Mixed Selectors ^^^^^ **Definition:** * The problem of mixing up all the methods of a test-class is that it is harder to allocate and differentiate accessors, xtures, utilities and test-methods. By putting each type of method into a different method category, especially strictly separating test-methods from other methods we get a better structure of the test-class. A better and cleaner structure helps in understanding the test-suite, the xtures and all the test-methods. **References:** .. admonition:: Quality attributes * :octicon:`file-code;1em` - Code Example * :octicon:`comment-discussion;1em` - Cause and Effect * :octicon:`graph;1em` - Frequency * :octicon:`sync;1em` - Refactoring * `Assessing test quality ‐ TestLint `_ :octicon:`comment-discussion;1em` * `Automatic generation of smell-free unit tests `_ :octicon:`comment-discussion;1em` * `Rule-based Assessment of Test Quality `_ :octicon:`graph;1em` * `Test Smell Detection Tools: A Systematic Mapping Study `_
