System Integration Testing

The chief purpose of SIT is to ensure that all modules and sub-systems work co-dependently and interact together without any defects or failures.

Often, individual systems will work perfectly fine in isolation. SIT, however, guarantees that all elements are integrated successfully as a complete system to minimise risks.

At Prolifics Testing, our experts test the logic, sequencing, exception handling, and process decomposition that cover various systems. Our experience helps the development team to make adjustments before implementing the complete system, thereby saving time and money.

A strong SIT strategy involves automated alerts, reporting, and provision of other vital information, so that data can be accessed and updated as easily as possible. SIT is based on multiple test design techniques, like use case testing, state transition testing, load testing, usability testing, volume testing, graph-based testing and decision table testing.

After setting out our Agile sprint model, we encourage our clients to conduct SIT before release. Defects found are then sent to the development team to fix all issues. After that, the SIT test phase moves to User Acceptance Testing (UAT), the final stage of functional testing.


System Integration Testing is performed to achieve these benefits:

  • Detect defects early
  • Get early feedback on the user acceptability
  • Schedule defect fixes
  • Correct data and control flow
  • Rectify timing
  • Revise memory usage
  • Improve software requirements
