prove it?”
“Sure.”
“OK, let’s call the PO for his opinion.”

John joined the meeting of the software testers.
“Hi Cynthia, this is supposed to be a tester only meeting.”
“You are welcome.” Cynthia reassured him. “We won’t bite you.”
“Would you give me a permission to let the other testers have a look to the navigation system?”
“No problem.”

George was studying his laptop.
“According to the user story it is possible to enter the right destination using voice commands within 10 seconds.
Your aunt asked you to come to Paris, which is in the neighborhood of Tupelo.”

First test:
“The destination is Paris.”, Pete said.
“What is destination?” was the answer of the navigation system.
“I want to go to Paris.”
“What means “I want to”?”
“Go to Paris.”
“Go to Paris go to Paris is an invalid voice command.”

Second test:
“Go to Paris.”
“Do you want to go to Paris in Arkansas, Paris in California, Paris in Idaho, Paris in Illinois, Paris in Kentucky, Paris in Maine, Paris in Michigan, Paris in Mississippi, Paris in Missouri, Paris in New York, Paris in Ohio, Paris in Pennsylvania, Paris in Tennessee, Paris in Texas, Paris in Virginia, Paris in Grant County in Wisconsin or Paris in Kenosha County in Wisconsin?”

Third test:
“Go to Paris in the neighborhood of Tupelo.”
“What is neighborhood?”
“Begin again.”
“Go to Paris, which is near Tupelo.”
“How far is near?”
“I don’t know.”
“Give an estimation.”
“I don’t know.”

Fourth test:
“Go to Paris via Tupelo.”
“Do you want to go to Paris in Arkansas, Paris in California, Paris in Idaho, Paris in Illinois, Paris in Kentucky, Paris in Maine, Paris in Michigan, Paris in Mississippi, Paris in Missouri, Paris in New York, Paris in Ohio, Paris in Pennsylvania, Paris in Tennessee, Paris in Texas, Paris in Virginia, Paris in Grant County in Wisconsin or Paris in Kenosha County in Wisconsin?”

Fifth test:
“Go to Tupelo.”
“The destination is Tupelo.”
“Go to Paris, which is closest to Tupelo.”
“Give an estimation.”
“Uuuuuh.”
”What is Uuuuuh?”

George looked at the PO:
“Do you think, that a user acceptance test is a considerable option?”

Sound check (and other interesting things in other backyards)

Xoun is a strange brand name to pronounce. The question is, whether this sounds right to shopping people. If you turn the picture upside down, you will read a known brand name in the Netherlands. (Which I associate with a mug with welcome warm soup after hours of sailing on the lakes in Friesland.) By taking a different view some things might need more attention than you might expect. In this article I will tell about three situations, in which non IT related information can be helpful for an IT engineer.

Granting a small favour

In the nineties my customer planned in a special activity to introduce internet to his employees. So I ended up talking with a woman from the legal department. She stated, that shipping information should always be mentioned. It would save her department and company a lot of time and money.

A few weeks later it was time for my courtesy call. I called the lady from the legal department. After a short introduction I came to the point: “I just discovered, that your company is selling products on the internet. I could not find the shipping information.” A silence followed, so I had to repeat the message. A muffled “Thank you” followed. A few days later the web shop was off line.

In case of surprise

A special meeting was planned and the project manager was constantly talking about Rbbit. After a while I figured out, that the Rbbit was not a nice white fluffy animal appearing in the magician’s hat, but a Big Bug in the software system. “Two weeks ago we had a Rbbit. Last week we had a Rbbit. What do you expect for next week?” I answered, that another Big Bug would show up. “What are we going to do?”. I spoke up again: “I would set up an emergency procedure.” The project manager was not pleased with the answer: “Do you expect, that I will restore the complete database?”

“If wrong information is sent to the customers, then a new mail must be sent to them, that they should ignore the information in the sent mail. You could also add information, when the right information will be sent. The next step is to investigate and solve the problem.” The project manager finally agreed: he needed phone numbers of people in the operations department and operational measures.

What’s it in for them?

As a software tester it is very tempting to use different plug ins in your browser to analyse web sites. During one of my trials I encountered a tool, which provided me much information. I did not understand, why the tool was given away for free. The web site for the plug in tool was basically stressing the benefits. At that moment I was doubtful, whether I had installed malware.

After more extensive searches on the web I discovered a related business web site, which offered information about websites. This information was gathered by users using the above mentioned plug in. So the business model was as follows: determine, which information is useful for IT people. Provide a free tool for collecting information and sell the gathered information with a nice profit.
