The scope of the acquisition "ByRange" is different from the FabricNodeSDK.

The scope of the data to be acquired in getStateByRange is different from the FabricNodeSDK.

FabricNodeSDK
getStateByRange(startKey, endKey)
Parameters:
Name Type Description
startKey string State variable key as the start of the key range (inclusive)
endKey string State variable key as the end of the key range (exclusive)

howabout, fabric-mock-stub is ,,
startKey → inclusive
endKey → inclusive

getStateByRange(startKey: string, endKey: string): Promise<Iterators.StateQueryIterator> {

    const items: Iterators.KV[] = Object.keys(this.state)
        .filter((k: string) => {
            const comp1 = Helpers.strcmp(k, startKey);
            const comp2 = Helpers.strcmp(k, endKey);

            return (comp1 >= 0 && comp2 <= 0) || (startKey == '' && endKey == '');  // " comp2 <= 0 " should be "comp2 < 0"  
        })
        .map((k: string) => new MockKeyValue(k, this.state[k]));

    return Promise.resolve(new MockStateQueryIterator(items, this.txID));

}

Furthermore, getPrivateDataByRange contains the same bug.
