pyTooling's test report format. It differs from JUnit XML in two ways that JUnit cannot express: test suites nest, instead of being flattened into a dotted 'classname'; and every item carries four distinct names - an identifier, a title, a summary and a description - instead of one name and a bag of properties. The outcome of a testcase. The three names an item carries besides its identifier. The identifier is the 'name' attribute. A short label, written for a reader rather than for Python. The first paragraph of the item's doc-string. The item's doc-string, with its line breaks preserved. Why the testcase did not pass: the failure, error or skip reason. The test runner's own identifier for this testcase, so a reader of the report can re-run it. The results of one test session.
