-/**
- * Tests the behavior of a test function by comparing it to the expected
- * behavior (defined by a reference function).
- *
- * 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". The test 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.
- *
- * @param referenceFuncAsync a reference function implemented in pure
- * JavaScript/TypeScript which accepts N arguments and returns the "expected
- * result" or throws/rejects with the "expected error".
- * @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 throws/rejects with the "actual error".
- * @param values an array of N values, where each value corresponds in-order to
- * an argument to both the test function and the reference function.
- * @return A Promise that resolves if the test passes and rejects if the test
- * fails, according to the rules described above.
