Quotes & Sayings About Software Testing

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

Trying to improve software quality by increasing the amount of testing is like trying to lose weight by weighing yourself more often. What you eat before you step onto the scale determines how much you will weigh, and the software-development techniques you use determine how many errors testing will find. — Steve McConnell

Agitator and the Agitar Management Dashboard lower the barriers to accountability in software development and increase the value of developer testing. — Kent Beck

Zues?" I said.
"His computer. He named it." Then she whispered conspiratorially, "He acts like it's a person."
"I do not," he said as we walked down the hall toward his room.
"You gave it a birthday party," she said.
Grayson stopped walking for a moment. "Annual hard-drive maintenance and software upgrades do not count as a birthday party."
"No," she said. "But singing 'Happy Birthday' to it does."
He took a deep breath. They've obviously been through this before. "You know I was testing the new voice-recognition software."
Natalie looked at me. "Birthday party. — James Ponti

Most literature on the subject of agile methodology... is written from the viewpoint of software developers and programmers, and tends to place its main emphasis on programming techniques and agile project management - testing is usually only mentioned in the guise of unit testing and its associated tools. ...However, unit tests alone are not sufficient and broader-based testing is critical to the success of agile development processes. — Tilo Linz

Listening, Testing, Coding, Designing. That's all there is to software. Anyone who tells you different is selling something. — Kent Beck

I write them to improve my productivity as a programmer. Making the quality assurance department happy is just a side effect. Unit tests are highly localized. Each test class works within a single package. It tests the interfaces to other packages, but beyond that it assumes the rest just works.

Functional tests are a different animal. They are written to ensure the software as a whole works. They provide quality assurance to the customer and don't care about programmer productivity. They should be developed by a different team, one who delights in finding bugs. — Martin Fowler

Testing was never going to be fashionable, but you could hardly run a respectable software development shop with no testing effort at all. — Stephen Baxter

Testing by itself does not improve software quality. Test results are an indicator of quality, but in and of themselves, they don't improve it. Trying to improve software quality by increasing the amount of testing is like trying to lose weight by weighing yourself more often. What you eat before you step onto the scale determines how much you will weigh, and the software development techniques you use determine how many errors testing will find. If you want to lose weight, don't buy a new scale; change your diet. If you want to improve your software, don't test more; develop better. — Steve McConnell

Generative testing is an approach to testing software that was made popular by the QuickCheck library. Originally written in Haskell and since ported to several other programming languages (Ruby, Python, C, C++, Objective-C, Smalltalk, Java, JavaScript, Erlang, Scala, Clojure...), the QuickCheck library allows the developer to separate test logic from the generation of test cases. This means that, as developers, we can spend less time instructing the compiler how to test our code, and focus instead on what properties we expect our code to have. — Anonymous

You know, most people in the open-source world who use open-source software don't actually do builds themselves - those people just download the binaries. And so we expect that the big enterprise people will just do that and we will certainly be providing binaries that have been through full industrial-strength QA, that have been through all the conformance testing. — James Gosling

Software bugs are like cockroaches; there are probably dozens hiding in difficult to reach places for every one you find and fix. — Donald G. Firesmith

The essence of a software entity is a construct of interlocking concepts: [ ... ] I believe the hard part of building software to be the specification, design, and testing of this conceptual construct, not the labor of representing it and testing the fidelity of the representation. — Fred Brooks

The simplest answer is that the user had access to reality - every company builds a bubble around itself, where the products get built and tested in a more controlled environment than they get used in. This is especially true of complex software. What the early users enabled Xiaomi to see was how MIUI actually worked when real (albeit unusually technically proficient) people tried to install it on a wide variety of devices. — Clay Shirky
