Steps of Bottom-Up Integration Testing
Following are the steps that are needed to be followed during the processing :
- Clusters are formed by merging or combining low-level modules or elements. These clusters are also known as builds that are responsible for performing certain secondary or subsidiary functions of software.
- It is important to write a control program for testing. These control programs are also known as drivers or high-level modules. It simply coordinates the input and output of a test case.
- Testing is done on the entire build or cluster containing low-level modules.
- lastly, the control program or drivers or high-level modules are removed and clusters are integrated by moving upward from bottom to top in the program structure with the help of control flow.
Steps in Bottom Up Integration Testing
Bottom-up Testing is a type of incremental integration testing approach in which testing is done by integrating or joining two or more modules by moving upward from bottom to top through the control flow of the architecture structure. In these, low-level modules are tested first, and then high-level modules are tested. This type of testing or approach is also known as inductive reasoning and is used as a synthesis synonym in many cases. Bottom-up testing is user-friendly testing and results in an increase in overall software development. This testing results in high success rates with long-lasting results.
