Genislab TechnologiesTest implementation is the practice of organizing and prioritizing tests. This is carried out by Test Analysts who implement the test designs as real test cases, test processes and test data. [Read more…] about What is Test Implementation?

What are the risks or disadvantages of using the testing tools?
Although there are many benefits that can be achieved by using tools to support testing activities, but there are also many risks that are associated with it when tool support for testing is introduced and used.
Risks include:
- Unrealistic expectations from the tool: Unrealistic expectations may be one of the greatest risks to success with tools. The tools are just software and we all know that there are many problems associated with any kind of software. It is very important to have clear and realistic objectives for what the tool can do.

What is Branch Coverage or Decision Coverage? Its advantages and disadvantages
- Branch coverage is also known as Decision coverage or all-edges coverage.
- It covers both the true and false conditions unlikely the statement coverage.

What is Big Bang integration testing?
In Big Bang integration testing all components or modules are integrated simultaneously, after which everything is tested as a whole.
- In this approach individual modules are not integrated until and unless all the modules are ready.
- In Big Bang integration testing all the modules are integrated without performing any integration testing and then it’s executed to know whether all the integrated modules are working fine or not.
- This approach is generally executed by those developers who follows the ‘Run it and see’ approach.
- Because of integrating everything at one time if any failures occurs then it become very difficult for the programmers to know the root cause of that failure.
- In case any bug arises then the developers has to detach the integrated modules in order to find the actual cause of the bug.
Below is the image of the big bang integration testing:
Suppose a system consists of four modules as displayed in the diagram above. In big bang integration all the four modules ‘Module A, Module B, Module C and Module D’ are integrated simultaneously and then the testing is performed. Hence in this approach no individual integration testing is performed because of which the chances of critical failures increases.
Advantage of Big Bang Integration:
- Big Bang testing has the advantage that everything is finished before integration testing starts.
Disadvantages of Big Bang Integration:
- The major disadvantage is that in general it is very time consuming
- It is very difficult to trace the cause of failures because of this late integration.
- The chances of having critical failures are more because of integrating all the components together at same time.
- If any bug is found then it is very difficult to detach all the modules in order to find out the root cause of it.
- There is high probability of occurrence of the critical bugs in the production environment
What is Prototype model- advantages, disadvantages and when to use it?
The basic idea in Prototype model is that instead of freezing the requirements before a design or coding can proceed, a throwaway prototype is built to understand the requirements. This prototype is developed based on the currently known requirements. Prototype model is a software development model. By using this prototype, the client can get an “actual feel” of the system, since the interactions with prototype can enable the client to better understand the requirements of the desired system.
