Bjarne Stroustrup Quotes

Testing, we will never do enough of it.

Running the test suite like this allows us to catch problems when they are just introduced.

I used Agitator on some code I had unit-tested, and it made me a better tester. As an Agitar Fellow, I look forward to the leverage of working with an outstanding organization as together we continue to improve the value of developer testing.

Testing can be used to show the presence of bugs, but never to show their absence!

The real value of tests is not that they detect bugs in the code but that they detect inadequacies in the methods, concentration, and skills of those who design and produce the code.

One of the headaches of high-tech test programmes is having to debug the test arrangements before you can start debugging the things you're trying to test.

No trusting without testing

A very important part of game development is testing - something that a lot of developers don't do.

Beware of bugs in the above code; I have only proved it correct, not tried it.

I found out that most programmers don't like to test their software as intensely as I do.

Writing software that's safe even in the presence of bugs makes the challenge even more interesting.

Today, we can tell people we have a testing process and facilities in place on a nationwide basis.

Yet we still see continuous reports of bugs.

We have a very active testing community which people don't often think about when you have open source.

Developer testing is an important step towards accountability. It gives developers a way to demonstrate the quality of the software they produce.

I'm not saying we purposely introduced bugs or anything, but this is kind of a natural result of any complexities of software... that you can't fully test it.

Trust but verify. Doveryai no proveryai.

As you get to the end of the project you want to run all the tests cases against one version and make sure that you know that that version passed everything. And so as you get late in the project you get a little more conservative about making radical changes to the software.

Testing shows the presence, not the absence of bugs.

When you develop software, the people who write the software, the developers are the key group but the testers also play an absolutely critical role. They're the ones who ah, write thousands and thousands of examples and make sure that it's going to work on all the different computers and printers and the different amounts of memory or networks that the software'11 be used in. That's a very hard job.

... it is a fundamental principle of testing that you must know in advance the answer each test case is supposed to produce. If you don't, you are not testing; you are experimenting.

Like any well designed software product, Windows is designed, developed and tested as an integrated whole.

People appreciate a good product, a stable system. They want to communicate easily and use a product that just works.

I think a beautiful product that doesn't work very well is ugly.

It takes a long time to get a reputation for quality. There are people in our industry, they're basically copiers. Look at the cars on the streets. They all look alike. But if you put quality into a product, then have it validated, you have huge credibility.
