[shrinkwrap-issues] [JBoss JIRA] (SHRINKDESC-89) Improve test code readability by introducing assertion DSL

Improve test code readability by introducing assertion DSL ---------------------------------------------------------- Key: SHRINKDESC-89 URL: https://issues.jboss.org/browse/SHRINKDESC-89 Project: ShrinkWrap Descriptors Issue Type: Task Components: test Affects Versions: 1.1.0-alpha-5 Reporter: Bartosz Majsak Assignee: Michal Matloka Priority: Optional Labels: testing Improving tests assertion might bring few benefits for us, such as: * more concise tests focused on the functionality * better readability and understanding of the tests (and the way how our tool works in general [which might be really handy for newcomers]), also by using domain-specific assertions * easier maintenance For instance for Node assertions we could have: {code} assertThat(root.getChildren()).containsOnly(CHILD_1, CHILD_2) {code} or even something more fancy {code} assertThat(node).isAccessibleFrom(otherNode) {code} Two options worth considering are: * [Hamcrest|http://code.google.com/p/hamcrest/] (bundled with JUnit as of 4.4) * [FEST-Assert|http://docs.codehaus.org/display/FEST/Fluent+Assertions+Module] I would rather go with the latter. Its' fluent interface DSL is somehow easier to use in tests.
