SDLC Testing Online Test, SDLC online practice test, SDLC quiz

testing effort estimation is calculated on the basis of no. of test cases and coverage criteria. By default the testing effort is 50 %.
Therefore, 50% is a correct answer.

In the SDLC, Design phase has 2 types: Technical architecture is describing the design of the hardware and software components and Functional specification describes the overall requirement or function of the system.

Therefore, two is the correct answer.

Ada language is used to develop the long term projects. It supports many concepts of software engineering as Generic Package for reuse the software component.
Information hiding: hide the Implementation details of the package.
Abstraction: abstraction package for managing the complexity of the project.
Therefore, all of these are correct answer.

Content coupling is control the flow of the module and logical cohesion that is used for grouping the part of a module on the basis of logical category and stamp coupling is preferred than functional coupling.

Therefore, all of these are correct answer.

Control structure defines the sequence of all the statements that are executed. The control structure includes: Sequence execution, Loop means iteration as for-loop, two way decisions as if-else, Exception Statement as try and catch and rendezvous statements.

Therefore, all of these are correct answer.

LOC: is a software metric that is used to calculate the size of the program by calculating the number of lines.
Execution Speed: Execution speed is used to calculate the speed of execution at a specified time.
Defect Report: It is a report that is used to define the number of defect find in the overall build.

Therefore, all of these are correct.

This model is used for calculating the cost estimation and a program size of the develop product or software.
Efforts Applied E = a * (KDL) 6 equation is used to calculate the efforts applied to the software.

Therefore, option A is correct.

Data coupling: Data coupling is the process when two modules are sharing same data from one parameter.
Stamp coupling: Stamp coupling is the process when two modules are sharing composite data structure(needed one field from many fields) .

Control coupling: control coupling is the process which is used to control the flow of one module or the order of the execution of instruction by using another module.
Routine call coupling: Routine call coupling is not related to the SDLC.

Therefore, Control coupling is correct answer.

Product revision is the process to do some action for revision or to verify the requirement, source code, function or program. The product revision is used to maintain the program, source code etc.
The product revision is also related to the testability to review the program and it is also flexible because we may easily change in the action of revision. But it can’t be re usability.

Therefore, reusability is correct answer.

Product transition is the process that is used to deliver lower system product and higher system product for the integration process. The product transition process is Reusability, Probability and interoperability.

Structural testing and glass box testing are the same that is used to evaluate the source code of the program. It is low level testing.
Functional testing is high level testing. It is a Black box technique that is used to test the system by executing the test cases and compares the actual and expected results.

Therefore, functional testing is a high level testing.

Automated recovery is used when any system gets effected by any fault or bug, then automated recovery process automatically restart the system, recover the data of the system and check for the system re-initialization.

Therefore, all of these options are correct.

Drill and practice program is education software that provides a practice phase for learning the facts through reputation and allows students to work at their own pace while focusing on skills.

Therefore, Both A and B are correct option.

Verification is the internal resources as review, walkthrough, Inspection that is used to determine the product is meeting the specified requirement or not and validation is external resource as testing that is used to determine the product is meeting the client requirement or not.

Therefore, option A is correct.

Iterative model is also known as incremental model. In iterative model the delivery of software is divided into multiple builds version by version. RAD, incremental and spiral model are also developed product in multiple build by adding new functionality or changes.

Therefore, V model is not related to the iterative model.

Attack resistance is a process that is used to resist or secure the system from attack. Attack tolerance is a process that is used to tolerate the attack in the system. So by using these processes we produce an effective architectural and effective design decision.

Therefore, option A is correct.

Decision table is used to represent the combination of input values with their output and action. Decision table is divided into 4 parts: Entry portion, Stub portion, Action portion and condition portion.

Therefore, Driver portion is a correct answer.

Coupling and cohesion are similar. Coupling is used for indicating the dependency between components or program and cohesion is used for indicating the relationship between the modules. Both are using cause effect graph for the representation of the relationship or dependency between modules.

Therefore, a cause – effect graph is correct answer.

Requirement engineering is the process of collecting, analyzing, documenting and maintaining the software requirement. Requirement elicitation is the process of collecting requirement from user, requirement analysis is the process of analysis requirement and requirement documentation is the process of converting user requirement into a formal document.

And requirement design is the process of converting requirement into the design.

Therefore, requirement design is not related to requirement engineering.

V model and iterative model are always used for the long term projects.
Spiral model is used for high risk projects.
Agile model is a newer model that is used when a project is short term and client requirement is rapidly changing.
Therefore, agile model is the correct answer.

Cyclomatic complexity is software metric that is used to define the complexity of the source code. It is also used to calculate the number of independent paths in the program source code. Cyclomatic complexity is used in Re-engineering, risk management and test planning by calculating the complexity of the program.

Therefore, Reverse Engineering is correct answer.

Condition coverage is also known as predicate Coverage that is used to calculate the percentage of condition outcome
Condition coverage and decision coverage are similar
Predicate coverage or condition coverage is used to verify the execution of a condition statement as if – else, so the result always calculated in true and false or 1 and 0, so it uses Boolean values.

Error guessing testing is based on the experience of the tester, so it doesn’t have any predefined rule.

Therefore, option c is correct.

Spiral model is related to the incremental model, but it also focuses on risk analysis. Spiral model has 4 phases: Planning, Risk analysis, Engineering and evaluation. The production process passes through all these phases in each iteration cycle. If any change occurs, we need to iterate the whole cycle.

Therefore, only option B is satisfied the answer.

Walkthrough, Data flow analysis and inspection are the static analysis techniques with is used to evaluate and verify the system without executing and error guessing is a black box technique that is done by the experience tester.

Therefore, Error Guessing is different from others.

Test Stub: It is a dummy model of a sub module in integration testing that act as temporary replacement for a called module.
Test Driver: It is a dummy model of main module in integration testing that is used to call the function and for passing test data value.
Proxy: It is a server that is not used for calling a function.

Therefore, test driver is a correct answer.

Nullity is the cyclometic number of the graph that is directly calculated by the simple formula Nullity = e-n+k.
E = no of edge, and = number of vertices and k is the number of connected components.

Therefore, option A is correct.

Mutual exclusion is used to avoid the concurrent use of the same resources. But sometimes the problem is occurred in mutual exclusion when process or program is not sharing the same resources.

Therefore, option C is correct.

Disaster Recovery is a process, policy or procedure that is prepared for recovering the system after installation has been disabled by a natural or human disaster.

Therefore, varies in degree between installations.

It is a method for creating backups of file or data of the system those are recently changed or new add since the last backup.

Therefore, Option C is correct.

Trojan horse is a kind of virus that inserts some harmful code inside the programming or data. So any unauthorized user may easily access the system and also affect the system by data loss, crash system etc.
Therefore, Option A is correct.
