PeriodicTableTests.java

//
// JUnit tests for periodic table (elements) classification
// - tests beginning with "BB" are black-box average case tests
//   for some equivalence classes, but not all. The zero and 
//   hydrogen tests could also be considered boundary tests.
// - tests beginning with "MCDC" are tests created from the 
//   MC/DC analysis in the "pairsandtests.txt" file, for just
//   one if statement in the code.
// - always remember that no matter what method was used to 
//   create a test (BB, WB-statement, WB-branch, WB-MCDC),
//   the way to determine the correct outcome of a test is
//   by using the specification of what the code is supposed
//   to do!
