From my data-driven Game of Life code from Global Day of CodeRetreat

dead_cell_assertion

// Full code base:
// https://github.com/JeffHoover/Data-Driven-GoL

// Hard to read bare assertion:
// Assert.AreEqual(State.DEAD, _ruleEngine.GetNextCellState(State.DEAD, numNeighbors));

// Easier to read helper method:
Assert_Dead_Cell_Stays_Dead_With_X_Neighbors(numNeighbors));

// Suggested by @mattslavicek - loses important information about cell starting state
// AssertCellEvolvesAndRemainsDead(int numNeighbors));

// Another hard-to-read bare assertion:
// Assert.AreEqual(State.DEAD, _ruleEngine.GetNextCellState(State.DEAD, numNeighbors));

// Maybe:
// AssertDeadCellEvolvesAndStaysDead(int numNeighbors));
