MOBILE TESTING & SIP COMMUNICATION
Mobile testing is the testing process that is conducted to evaluate the proper functioning, performance, and usability of mobile applications or websites. These tests are conducted to ensure that applications operate seamlessly and effectively on different mobile devices and operating systems.
The importance of mobile testing can be realized in 5 major headlines considered in mobile software development as follows:
- User Satisfaction: A seamless mobile experience increases user satisfaction.
- Application Security: Detects security vulnerabilities and protects user data.
- Performance Improvement: Mobile testing evaluates the performance of the app or website and ensures improvements are made where necessary.
- Compatibility on Various Devices: Testing on different devices, screen sizes, and operating systems ensures that the application appeals to a wide range of users.
- Early Error Detection: Correcting errors detected at an early stage reduces development costs and speeds up the process.
Mobile Testing Processes:
The mobile testing process addresses critical elements such as user experience, device compatibility, performance optimization, security, and software quality. It ensures the application runs smoothly on different devices and screen sizes and detects and fixes performance errors. It also addresses security vulnerabilities, protects user data, and improves the overall quality of the software.
Detecting errors at early stages accelerates the development process and provides a competitive advantage. It allows continuous improvement by evaluating user feedback. This process ensures that mobile applications successfully meet user expectations and stand out from the competition.
AUTOMATED TESTING, MANUAL TESTING, AND RELEVANT USE CASES
Manual testing is an approach based on a test expert or user manually executing test scenarios.
• It is used to evaluate user experience and test the user interface.
• Used to test graphical errors.
• Simulating user scenarios, checking edge cases and understanding user feedback
On the other hand, automated testing is the process of evaluating the functionality, performance, or other features of software or applications via scripts or programs without or with minimal manual labor.
• Faster and more efficient results.
• Low cost usage.
• Continuous testing of software.

Mobile Testing Among Communication-Style Applications
Why is a special approach needed to test the audio and video communication capabilities of mobile applications? This is because audio and visual communication has a diverse structure that significantly affects the testing processes. The hardware selection, Operating System choice, application interface design, and overall application experience can cause structural differences that significantly affect the testing process.
SIP and VoIP Tests
SIP (Session Initiation Protocol) is a communication protocol that manages the initiation, modification, and termination of sessions in audio and video communication. VoIP (Voice over Internet Protocol) is a technology that provides voice communications over the Internet instead of traditional phone lines.
SIP Basic Call Flow
As seen in the figure, two people far away from each other will make a phone call. When Alice sends a call request to Bob, the server finds Bob and sends her a phone invitation request. (“INVITE” shows this)
As soon as the invitation goes from the server to Bob, the 180 Ringing code you see in the figure is returned.
Simultaneously, 100 Trying codes are returned to Alice. This means that the Server sent an invitation to Bob and is waiting for Bob to accept the invitation.
As soon as Bob accepts the call invitation, a 200 OK code is sent. After the invitation is accepted, the two begin to meet and the server is no longer available. (“ACK” means that the two have started a conversation.)
RTP (Real-Time Transport Protocol) and RTSP (Real Time Streaming Protocol) indicate a media flow between them.
After the phone calls are finished, the BYE code is sent. The phone call ends with the code 200 OK.
SIP ERROR CODES
400 — Bad Request
403 — Forbidden
404 — Not Found
500 — Internal Server Error
