| 20 | |
| 21 | <p> |
| 22 | Efficient team work that produces high-quality software requires a common set |
| 23 | of rules. |
| 24 | </p> |
| 25 | |
| 26 | <h2>Consistent Source Tree</h2> |
| 27 | |
| 28 | <p> |
| 29 | Update your sources and run the build locally before every check-in. Commit |
| 30 | only if the build succeeds. |
| 31 | </p> |
| 32 | |
| 33 | <p> |
| 34 | Documentation is part of the product. Whenever you implement a new feature or |
| 35 | change existing behavior make sure to update all corresponding JavaDoc as well |
| 36 | as other documentation with the same change set. The product should always be |
| 37 | in a consistent state. For every change the following items should be checked: |
| 38 | </p> |
| 39 | |
| 40 | <ul> |
| 41 | <li>Corresponding JavaDoc.</li> |
| 42 | <li>Documentation referring to the modified concepts, interfaces or |
| 43 | implementation.</li> |
| 44 | <li>New features, bug fixes and modified behavior should be enlisted in the |
| 45 | <code>org.jacoco.doc/docroot/doc/changes.html</code> file together with |
| 46 | the corresponding issue tracker id.</li> |
| 47 | </ul> |
| 48 | |
| 49 | <h2>Design for Integration</h2> |
| 50 | |
| 51 | <p> |
| 52 | The primary focus of the JaCoCo project is to provide a code coverage library. |
| 53 | Integrators may want to embed JaCoCo in different tools and environments with |
| 54 | very different usage scenarios. Therefore following aspects should be considered: |
| 55 | </p> |
| 56 | |
| 57 | <p> |
| 58 | <b>Documentation:</b> All APIs should be properly documented on different |
| 59 | levels of granularity: |
| 60 | </p> |
| 61 | |
| 62 | <ul> |
| 63 | <li>General usage</li> |
| 64 | <li>Bundle summary</li> |
| 65 | <li>Package summary</li> |
| 66 | <li>Type description</li> |
| 67 | <li>Member description</li> |
| 68 | </ul> |
| 69 | |
| 70 | <p> |
| 71 | <b>Proper Units:</b> All APIs and internal implementation classes should form proper |
| 72 | units with well defined responsibilities and dependencies. Each class and method |
| 73 | should focus on a single concept. It should be possible to use different aspects |
| 74 | separately. |
| 75 | </p> |
| 76 | |
| 77 | <p> |
| 78 | <b>Abstraction:</b> All APIs must use the most general abstractions possible. For instance |
| 79 | reading binary data should rely on the <code>java.io.InputStream</code> interface, not |
| 80 | on a <code>java.io.File</code> object. |
| 81 | </p> |
| 82 | |
| 83 | <p> |
| 84 | <b>System Dependencies:</b> Avoid any dependencies to the local file system, network |
| 85 | resources, threads, processes etc. |
| 86 | </p> |
| 87 | |
| 88 | <h2>Test Driven Development</h2> |
| 89 | |
| 90 | <p> |
| 91 | All code added to JaCoCo should have corresponding JUnit test cases. Ideally tests |
| 92 | are developed before or along with the actual implementation: |
| 93 | </p> |
| 94 | |
| 95 | <ul> |
| 96 | <li>Every new feature should be verified by test cases.</li> |
| 97 | <li>Modified behavior should also be reflected by test cases.</li> |
| 98 | <li>Ideally for every reported bug a reproducer is added to the unit tests.</li> |
| 99 | </ul> |
| 100 | |
| 101 | <h2>Keep an Eye on License Issues</h2> |
| 102 | |
| 103 | <p> |
| 104 | All code included with JaCoCo must conform to the EPL license. |
| 105 | </p> |
| 106 | |
| 107 | <ul> |
| 108 | <li> |
| 109 | Every committer and contributor must agree that all code will be published |
| 110 | under EPL. He or she must be the original author and must have the |
| 111 | permission to contribute code to JaCoCo, for example if such a permission |
| 112 | is required by the employer. |
| 113 | </li> |
| 114 | <li> |
| 115 | Every third party content must be enlisted in the corresponding |
| 116 | <code>about.html</code> file along with its license. |
| 117 | </li> |
| 118 | <li> |
| 119 | Every third party content included with the JaCoCo distribution must be |
| 120 | enlisted in the <code>org.jacoco.doc/docroot/doc/license.html</code> file |
| 121 | and the corresponding <code>about.html</code> file along with its license. |
| 122 | </li> |
| 123 | <li> |
| 124 | Every source file (Java, Build Script, DTD) must have a |
| 125 | <a href="http://www.eclipse.org/legal/copyrightandlicensenotice.php">EPL |
| 126 | license notice</a>. The initial contributor should be listed. In case of |
| 127 | significant changes or additions additional contributors should also |
| 128 | be listed. |
| 129 | </li> |
