The following are the standards of integration testing :

1. Integration Test plan has to be signed off by the test manager prior to testing
2. Test cases has to be designed and approved prior to testing
3. Defect classification has to be done prior to testing
4. Test templates has to be designed and approved prior to testing
5. Test evaluation needs to be given at most importance
6. Test control activities has to be identified
7. Test reporting needs a standard convention to write test report
8. Look for problems with data exchange format problems
9. ­Module invocation sequence problems
10. ­Module synchronization problems­
11. Module response time problems

Recommended Practices

1. Test plan has to be prepared and signed off by the test manager prior to testing
2. Test cases has to be designed and approved prior to testing
3. Defect classification has to be defined prior to testing
4. Standard Test templates needs to be designed and approved prior to testing
5. Test evaluation needs to be given at most importance
6. Test control activities has to be identified and regularized
7. Test reporting needs a standard convention to write test report
8. Review of test reports has to be done at regular intervals

Integration Testing Approaches:

1. Incremental approaches

i. Top-down

ii. Bottom-up

iii. Sandwich

2. Non-Incremental approaches
