It suggested that software developers need not see themselves as part of the engineering tradition and that a different metaphor would be more suitable. In his August keynote at Agile , Robert C. Martin proposed a fifth value for the Agile Manifesto, namely "Craftsmanship over Crap". He later changed his proposal to "Craftsmanship over Execution".

In December , a number of aspiring software craftsmen met in Libertyville, Illinois , with the intent of establishing a set of principles for software craftsmanship. Three months later, a summary of the general conclusions was decided upon. It was presented publicly, for both viewing and signing, in the form of a Manifesto for Software Craftsmanship.

In April , two of the companies in the software craftsmanship movement, 8th Light and Obtiva , experimented with a "Craftsman Swap. These maps where created long ago by other people and I have been gradually cleaning up their code and adding features. You can contract me for development work, advise and training.

Jeroen De Dauw Software Craftsman. Wikimedia Deutschland fundraising After leading the creation of this application I have written and spoken multiple times about its architecture.

Diff Small library for representing, computing and applying diffs between structured data. DataValues Geo Small library for parsing, formatting and representing coordinates. ParamProcessor Processes parameters in declarative fashion. Simple Cache Tiny library defining a minimalistic caching interface and provides some basic implementations. Euro PHP value object for representing a positive amount of Euro. Example: Time depending on Watch time should be meaningful without a Watch.

Craftsmanship is also about testing: ATDD and Test First being the most obvious patterns but everything that enables built-in quality is also part of this set of practices for in agile testing, we need to prevent bugs rather than finding them. Use automated Acceptance Test Driven Development for regression testing and executable specifications. A combinatorial method of software testing that, for each pair of input parameters to a system typically, a software algorithm , tests all possible discrete combinations of those parameters.

Start developing Unit Tests with tiny little steps. Add only a little code in test before writing the required production code. Then repeat. Add only one Assert per step. This happens whenever a case was not addressed in a unit test, then you should write a unit test that reproduces the defect — Fix code — Test will succeed — Defect will never come back.

Otherwise, the result could be tests that increase code coverage but not certainty. Code coverage is much weaker than Branch cov. Coverture should be adapted with failure impacts severity. Always unit test boundaries. Do not assume behavior. Parameters may have boundaries from business require them from the Product Owner values and also from code e.

Intervals between boundaries should be tested on valid AND invalid intervals. When unit testing, dependencies must be faked to isolate behaviors. If your test needs a lot of Test Doubles mocks, stubs, fakes This family gathers practices directly related to coding habits, the Coding Guidelines being the most basic pattern that every Dev should comply to. The steps a name goes through are:. A Code smell deserves a refactoring to remove it.

Each code smell has a subset of applicable refactoring techniques. Exceptions should be thrown as early as possible after detecting an exceptional case e.
