  03 Hurdles in front GPSpositioning systems can accurately detect an object in normal conditions. However, it can show great deal of fluctuations when there is a barrier involved. Above all that if there an adverse weather conditions GPS signals can get affected too. Since huge amount of data is transferred between client and server side applications performance of the apps can be gravely affected This bottleneck comes from the limitation of both hardware and software of the mobile device. Network connection is one of the reasons that makes the location based service device’s vperformance go up and down. Moreover, GPS handles a huge amount of data and it solely work on integration with satellites extensive testing is required. Moreover, hardware integrated with it and devices which GPS work have the chances to produce varied result. Thus making testing on the most important process in the production of such location based software. www.testbytes.net/

  07 Main focus pointsin testing Functionality: in the case of a location based application functionality test will differ from that of a normal one. We tested the app to find out how themobileappbehaves to input contexts, validate location query and data. Often, black-box testing techniques such as equivalence partitioning and decision-table- based methods were conducted to ensure functional perfection of the software. When new features, location etc. Are added to the app, regression testing was done to spot anomalies. Network Connectivity Testing: steady and stable network connectivity is a must for any tool that’s being put to use for location based activities. To get a real picture of mobile apps behaviour and performance network testing has to be done in different network context. Besides all these, accuracy of positioning system and bandwidth are cardinal factor of any location based app. www.testbytes.net/

  08 Usability Testing: Usability ofany software is essential for its survival. It is ensured through users’ participation and their expectations on satisfaction, learnability, and efficacy of the app. From a user perspective usability can be evaluated by interface design, ease of access, swiftnessand reliability of the app in response to requested location service. Tomeettheexpectation of auser combination of various field as well as lab tests has to be performed on the app. Field based testing has of more importance in a location based application as it is the scenario in which a user is directly engaged to the application. Scalability Testing: In testing LBS, a test engineer should ensure scalability of resources and services of the entire system. Resources including database, application servers, positioning systems and networkserviceshastobecheckedcontinuously. Consideringthehuge increase in mobilephone user’s tests like this has to be conducted. Measuring scalability bottlenecks can be integrated into a test environment where hardware and software resources are analyzed, and the change of the app behaviour is monitored and reported for a further test plan. To achieve these goals, load and stress testing are proper solutions www.testbytes.net/

  09 Security and Privacy: Securityis the biggest concern ofany location based application and the potential danger of revealing your location can happen. To overcome this, testcases has to be designed that has a secure transmission protocol. Performance: Be it any app performance is vital. In the case of a location based application there are other factors that will come to play. This was kept in mindwhileperformanceoftheappwas tested. www.testbytes.net/

  11 GPS module testingprocedure • Always testing on physical devices is better, owing to that we used mobile phones from various vendors for testing • Devices and hardware used for testing are carefully picked after confirmation from previous tests • We have always made sure tests are conducted on regular interval as per our system configuration • We have developed in-house testing tools for both bug tracking and report generation • For field testing a digital perimeter is set and vehicles with live tracking apps are set to travel. In short, lot of live trip data is collected for analysis • Since Mobile phones work on internal GPS. Satellite catch accuracy, frequency and strength was evaluated • Various geographical locations and barriers are selected to measure the signal quality • Successive signals are compared for anomalies • Signal strength and vehicle speed is also compared • There are plenty of GPS hardware out there in the market made by multiple vendors for accurate tracking and other purposes. We make use of the most widely used ones to collect varied data to conclude which one is the best. • Historic trip data is fed to the system at regular intervals to check anomalies • If there is any, fine tuning will be done and the tests will be repeated www.testbytes.net/
• 13.
  • To artificiallygenerate GPS signals we have developed in-house simulators that feed the system with artificial signals at different intervals. • Various signals such as 2G, 3G and 4G are fed to the system to find out how it responds. • Since location is changing continuously in vehicle signal strength and type can also change test cases designed for such cases are done by considering various factors such as wireless network environments, position environment, speed, location relation between moving object and mobile users etc. • Data that we gained using real-time vehicle travel and simulators are fed to the system and a in-house software is integrated to it so that feeding data can be auto-repeat • Results and bug tracking report are sent to customers at recommended intervals • Regular communication between client, developers and testers were carried through 12www.testbytes.net/

  13 Testing using JMeter Jmeteris an impeccable tool when for load testing and performance testing of any software. Here is how we used the tool in testing the application, • Vehicle tracking and trip creation environment were artificially simulated using TCP sampler by using GSM signals • Values such as latitude and longitude were parsed in GSM signals with the help of various Jmeter elements such as Timers, processor, configuration elements etc. • We used "Thread group" component for hit certain amount of signals on the server with particular time duration with respect to loop count(s) • Load test report with vivid graphical representation were created using listeners • Clients can see various results in form of graphical representation, summary reports, result tree etc. www.testbytes.net/
