+/**
+ * Uses combinatorics to test the behavior of a test function by comparing it to
+ * the expected behavior (defined by a reference function) for a large number of
+ * possible input values.
+ *
+ * First generates test cases by taking the cartesian product of the given
+ * values. Each test case is a set of N values corresponding to the N arguments
+ * for the test func and the reference func. For each test case, first the
+ * reference function will be called to obtain an "expected result", or if the
+ * reference function throws/rejects, an "expected error". Next, the test
+ * function will be called to obtain an "actual result", or if the test function
+ * throws/rejects, an "actual error". Each test case passes if at least one of
+ * the following conditions is met:
+ *
+ * 1) Neither the reference function or the test function throw and the
+ * "expected result" equals the "actual result".
+ *
+ * 2) Both the reference function and the test function throw and the "actual
+ * error" message *contains* the "expected error" message.
+ *
+ * The first test case which does not meet one of these conditions will cause
+ * the entire test to fail and this function will throw/reject.
+ *
+ * @param referenceFuncAsync a reference function implemented in pure
+ * JavaScript/TypeScript which accepts N arguments and returns the "expected
+ * result" or "expected error" for a given test case.
+ * @param testFuncAsync a test function which, e.g., makes a call or sends a
+ * transaction to a contract. It accepts the same N arguments returns the
+ * "actual result" or "actual error" for a given test case.
+ * @param values an array of N arrays. Each inner array is a set of possible
+ * values which are passed into both the reference function and the test
+ * function.
+ * @return A Promise that resolves if the test passes and rejects if the test
+ * fails, according to the rules described above.
