Difference Between Top-down and bottom-up Integration Testing
In this post, we will understand the difference between top-down integration testing and bottom-up integration testing −Top-down Integration TestingIt is also known as incremental integration testing.The higher level modules are first tested after which the lower level modules are tested.Once it is done, they are integrated.The higher level modules are the main modules and the lower level modules are the submodules.It uses stubs to simulate the sub-modules.If the sub-module hasn’t been fully developed, the stub acts like a replacement to it.It is useful in cases where significant defect occurs at the top of the program.The main module is designed first ...
Read MoreDifference Between Fuzzy Set and Crisp Set
In this post, we will understand the difference between fuzzy set and crisp set −Fuzzy SetIt is understood using vague properties.Fuzzy set can have a progressive transition among many degrees of membership.They are generally used in fuzzy controllers.The elements have the ability to be partially included in the set.They are based on infinite-valued logic.They exhibit gradual membership degrees.There is an uncertainty about the set boundaries.Crisp SetIt can be understood using precise and certain characteristics.Here, the transition is sudden, and well defined, not gradual.The element can either be a member of a set or not, no partial ability given.It has a ...
Read MoreDifference Between Informed and Uninformed Search
In this post, we will understand the difference between informed search and uninformed search −Informed SearchThey contain information on goal state.It helps search efficiently.The information is obtained by a function that helps estimate how close a current state is, to the goal state.Examples of informed search include greedy search and graph search.It uses the knowledge in the process of searching.It helps find the solution quickly.It may or may not be complete.It is inexpensive.It consumes less time.It gives the direction about the solution.It is less lengthy to implement.Uninformed SearchThey don’t have any additional information.The information is only provided in the problem ...

Read MoreDifference Between Waterfall Model and Spiral Model
In this post, we will understand the difference between waterfall model and spiral model −Waterfall ModelIt works in sequential method.The errors and risks are identified and rectified after the stages are completed.It is generally used by customers.It can be used with small projects.The requirements and early stage planning is important and required.It is not flexible.It is difficult to make changes in a waterfall model.It involves a high amount of risk.It is comparatively less expensive.Following is the representation of Waterfall Model −Spiral ModelIt works in evolutionary method.The errors and risks are identified and rectified before the stages are complete.It is generally ...
Read MoreDifference Between Manual and Automated Testing
In this post, we will understand the difference between manual and automated testing −Automation TestingIt uses automation tools to execute the test cases.It is fast in comparison to a manual approach.It doesn’t allow random testing to be performed.The initial investment is high.The return on investment is better in the long run.It is reliable.It is performed by tools and scripts.There is no testing fatigue in it.Even for a trivial change, automated test scripts have to be modified.It is expensive.All the stakeholders can login to the automation system and check the results of execution.It doesn’t involve human; hence it can’t assure being ...
Read MoreDifference Between Test Plan and Test Strategy
In this post, we will understand the difference between test plan and test strategy −Test PlanIt is a document prepared for a software project that defines the approach, scope, and intensity required for software testing.It can be changed.It happens independently.It describes the details.It is only done by the test administrator or test manager.It is generally utilized at the project level.Its objective deals with how and when to test the product or system, and who would confirm it.Test StrategyIt is a set of instructions that explain the test design.They also help determine how the test has to be performed.It can’t be ...

Read MoreDifference Between DLP and LCD Projector
In this post, we will understand the difference between DLP and LCD projector −DLP Projector (Digital Light Processing)It is a type of projector that uses a digital micro mirror device.One of the chip has a reflective surface that contains thousands of tiny mirrors that are coordinated with a light source.This helps reflect the digital imagery on to any surface.It provides smooth video.The pixels are less visible.It is more film-like, as on HDTV.It shows the rainbow effect.The intensity of black is amazing.It is portable since it is small and light in weight.The light source could be a standard lamp or an ...
