Validation is a process of comparing the model and its behavior to the real system and its behavior. Calibration is the iterative process of comparing the model with real system, revising the model if necessary, comparing again, until a model is accepted (validated). Three-step approach in the validation process.

Client-side validation is faster than server-side because, the validation takes place on client side (on browser) and the networking time from client to server is saved. On the other hand, server-side validation is done on the web server.

Test and assessment are used interchangeably, but they do mean something different. A test is a “product” that measures a particular behavior or set of objectives. Meanwhile assessment is seen as a procedure instead of a product. Assessment is used during and after the instruction has taken place.

A Build Lifecycle is Made Up of Phases validate - validate the project is correct and all necessary information is available. compile - compile the source code of the project. test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed.

What's the difference between reliability and validity? ... Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

What are the key differences between validation testing goals and acceptance testing goals? Acceptance testing goals: are designed to help the customer validate all of the requirements. Acceptance testing is used when the software is made for a customer. List four types of systems tests.

Statement coverage: It ensures that each line of source code has been executed and tested. Decision coverage: It assures that every decision (true/false) in the source code has been executed and tested. Path coverage: Here we ensure that every possible route through a given part of the code is executed and tested.

Data verification is a way of ensuring the user types in what he or she intends, in other words, to make sure the user does not make a mistake when inputting data. ... Validation is about checking the input data to ensure it conforms with the data requirements of the system to avoid data errors.

What is the difference between functional and structural testing ? Structural is a “white box” testing and based on the algorithm or code. Functional testing is a “black box” (behavioral) testing where the tester verifies the functional specification.

Static testing is about the prevention of defects whereas Dynamic testing is about finding and fixing the defects. Static testing does the verification process while Dynamic testing does the validation process. Static testing is performed before compilation whereas Dynamic testing is performed after compilation.
