Test Runs
Profile used for testing - Default - Create Holdings and SRS MARC Holdings
| Set of tests № | Scenario | Test Conditions |
|---|---|---|
| 1 | DI Holdings Create (previous* approach) | 1K, 5K, 10K, 80K sequentially |
| 2 | DI Holdings Create (new** approach) | 1K, 5K, 10K, 80K sequentially |
*previous approach - Data import Holdings with mrc file where 1 instance HRID is associated to all holdings (1k, 5k, 10k, 80k)
**new approach - Data import Holdings with mrc file where 1 instance HRID is associated to 1000 holdings
