// --------------- Test Class --------------- //

class ConversionsTests : public CxxTest::TestSuite {

	public:

	// Shared data elements go here.
	double delta_percent;         // percentage difference for floating-point comparisons in TS_ASSERT_DELTA

	// --------------- Fixtures --------------- //

	// Define a test fixture (some initial state that several tests share)
	// In CxxTest, setUp()/tearDown() are executed around each test case. If you need a fixture on the test
	// suite level, i.e. something that gets constructed once before all the tests in the test suite are run,
	// suites have to be dynamically created. See CxxTest sample directory for example.

	// Shared initialization goes here.
	void setUp() {
		delta_percent = 0.0001;
	}

	// Shared finalization goes here.
	void tearDown() {
	}
