Real-time testing
Real-time testing is the process of testing real-time computer systems.
Software testing is performed to detect and help correct bugs (errors) in computer software. Testing involves ensuring not only that the software is error-free but that it provides the required functionality to the user. Static and conventional methods of testing can detect bugs, but such techniques may not ensure correct results in real time software systems.
Real-time software systems have strict timing constraints and have a deterministic behavior. These systems have to schedule their tasks such that the timing constraints imposed on them are met.
Conventional static way of analysis is not adequate to deal with such timing constraints, hence additional real-time testing is important.
Test case design for real time testing can be proposed in four steps
As testing of real time systems is becoming more important, there are some tools designed for such testing.
Message Sequence Charts is an internationally accepted standard for capturing requirements. MSC provides a graphical 2-D language often required for collecting requirements through some interaction scenarios.
Specification and Description Language is a standard used for design and analysis. SDL supports the specification of complex software systems and has been extensively applied across a broad array of domains from telecommunications, automation, through to general software development
Testing and Test Control Notation is the only internationally standard testing language. TTCN3 provides a broader applicability, as compared to earlier versions of TTCN, which were primarily focused on OSI protocols only.
These three standards together are used for testing of real time applications. It is necessary that requirements be satisfied with these models and test cases generated must capture the functional and real time information needed to test systems. Also, the changes in the requirements of design and new information about the real time properties of systems should be fed into models so that its impact can be found out.
