-/**
- * 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.
