Software Testing Types: Black box testing – Internal system design is not considered in this type of testing. Tests are based on requirements and functionality. Software testing is a process of executing a program or application with the intent of finding the software bugs.

What is Cyclomatic complexity? Black box testingb) White box testingc) Yellow box testingd) Green box testing. View Answer Answer: b. Explanation: Cyclomatic complexity measures the amount of decision logic in the program module. Cyclomatic complexity gives the minimum number of paths that can generate all possible paths through the module. Lower and upper limits are present in which chart?

Run chartb) Bar chartc) Control chartd) None of the mentioned. View Answer Answer: a. Explanation: A run chart is used to monitor the behavior of a variable over time for a process or system. Run charts graphically display cycles, trends, shifts, or non- random patterns in behavior over time. It contains lower and upper limits.

Software Testing Methods - Learn Software Testing in simple and easy steps starting from its Overview, Myths, QA, QC & Testing, ISO Standards, Types of Testing.

Maintenance testing is performed using which methodology? Retestingb) Sanity testingc) Breadth test and depth testd) Confirmation testing.

View Answer Answer: c. Explanation: Maintenance Testing is done on the already deployed software. The deployed software needs to be enhanced, changed or migrated to other hardware. The Testing done during this enhancement, change and migration cycle is known as maintenance testing. White Box techniques are also classified asa) Design based testingb) Structural testingc) Error guessing technique. View Answer Answer: b. Explanation: The structural testing is the testing of the structure of the system or component.

Structural testing is often referred to as . Exhaustive testing isa) always possibleb) practically possiblec) impractical but possibled) impractical and impossible. View Answer Answer: c.

Explanation: Exhaustive testing is the testing where we execute single test case for multiple test data. It means if we are using single test case for different product or module under manual testing. Which of the following is/are White box technique? Statement Testingb) Decision Testingc) Condition Coveraged) All of these. View Answer Answer: d. Explanation: Statement testing, decision testing, condition coverage all of them uses white box technique.

What are the various Testing Levels? Unit Testingb) System Testingc) Integration Testingd) All of the mentioned. View Answer Answer: d. Explanation: Unit, system, integration testing all of them are levels in testing. Boundary value analysis belong to? White Box Testingb) Black Box Testing.

View Answer Answer: b. Explanation: Boundary value analysis is based on testing at the boundaries between partitions and checks the output with expected output. Alpha testing is done ata) Developer’s endb) User’s end. View Answer Answer: a. Explanation: Alpha testing takes place at the developer’s end. 7 Pasos Para Desarrollar Un Software.

Developers observe the users and note problems. Alpha testing is testing of an application when development is about to complete. Minor design changes can still be made as a result of alpha testing.
