It ensures that each integrated subsystem functions as required. Testing is a set of activities which are decided in advance i. Integration testing is defined as a type of testing where software modules are. Proactive an approach in which the test design process is initiated as early as possible in order to find and fix the defects before the build is created. Implementation task either a build or an integration test. Analytical test strategies have in common the use of some formal or informal analytical technique, usually during the requirements and design stages of the project. The effective methods and processes for software and systems integration require disciplined software design and development practices, including test planning, test execution, configuration control, quality, and reporting to management and the customer of the work product being tested inside integration facilities. My friends and i have been struggling to classify exactly what is an integration test. Integration testing is one of the most important test levels and we must understand its approach and objectives.

Im sure developing a good test strategy plan and committing to follow it will definitely improve the testing process and quality of the software. What is test strategy in software testing testlodge blog. Test design as a process is an amalgamation of the test managers experience of similar projects over the years, testers knowledge of the systemfunctionality being tested and prevailing practices in testing at any given point. The purpose of this level of testing is to expose faults in the interaction between integrated units. Modules or components are tested individually in unit testing before integrating the components. Here is a rule of thumb that i use for integration testing. The integration tasks require that the software design, development.
