Find a Graph and Cover It n Tailored to: The state of the program must be incorrect Propagation: External, incorrect behavior with respect to the requirements or other description of the expected behavior Faults in software are design mistakes and will always exist. What should we do during testing?

Testing is a mental discipline that helps all IT professionals develop higher quality software. Sets policy, organizes team, interfaces with development, chooses criteria, decides how much automation is needed, … n Test maintenance: Program Managers often say: My presentations Profile Feedback Log out. To make this website work, we log user data and share it with processors.
How easy it is to provide a program with the needed inputs, in terms of values, operations, and behaviors —Easy to control software with inputs from keyboards —Inputs from hardware sensors or distributed software is harder —Data abstraction reduces controllability and observability.
Graph Coverage — Data Flow 6 5 3 2 17 4 This graph contains: Ch 4 The Process page 1CS Building Software is Difficult often delivered late often over budget always with errors must be a custom solution complexity. Failure is defined as different output from the original program 4.

Values needed to terminate the program or otherwise return it to a stable state n Executable Test Script: How easy it is to observe the behavior of a ammanh in terms of its outputs, effects on the environment and other hardware and software components —Software that affects hardware devices, databases, or remote files have low observability n Software Controllability: We are in the middle of a revolution in how software is tested Research is finally meeting practice.
About project SlidePlayer Terms ammamn Service. Test Automation Embed test values into executable scripts This is slightly less technical Requires knowledge of programming Requires very little theory Often requires solutions to difficult problems related to observability and controllability Can be boring for test designers Programming is out of reach for many domain experts Who is responsible for determining and embedding the expected outputs?
Symantec says that most security vulnerabilities are due to faulty software n Stronger testing could solve most of these problems Introduction to Software Testing Ch 1www. Introduction to Software Testing Chapter 2. About project SlidePlayer Terms of Service. A test criterion C1 subsumes C2 if and only if every set of test cases that satisfies criterion C1 also satisfies C2 n Must be true for every set of test cases n Example: A collection of rules and a process that define test requirements Cover every statement Cover every functional requirement Test Requirements: Introduction to Software Testing Chapter 2.
Is the iffutt acceptable to the user? Directly generate test values to satisfy the criterion often assumed by the research community most obvious way to use criteria very hard without automated tools 2. Is a subway system correct? Test the overall functionality of the system n Module testing: The location or locations in the program that contain the fault must be reached 2.
MicroSteff — big software system for the mac V. Software testing terms 3.
Test Evaluation Evaluate results of testing, report to developers This is much harder than it may seem Requires knowledge of: Test each class, file, module, component Integration testing: Copyright Prentice-Hall, Inc.
If a test set has covered every branch in a program satisfied the branch criterionthen the test set is guaranteed to also have covered every statement. A procedure that decides whether a given set of test values satisfies a criterion n Both problems are provably undecidable for most criteria n It is possible to recognize whether test cases satisfy a criterion far more often than it is possible to generate tests that satisfy the criterion n Coverage analysis tools are quite plentiful.
Amman make this website work, we log user data and share it with processors. Define a model of the software, then find ways to cover it Testing researchers have defined dozens offugt criteria, but they are all really just a few criteria on four types of structures …. The location or locations in the program that contain the fault must be reached Infection: Test how modules interact with each other n System testing: Now we know why and what …. Auth with social network: The result that will be produced when executing the test if the program satisfies it intended behavior.
Usability of tools 4. A static defect in the software n Software Error: How do we get to this future of testing? Test each unit method individually. Why do we test? Auth with social network:
