Testing Telecom Domain with Sample OSS/BSS Test cases
What is Telecom Testing, and what does it entail?
Telecommunication software testing is characterized as telecom testing. The telecommunications business has relied on the software since the transition to digital and computer networks. Many services in the telecom business, such as routing and switching, VoIP broadband access, and so on, rely on various sorts of software components. Telecom software testing is thus unavoidable.
In testing, what is a domain?
The industry for which the software testing project is built is referred to as a domain. This word is frequently used while discussing software projects or development. The Insurance domain, for example, the Banking domain, the Retail domain, the Telecom domain, and so on.
Typically, domain expert assistance is requested when building any specialized domain project. A domain expert is an expert in his field who may know everything there is to know about a product or application.
Why is it important to test domain knowledge?
Domain expertise is vital for testing any software product, and it comes with its own set of advantages, such as
It reduces the training time.
It helps in quick defect tracking
It gives a good idea of UI features and back-end processing
It gives good hold workflow, business process, and rule
It helps to understand easily the technical technology
An Example of a Telecom Business Process
The following is an example of a typical telecom business procedure.
Telecom Service Provider (TSP) approaches customer
Customer generates inquiry
Customer orders service to TSP
After technical evaluation, implementing of an order takes place
The tracking system tracks the order status if the order implementation stops at any stage, tracks and tries to fix it
After implementation is done, the client starts using the service, the billing starts
Now to support the customer service, the service assurance team works
The software will have applications to support each of these
The Telecom Industry's Business Processes
End-to-end service verification is critical in telecom testing. A thorough understanding of the various business processes is required to ensure efficient testing.
Before designing the test cases, you must first comprehend each level of service delivery ability.
Telecom services are based on either a business support system (IVRs, Call Centers, invoice generation, etc.) or an operation support system (routers, switches, cell towers, etc.).
The following points illustrate which actions are conducted at various levels.
Pre-sales − It manages all sales information, such as discounts, services, and promotions.
Ordering − Making an application for a new connection or disconnecting an existing one
Provisioning − This division is in charge of the physical link between clients and TSP (Telecom Service Provider)
Billing − All billing work is completed in this section.
Assurance of Service − In the event of a failure, this division is in charge of rectifying the situation.
Inventory Control Systems − It is the central store for all data.
Tracking − This division keeps track of the ordering system and order status.
In the Telecom Industry, Life Cycle is being tested
The telecom sector's test lifecycle is comparable to that of any other industry, but with a focus on details. The test lifecycle is depicted below, along with the test artifacts.
Requirement based test artifacts
Feasibility based artifacts
Standard and policy identification based test artifacts
Operation and maintenance considerations related to testing artifacts
System test artifacts (Security, Installation)
Test artifacts for virtual prototype
Special System Testing artifacts (interoperability, disaster recovery)
- Unit test artifacts
- Integration test artifacts
- Quality and performance artifacts
- Regression, load testing, sanity, etc.
- Acceptance test artifacts
- Integration test artifacts
- Quality and performance artifacts
- Functional test artifacts
- Alpha/Beta test artifacts
Protocols used in the Telecom Industry
The most widely used protocols in the telecom business are listed below.
Signaling and Protocols − SIP, ISDN, Codecs, H.323
VoIP technologies − VoIP, IMS, MPLS, ISDN, PSTN
Wireless technologies − GPRS, CDMA, GSM, and UMTS are examples of wireless technology.
Layer 2 Protocols − ARP, STP, L2TP, PPP
Layer 3 Protocols − ICMP, BGP, ISIS, MPLS
Infrastructure/ Security − ATM, TCP/IP, LAN/VLAN, and SSH are examples of infrastructure and security
Types of Testing Performed on Telecom Software
The benefits of Having Domain Expertise
Domain knowledge is essential for each project's testing.
The following is a list of the numerous benefits of having domain knowledge −
Lessens the amount of time spent training
If a tester already has domain knowledge, they will only need little training, which will save the project money and time.
Any firm with domain knowledge will be more productive since testers with domain knowledge can quickly grasp any problem particular to their domain expertise and deliver the exact answer to the problem, cutting down on analysis time.
This will boost both the project's and the organization's productivity.
Solid knowledge of the user interface and back-end processes
A tester with in-depth topic knowledge can recommend an application's user interface (UI) from the perspective of the end-user. They can also identify issues early in the testing process thanks to their expertise in the back-end system.
If a tester has domain knowledge, they can go outside the box and develop novel test cases that raise valid issues about an application's present workflow.
Familiarity with the domain's technical terms
Typically, a developer will use technical jargon throughout a conversation, therefore domain expertise will be beneficial to a tester during such conversations. This will be beneficial to the testing group as well.
If a tester has domain knowledge, he or she can analyze the test cases technically and proposed technical adjustments to the test case flow as required by the business.
Knowledge of Business Procedures and Rules
Domain-savvy testers can join in discussions with the business and development teams. When representing a business in front of a client, their knowledge will be crucial. Such testers can immediately discover flaws in the requirement document since they have a thorough understanding of the domain processes and standards.
A Valuable Contributor to the Company
Testers with subject knowledge might serve as mentors to newcomers to the company. This saves money for the project and the organization, which would otherwise have to hire a specific coach.
Telecom Testing Sample TestCases
In Telecom Testing, the following tests must be considered.
|Various Telecom Testing||Testing activities in Telecom|
The telecom service is a very broad field that includes a variety of components such as cables, networks, signals, protocols, and so on, and their testing necessitates a wide range of testing techniques. The testing techniques and strategy used are heavily influenced by the component of telecom being tested.
The test requirement, scope, test scenarios, testing methodology, testing tools, and so on vary depending on the type of testing involved, such as VoIP protocol testing or CDMA wireless device testing. The lesson provides a basic yet comprehensive explanation of how telecom testing can be carried out, as well as a discussion of various telecom testing prospects.
