Java Testing Style

Default Heuristics

• Prefer FIRST: Fast, Isolated, Repeatable, Self-Verifying, and Timely.
• Prefer OTAO: one test covers one behavior and ideally has one reason to fail. Multiple assertions are fine when they verify that same behavior.
• Name unit tests given{SomeCondition}_should{ExpectedResult}.
• Name the observed value actual.
• Use JUnit Jupiter assertions from org.junit.jupiter.api.Assertions; do not introduce AssertJ unless the project requires it or the user asks for it.
• Keep assertions simple and readable.
